Chyranda new genus Adults.—General structure typical for family. Head without macrochaetae behind ocelli. Maxillary palpi very long in both Fig. 942. — Chyranda centralis cT, male, fig. 942, and female. Mesonotum with warts elongate. Tibial spur count 1-3-4. Apical segment of tarsi without black spines. Wings very similar in general aspect to those of Limnephilus, see fig. 636. Genotype.—Asynarchus centralis Banks. The very long palpi distinguish this genus from Limnephilus and others to which it is related. In the North American fauna this character will separate it from all genera which do not differ from it in wing vena- tion. Oligophlebodes Ulmer Additional material secured from various localities in the western mountains indicates that there are at least five species in this interesting genus. To a certain extent color characters have been found of some use in making identifications, but for the most part reliable differences are confined to the geni- talia. ¥ox the species so far differentiated, char- acters have been found to separate the fe- males to species as indicated in the key.
