or yellow. Head, thorax and scutellum slightly clouded with 

 yellowish. Elytra with a reddish tint on the coriaceous portion ; 

 membrane transparent, with a pitchy black spot at the internal 

 basal angle. (This spot is concealed by the tip of the scutellum 

 when the wings are closed.) Margins of the abdomen projecting 

 considerably beyond the elytra on each side. Abdomen beneath 

 reddish or testaceous brown, smooth, shining ; the disc sparingly, 

 the lateral margins very thickly and finely punctured. Breast 

 concolorous with the abdomen, sparingly punctured, more thickly 

 so at the sides. Legs reddish brown, punctured with black ; the 

 tarsi darker. Rostrum reddish brown, darker at the tip. An- 

 tennae of the same colour, the two last joints black, except at the 

 base. 



The species appears to vary a good deal, in the colour being 

 paler or darker, and more or less mixed with yellowish.

The fourth species is the Halys {Nevroscia) nubila, Fab. 



Of the Pentalomides there are also four species, of which two 

 appear to be undescribed. Those already described are the 

 Strach'ia limhata, Fab., a Javanese species, and the Indian Penta- 

 toma ventralh, Hope. Nearly allied to the latter is one of the 

 other species, for which I propose the name of —

Body roundish. Above olive-testaceous, opaque, thickly and 

 finely punctured with black. Head very thickly and rather 

 coarsely punctured. Eyes brown. Prothorax with the lateral 

 angles considerably produced on each side, but rounded at the 

 apex ; emarginate anteriorly for the reception of the head, the 

 posterior margin straight. The anterior portion of the thorax is 

 more thickly punctured than the posterior, with a faint transverse 

 line on each side near the anterior margin, and a very narrow 

 longitudinal line on the disc, smooth, impunctate. Scutellum 

 rather more faintly punctate towards the apex. Elytra with a 

 s.nall impunctate spot on the disc; the membrane transp; icnt.
