116 COREINA. 



of tlie corium a long narrow cell. Sternum with a rostral channel, 

 deepest ou the metasternnni. Legs slender. 



Abdomen above concave ; the last segment in the (^ broadly 

 rounded behind, with a wide, shallow notch in the centre ; in the ? 

 the posterior margin deeply concave, produced exteriorly into a point. 

 Underside convex, the 6th segment retracted and squarely cut out 

 for the reception of the genital segments. Connexivmn not covered 

 by the elytra, very broad in the centre, reflexed in a curve, forming 

 a thin, triangular plate ; on the margin with a small triangular 

 notch at the junction of the 4th and 5th and 5th and 6th segments. 

 Genital segments in the ^J not visible above, but beneath one is seen 

 projecting through the last abdominal segment, long, convex, and 

 posteriorly rounded. In the $ , above, the last 2 segments are 

 visible, both projecting far beyond the points of the connexiviim ; 

 the former with its posterior margin very concave, on each side 

 produced into a lanceolate point ; the latter also produced posteriorly 

 into 2 lanceolate points, so that, including the points of the con- 

 nexivum, the body ends in 6 points : on the underside the 3 seg- 

 ments are visible, the 1st small, convex, and cap-like, resting pos- 

 teriorly on the 3rd segment ; at its sides the broad points of the 

 2nd segment project from under the last abdominal segment ; the 

 3rd segment projects from below the 1st in the form of a concave 

 plate with a ridge in the centre, and is posteriorly pointed, as on 

 the upperside.
