268 CORTICICOLINA. 



middle, and with a wide, transverse depression, deepest on tlie sides. 

 Scutellum large, broad, base straight, sides and apex rounded in a con- 

 tinuous curve. Elytra laid over each other within the connexivum, 

 not so long as the abdomen ; base narrow ; anterior margin nearly 

 straight, a little widened and sinuate at the base ; Corium very 

 short, sub-triangular, merging into the broad membrane ; close to 

 the base and anterior margin a lanceolate, concave cell, from the inner 

 side of which a nerve extends posteriorly and is lost in the mem- 

 brane ; between the cell and the nerve a furrow which gradually 

 becomes shallower; below the scutellum a transverse depression 

 extends between the nerves on each elytron. Sternum depressed in 

 the region of the coxse, the segments quadrangular. Legs ; thighs 

 clavate ; ^z52'(S angulated, widened to the apex ; tarsi; 1st joint very 

 small, 2nd widened to the apex. 



Abdomen ; Abdominal segments above and beneath, in both sexes, 

 6 visible ; all except the 1st long, the 1st 4 with straight margins ; 

 5th on the posterior margin slightly concave ; 6th above, reflexed, 

 convex in the middle, its posterior margin deeply concave ; in the ^ , 

 the 6th segment beneath, is deflected, convex in the middle, pos- 

 teriorly, deeply, transversely crenate, the posterior margin nearly 

 straight; in the ? , the 6th segment, above, has the posterior margin 

 less deeply but more widely concave than in the (J, the margin of 

 the excision thickened and raised ; on the underside flat, posteriorly 

 crenate as in the (^ ; the posterior margin slightly produced in the 

 middle ; Connexivum very broad, horizontal, the inner side straight, 

 outer side rounded. 



Genital segments. In the ^ , above and beneath, 2 only are visible 

 — one, long, broad, convex, rounded at the end, projects far beyond 

 the end of the abdomen ; the 2nd represented by a very small obtuse 

 point at each side of it. In the $ , above, the excision on the pos- 

 terior margin of the 6th abdominal segment is filled by the 1st geni- 

 tal segment, which is convex on the upper surface, and rounded be- 

 hind ; beneath, only the narrow truncate apex of the last segment 

 is visible.
