Peltis, Fabricius. 



This genus I have included along with the 

 Silphidse, although Mr. Kirby considers it as a 

 distinct family. Of four species described by Fa- 

 bricius three belong to the genus at present; the 

 fourth is a Thymalus\

C. Erythrocera, Germar. 



The above genera, according to my views, belong 

 to the family Imatidiidae, and others might un- 

 doubtedly be added. It seems remarkable that 

 Fabricius should have located Imatidium between 

 Silpha and Nitidula ; as however it is difficult to 

 account for his arrangement in the present instance, 

 I proceed to characterise the genera belonging to 

 the above family. 



Calopepla, Hope. 



Typus C. Leyana, Olivier. Caput subrotundatum 

 vertice compresso. Antennae conspicuae Thorace 

 duplo longiores articulis compressis, ultimis externe 

 crassioribus et inter oculos insertis. Thorax brevis
