412. Cryptocephalus prascox, Suffr. Monogr., Linn. Eat. xiv, 1860, 
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 joints 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 
epipleurse 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 
epipleurse. Pygidium feebly carinate, finely punctured, yellow ; 
anterior margin of prosternum bluntly produced, posterior angles 
short and broadly pointed. 
Length 7 mm. 
Hob. Ceylon. 
Similar to 0. 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 ; antennas, 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, sligh fly narrowed posteriorly ; extreme basal margin, 
a small humeral spot, and a very narrow sutural stripe from 
behind the middle, black ; puncturation rather strong, distinct but
