of some Hemipterous Insects from Boutan. 187 



transverse fovea, surrounded by a brassy green ring. Scutellum 

 very finely punctured, and faintly wrinkled transversely, especially 

 at the base, which is brassy, coppery or violet. Elytra brown, 

 with the margins pale testaceous. Margins of the abdomen pro- 

 jecting slightly beyond the scutellum, bright red, crenated, each 

 segment bearing two small projections or tubercles ; abdomen 

 beneath deep blue violet, very smooth and finely punctate, with a 

 strong brassy green reflection ; a violet line on the margin of each 

 segment, running between the red tubercles. Anal apparatus 

 red, violet at base in the male. Breast shining violet, punctured; 

 the antero -lateral margins and the prominent lateral angles red- 

 dish. Legs shining violet, finely pilose. Tarsi black. Antennae 

 and rostrum black, the former covered with short hairs. 



This species in its general form, and more especially in the 

 form and colouring of the abdomen, approaches very closely to 

 C Roylii; but it differs from this and indeed from all other 

 kno\vn species of the genus, in the sharp spines which exist at the 

 lateral angles of the prothorax. It is probable that the insect, 

 when alive, presents a most splendid appearance, as the metallic 

 tints, which ornament its surface when viewed in certain lights, 

 are evidently only the remains of former brilliancy. 



Three more species complete the list of Scutelleridce ; they are 

 the Eucorysses Baro, Fab. ; Calliphara nobilis, Fab. ( Tectocoris 

 perplexa, Hope) ; and the Coptosoma crihrarium, Fab. 



Fam. PENTATOMID^. 



Of the group Asopides, Am. Serv. there are but two species. 

 The first is the Caz'ira verrucosa, Westw. (not Am. Serv.), of 

 which there is a specimen of the male in the typical condition, 

 and one of what appears to be a black variety of the female. 

 The other species appears to be identical with the Asopus (Arma) 

 geometricus, (Hag.) Burm , and approaches very closely to Penfa- 

 toma aliena, Hope. As neither of the descriptions given by these 

 authors is sufficient to determine the insect perfectly satisfactorily, 

 I have subjoined one in a more detailed form.
