In addition to the type and allotype we have before us a paratypic 

 pair, bearing the same data as the type. These specimens show no 

 differences worthy of remark. 



Eneopterinae. 

 Aphonomorphus major Chopard.

Igarape-assu. One female. 



This specimen is somewhat damaged and the form of the distal 

 palpal joint is not satisfactorily ascertainable, but in all other import- 

 ant ambisexual features our specimen agrees with the description of 

 major, which was based on the male. The dorso-internal margin of 

 the caudal tibiae has one more spine (six instead of five) than Chopard 

 gives, but this is probably a purely individual feature. 

 Aphonomorphus griseus Chopard. 



1912. A [phonomorphus] griseus Chopard, Ann. Soc. Entom. France, LXXXI, 

 p. 430, 2 figs. [La Forestiere, French Guiana.] 



Igarape-assu. January 17, 1912. One male. 



We are assigning this specimen here although it shows at least one 

 point of difference from Chopard's description. This is in the pres- 

 ence of but two, instead of three, spines on the dorso-external margin 

 of the caudal metatarsi. Our specimen has the body length slightly 

 greater than Chopard's measurement, and the distal palpal joint 

 seems rather elongate to answer the original ''aussi long que large." 

 However,- the features of agreement are so pronounced and the 

 features of difference those of possible individual variation, or of 

 exact interpretation of the proportions of a relatively difficult shape 

 to describe, that we consider our present course of reference best. 



Aphonomorphus surdus n. sp. (PI. II, fig?. 71-74.) 



Apparently allied to A. variegatiis and griseus Chopard, from Cay- 

 enne, and A. conspersus Bruner, from Bolivia. From variegatus it 

 differs chiefly in the different spination of the caudal tibiae, in the 

 different coloration, in the more elongate limbs, in the smaller ocelli, 

 in the greater general size, in the deeply sulcate subgenital plate of 

 the male, and in the fewer mediastine rami of the tegmina. From 

 griseus it differs in the greater general size, in the smaller ocelli, in the 

 lateral lobes of the pronotum being longer and shallower in propor-
