petiole ; hind femora armed with moderate-sized teeth ; wings 

 more or less clouded, with the uervures very strongly marked.

Birhinus, Dalm. Yet. Akad. Handl. 1818, p. 75. 



Birrhinus, Dalm. Anal. Ent. p. 29 (1823). 



Type D. excavaUis, Dalm. II. cc, from Sierra Leone. 



Antennae 12-jointed, inserted in the middle of the face, gradu- 

 ally thickened neai^ly to the extremity ; head very deeply exca- 

 vated, with a long projection in front within the eyes ; scutellum 

 unarmed, but metathorax strongly bidentate behind. 



The details figured are taken from a specimen without locality, 

 which agrees with King's figure of D. excavatus from Egypt 

 (Symb. Phys. pi. xxxvii. fig. 14). Whether it is identical with 

 Dalman's insect from Sierra Leone cannot be ascertained in the 

 absence of specimens from the latter locality.
