Although we have no definite adult record for this species in Illinois, there is consider- able suspicion that the larva of the genotype might be Genus A described below. This larva was found in the stream at Parksville, Tennessee, along which the type series of the genotype was collected. Hydropsychid Genus A Larva.—Fig. 338. Head bright brownish yellow with a few darker suffusions along the frontal area; thoracic shields and legs brownish yellow with irregular darker markings. Head with gula small and tri- angular, frontal area without prominent carinae; mandibles stout, fig. 282, the left.
