and eighth scarcely thicker, the obliterated epistoraal suture, ab- 

 sence of scutellum and small, broadly and extremely evenly ellip- 

 tical form, will readily serve for the identification of this distinct 

 but minute species. Two specimens. 



B. texana. n. sp. — Evenly oval, highly polished, deep black ; legs, 

 anteniise and abdomen toward tip dark rufo-testaceous ; integuments sub- 

 glabrous, the head and pronotum subimpunctate, with remote and fine, 

 decumbent and scarcely visible hairs ; elytra remotely, obsoletely punctulate 

 and similarly pubescent ; sterna impunctate, the row of punctures behind the 

 middle and posterior coxae very strong. Head small ; eyes moderate ; antennae 

 slender, not quite as long as the head and prothorax, the joints three, four 

 and six equal and four times as long as wide, five and seven longer, seven 

 and eight thicker, arcuate within, the latter three times as long as wide, joints 

 of the club rapidly increasing in length, the ninth not quite symmetrical. 

 Proihorax three-fifths wider than long, the apex scarcely more than one-third 

 as wide as the base ; basal lobe rather feeble and broadly rounded ; basal 

 angles somewhat acute. Scutellum visible, more than twice as wide as long. 

 Elytra as long as wide, three-fourths longer than the prothorax, scarcely at 

 all wider behind the base ; sutural stria deep, the lateral coarse, more or less 

 punctate, the basal fine but entire ; apex obliquely truncate, the outer angles 

 rounded. Mes-epimera long, extending almost three-fourths to the coxae ; 

 met-episterna more than three times as long as wide, the suture coarse and 

 deep, feebly and arcuately approaching very near to the elytra anteriorly ; 

 epimer a distinct. Posterior tarsi scarcely as long as the tibiae. Length 1.7 

 mm. ; width 0.95 mm.

Distinguishable at once from speculifer by its visible scutellum, 

 and from dejiexa by the same character, in addition to its much 

 smaller size and narrower form. 



B. picea, n. sp. — Rather broadly oval, dark rufo-piceous, the legs, antennae 

 and abdominal vertex rufous ; integuments subglabrous, impunctate and 

 highly polished. Head small ; eyes separated by more than their own width, 

 minutely and feebly emarginated by the antennae as usual ; epistoma long, 

 subquadrate, rather longer than wide ; antennae short, scarcely as long as the 

 head and prothorax, the third joint scarcely more than twice as long as wide 

 and only two-thirds as long as the fourth, four to six slender, subequal, seventh 

 and eighth longer and much thicker, but slightly asymmetric, the eighth only 

 slightly shorter than the seventh, eleventh more than twice as long as wide. 

 Prothorax nearly three-fourths wider than long, the apex much less than one- 

 half as wide as the base, the basal lobe well developed, rounded ; angles acute. 

 Scutellum visible, more than twice as wide as long. Elytra fully as long as 

 wide, rather more than twice as long as the prothorax, quite distinctly wider 

 at basal fourth than at base, the basal stria broadly interrupted. Mes-epimera
