MUNARIA RITSEMAË. 57 



terstices narrow , the alternating ones and the sutural one 

 raised in a keel, the outer keel united at the apex with 

 the first interstice from the suture, the remaining ones do 

 not reach it. — Anterior coxae contiguous, the cotyloid 

 cavities closed behind , the posterior coxae approximate , 

 the tibiae enlarged at the apex on the outside in the 

 shape of a tooth , tarsi simple , short , as in Colydium. — 

 The first ventral segment not longer than the following 

 segments, all, excepting the two last and the apical mar- 

 gin of the segments, with a strongly warted punctuation. 

 Antennae and legs finely pubescent. 



This genus must be placed next to Colydium, from 

 which it is however essentially distinguished by the con- 

 tiguous anterior coxae and the shape of the antennae. — 

 The species is dedicated to Mr. C. Ritsema Cz.
