surface, especially of the abdomen, duller, and the punctuation of 

 the elytral strite and intervals very diflferent. I have only seen 

 the female. 



It is interesting- to note that the hairs growing from the punc- 

 tures of the elytral striae, which are usually extremely minute, here 

 become quite long and distinct ; this may possibly be dependent in 

 some way upon the slight difference between these punctures and 

 those of the intervals observable in this species. 



31 B. interillixtlis n. S]). — Oblong-oval, rather depressed, dark reddish- 

 brown throughout, but very feebly shining, somewhat densely clothed with 

 moderately long robust stitf and subrecumbent pubescence, which is pale 

 golden-yellow and dark jiiceous-brown coufiisedly intermingled, the pale hairs 

 slightly the longer and broader. Head moderate, about one-half wider than 

 long, feebly convex, somewhat coarsely and rather densely punctate, the inter- 

 spaces comjjletely dull but not definitely sculptured ; upper lobe of the eyes 

 large, nearly circular ; antennae ratlier robust, nearly as long as tlie head and 

 prothorax, gradually, strongly incrassate toward apex, second joint about one- 

 half as long as the third, three to five uniformly and very rapidly decreasing 

 in length. Prothorax about three-fourths wider than long ; sides in basal 

 two-thirds parallel, strongly arcuate, thence more strongly convergent and 

 straighter to the rather prominent apical angles ; apex broadly emarginate in 

 circular arc ; base transverse, the lateral sinuations strong ; disk broadly, 

 evenly, moderately convex, somewhat coarsely, deeply, evenly and very 

 densely punctate, the interspaces strongly reticulate and slightly shining 

 toward the middle, absolutely dull laterally. Scutellum punctate, the margin 

 broadly impunctate and polished. Elytra about three-fourths longer than 

 wide, three times as long as the prothorax and subequal to it in width ; sides 

 parallel, very feebly arcuate posteriorly ; disk not very finely striate, the 

 striae somewhat abrujDtly but moderately impressed, rather finely and closely 

 punctate, the punctures separated by scarcely more than their own diameters 

 throughout the width, the striae more strongly impressed externally ; intervals 

 flat, not densely, very minutely punctate, slightly shining. Abdomen strongly 

 shining, finely, evenly and not very sparsely punctate ; pubescence fine, 

 moderate in length, not dense but pale fulvous-yellow and quite distinct. 

 Legs moderate. 



Male. — Anterior tarsi very feebly dilated, the middle slightly robust ; both 

 coarsely, rather sparsely squamulose beneath ; abdomen slightly and narrowly 

 flattened in the middle toward base. 



Length 5.0-6.0 mm. ; width 2.0-2.6 mm. 



Arizona (Wiuslow). Mr. "Wickham. 



The anterior tarsi of the female are robust or subdilated, not 

 differing appreciably from the male, but are devoid of squamules 

 beneath ; in both sexes all the tarsi are clothed with very short
