Phaenoserphus, Kieffer. 

 Kieffer, 1909, lists 32 species from widely distant habitats.

Family BELYTIDAE. 

 Few species have been obtained, and of these most fall 

 into new genera. More males have been collected, but were 

 left entirely alone, as it was thought they might belong to 

 wingless females yet to be discovered. Kieffer has erected many 

 genera on the male sex only, which does not seem a wise plan, 

 as wingless females are probably more numerous than has been 

 supposed, and would possibly differ greatly from their males. 

 Where sexes differ greatly in family or group it seems prefer- 

 able to use one only as the stable sex for generic erections. 

 The Australian genera, on the whole, appear to possess less 

 wing venation, as compared with the already known forms 

 ^rom other countries.
