of separate spots. In the females of heliocausta Dognin the markings 

 of the hindwing are somewhat more scanty than in the males, and 

 only in the form baccheutis Meyrick of this species is the difference 

 less striking, because of the development of additional spots. A 

 careful comparison of the male specimens of buckleyi and the female 

 specimens of purpurea peiTnits recognition of common elements 

 in the markings of the hindwing. This is particularly convincing 

 in the specimens of both sexes, collected in the same locality 

 (Chiguinda) . 



The abdomen of the holotype of purpurea had been badly damaged, 

 probably at the time the specimen was caught or shortly after, 

 and the genitalia became lost. For this reason it has become necessary 

 to examine and photograph the female genitalia of a specimen other 

 than the holotype, but superficially similar to it. 



Pseudatteria (Eurynatteria) cantharopa (Meyrick) 



Plates 34-36 



The holotype of this species is a female with the abdomen missing. 

 The present author had the chance to examine two more female 

 specimens originating from the same locality as the holotype (Chulu- 

 mani, Bolivia) and well matching the latter. Moreover, he had at 

 hand six more specimens from Peru, similar to those from Bolivia, 

 but nevertheless distinct from them in some external characters, 

 constant in all of the examined specimens. The female genitalia 

 give no grounds for separation of the Peruvian moths as a species 

 distinct from cantharopa, but the external appearance permits treating 

 them at least as a subspecies.
