dilated anterior portion smooth at the sides ; the pleural grooves 
rather deep. Elytra moderately long, nearly twice as wide as the

The description is taken from a single example from 
eacli locality ; two others have been sent to the British 
Museum. Smaller, narrower, and less convex than A. 
segregatus ; the head much shorter and orbicular in shape, 
the eyes larger and more coarsely granulated ; the base 
of the elytra infuscate. The thorax has the appearance 
of being very obsoletely bituberculate at the base. 
Anthicus scahricollis, n. sp. (Plate VI., fig. 14.) 
Moderately elongate, convex ; the head and prothorax pitchy- 
red, opaque ; the elytra piceous or pitchy-black, shining, each with 
a rather broad transverse fascia a little below the base, widening 
outwardly and not reaching the suture, a narrower fascia beyond 
the middle, and sometimes the suture also, brownish or testaceous, 
these markings sometimes obliterated ; the antennae ferruginous, 
the legs testaceous ; finely pubescent, the elytra sparsely clothed 
with rather long decumbent hairs Head very large, greatly 
developed behind (the basal portion projecting over the apex of 
the prothorax when the head is horizontally extended), longitudinally 
convex, parallel at the sides behind the eyes, the hind angles 
rounded ; the base rounded at the middle and oblique towards the 
sides, the edge acute ; the surface closely punctured and scabrous; 
the eyes prominent, small, distant from the base ; antennae rather 
short, joints 9-11 wider than those preceding, 10 about as broad 
as long. Prothorax largely developed, considerably wider than the 
head, transversely convex ; the sides rounded in front, rapidly and 
obliquely converging behind, and slightly constricted just before 
the base, the constriction limited anteriorly by a short marginal 
tooth, the flanks grooved behind ; the surface closely punctured 
and scabrous. Elytra about two and one-half times the length of, 
and not much wider than, the prothorax, oval, very convex, 
sparsely, moderately finely punctate. Legs rather short, the femora 
clavate. Length 2^-3, breadth f-1 mm.
