5o6 Memoirs on the Coleoptera 



stitial punctures are confused, I have probably given an incorrect 

 identification of ovata, and the name commixta given by Blatchley 

 to my ovata Lee, may be regarded as warranted. But the species 

 described by me under the name congermana, is by no means ovata, 

 as stated by the author quoted, but a distinct and vaHd species; 

 for the prothorax has a conical form, with the sides scarcely at all 

 more rounded anteriorly, and the single rows on the strial intervals 

 are composed of punctures so very fine and feeble as to be observable 

 only by careful observation and under rather high magnification, 

 and the language of LeConte quoted above would therefore not 

 apply at all. The Massachusetts type of congermana is a male, 

 and I now have a female of the species, agreeing absolutely in all 

 specific characters, from Buffalo, New York. There is now at 

 hand a specimen taken by Mr. Frost at Hopkinton, Mass., which 

 satisfies all of LeConte's description of ovata, and I therefore regard 

 it as a typical example of that species; the interstitial punctures 

 are in single rows, and, though small, are deep and distinct, and the 

 sides of the prothorax are broadly and strongly rounded anteriorly 

 and deeply constricted at the notably marked tubulation, which 

 doubtless led LeConte to regard the species as tuhulatus Say. In 

 congermana this tubulation is shorter and less conspicuous than in 

 ovata. As Mr. Blatchley states that his commixta is a name given , 

 for the Massachusetts species that I had described as ovata Lee, 

 I regard this specimen described by me as properly the type of 

 commixta; it is represented in my collection also from Virginia and 

 the mountains of western North Carolina. 



The following is another species allied to congermana, in having a 

 subconical prothorax: 



Stethobaris convergens n. sp. — Stout and very convex, polished, deep 

 black throughout and glabrous; beak in the female thick, evenly and 

 moderately arcuate, shining, though rather strongly, sparsely sculptured 

 and much longer than the head and prothorax, the antennae at the 

 middle; prothorax one-half wider than long, the sides strongly converging, 

 almost evenly and moderately arcuate from base to the apical con- 

 striction, which is tubulate and slightly less than half as wide as the 

 base; punctures strong, separated by about their own diameters, smaller 

 and closer toward the well defined median smooth line, which is entire as 

 usual, close but not in mutual contact on the propleura; basal lobe 

 moderate but rather abrupt and distinct; scutellum small, quadrate, 

 impressed along the middle; elytra large, a fourth longer than wide, 

 very obtusely parabolic, with distinct though obtuse humeral promi-
