from base to apex and very feebly arcuate, very minutely and sparsely punc- 

 tate, beneath minutely, very sparsely punctate, the pubescence longer and 

 more distinct. Length 1.8 mm. 



Texas (Galv^eston). 



The hypomera are feebly impressed along the sides and are rather 

 wide, the sutures obliterated, the coxal fissures short, almost com- 

 pletely closed. The mentum is short, fully twice as wide as long, 

 broadly, feebly emarginate at apex throughout the width, deeply 

 and coarsel}^ foveate in the middle near the base, the surface dis- 

 tinctly tumid on either side of the fovea, and having a few coarse 

 setigerous punctures. 



Although to be classed with basalts, this little species, one of the 

 smallest known in our fauna, is not very closely allied to it. The 

 el3'tra are relatively larger and longer, and are much more finely 

 punctate. The sides of the prothorax are straight in apical three- 

 fourths, while in hasalis the parallel portion of the sides is much 

 shorter. The series before me exhibits great variation in the extent 

 of the brownish-piceous tint, this being confined in one specimen to 

 the basal margin.

B. neglectus n. sp. — Slender, black ; elytra very thin and translucent, 

 whitish, the suture and base blackish ; legs and antennae testaceous, the latter, 

 infuscate, the femora darker ; head and pronotum very finely, densely and 

 evenly granulato-reticulate, rather feebly shining ; abdomen polished, coarsely 

 reticulate, the lines fine. Head much narrower than the prothorax, convex, 

 neither foveate nor tuberculate, finely, rather feebly and sparsely punctate, 

 the median portions impunctate ; antennal prominences very small and feeble ; 

 eyes moderate ; epistomal suture fine ; epistoma with a fine distinct tubercle 

 on the apical edge near each anterior angle ; antennse moderate, rather strongly 

 compressed, gradually and strongly incrassate ; second joint slightly longer 

 than the next two together, fifth quadrate, rather longer than either the foui'th 

 or sixth, six to ten wider than long, the latter by three-fourths its length, 

 eleventh very slightly wider than long, very obtuse ; joints throughout not very 

 compactly joined. Prothorax nearly as wide as the base of the elytra, two-fifths 

 wider than long ; sides in anterior three-fourths parallel and straight, then 

 very strongly convergent and broadly, feebly but distinctly sinuate to the 

 basal angles, which are obtuse and rounded but rather distinct, lateral more 

 broadly rounded and less distinct, apical right, very narrowly rounded, not at 

 all prominent ; base and apex transversely truncate ; disk transversely, mode- 

 rately convex, rather finely, feebly and densely punctate ; punctures separated 

 by nearly twice their own widths ; median groove very fine but distinct. Elytra 

 quadrate, two-thirds longer and one-third wider than the prothorax ; sides 

 nearly straight, feebly divergent ; surface distinctly impressed near the suture 

 at base, finely, rather feebly and densely punctate ; pubescence extremely
