p. 29. 



Pale flavous ; posterior margin of thorax, elytral suture and an 

 indistinct longitudinal mark on the posterior half, blackish. 



5 . Head with some irregular depressions and slightly marked 

 central line, emargination and clypeus finely and remotely punc- 

 tured, other portions shining ; mandibles black ; antennae more 

 than half the length of body, robust, fourth joint slightly longer than 

 third, following joiuts rather more slender. Thorax with posterior 

 margin serrate, black; surface impunctate, shining. Scutellum 

 raised, triangular, with large fovea at base, margined with black. 

 Elytra at base slightly wider than the thorax, still more widened 

 behind the middle; shoulders broad and flat; epipleural lobes rather 

 feeble ; surface finely punctured, the punctures still finer on the 

 apical third portion; interstices flat and broad, scarcely perceptibly 

 wrinkled ; extreme basal and lateral margins and the margins of 

 epipleurae black ; this black colouring is less distinct at apex of 

 suture but well marked at middle ; the shoulders are likewise stained 

 and an elongate obsolete streak placed behind the middle on the 

 fourth interstice. The following variety occurs : 



Var. a. Entire anterior portion of elytra with a transverse black 

 band, broad and ill-defined, extending in part anteriorly to the 

 epipleurae. Pygidium feebly carinate, finely punctured, yellow ; 

 anterior margin of prosternum bluntly produced, posterior angles 

 short and broadly pointed. 



Length 1 mm. 



Hob. Ceylon. 



Similar to C. indicus in size and shape but differs in the pale 

 coloration, the black elytral margins, the very fine punctures, and 

 the more elongate body. 



413. Cryptocephalus nigrosuturalis, sp. n. 



Above fulvous ; antennae, underside and legs black ; thorax 

 with two black spots, posterior portion of elytral suture narrowly 

 black. 



Short and ovate. Head sparingly but strongly punctured, more 

 or less deeply longitudinally grooved at middle of vertex ; clypeus 

 separated from face, wedge-shaped ; antennae with terminal six 

 joints distinctly widened, third joint one-half shorter than fourth, 

 not much longer than the second. Thorax short and transverse, 

 strongly narrowed in front, the sides straight, extreme margins 

 and posterior angles flavous, rest of disc fulvous, very minutely 

 punctured, a semicircular spot each side near anterior margin 

 black. Scutellum narrow and pointed, margined with black. 

 Elytra short, slightly narrowed posteriorly ; extreme basal margin, 

 a small humeral spot, and a very narrow sutural stripe from 

 behind the middle, black ; puucturation rather strong, distinct but
