CRYPTOCEl'HALUS. 193 



Head flat, greenish-aeneous at vertex, closely punctured, lower 

 portion black ; antennae extending to base of elytra only, basal 

 joint fulvous beneath, third and following nearly equal, terminal 

 joints widened. Thorax rather long, less than twice as broad as 

 long, strongly convex, entirely impunctate, very shining, metallic. 

 Scutellum broad, sides rounded, bluish. Elytra broad and rather 

 flat, somewhat widened towards apex ; epipleural lobes feeble ; 

 surface strongly punctate-striate, interstices finely transversely 

 wrinkled, flat, sides and apex broadly flavous, middle of disc and base 

 bluish. Prosternum rugose, scarcely produced in front, posterior 

 angles pointed. 



Length 3 mm. 



Hab. India (Coll. Belt/. Mus.). 



Smaller than C. metallicus, the thorax metallic green and the 

 abdomen flavous. There is only a single male specimen in the 

 Belgian Museum without precise locality. It is probable that the 

 elytra vary in being entirely dark blue, as the latter colour is not 

 well defined at the margins and the flavous portion shows some 

 darker stains. 



Elytra flavous or red with Hack lateral margins.

 black. 



Head distinctly and closely punctured, a small black spot at 

 vertex and another at base of antennae ; eyes widely separated at 

 top, acutely emarginate ; antennae rather short, basal five joints 

 flavous, rest black, third to fifth of equal length, terminal joints 

 slightly thickened. Thorax twice as broad as long, very convex, 

 impunctate, extreme .margins and two spots at middle of disc 

 black. Scutellum black. Elytra rather short and broad, finely 

 punctate-striate, the suture very narrowly, the lateral margins 

 more broadly, black. Body beneath and legs flavous, femora 

 stained with brown ; tarsi broad, nearly black. Prosternum sub- 

 quadrate, the posterior angles produced.
