Elytra in great part black, with (at most) a narrow side margin, apex, and 



slender oblique stripe yellow vittstta. Fab. 



Elytra in great part yellow, sutural black vitta besriuning at the apex but not 



reaching the base, the lateral vitta short pectita n. sp. 



From Chevrolat's description of flavovittdta it seems related rather to 

 scapularis than to vitta fa.

C insperatiis u. sp. — Totally black. Head nearly smooth. Thorax trans- 

 verse, a little wider at base than apex, sides moderately arcuate, feebly convex, 

 surface coarsely punctured, the punctures rather irregularly placed, being denser 

 along the base. Elytra a little wider than the thorax, basal marginal line not 

 angulate at the humeri, surface finely striate, striae with distant punctures, inter- 

 vals flat not closely punctate, pubescence fine and black. Prothorax beneath 

 smooth, prosternum distinctly margined. Metasternum and side pieces with very 

 coarse distant punctures, met-episterna longer than wide in front. Abdomen 

 smooth at middle, sparsely punctate at the sides, not pubescent. Length .60 inch ; 

 13 mm. 



The male has the first three joints of the anterior tarsi dilated, the 

 middle tibia not pubescent externally at tip. By the arrangement pro- 

 posed by me (Trans. Am. Ent. Soc. v. 255) this species must be referred 

 to the division A, in which the males have middle tibiae not pubescent 

 externally. By its impunctured abdomen it is more closely related to 

 tomentosus, but in its general appearance it resembles a large /)»r/(Mr?'- 

 collis. It diifers from the latter as well as from all those with a broad 

 thorax by the prosternum margined at tip. 



Occurs in Arizona.

B. caiiriuiis n. sp.— Beneath piceous, above bright green, sparsely clothed 

 with short fulvous pubescence. Antennae piceous, three basal joints pale. Head 

 shining, sparsely punctate, the vertex nearly smooth. Thorax about one-half 

 wider than long, base slightly wider than apex, sides arcuate, very slightly sinuate 

 in front of the hind angles, which are nearly rectangular, median line moderately 

 impressed, a short longitudinal impression each side in front of base, surface 

 coarsely and moderately closely punctate, especially near the base. Elytra regu- 

 larly oval, very little wider than the thorax, nearly twice as long as wide, surface 

 opaque, finely striate, intervals flat, closely submiiricately punctate. Body be- 

 neath shining, the thoracic segments coarsely punctate. Abdomen more finely 

 punctate over its entire surface. Femora piceous, tibipe and tarsi testaceous. 

 Length ..36 inch ; 9 mm. (PI. 5, fig. 3.) 



A more elongate species than B. lithophilus (PI. 5, fig. 4), which it, 

 however, resembles in general appearance. In the present species the 

 thorax is very little wider at base than the apex and the hind angles well
