towards the base, where it is rounded ; tips hioad, somewhat tiuncattd. 

 Hind wings not paler than the fore wings; veins strongly marked; dis- 

 coidal sectors very numerous. Length of the body 21 lines; of the wings 

 76 lines. 



The great length of the wings and the coriaceous fore wings dis- 

 tinguish it from all the preceding species. In the shape of the prothoriix 

 it much resembles B.fusiformis, but in the latter the fore wings are much 

 more rounded at the tips and the scapular area is less dilated.

The description of B. dubia is too slight to identify it with specimens 

 examined, but the Blabera here recorded agrees better with it than with 

 any other characterized species. The eyes are more remote from each other 

 than those of B. Brasiliana.
