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

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

 side. Elytra rather short, a little narrowed posteriorly, with 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 tibiae with 

 three small teeth at the apex. Tarsi rather short.

Resembles 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 

 channel on each side, this channel is longitudinally finely 

 strigose. Thorax as in D. iris, but not quite so flat, and with 

 the lateral channel deeper posteriorly and extending to the 

 postei'ior angles. Elytra with a narrow transverse shallow 

 impression, a little behind the middle composed of very short 

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

 impressed line ; the extreme lateral margins and apex are rather 

 strongly striolate-punctate. Pygidium very closely and finely 

 striolate.

 little narrower at the apex, deeply channelled above, thick at 

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

 horns, projecting over the insertion of the antenna? ; antennal 

 scrobes deep, nearly reaching the base of the rostrum, continued 

 anteriorly by a slight channel. Antenna? as long as the rostrum,
