Genus Trichoprosopon, 



593 



Observations. — Redescribed from two (J's and one ? given 

 me by Dr. Lutz. 



It differs from others of this genus in the banding of the legs. 

 In this respect the $? does n °t agree with the <J , and I have 

 very strong doubts as to its being the same species. The <J 

 abdomen is strongly compressed laterally, the female is not. 

 There is a great play of colours over the whole body, so that 

 the banding of the legs had best be relied on to distinguish it.

fresh material. They were obtained from water between the leaves 

 of bromelias and at the base of banana leaves. 



The pupa shows very small terminal plates, and the two last 

 segments bear large tufts of hairs (24-26 and 14-16 respectively).
