and yellowish pubescence, giving the surface a mottled appearance, 

 the pubescence with a greenish tinge in certain lights. Scutellum 

 broadly triangular, and broadly rounded at apex. 



Elytra four times as long as pronotum, and slightly wider than 

 pronotum at middle ; humeri strongly developed and elevated ; sides 

 nearly parallel from base to apical third, then strongly, arcuately 

 narrowed to the tips, which are separately, narrowly, obliquely 

 truncate; disk uneven, broadly, feebly depressed at basal third, with 

 numerous irregularly distributed tubercles, those on the basal 

 regions more strongly developed; surface coarsely, rather densely, 

 irregularly punctate, the punctures becoming finer and more obso- 

 lete toward the apices, rather densely clothed with short, recumbent, 

 pale yellow pubescence, variegated with brownish pubescence, but 

 not forming distinct designs, except for an obsolete, narrow, trans- 

 verse, zigzag, white fascia on each elytron behind the middle, and 

 the tubercles clothed with dark brown hairs. 



Abdomen beneath feebly, finely, densely punctate, and rather 

 densely clothed with short, recumbent, whitish pubescence; last seg- 

 ment elongate, strongly attenuate posteriorly, and arcuately emargi- 

 nate at apex. Prosternum feebly, arcuately elevated between the 

 coxae; prosternal process about two-thirds as wide as the coxal 

 cavities. Legs mottled with short, recumbent, whitish pubescence; 

 femora feebly arcuate, and strongly, abruptly clavate toward the 

 apices ; tibiae subcylindrical. 



Length, 8 mm. ; width, 3.6 mm.

 crhtatvs Fisher, but it differs from that species in having the tips 

 of the elytra obliquely truncate, without a basal crest on each elytron, 

 and by the different pubescent markings. 



LEIOPUS INFUSCATUS, new species 



Elongate, subparallel, and rather strongly flattened above, uni- 

 formly brownish yellow, densely clothed with brownish- white, scale- 

 like pubescence, and ornamented with dark-brown pubescent mark- 

 ings; mandibles reddish, with the tips black; palpi brown, with the

Head quadrate in front of antennal tubercles, subequal in width at 

 top and bottom, feebly convex, rather deeply, triangularly depressed 

 between the antennal tubercles, which are rather widely separated 

 and strongly elevated, finely, densely punctate, densely clothed with 

 short, recumbent, brownish and whitish pubescence, giving the sur-
