DiOTIMA. 



Head small, expanded behind the eyes, which are large, oblong, 

 and nearly entire, labrum nearly covering the strongly curved 

 mandibles ; maxillary palpi very long, the last joint dilated, trun- 

 cate ; antennae short, setaceous, the third joint longest, Prothorax 

 small, subquadrate, irregular. Elytra long, parallel, depressed, 

 rounded at the apex. Legs slender, coxae of the middle and an- 

 terior legs conical, approximate, their tibiae spined at the end ; 

 tarsi narrow, the first joint lengthened. 



This genus seems to belong to the Ceramhychn, although there 

 are certain points which suggest an affinity to the Lepluridce. I have 

 seen a male without antennee ; the description is from a female.
