JORDAN—COLEOPTERA: ANTHRIBIDA 265 
densely pitted all over with grooves, which give it a reticulated appearance. The carina 
is antebasal, but not very remote from the base, being straight above with a faint 
curve backwards in the centre; laterally it is flexed forward in a large curve and 
reaches the apical margin at some distance below the eye. The elytra are as broad 
as the prothorax and more than half as long again. They are cylindrical, coarsely 
rugate and punctate-striate, and bear distinct humeral callosities. In spite of the 
coarse structure of the derm, both the upper and under surfaces of the species are 
glossy. The first segment is about half the length of the fourth segment in all the tarsi; 
the claws have a distinct tooth. ;

é?. Chorago valde affinis, carina prothoracis basali.—Genotypus : A. tener, spec. nov. 
One elongate species. 
The mandible bears an acute tooth near the apex. ‘The eye is large, lateral, 
coarsely granulose and round. The antenne are slightly longer in the g¢ than in 
the ?, segments 1 and 2 are incrassate as usual in this group of genera, 3 to 8 are 
almost alike in length, the club is but very slightly compressed, the segments being 
separate but not much stalked, 9 and 10 obliquely truncate at the apex, 11 subglobular. 
The pronotum is less convex than the elytra; the carina is basal and is continued to 
centre of the sides, forming an obtuse lateral angle, this lateral carina is less elevated 
than the dorsal one. The elytra are elongate and cylindrical; the suture is not 
depressed, the basal margin very slightly imcurved from shoulder to shoulder, being 
almost straight. Legs as in Choragus; hind tibia with some stiff bristles dorsally at 
the apex. The teeth of the claws long and slender. The prosternum is short; the 
antecoxal portion being scarcely as long as the diameter of the eye.

é?.  Rufo-brunneus, ore, antennarum funiculo, tibiis tarsisque luteis, pube alba 
vestitus, sutura nigricante, maculis rufo-brunneis seminudis notatus; prothorace den- 
sissime punctato-reticulato, elytris sat dense punctulatis. 
Long. (cap. excl.) 1°6—2-2 mm. 
A small series. 
The white pubescence consisting of rather broad flat appressed hairs is not very 
dense anywhere, but nevertheless rather conspicuous on account of its colour. The 
brown patches, which vary in extent, are as follows: a very large central patch on 
the pronotum, reaching from near the apical margin to the carina and divided medianly 
by a white ill-defined stripe, which is interrupted in some specimens, at the sides 
often a smaller patch; a very large dorsal area on the two elytra together, rounded, 
ill-defined, enclosing on each elytrum a white postmedian spot ; moreover, each elytrum
