Agathymus escalantei Stallings, Turner, and Stallings, 1966 (Lepidoptera: Hesperiidae) is the only described species of Megathyminae known from a single collected individual. To date, the only images of this specimen are poor black and white illustrations published in the original description. This note presents the first color photographs of the holotype.

A new species of Physoconops Szilady, P. (Pachyconops) weemsi, is described from Florida and Georgia. It is similar to two other species in the southeastern United States, P. floridanus Camras and P. brachyrhynchus Macquart, the main differential character being the shape of the female theca. The female thecae for all three are illustrated and a key to the three related Pachyconops species occurring in the southeastern United States is presented.

Nomenclatural errors associated with the nymphalid butterfly, Speyeria atlantis greyi Moeck, have persisted in the literature and electronic databases. We present here a synonymy of the various combinations and misspellings associated with it and clearly indicate the correct name and spelling based on Moecks (1950) original description. Additionally, color images of the holotype and allotype specimens are published herein for the first time.

Published claims in 1887-1903 that the mole cricket Neocurtilla hexadactyla (Perty) occurs in Puerto Rico all seem to be derived from a misidentification made by Agustín Stahl, a medical practitioner and collector of natural history objects, published in 1882. That species does not seem now to occur in Puerto Rico and almost certainly never did. However, the opportunity still exists for it to colonize by wind-assisted flight from islands to the southeast just as we believe did the mole cricket Scapteriscus didactylus (Latreille) as an immigrant. Stahl evidently mistook the latter for the former. According to some subsequent authors, he also stated that it (the mole cricket now believed to be S. didactylus) arrived in the port of Mayagüez in a cargo of guano about 1850 from Peru and thus colonized Puerto Rico. We found no verification for that story, and we doubt it. The first detection of the presence of S. didactylus in Puerto Rico may have been by a French expedition in 1797, but this species may have been present much earlier. Two other species of Scapteriscus were later detected in Puerto Rico. One, S. abbreviatus Scudder, was detected in 1917 and likely arrived as a contaminant of ship ballast some time earlier, perhaps at the port of Mayagüez. The other, S. imitatus Nickle and Castner, was detected about 1940 and seems to have been introduced inadvertently, as a result of mistaken identity. In broad terms, S. didactylus, S. abbreviatus, and S. imitatus are adventive species (meaning they arrived from somewhere else and are not native) in Puerto Rico. The vernacular name changa in Puerto Rico is owned by S. didactylus, which is called West Indian mole cricket in the English-speaking Caribbean. Historical accounts suggest that populations of S. didactylus and of two pest Phyllophaga spp. (Coleoptera: Scarabaeidae) surged after 1876/1877 and declined after 1920. This coincidence suggests that the cause may have been the same. The cause of the rise might conceivably have been introduction of the mongoose Herpestes javanicus (E. Geoffroy St. Hilaire) in 1877 (because it may have destroyed vertebrate predators) and the cause of the decline might conceivably have been introduction of the toad Bufo marinus L. in 1920, because it is a predator of Phyllophaga and Scapteriscus.

Trypoxylon (Trypargilum) mexicanum (Hymenoptera: Crabronidae) belongs to the albitarse group, which includes the larger species of the genus. Its native distribution extends throughout Central America from Mexico to Panama. Here it is reported for the first time from Hispaniola, West Indies. Because it is difficult to envisage such a conspicuous species having eluded capture any naturalist or aculeate specialist previously, I consider that it has recently arrived on the island. It may have arrived due to the trade with Central America, since the nests, made of mud, can easily transport the immatures that subsequently emerge and disperse after their arrival on the island. T. mexicanum is established at least in the Dominican Republic, with a wide distribution and large populations. This demonstrates the ecological success of a recently established population on the island, perhaps due to escape from natural enemies and an absence of other limiting factors. The females were observed at puddles of water on the roads where they pick up mud with which they construct their tubular nests. Brood cells were provisioned exclusively with several species of spiders of Araneidae. An endemic spider, Eustala bisetosa Bryant was also used as prey. Other data about natural history is also provided.

Descriptions of pupal cases of Dialeurodes schefflerae, new species, as well as distribution records are presented. This species is known to occur in Florida, Hawaii and Puerto Rico appearing to feed only on species of Schefflera Forst and Forst. This restriction to plant hosts in the Asian genus Schefflera, along with its affinities with Dialeurodes agalmae Takahashi, Dialeurodes citri (Ashmead) and Dialeurodes kirkaldyi (Kotinsky), suggests it is an invasive species, probably endemic to the Asian region.

New locality records for Culiseta inornata (Williston) are reported from Big Pine Key, Grassy Key, and No Name Key in Monroe County, Florida. Five specimens were collected in dry ice-baited light traps. An old, previously unrecognized record for Anopheles grabhamii Theobald from Miami, Dade County, Florida, is reported based on specimens found in the Florida State Collection of Arthropods.
