470 Coleopterological Notices, V. 



Color paler, dark piceous to rafous, the elytra always brighter and rufescent. 



Pygidium broadly, very feebly and evenly convex, similar in the sexes 



but a little shorter and broader in the female ; elytra shorter, the 



humeri obsolete and the sides more oblique OCCidUlIS 



Pygidium differing in the sexes, in the female strongly tumid, in the male 



nearly flat and unmodified. 



Pygidial tumor of the female very large, compressed, broadly rounded 



in profile; body more robust (aculeatus Lee, i. litt.)...allliO]]iclIS 



Pygidial tumor abrupt, acutely rounded in profile, the highest point 



being at the lower margin, the surface thence broadly concave to the 



upper margin (var. mendoc'mo and speculum Csy.) zeptiyrillllS 



Elytra strongly though sparsely punctate ; head longitudinally carinate above 

 the eyes ; pygidial characters probably common to both sexes ; ventral 

 excavation of the male small. 

 Ambient sulcus of the head continued to the base ; pronotum with a com- 

 plex process at each side of the median subbasal fovea. ..cicatricosus 

 Ambient sulcus not continued posteriorly beyond the fovese ; pronotum with 

 a simple erect spiculate elevation at each side of the median fovea. 

 Pygidium of the male small, transverse, broadly tumid, with a transverse 

 polished and impunctate excavation along its lower margin. 



pygidialis 



Pygidium in both sexes with an abrupt, strongly elevated, compressed 



and cariniform tooth at the middle denticauda 



In these species the anterior femora, apparently in both sexes, 

 have an elongate narrow area on the under surface which is strongly 

 and transversely punctato-rugose. 



B. pyi^idialis n. sp. — Moderately slender, polished, bright rufo-testa- 

 ceous throughout, the abdomen rather darker ; legs pale, with the knees 

 darker ; pubescence rather long, coarse, very sparse. Head as long as wide, 

 subequal in width to the prothorax ; eyes moderate, very convex, scarcely be- 

 hind the middle, outline behind them almost evenly, semi-circularly rounded ; 

 nude fovese deep, connected by a distinct sulcus ; vertex impunctate, finely 

 carinate at the base of the occiput ; surface outside of the supra-ocular carinse 

 finely sparsely and subasperately punctate; antennse a little longer than the 

 head and prothorax, moderately stout, the basal joint emarginate above at 

 apex and impressed on the surface behind the emargination, second very much 

 smaller and narrower than the first, equal to the second and but slightly 

 longer than wide, two to eight subequal, ninth but very slightly longer than 

 the eighth, tenth trapezoidal, foveate within, eleventh stouter with an ante- 

 riorly oblique spiculate tooth near the base. Prothorax not longer than wide, 

 widest and broadly rounded before the middle, impunctate, the lateral sulci 

 broadly impressed, median narrow, vanishing beyond the middle ; three sub- 

 basal foveae moderate, connected by an extremely feeble biarcuate groove, the 

 lateral each with an erect spicule immediately behind it ; spicule at the sides 

 of the median fovea small, erect and simple ; surface between the median
