little longer. As it is precisely similar to the normal forms in 

 every other particular, I am inclined to regard it as an accidental 

 variation. 



M. foveata Lee— N. Spec. Col., 1866, p. 140.— Elongate, suboval, 

 polished, moderately convex, piceous-black throughout, the legs and antenna? 

 flavate ; elytra sometimes testaceous throughout, but normally black, with a 

 small suffused subhumeral reddish spot ; pubescence short, fine, extremely 

 sparse, dark and inconspicuous. Head shborbicular, feebly, evenly convex, 

 finely, sparsely punctate ; eyes very small, not prominent, separated by nearly 

 four times their width ; antennae somewhat robust, not attenuate, scarcely 

 two-fifths as long as the body, the intermediate joints strongly obconical, 

 about one-half longer than wide, third quite distinctly longer than the fourth. 

 Prothorax nearly one-half wider than the head, two-fifths wider than long, 

 the apex subtruncate, three-fourths as wide as the base, the latter transverse 

 and straight ; sides strongly rounded at the middle, thence strongly conver- 

 gent and feebly arcuate to the apex, and distinctly convergent and broadly 

 sinuate to the basal angles, which are right and not at all rounded ; disk 

 strongly declivous toward the apical angles, finely but deeply, distinctly, 

 sparsely punctate, narrowly, feebly impressed in the middle toward base ; 

 basal fovese rounded, moderate in size, very deep and distinct. Elytra a little 

 more than three times as long as the prothorax ; sides feebly arcuate ; disk 

 slightly wider behind the middle, at base a little wider than the pronotal 

 disk, the humeri distinctly exposed, narrowly rounded ; surface with feebly 

 impressed series of rather coarse, moderately close punctures, the intervals 

 each with a single series of very fine punctures. Abdomen very finely sparsely 

 punctate ; anterior portions more coarsely but sparsely so. Legs moderately 

 slender, normal. Length 5.0-5.8 mm.; width 1.8-2.2 mm. 



Michigan ; Iowa ; Indiana. 



The sinuation of the sides of the prothorax is not always so 

 apparent as in the type, these often being convergent and straight 

 from near the middle to the base ; it is more apparent in the large 

 specimens, and may therefore be more especially a female charac- 

 teristic. Otherwise there does not appear to be any noteworthy 

 sexual difference. 



M. gilvipes n. sp. — Moderately robust and convex, suboval, polished, 

 black ; under surface dark rufo- testaceous, the legs flavate ; antennae piceous- 

 black, paler toward base ; each elytron with a large, clearly limited, oblique 

 basal spot, extending to internal third of the width ; pubescence rather long 

 and erect, but dark, sparse and inconspicuous. Head feebly convex, rather 

 coarsely but sparsely and feebly punctate ; eyes rather small, separated by 

 scarcely three times their width ; antennae robust, the joints strongly obconi- 

 cal, generally about one-half longer than wide, the third much longer than the 

 fourth. Prothorax about one-third wider than long, the apex feebly arcuate,
