Rhode Island. 



The hypomera are very wide, with the sides parallel, flat but 

 depressed far below the lateral edges, so that the latter are very 

 acute and prominent ; the coxal fissures are extremely short and 

 appear to be very narrowly open, the hypomeral edge being be- 

 neath the prosternal or anterior edge. The mentum is nearly flat, 

 the subbasal median impression being somewhat feeble. 



This species belongs in the neighborhood of basalis, but difi"ers in 

 the form of the prothorax and sinuation of the convergent portion 

 of the sides, and in its rather distinct basal angles ; the elytra are 

 more finely and densely punctate and the size considerably larger. 



B. turlbllleiltlis n. sp. — Rather slender, black ; elytra very pale, yel- 

 lowish-white, the basal margin piceous-black ; legs and antennse testaceous, 

 the femora darker ; integuments polished, head and prothorax finely, evenly 

 and rather strongly reticulate ; abdomen coarsely reticulate, with the retal 

 lines very fine. Head distinctly narrower than the prothorax, convex ; eyes 

 rather large and prominent ; surface finely, rather feebly and sparsely punc- 

 tate, neither foveate nor tuberculate ; antennal prominences small and very 

 feeble ; suture fine, not impressed ; epistoma with a fine apical tubercle near 

 each anterior angle ; anteon?e rather slender, evenly incrassate ; second joint 

 not very robust, cylindrical, slightly longer than the next two together, fifth 

 distinctly longer than wide, eighth and ninth similar in form, the latter the 

 larger, just visibly wider than long, tenth slightly shorter than the ninth, less 

 than one-half wider than long, eleventh not quite as wide as the tenth, dis- 

 tinctly elongate, gradually pointed, as long as the seventh and eighth together. 

 Prothorax nearly as wide as the base of the elytra, two-fifths wider than long ; 

 sides in anterior two-thirds parallel and straight, then convergent and very 

 feebly arcuate to the basal angles, which are very obtuse and broadly rounded 

 and not distinct ; lateral angles very obtuse and broadly rounded, ajMcal right, 

 not visibly rounded and just perceptibly anteriorly prominent ; apex trans- 

 versely truncate; base very feebly .arcuate ; disk trans vei'sely, moderately 

 convex, finely punctate, the punctures rather feebly impressed and somewhat 

 dense, being separated by scarcely more than twice their own diameters ; 

 median groove very fine, feebly impressed, not attaining the apex. Elijtra 

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

 nearly straight, just visibly divergent ; outer angles rather broadly, inner 

 very narrowly rounded; sirrface feebly impressed near the suture at base, 

 finely, feebly and densely punctate. Abdomen distinctly narrower than the 

 elytra, as wide as the prothorax : sides parallel and nearly straight, the sixth
