Craighead (1923) described the larvae of four North American species of Acunthocinus and constructed a key for their separation; two of these, A. nodosus (Fab.) and A. obsoletus (Oliv.), occur in the eastern half of the continent. During recent studies of cerambycids infesting fire-killed pine in central Ontario, another species, A. pusillus Kby., was encountered in large numbers, but the larvae could not be identified because of the lack of a published larval description. Larvae were eventually reared from known parent adults, and, since wood-boring Coleoptera are most frequently encountered in immature stages, the following description has been prepared.

The North

Relatively little is known of the life history, ecology and behaviour of most species of Tabanidae. Knowledge of their immature stages is particularly deficient. The larvae of only 46, or about ⅛, of the North American species have been described and many of these descriptions are inadequate. The present research was initiated in 1960 to describe and classify tabanid larvae and to contribute information on larval habitats and life histories.

In the course of our studies of the Trichoptera of the southern Appalachians during the past few years, considerable material of the genus Lepidostoma has been accumulated. In addition to range extensions and previously undescribed females in various groups within the genus, this material has provided four new species in the vernalis group. With the number of species in this group thus doubled, we believe it useful to provide here a revision of the whole vernalis group, with keys to the males and females. Knowledge of the immature stages is not adequate to permit any systematic analysis at this time.

Taxonomic Changes

Phylogeny of Polycentropodidae Ulmer is inferred based on data from immature and adult stages. Larval information is unknown for 61% of the taxa included in this study. To understand the effects of including characters with large sets of missing data, three alternative datasets were analysed using parsimony and Bayesian methods. Five outgroup taxa, including the four families in Psychomyioidea and the single family in Hydropsychoidea, were used in all datasets. Monophyly of Polycentropodidae, as currently defined, was rejected and the monophyly of the three largest cosmopolitan genera, Polycentropus, Polyplectropus and Nyctiophylax, was not confirmed. Monophyly of Pseudoneureclipsinae, including the genera Antillopsyche and Pseudoneureclipsis, was supported in all analyses. The placement of Pseudoneureclipsis within Dipseudopsidae was rejected. Monophyly of Kambaitipsychinae was supported, but its placement within Polycentropodidae was not confirmed. Analyses were sensitive to either inclusion or exclusion of characters from immature stages. Based on the results of these analyses, the following taxonomic changes are established: Kambaitipsychidae, stat. nov. and Pseudoneureclipsidae, stat. nov. are elevated to family status. North American Polycentropus species originally described in either Plectrocnemia or Holocentropus are returned to their original combinations and North American species described in Polycentropus post-1944 are transferred to either Holocentropus or Plectrocnemia. The following new or reinstated combinations are proposed: Plectrocnemia albipuncta Banks, comb. rev.; Plectrocnemia aureola Banks, comb. rev.; Plectrocnemia cinerea (Hagen), comb. rev.; Plectrocnemia clinei Milne, comb. rev.; Plectrocnemia crassicornis (Walker), comb. rev.; Plectrocnemia jenula (Denning) comb. nov.; Plectrocnemia icula (Ross), comb. nov.; Plectrocnemia nascotia (Ross), comb. nov.; Plectrocnemia remota (Banks), comb. rev.; Plectrocnemia sabulosa (Leonard & Leonard), comb. nov.; Plectrocnemia smithae (Denning), comb. nov.; Plectrocnemia vigilatrix Navás, comb. rev.; Plectrocnemia weedi (Blickle & Morse), comb. nov.; Holocentropus chellus (Denning), comb. nov.; Holocentropus flavus Banks, comb. nov.; Holocentropus glacialis Ross, comb. rev.; Holocentropus grellus Milne, comb. rev.; Holocentropus interruptus Banks, comb. rev.; Holocentropus melanae Ross, comb. rev.; Holocentropus milaca (Etnier), comb. nov.; and Holocentropus picicornis (Stephens), comb. rev.

In July and August 1929 the writer's father, Mr D. K. Kevan, found large numbers of a species of Lymnœa, cleaned out of a warm engine-pond in a timber yard in Leith. These snails showed much variation in the form of the shell, and this made identification difficult.In July and August 1940 the writer revisited the locality, collected a considerable number of living snails from the pond in question, and eventually established that they belonged to the common North American species, Lymnœa (Stagnicola) catascopium, Say.

While examining the collections of immature stages of Simuliidae made at Jasper, Alta., in 1932, by Mr. J. D. Gregson, Livestock Insect Laboratory, Kamloops, B.C., I recently found a female pupa of the rare and remarkable family commonly called “mountain midges”. The group consists of a single genus, Deuterophlebia Edwards (1922), in which four Asiatic and two North American species are recognized, although there are, also, a few records of unidentified larvae and pupae. Muttkowski (1927) first recorded the family on this continent, and Pennak (1945, 1951) and Wirth (1951) have described the two Nearctic species. Pennak (1945) has also summarized the published information on the distribution, habits, and morphology of the group.

Southeastern Coastal Plain

The genus Ectemnia Enderlein consists of four North American species, two of which are described as new. The two previously described species, E. invenusta and E. taeniatifrons, are primarily northern in distribution and their immature stages occupy rocky rivers. The two new species, E. primaeva and E. reclusa, occur in the southeastern Coastal Plain; their immature stages inhabit blackwater swamp streams and sandy rivers. Keys are provided for larvae, pupae, and adults. The polytene chromosomes of all species are analyzed in detail. Seven fixed inversions, 10 unshared autosomal polymorphisms, two centromere-band expressions, and five sex-chromosome systems are recognized among the four species. At least 10 synapomorphies indicate that the genus is monophyletic. Phylogenetically, Ectemnia is in a clade with Metacnephia and Simulium.

Larval and pupal stages have been associated and are described for western North American species in the caddisfly genera Pseudostenophylax and Philocasca. Diagnostic structures of the adults are described where they are necessary for a clear definition of the species.In the genus Pseudostenophylax, the larva of P. edwardsi (Banks) has been associated. It is described and shown to be identical with that designated by previous workers as Limnephilid Genus A. The diagnostic characters of the female genitalia in this species are illustrated for the first time. Observations on the habitat of this species are offered.In the genus Philocasca, larvae and pupae are described for two species, and the larva of a third, unassociated to species, is assigned to this genus and described. The rearing of a species not previously known, and here described in all except the egg stage, raises to five the number known in Philocasca. To bring the diagnoses for all of these species into a consistent form the holotype males of all have been reexamined, illustrated, and comparatively described. Females are associated and described for three species, representing the first information on the females in this genus. Diagnostic keys are provided for the identification of males, females, and larvae, insofar as these are known. New distributional records are provided for certain of the species but members of the genus as a whole must be regarded as extremely localized in distribution.
