nearly straight, a little emarginate above the scutellum. Scii- 

 tellum elongate triangular, with a line of fine punctures on each 

 side. Elytra rather short, a little narrowed posteriorly, Avith an 

 oblong impression near the side extending from below the 

 shoulder to a little beyond the middle, bounded on the inner 

 side by an obtuse costa, and on the outer side by a strong costa 

 which surmounts the deflexed portion of the side ; the suture 

 itself is deeply impressed, the margins of the impressions sub- 

 costiform ; the punctuation is rather irregular, but the larger 

 horse-shoe punctures are arranged in lines (crowded in the lateral 

 impression). The second, third and fourth segments of the 

 abdomen are a beautiful deep sky-blue. Anterior tilii.T with 

 three small teeth at the apex. Tarsi rather short.

• Eesembles Dirrhina iris, but with the head differently formed. 

 Clypeus nearly parallel sided, gently emarginate at the apex, 

 which is finely and closely punctured, with a longitudinal deep

 the lateral channel deeper posteriorly and extending to the 

 posterior angles. Elytra with a narrow transverse shallow 

 impression, a little behind the middle composed of very short 

 lines of strong punctures ; the suture from the middle to the

 the extreme base, and with two short, stout, aciniiinate, flexuous 

 horns, projecting over the insertion of the antenna' ; antenna) 

 scrobes deep, nearly I'caching the base of the rostrum, continued
