ORIENTAL SPECIES OF OALLISTOMIMUS. 241 



as prothorax, weakly striate, the whole surface rather dull and 

 finely aciculate-punctate ; front fascia at a third from base, not 

 very wide, but widening outwards from stria 3 to margin ; hind 

 fascia at a third from apex, of about same width as front one, 

 widening from stria 2 to margin. Underside moderately 

 pubescent, last ventral segment more strongly so and trans- 

 versely subrugose. 



Distinguished from its congeners by its small prothorax, square 

 shoulders, and especially by the fact that the colour of the red 

 scutellary patch extends along the suture to apex. 



Laos: Pak Tha, Paklung and Ban Saleun, 16 ex. o* 2 

 (E. Vitalis de Salvaza). The type is in the British Museum. 



Oallistomimus virescens, sp. n. (Plate I. fig. 7.) 



Length 5 mm. Width 2 mm. 

 . Black. Head blue, prothorax red with purplish reflections on 

 upper surface, a sutural stripe on the elytra yellow-red, elytra 

 velvety blue-black with metallic blue-green lustre on shoulders 

 and along sides ; two fascia? on elytra (interrupted by the sutural 

 stripe) and apical margin, joints 1-3 of antennae, palpi (exc. apex), 

 front margin of labrum, and legs (exc. apex of femora) yellow- 

 white. 



Head (about PO mm. wide) convex, shiny, coarsely punctate 

 at sides, smooth and highly polished along median line and on 

 neck; maxilla? as long as mandibles. Prothorax very convex, 

 a little transverse, just wider than head, sides bordered and 

 strongly rounded, more contracted behind than in front, hind 

 angles in form of a minute right-angled tooth, with sides of base 

 advancing towards them, median line short but deep; surface 

 coarsely but not very closely punctate, faintly pubescent. Elytra 

 punctate-striate, intervals flat, punctate at sides but not evidently 

 so on disk, pubescent, base with a strongly marked border, region 

 of the shoulder irregularly punctate and rugose, epipleura; 

 coarsely punctate ; sutural stripe covering intervals 1 and 2 (more 

 or less), front fascia at a fourth from base, narrow, reaching 

 stria 6, "bind fascia at a third from apex, wider, reaching stria 9. 



Allied to C. suturalis Fit., but a little smaller, hind angles 

 of prothorax less evident, elytra more convex, sutural stripe 

 narrow at apex and lighter in colour, hind fascia much broader, 

 shoulders and sides much more rugosely sculptured. The very 

 coarse puncturation of the elytral epipleurae at once distinguishes 

 the species from its congeners. 



Burma : Tharrawaddy, 2 ex. 6 $ {G. Q. Corbett). The type 

 is in my collection.
