132 Coleopterological Notices, III. 



three-fourths as wide as the base, the latter straiglit ; sides broadly rounded, 

 convergent and straight, or very feebly sinuate, from behind the middle to 

 the base, the angles rather distinctly obtuse but not at all rounded; disk 

 distinctly impressed in the middle toward base, rather coarsely, deeply and 

 sparsely punctate, the basal fovefe small, deep and conspicuous. Elytra a 

 little less than three times as long as the prothorax, and, behind the middle, 

 about two-fifths wider; base slightly wider than the disk of the latter, the 

 humeri distinctly exposed ; sides feebly arcuate behind, gradually and acutely 

 rounded at apex ; disk punctured and impressed nearly as in foceata. Under 

 surface very sjjarsely punctate, the abdomen minutely so. Legs rather short. 

 Length 4.7 mm. ; width 1.8 mm. 



North Carolina. 



The single specimen serving as the basis of the above description, 

 represents a species closely allied to foveata, but distinguishable 

 by its distinctly shorter broader elytra, smaller size, longer and 

 more erect pubescence, slightly larger and more approximate eyes, 

 blackish antennae, much larger, more abruptly defined basal spots of 

 the eh'tra, and slightly coarser punctuation. 



M. nigerrillia n. sp. — Oblong, parallel, moderately convex, highly 

 polished, intense black throughout above; legs and under surface piceous- 

 black, the tarsi paler ; antennae pale brownish-testaceous throughout ; pubes- 

 cence fine, short, dark, very sparse and inconspicuous. Head feebly, evenly 

 convex, finely, very sparsely punctate ; eyes rather small, separated by nearly 

 three times their width ; antennse rather robust, barely more than one-third 

 as long as the body, scarcely attenuate toward apex, the intermediate joints 

 obconical, with the sides rounded, not quite one-half longer than wide, third 

 and fourth equal. Prothorax four-fifths wider than long, the apex broadly 

 arcuate, two-thirds as wide as the base, the latter transverse, with a small 

 feeble sinuations at each side of the middle ; sides broadly arcuate through- 

 out, more convergent toward apex ; basal angles obtuse and very narrowly 

 rounded ; disk extremely minutely, sparsely punctate, barely perceptibly 

 impressed in the middle toward base, the basal fovese broadly impressed and 

 indefinite, but each ajiparently having a very small foveiform puncture in the 

 middle. Elytra a little more than three times as long as the prothorax, and, 

 at the middle, scarcely visibly wider than the disk of the latter, gradually, 

 not very acutely rounded at apex ; sides parallel and feebly arcuate ; humeri 

 not exposed ; disk finely, sparsely punctate, without series, the impressed 

 lines very feeble, but visible by obliquely reflected light, almost throughout the 

 width, the punctures aggregated in wide longitudinal lines, with more sparsely 

 punctate intervals. Under surface finely, sparsely punctate. Legs normal, tlie 

 posterior tarsi much shorter than the tibise. Length 5.3 mm. ; width 2.0 mm. 



New York. 



The single specimen representing this species is related to fra- 

 terna, but is immediately distinguishable by the complete absence
