terminal article not bearing a claw. The extra article of the anal 

 legs is at least strongly simulated on all the other legs, but especially 

 the more posterior ones, by a contracted terminal division of the 

 tarsus which for the most part is clearly distinct. (Plate 6, fig. 7). 



Genotype. — Schizojiamjya manni, sp. nov. 



This interesting genus is the second of the Chilenophilinae to be 

 reported from Brazil, Ribautia being the first. Taiyuna, recorded 

 from British Guiana, is the only other representative of the group 

 at present known from South America. 



Schizonampa may readily be separated from the other known 

 genera of the Chilenophilinae lacking a claw on the anal legs and 

 having the small additional distal article as shown in the following 

 key. 



Key to Genera of Section embracing Schizonampa. 



a. Ventral pores present; distomesal angle of coxa of second 

 maxillae prolonged; first maxillae without lappets. 



Proschizotaenia Sil vestri . 



aa. Ventral pores absent; distomesal angle of coxa of second 



maxillae not prolonged; first maxillae with lappets. 



b. Pores occurring as two large pits on each coxopleura; femur 



and tibia of second maxillae prolonged into an acute, strongly 



chitinized process at distoectal angle. . Schizonampa, gen. nov. 



bb. Coxopleural pores small and isolated; tibia not prolonged at 



distoectal angle. 



c. First maxillae with two long membranous lappets on each 



side WaiophUus Chamberlin. 



cc. First maxillae with but a single lappet on each side, this 

 being borne on the femur AUoschizotaenia Brolemann. 



Schizonampa manni, sp. nov. 



Slender; sides of bod}^ nearly parallel over most of length, but 

 conspicuously attenuated at caudal end and moderately attenuated 

 toward head. Body sparsely hirsute with short hairs; hairs of legs 

 few, those present commonly arranged mostly toward the distal ends 

 of articles. 



Color of body very pale, whitish yellow, the yellow being very dilute. 

 Head with basal plate, prosternum, and prehensors, darker, somewhat 

 light orange or dilute ferruginous; the antennae also similar.
