COLEOPTERA. 147 



long, finely and obscurely reticulate, each having at base a fine but very 

 distinct asperate puncture. First abdominal segment much narrower than 

 the contiguous elytra ; surface more finely and densely punctat<^ than the 

 elytra, feebly shining through the very dense coarse pubescence, having 

 along the sides a few rather small erect black setae. Legs moderate ; coxae 

 and femora dark reddish-brown ; tibiae and tarsi distinctly paler, reddish- 

 testaceous ; spinules of the fimbriate row along the outer edge of the anterior 

 tibiae short, equal, contiguous and very pale in color ; anterior tarsi strongly 

 dilated toward base, densely pubescent beneath ; middle tibiae slender, 

 fimbriate at tip with short equal pale spinules, als,o having a rather long 

 terminal spine and a second much shorter one, having at the middle of its 

 length two small oblique inner and two outer spines, also at one-third the 

 length from the apex two inner and one or two similar outer spines. Under 

 surface of the body dark piceous -brown. Length (contracted) 2.3 mm.

The description is taken from a male while that of occnltus is 

 drawn from the female ; the differences noted in the shape of the 

 pronotnm, together with the structure of the middle tibiae are too 

 great to be accounted for by sex, although it may be possible that the 

 lateral spines alluded to are not altogether constant. It appears to 

 belong near pubescens in the tables. 



C setifer n. sp. — Form rather slender, very convex. Color of head and 

 prothorax black, basal margin of the latter paler ; elytra dark piceous-black, 

 paler and reddish at the base, especially near the middle of each, also nar- 

 rowly paler at the apices ; abdomen reddish-fuscous ; pubescence very fine 

 and moderately dense, very short and recumbent, cinereous. Head rather 

 small, convex, polished, very sparsely pubescent; eyes very coarsely reti- 

 culated ; antennae not as long as the head and prothorax together, very 

 strongly compressed toward tip, basal joints dark piceo-testaceous, paler 

 toward tip, joints two to seven nearly piceous-black, basal joint sub-cylin- 

 drical, about two and one-half times as long as wide, second thinner, nearly 

 cylindrical, scarcely two-thirds as long as the first, three-fourths as long as 

 the third which is thinner and narrowed toward base, third and fourth 

 equal, fifth equal in length, slightly thicker and less strongly narrowed 

 toward base, nearly three times as long as wide, joints six to ten slightly 

 shorter, equal in length, increasing in width, the former nearly one-half 

 longer than wide, the latter about as wide as long, eleventh about one-half 

 longer than wide, oval, obliquely and rather obtusely acuminate at tip. 

 Prothorax about one-third wider than long; sides very evenly and almost 

 circularly arcuate throughout, nearly parallel for a short distance from the 

 base ; apex broadly arcuate, nearly three-fifths as long as the base which is 

 broadly and very feebly arcuate ; basal angles from above slightly obtuse 

 and not rounded, viewed laterally they are obtuse and narrowly rounded ; 

 disk very convex, highly polished, impuuctate except the scars left by fallen 

 hairs. Elytra at base slightly narrower than the pronotuni ; sides slightly 

 convergent posteriorly, feebly arcuate near the humeri, nearly straight
