202 H. STEMPFFER 



Male genitalia (Text-fig. 173). Uncus composed of two oval lobes fused to the tegumen 

 and separated by the concave margin of the latter, subunci long and curved, gradually tapered ; 

 tegumen reduced ; vinculum broad above, narrow below ; lower fultura furca-like with two 

 curved, tapering arms ; valves oblong with spatulate and slightly serrate apices ; penis oblong, 

 slightly swollen at its base, vesica with a shagreened appearance ; apices of uncus and valves 

 pilose. 



With the exception of nubifer, all the species of Uranothauma have male genitalia 

 like those of crawshayi, only differing in the shape of the valves, which furnish good 

 specific characters and enable one to separate artemenes on the one hand, and on the 

 other, to associate lunifer with poggei. In nubifer the uncus lobes are smaller than 

 in other species, the subunci shorter, the tegumen is larger and its distal margin less 

 concave, and the upper part of the vinculum is expanded in the form of a triangle 

 directed cephalad. 



The early stages of nubifer, delatorum and falkensteini have been described by 

 Jackson, (1937, Trans. R. ent. Soc. Lond. 86 : 229-230). The caterpillars live on 

 species of Mimosacae, for nubifer, see also Pinhey, 1949 : ill.
