Antenna with 13 segments ; the first stout, clubbed ; third sub- 

 coiiical, shorter than the first; fourth and fifth shorter than third. 

 Head with sutures distinct. Pronotum short, broader than long, 

 truncate or concave anteriorly, rouuded posteriorly, often crescent- 

 shaped. Elytra ample, broad, the shoulders prominent ; costal 

 margin convex, with a strongly marked keel running the entire 

 length of the elytra; surface of the elytra rough, granulose or 

 punctulate. Wings generally prominent, sonielimes smooth, 

 sometimes resembling the elytra in texture ; sternal plates broad 

 and short. Legs long and slender. Abdomen depressed, dilated 

 about the middle, and narrowed again at the apex ; lateral tubercles 

 very distinct. Last dorsal segment of S very short and broad ; 

 of $ narrowed. Pygidium of J short, transverse, tumid, often 

 armed with a spine ;' of $ short, tumid. Forceps with the branches 

 in the c? remote at the base, slender, elongate, often sinuate in 

 the ventral plane and variously armed ; in the $ simple, straight, 

 slender.

This genus was erected by Verhoeff for Anediura hurjeli and 

 hrachynota ; a separate subfamily was actually formed for its 

 reception, which is not justifiable, as the keel of the elytra is the 

 only true character which really distinguishes it from Anechura. 



AH the known species occur in India.
