Mule. — Anterior tarsi moderately strongly dilated, second and third joints 

 subequal, the latter strongly angularly emarginate in the middle of its dorsal 

 apex ; intermediate slender, scarcely perceptibly dilated ; both pairs spongiose 

 beneath ; abdomen narrowly and feebly flattened in the middle toward base, 

 the punctures rather abruptly very dense in a large median area of the basal 

 segment, and less conspicuously so on the second segment, fifth with a deep 

 rounded, impressed fovea. 



Length 3.9-4.2 mm.; width 1.6-1.8 mm. 



Texas. 



A small narrow species, allied by the formation of the sides of 

 the prothorax in the neighborhood of the basal angles, to mcestus, 

 but abundantly distinct in its narrower form, less convexity, finer 

 pronotal punctures and, especially, by the finer punctures of the 

 elytra] stria?, these not becoming' more strong-ly impressed laterally. 

 It is still more widely separated because of the notably more feeble 

 dilatation of the anterior tarsi of the male and its more slender 

 antennae. 



25 B. acq II ill is n. sp. — Elongate-oval, narrow, strongly convex, alutaceous 

 in lustre, black ; pubescence fine, rather sparse, moderate in length, dark fulvo- 

 cinereous in color and not very conspicuous. Head moderately transverse and 

 convex, somewhat finely and densely punctate, the punctures tending to coal- 

 esce longitudinally; upper lobe of eyes moderate, rounded ; epistoma broadly, 

 distinctly sinuate ; antenna? rather slender, gradually incrassate through the 

 last four joints, third not quite twice as long as the second and much shorter 

 than the next two, eleventh scarcely as wide as the tenth, the sensitive ter- 

 minal pubescence unusually fine. Prothorax about three-fifths wider than 

 long ; sides feebly convergent from base to apex, rather feebly and very evenly 

 arcuate throughout; base transverse, the lateral sinuations distinct; basal 

 angles very slightly obtuse, not prominent but not distinctly rounded ; apex 

 broadly emarginate in circular arc ; disk moderately coarsely, densely punc- 

 tate, the punctures tending slightly to coalesce longitudinally, rather sparser 

 toward the middle and decidedly finer, but denser toward the sides. Scutellum 

 moderate, ogival. Elytra about equal in width to the prothorax and between 

 two and one-half and three times longer, rather acutely and parabolically 

 rounded at apex ; sides parallel and just visibly arcuate ; disk finely striate, 

 the strise rather feebly impressed throughout the width but distinct, finely, 

 evenly and approximately punctured, the punctures distant generally by 

 about their own diameters ; intervals nearly fiat, very much more finely but 

 not very densely punctate. Abdomen rather finely and densely punctate, more 

 shining, the pubescence rather distinct. Leys well developed. 



Male. — Anterior tarsi strongly dilated, the second and third joints subequal 

 in length and width ; intermediate feebly but very distinctly dilated, with the 

 second joint rather wider than either the first or third ; both pairs with dense 

 spongiose pads beneath ; abdomen rather narrowly and strongly impressed in
