China, pi. 15, p. 31. Hong Kong, China. This species varies in the shape 

 and direction of some of the nerves of the hemelytra, and in the coloring, par- 

 ticularly of the wings, but a comparison of the genital organs, &c, will satisfy 

 any one of the identity of the species.

Length to tip of abdomen 6^ lines. Alar expanse 15 lines. 



Hab. Hong Kong, China. 



The front is traversed by about seven transverse ridges, and the longitudi-
