think that Bohemann's species is a good one, and so I 

 retain it. 



Genus XLIV.— DICKANEURA, Hardy. 



Vertex obtusely angular. Elytron longer than the 

 body. Nervures of the corium nearly parallel. Apical 

 areas four. Limbus wanting. First and second wing- 

 radials united before reaching the marginal vein, which 

 latter is complete. Third radial nervure forked, and 

 united by a short transverse vein with the second at 

 about its middle. 



This genus is equivalent to Notiis and Enjthria of 

 Eieber. The genitalia of the males are complex. The 

 elytral neuration is almost lost or invisible in some of 

 the species. The two forked nervures in the wing 

 give a meaning to the name of the genus.
