Length 7 mm. 
Bab. Ceylon : Colombo. 
Suffrian also compares this species with C. seocsignatus , of which 
no variety has been described in which the elytra have four spots 
instead of three, although such of course may exist. 
458. Crypto cephalus corrosicollis, sp. n. 
S • Testaceous ; terminal six joints of antennae black ; elytra 
with extreme sutural margins and a small humeral spot black. 
$ . Head with a central black band ; elytra with two spots at 
base and one behind the middle black. 
Head deeply longitudinally grooved at vertex, very finely rugose 
and punctured ; clypeus triangularly emarginate, finely pubescent ; 
eyes deeply subquadrately emarginate ; antennae rather short and 
robust, basal five joints testaceous, rest black, first joint thick and 
short, second very small, third twice as long as second, fourth and 
following gradually lengthened, scarcely widened. Thorax one- 
half as broad again as long, strongly convex, sides rounded 
anteriorly, not much narrowed in front, surface minutely punc- 
tured and entirely covered with extremely fine transverse wrinkles. 
Scutellum margined with black at base, the latter foveolate. 
Elytra narrowed posteriorly, deeply punctate-striate, interstices 
slightly costate, entirely covered with fine rugosities ; epipleural 
lobes slightly angular. Body beneath very finely pubescent, 
testaceous, breast slightly fuscous ; legs robust. Prosternum 
strongly produced anteriorly and hollow. 
The female differs in having three elytral spots, two elongate 
at basal margin, closely approximate, and one transverse behind 
the middle between second and seventh rows of punctures. 
Length 2|-3 mm. 
Ilab. India : Pusa. 
The peculiar sculpture of the thorax will easily distinguish this 
species.
