ferruginous. Legs reddish-testaceous. Length 6.5 mm. 

 Head shining, moderately finely and moderately closely 

 punctured, the temples impunctate but strongly coriaceous. 

 Antennae with the 2nd and 3rd joints of equal length, 4th 

 and 5th as long as broad, 6th to 10th transverse, 8th to 11th 

 almost forming a club. Thorax transverse, the anterior 

 angles rounded, the sides in front feebly rounded, behind almost 

 straightly narrowed to the rounded posterior angles which are 

 explanate, disc with a narrow impunctate line, the rest of the 

 surface about as closely but more coarsely punctured than the 

 head, in front of the posterior angles rather obscurely 

 impressed. Scutellum coriaceous with a few fine superficial 

 punctures. Elytra as broad as but a little longer than the 

 thorax, scarcely transverse, impressed at the shoulders, less 

 shining than the fore-parts, impunctate, strongly coriaceous 

 somewhat obsoletely longitudinally strigose. Abdomen with 

 the first four segments strongly coriaceous and very sparingly 

 punctured, the 5th and 6th much less coriaceous, superficially 

 and moderately closely punctured.

OSORIUS GIGANTULUS n. Sp. 



Black, shining, the sides of the thorax and posterior angles 

 reddish-translucent; apex of abdomen reddish. Head very

Allied to 0. rohustus Cam., the shape of the thorax being 

 very similar, but the sculpture of the head is entirely different. 

 Front of head bisinuate, the angles distinctly produced and 

 bluntly rounded, the front in the middle, the vertex and 

 antennal tubercles smooth, the sides of the front and the sides 

 of the vertex covered with very large superficial punctures, the 

 supra-ocular region striate, the striae widely separated, the base 

 with close, coarse, more or less transverse irregular punctures. 

 Antennae with 3rd joint much longer than •2nd, 4th to 10 ovaL 

 gradually decreasing in length. Thorax transverse, widest 

 about the middle, the anterior angles prominent, the sides 

 broadly feebly sinuate just behind, then gently rounded to
