66 Coleopterological Notices. 



B. Iionestus n. sp. — Slightly robust, subparallel, black ; elytra, legs 

 and antenna? thronghout testaceous, the first very broadly and indefinitely 

 clouded toward the suture ; head and pronotum strongly shining, rather 

 coarsely and strongly reticulate ; abdomen reticiilate, polished, the retal lines 

 fine throughout. Head rather convex, slightly narrower than the prothorax, 

 not tuberculate ; median fovea very small and feeble, shining, with a few 

 rather large and distinct widely-dispersed punctures ; antennal tuberculations 

 moderate, smooth ; suture very fine but distinct ; antennjB rather slender ; 

 second joint quite robust, nearly as long as the next two, third scarcely one- 

 half longer than the fourth, fourth and fifth subequal, sixth slightly shorter, 

 feebly transverse, six to ten very evenly but rapidly wider, the tenth nearly 

 one-half wider than long, eleventh slightly shorter than the two preceding. 

 Prothorax as wide as the base of the elytra, one-third wider than long ; sides 

 in anterior two-thirds parallel and nearly straight, then convergent and feebly 

 arcuate, feebly sinuate for a short distance before the basal angles, which are 

 very obtuse, slightly rounded and not distinctly prominent ; lateral angles 

 very broadly rounded and not distinct, apical right, very narrowly rounded ; 

 apex two-fifths wider than the base, just visibly arcuate, the latter truncate ; 

 disk not very coarsely punctate, the punctures very deep and distinctly defined, 

 sparsely and somewhat unevenly distributed ; pubescence fine, sparse and 

 inconspicuous, the median groove rather coarse, deep and distinct. Elytra 

 scarcely as long as wide, just visibly wider and about two-fifths longer than 

 the prothorax ; sides feebly divergent, nearly straight ; surface feebly im- 

 pressed near the base and suture, rather finely and not very densely punctate, 

 the punctures separated by about twice their own diameters ; pubescence 

 moderate in length, fine, rather s^jarse. Abdomen just visibly narrower than 

 the elytra, rather more coarsely and densely punctate than usual, beneath 

 rufo-piceous, slightly more densely but rather finely punctate. Length 3.3 mm.

The hypomera are narrow, distinctly less than one-half as wide 

 as the intervening- coxal distance, and are strongly and narrowly 

 concave throughout the length, the sutures almost completely obso- 

 lete, the coxal fissures rather long, widely open, the prosternal sur- 

 face immediately before them transverseh^ impressed. The mentum 

 is shining, coarsely reticulate and broadly, strongly impressed in 

 the middle toward base, the hypoglottis membranous, and nearly 

 one-fourth as long as the entire mentum. 



The prosternal sutures being effaced, with the coxal fissures 

 widely open, constitute of this very distinct species, one of the 

 bonds uniting the cordatus and annularis groups of LeConte. 

 Although the sutures are obsolete, it is easy to perceive the extent 

 of the hypomera, as the reticulation of the surface is longitudinal 

 on these parts, and without definite arrangement elsewhere.
