AbstractThe North American Aegeriidae are revised on the basis of the study of late-instar larvae of about 60 species. These species represent 20 genera in five tribes in two subfamilies: Bembeciini, Zenodoxini, Aegeriini and Melittiini in Zenodoxinae and Synanthedontini in Synanthedontinae. The presently recognized genera, Ramosia Engelhardt, Conopia Hübner and Thamnosphecia Spuler are reduced to synonyms of Synanthedon Hübner. Three new genera are defined by larval characters but are referred to only as Genera I, II and III. Larval characters for most of the species are discussed and illustrated; keys to species, genera and tribes are provided. Tribes, genera and most species are arranged in the text as nearly as possible according to their phylogenetic relationships as suggested by the larvae.

Contrary to ideas that Cretaceous fresh waters contained few teleosts, there were several taxa of Esocoidei (pikes and relatives) in North American Cretaceous rivers. Dentaries and palatines of Campanian to Maastrichtian age all have C-shaped tooth bases and other distinctive features of shape and foramina. The fossils include at least three distinct kinds, two of which are described here as new genera and species in the Esocidae: Estesesox foxi n. gen. and sp. and Oldmanesox canadensis n. gen. and sp.These old, diverse, and apparently primitive specimens show that pikes radiated when Eurasia and North America were still joined. Some references in the literature to the Cretaceous fish Platacodon Marsh are based on referred dentaries that are here identified as esocoid fossils. The Esocidae are the first example of a family of Recent North American freshwater teleosts that has been shown to have speciated in Cretaceous fresh waters and survived the terminal Cretaceous extinction.

Brachynemurus Coquilletti, new species.Male.—Length, 33 mm.; expanse of wings, 44 mm.; greatest width of anterior wing, 5.6 mm.; length of antenna, 6 mm.; luteous, marked with dark fuscous; clothed with white hairs, thickly so on abdomen; apical segments of abdomen with some black hairs among the white ones.Face flat, luteous, bordered above by a pitchy-black band separating the antennae and narrowly bordering them in front and on the outer side; a longitudinal median black line extends from this band almost to the clypeus. Circum-ocular area luteous, except along the anterior portion of the vertex, where it is fuscous, and on the margin next the eye, opposite the middle of anterior joint of maxillary palpiger, where there is a fuscous spot. Clypeus rather short, luteous, on either side anteriorly an impressed spot; above, a few black bristles. Labrum transverse, luteous; rounded laterally and narrowed anteriorly, nearly straight in front, where it is sparsely clothed with light-coloured hairs. Mandibles piceous, black at tips.
