180 AMERICAN COLEOPTERA. 



sociated it, but the latter species is still more feebly mottled, 

 never in my experience with a conspicuous pale line on the 

 third interspace, the antenna? pale at base and more slender, 

 with at least the first six joints as long as or longer than 

 wide. The hind femora in pulloides are armed with a small 

 acute tooth and two very small denticles. 



B. pullus n. sp. 



Form and size of pauperculus , aureolus and mixtus ; pubescence not 

 very dense, cinereous mottled with brownish-ochreous. Prothorax 

 with four discal brownish spots which are often obscurely defined. 

 The most conspicuous markings on the elytra consist of a pale line at 

 the middle of the third interspace, before, behind and external to which 

 are oblong brownish spots, the latter transverse. Antennae passing 

 the humeri, stout, black, basal three or four joints pale; joints 2 and 

 3 a little longer than wide, 4 as wide as long, 5 distinctly transverse, 

 5-8 gradually wider, 8-10 equal, nearly one-half wider than long. 

 Head alutaceous, finely punctate, eyes moderately prominent, separated 

 by a little less than their own width ; front not distinctly carinate, the 

 median line, however, a little prominent in certain lights. Prothorax 

 wider than long, sides feebly sinuate and divergent behind, surface 

 coarsely but not densely punctate. Elytra about one-fifth longer than 

 wide, sides broadly arcuate and a little divergent behind ; striae fine, 

 intervals flat, polished, with fine punctures which tend to form rather 

 feeble transverse rugae. Pygidium oblique basally, convex and vertical 

 in apical half, the tip a little inflexed, pubescence mottled, brown and 

 cinereous, punctuation fine, subrugose. Legs sometimes entirely pice- 

 ous, more often with the thighs testaceous at apex, and all the tibiae 

 testaceous in apical half or more. Hind thighs with a small acute 

 tooth and two denticles which maybe quite distinct or nearly obsolete. 

 Hind tibiae very feebly carinate on the outer face, the terminal spur 

 slender and about one-fourth the length of the first tarsal joint. 

 Length, 1.5-1.9 mm. ; width, .8-. 9 mm. 



California; Ojai (type), San Diego, Catalina Island. 



Closely allied to mixtus apparently, the latter differing in 

 having the vestiture predominantly ochraceous and just per- 

 ceptibly mottled, the legs pale rufous, except the base of the 

 hind femora. Pauperculus is more obscurely mottled, and 

 has more slender antennae, and the terminal spur of the hind 

 tibiae is about twice as long. 



B. inquisitus n. sp. 



Elongate oval, piceous black, basal four joints of antennas pale, legs 

 bicolored, the front and middle femora in less, and the hind femora in 

 more than basal half, piceous; the tibiae pale; terminal joint of front
