GENUS EEIOCAMPA. 219 



costa. It agrees, however, so closely in coloration 

 with the black species of Poecilosoma that it is best 

 included in that genus. From P. sulmuticum, with 

 which it has perhaps the greatest resemblance, it is 

 easily known by its more pilose thorax and head, much 

 shorter and thicker antennas, more perpendicular 

 transverse radial nervure, slightly shorter metatarsi, 

 as well as by the black pronotum and much thicker 

 stigma.

Genus EKIOCAMPA. 



Eriocampa, Htg., Blattw., 279. 



Wings with two radial and four cubital cellules ; the second and third 

 of the latter receiving each a recurrent nervure. Lanceolate cellule 

 with an oblique cross nervure. Accessory nervure largely appendicu- 

 lated. Hind wings with both the recurrent and transverse cuoital ner- 

 vures present, or the former only. 



Eyes not reaching to the base of the mandibles. Clypeus incised or 

 truncated. 



Antenna short, the third joint much longer than the fourth ; the 

 apical joints attenuated at the apex ; the middle ones thickened. 



Claws bifid at apex. Patellae developed only on the apical joints of 

 tarsi. 



Body ovate, short. 



The species are small, with short, thick bodies, with 

 black, shining bodies and legs, the latter having the 

 tibiae and tarsi annulated with white at the base, or 

 more or less testaceous, or dull white. In only one 

 species is there any red. The posterior wings have 

 either two middle cellules, in which case the clypeus 

 is incised at the apex, or they have one only when the 

 clypeus is truncated. 



Eriocampa has the small, thick-set body form of 

 Blennocampa> from which, however, it differs in the 

 form of the lanceolate cellule and of the antennas. In 

 the form of the lanceolate cellule and partly in the 

 neuration of the hinder wings it agrees with Poecilo- 

 soma, but that genus has the body longer and more 

 cylindrical, the antennas not thickened in the middle.
