889. Copelatus perfectus, n. sp. — Ovalis, sat depressus, piceus, capite piceo- 

 testaceo, prothoracis lateribus, elytris, antennis pedibusque testaceis ; capite trans-

 pi'ofundis, aliaque marginali abbreviata. Long, ih, lat. 2i m.m. 



Though allied to Colymbetes aubei (No. 896), the present species is quite distinct 

 by the smaller size, paler colour, and by the eleven instead of twelve-striate elytra. 

 The sexes are very diflScult to distinguish.

In the male the anterior tibiae are curved at the ii^nee and have a slight notch 

 there, the front and middle tnrsi are dilated, but narrow. The specimens I have 

 seen of this species are few in number, and are all in excessively bad condition, but 

 the marginal stria not abbreviated in front while the sutural one is shorter behind 

 than the others, the other stria\ nine in number, continued till near the apex, except
