Head finely aud thickly punctured between the eyes, palpi black. Thorax 

 nearly opaque, disc even, the middle channelled throughout its length, hind angles 

 acute, and not much more produced in the male than in the female ; sides sinuous, 

 narrowed towards the front. Elytra a little shining, very finely and obsoletely pimc- 

 tured, and finely coriaceous between the pimctures, of a dull leaden black, the usual 

 yellow spots are transverse and rather irregular in shape, the hinder one being more 

 quadrate than the front one : their sides are almost parallel, but slightly widened 

 (in the male) tUl near the apical spot, the apex of each is rounded separately. In 

 the female the sides ai-e narrowed from the middle, and the apical portion of the 

 elytra is depressed and produced in a manner I do not observe in any other species 

 of the genus, but which (in a less degree) may be seen in convexieollis, $ . Antennas 

 black, rather long. Legs pitchy-black, apical half of the femora testaceous.

This Bpccies comes in the same section as pulcJiripes, Gerst., but 

 cannot be confounded witb it. It is considerably larger, the legs are 

 differently coloured, the tooth on the anterior tibiae is larger and stands 

 out, and is also helow the middle, not above as in that species.

Head slightly shiuing, with a few scattered punctures, and with the mouth- 

 organs entirely black. Thorax hardly wider than long (if the anterior angles are 

 included), opaque, disc uneven, the usual impressed sulci and basal line, and a chan- 

 nel in the middle reaching neither base nor front margin. Elytra opaque, black (in 

 my specimen with a faint greenish tint), with scattered, obsolete and flat-bottomed 

 punctures, margin with larger ones, sub-quadrate, and very convex ; under-side of 

 body and legs shining, entii-ely black. Antenute black, with the club (which is clothed 

 with a fine pubescence) wholly testaceous. 



Hah., Peru. In my own collection, from Deyrolle. 



This curious Corynomalus is unlike any species in the genus ex- 

 cept tarsatus, Er., of which I thought it might bo a variety. The 

 examination of a specimen of tarsatus brought by Mr. Edward Bartlctt 

 from Peru, enables me to describe it as quite distinct. From tarsatus 

 it is readily distinguished by having the tarsi black, and the loliole of 

 the club of the antennic red, as well as by its general colour. I have, 

 I believe, seen it in other collections with the elytra bluer than in my 

 specimen.
