series rather uneven in their course, the intervals varying in width. Under 

 surface, legs and coxae nearly as in lugubris. Length 6.8-7.6 mm. ; width 

 2.8-3.0 mm. 



New Jersey ; Michigan. 



This species is closely allied to lugubris, but may be distinguished 

 by its slightly smaller eyes, the unexplanate sides of the prothorax, 

 and more feebly impressed, less conspicuously punctured and more 

 uneven elytral striae, as well as by its rather larger size and more 

 robust form. 



One specimen before me, from New York, is black above and 

 piceous-black throughout beneath, and, as I notice a few other 

 slight differences, it may possibly indicate a variety. 



The maxillary palpi are rather shorter and thicker than in lugu- 

 bris, the recti-triangular fourth joint being but slightly longer than 

 wide. 



M. lugubris Lee. — Proc. Am. Phil. Soc, XVII, p. 618. — Elongate-oval, 

 rather convex, piceous-hlack ; under surface throughout paler, hrown ; legs 

 and antennae still paler, more flavate ; polished, the pubescence very fine, 

 semi-erect, short, moderately dense hut nearly of the same color as the body 

 and not conspicuous. Head feebly convex, coarsely, deeply, rather densely 

 punctate ; eyes moderate, separated by abdut twice their width ; antennae 

 moderately robust, scarcely two-fifths as long as the body, feebly attenuate 

 toward apex, joints obconical, in the male nearly twice as long as wide, a 

 little shorter in the female, third and fourth equal. Prothorax two-thirds 

 wider than long ; apex truncate or very feebly sinuate, two- thirds as wide 

 as the base, the latter transverse and straight ; sides broadly, almost evenly 

 rounded throughout, more convergent toward apex ; basal angles obtuse and 

 very narrowly rounded ; disk distinctly explanate from just before the middle, 

 more broadly around the basal angles, and thence gradually more narrowly 

 along the base, rather coarsely, deeply, somewhat unevenly and densely punc- 

 tate, the punctures separated by about their own widths ; broadly, feebly 

 impressed in the middle toward base, the basal foveae extremely feeble and 

 indefinite. Elytra nearly four times as long as the prothorax, and, behind 

 the middle, two-fifths wider, rather abruptly and obtusely rounded behind, at 

 the humeri just visibly wider than the disk of the pronotum, the humeri not 

 exposed ; sides broadly arcuate, especially behind ; disk with rather deeply 

 impressed regular series of rather small but deep close- set punctures, the 

 intervals convex, finely, confusedly and somewhat closely punctate. Under 

 surface finely, sparsely punctate, a little more coarsely so anteriorly. Legs 

 slender, normal. Length 6.4-7.0 mm. ; width 2.3-2.9 mm. 



New York ; Kansas. 



The anterior coxae are large, very prominent and approximate, 

 globulo-conoidal, the cavities separated by a thin lamina which is
