has tlie usual small spot of pale scales before the middle of the 

 disk, but otherwise there is scarcely any resemblance to geminatus. 

 Numerous specimens.

The form described below is remarkable in having angulate 

 prominences behind the humeri, which may be homologous with 

 the corresponding protuberances in Plectroraodes. 



1.. scapillaris n. sp. — Parallel and sonunvhat stout, moderately convex, 

 black, densely clothed throughout with brown scales nearly uniform in color, on 

 the pronotum slightly larger Init not obscuring the punctures and slightly i)aler 

 in a feeble obli((ue line at each side and in the middle toward base. Head a 

 little less than one-half as wide as the prothorax, densely fulvo-squamulose, 

 the eyes separated by nearly four times their own width ; beak long, about as 

 long as the head and prothorax, straight, bent downward and gradually dilated 

 toward tip, tricarinate above, squamose and densely punctato-rugose through- 

 out; antenn:e long and slender, inserted near the apex, the scrobes long, deep, 

 coarse, straight and horizontal, scape very long, slender, feebly enlarged dis- 

 tally, second joint of the funicle greatly elongate, more than twice as long as 

 the first and almost as long as the next four combined. Prothorax two-lifths 

 ■wider than long, the sides subparallel, consi)icuously and almost evenly arcu- 

 ate, a little more convergent toward apex than base, the former three-fourtlis 

 as wide as the latter, truncate, the ocular lobes well developed ; base broadly 

 arcuate; disk sparsely, moderately coarsely punctate, each puncture bearing a 

 small stiff hair. Scutellum circular, densely clothed with ixile whitish scales. 

 Elytra three-fifths longer than wide, between three and four times as long as 

 the prothorax and nearly one-half wider; sides parallel and straight behind 

 the post-humeral projection, outwardly obliciue and straight from the base to 

 the apex of the angulate prominence, gradually rounded in about apic;il third, 

 the subapicid umbones Avell marked; disk finely striate, the stria- finely, 

 feebly and indistinctly punctate; intervals Hat, finely, sparsely punctate, each 

 puncture bearing a small stout hair. .4 Mowfn densely squamose on the two 

 basal segments, thence coarsely pubescent with squamose sublateral areas 

 to the apex; legs long, densely squamose and with short stiff sparse hairs, 

 the scales paler toward the femoral apices. Length 12.0 mm. ; width 5.0 mm. 

 (across the post-humeral angular prominences 5.5 mm.).

This large and distinct species may be placed near callosus 

 Lee, for the present, but is not closely allied to any other thus 

 far described. The type is probably a female. Two specimens. 



L.. te!«sellatus n. sp. — Elongate-oval, strongly convex, black, the tibiic, 

 tarsi and antennte rufo-piceous; scales very dense, rounded and with radiating 

 strigosity, only slightly larger on the pronotum but more distinct, cinereous-
