110 COREINA. 



Abdomen above flat; the last segment in the $ posteriorly 

 broadly rounded ; in the $ the posterior margin deeply concave ; 

 beneath very convex within the connexivum ; the last segment, in 

 both sexes, retracted and posteriorly deeply cut out. Connexivum not 

 covered by the elytra, reflexed, very broad, gradually widened and 

 then narrowed, ending in a short, subacute point. Genital segments 

 in the $ not visible from above, but beneath one, elliptic and 

 convex, projects through the last abdominal segment; in the 9, on 

 the upper side, two segments are visible, short, and not so wide as 

 the last abdominal segment, their posterior margins concave, of the 

 last one so much so as to form 2 obtuse points, which project beyond 

 the last abdominal segment ; on the underside the last segment is 

 reflexed posteriorly, and the anterior margin in the centre is covered 

 by the cap-like 1st segment, at the sides of which only the pro- 

 jecting points of the 2nd segment are visible.
