very elongate (not oblique) lateral patch, the apical joint of the antennae 

 relatively shorter, the anterior tibiae bisinuate within.

S ' Antennae long, stout, strongly serrate, joint 11 equalling 8-10 united, 

 sulcata along its inner face ; eyes extremely large, almost contiguous above and 

 beneath ; elytra with a large, oblique, dark brown velvety patch extending 

 between the striae 4-8 ; anterior tibiae feebly sinuate within ; intermediate 

 tibiae dilated, twisted, and with a narrow, pallid, opaque groove along their 

 outer face ; posterior femora with a small sharp tooth beyond the middle and 

 hollowed thence to the base ; ventral segment 5 unimpressed, truncate at the 

 tip, leaving the apical portion of the genital armature exposed.

Three males in the Fry collection agree fairly well with Maklin's 

 description. A nigro-piceous or reddish-brown, posteriorly-widened, pilose 

 insect, length 7^-S^ mm. ; the prothorax coarsely punctate and canalicu- 

 late, feebly rounded at the sides ; the elytra finely punctato-striate, the 

 interstices each with a row of somewhat closely placed minute tubercles, 

 followed b}^ a small piligerous impression ; the hairs long, fine, numerous, 

 and extending to the legs, which are coarsely punctate. Maklin does not 

 mention the small tooth on the posterior femora, or the minute tubercles 

 preceding each of the small setigerous impressions on the elytral inter- 

 stices; the identification, therefore, of his species is not absolutely certain.

c? . Elongate, rather narrow, feebly convex, widened posteriorly, shining ; 

 piceous, the femora testaceous at the base, the opaque elytral patch black ; 

 somewhat thickly clotlied, the legs included, with long, fine, bristly hairs. 

 Eyes extremely large, contiguous. Antennae long, stout, strongly serrate from 

 joint 3 onward, 11 neaily equalling 8-10, narrowly grooved within. Prothorax 

 considerably longer than broad, slightly wider than the head, moderately 

 rounded at the sides, constricted before the raised basal margin ; closely im- 

 pressed with intermixed coarse and tine punctures, canaliculate on the disc, 

 and triangularly depressed at the base. Elytra moderately long, gradually 

 widening to the middle, and there more than twice the breadth of the pro- 

 thorax ; crenato-striate, the punctures transverse, the interstices rather narrow, 

 convex, each with a series of somewhat closelj' placed setigerous impressions ; 

 the opaque lateral patch large, elongate, oblique, extending from the fourth 

 stria to near the margin. Ventral segment 6 luiimpressed, subtruncate. 

 Anterior tibiae angularly dilated towards the middle witliin, concave in their 

 basal half above, and then bowed inward and widened towards the apex, thus 

 appearing strongly bisinuate ; intermediate and posterior tibiae simple. Femora
