LEPXOMIAS. 



Leptomias, as here defined : (1) the metasternum is fused with its 

 episterna, so that the suture has disappeared except close to the 

 hind coxfe ; (2) the corbels of the hind tibiae are entirely open. 



The distinctions given by Eaust for his genus Heteromias are 

 that the scrobe is not dilated behind, and that the metasternum is 

 shorter than the median coxas. But these characters occur inde- 

 pendently in various species which he himself referred to Leptomias, 

 and the genus therefore cannot be retained. For similar reasons 

 I am unable to recognise the genns Parisomias, Fst. It may ba 

 noted that the generic name Heteromias was originally used without 

 description and even witliout any mention that it was considered 

 to be a new genus (Stettin. Ent. Zeit. 1888, p. 285).
