long, rounded at the sides posteriorly ; sinuate-truncate and

excavation limited externally by a long, stout, inferiorly-

Hab. Ruopesta, Salisbury (Dr. Marshall: x. 1899). 
One specimen. A _ rufo-testaceous insect, with opaque, 
purplish-violaceous elytra, the latter strongly bidentate at 
the apex in @, the five outer joints of the antenne partly 
or wholly black. #.(Miais) rufithorazx, Pic, §, has a similar, 
but shorter, conical tubercle at the outer apical angle of the 
elytra. The outer tubercle in H. conigerus is hook-like 
when viewed in profile.

6. Elongate, widened posteriorly, very finely pubescent, 
the head and prothorax very shining, the elytra (except at 
the base) opaque ; obscure metallic green, the sides of the 
prothorax broadly, and the abdomen (the black tip excepted), 
rufo-testaceous, the antennal joints 1-4 (except 1 above), 
and the anterior tarsi at the base, testaceous, the rest of the 
anteunz black. Head barely as wide as the prothorax, 
almost smooth, bi-impressed in front ; antennz long, ser-

covering the abdomen, very finely shagreened and with an

bordered on each side behind by a rather broad, tumid, 
projecting lamella. Anterior tarsal joint 2 extending over 
the base of 3. 
Length 33 mm.
