California (Truckee, Nevada Co. )• 



The three specimens before nie indicate a species allied to pul- 

 veridentus, but quite distinct in its more depressed parallel form, 

 similarity in size and form of the male and female, and more 

 decidedly in the form of the hind wings. The wings are about one- 

 fourth longer than the prothorax and one-half as long as the elytra, 

 consisting of a long parallel very slender fillet, subhyaline in struc- 

 ture, about four times as long as wide, with the two veins very 

 feebly developed, not extending quite to the middle and equally tri- 

 secting the width throughout their extent. 



30 B. aiiripilis Horn.— Trans. Am. Phil. Soc, XIV, p. 3.53.— Oblong- 

 oval, very convex ; sides parallel ; integuments dull, dark brown in color ; 

 pubescence moderate in length, recumbent, rather robust and dense, bright 

 golden-yellow and blackish-piceous confusedly intermingled, the two kinds 

 subequal in size and abundance. Head moderate, strongly transverse ; sides 

 strongly convergent anteriorly from before the eyes, the apex strongly sinuate ; 

 surface feebly convex, very densely punctate, the punctures coarse posteriorly, 

 liner anteriorly ; interspaces rather shining, convex, very minutely, evenly 

 reticulate ; eyes moderate ; antenna rather short and slender, gradually and 

 not very strongly incrassate toward ajjex, second joint not one-half as long as 

 the third, the latter rather elongate although distinctly shorter than the next 

 two combined. Prothorax feebly narrowed from base to apex, three-fourths 

 wider than long ; sides slightly more strongly arcuate before the middle ; apex 

 broadly etnarginate ; base transverse, the lateral sinuations broad and distinct : 

 disk very strongly convex, not very coarsely but deeply evenly and very 

 densely punctate throughout, the punctures nearly in mutual contact laterally, 

 but not coalescent ; interspaces convex, alutaceous, very minutely, evenly 

 granulato-reticulate. Scutellum punctate, alutaceous, strongly granulato- 

 reticulate throughout. Eliftra but slightly more than one-half longer than 

 wide, equal in M'idtli to and nearly three times as long as the prothorax ; sides 

 parallel and nearly straight ; apex rather obtusely rounded ; disk not very 

 finely but feebly and indistinctly striate, the stride very finely feebly and not 

 very approximately punctate, the punctures distant by from three to four 

 times their own diameters toward tlie suture, not much exceeding in size those 

 of the intervals and not at all distinct ; intervals feebly convex, strongly 

 granulato reticulate, rather coarsely and densely punctate. Abdomen rather 

 dull, finely, rather densely punctate and somewhat densely covered with 

 rather long, dense, robust, bright yellow hairs which are very conspicuous. 



Length 6.2 mm. ; width 2.8 mm.

This species is related to intermixtus in the dual character of the 

 vestiture of the upper surface, Init not otherwise to any extent ; it 

 is rather larger and decidedly more convex, with smaller eyes, the
