testaceous. Head rather coareely aud moderately closely punctate, clypeo-frontal 

 suture excavated, a short frontal depression. Thorax about twice as wide as 

 long, slightly narrowed in front, sides strongly arcuate, angles prominent, disc 

 convex, closely, but simply punctate, less closely at sides, apex and base. Elytra 

 rather coarsely stiiato-punctate, striae all regular, punctures tiner toward the 

 apex. Body beneath similar in color to the upjier surface. Abdomen sparsely 

 and closely, but obsoletely punctate. Length .18 inch. ; 4 5 mm. 



The typical specimen of this s|)ecies is not now before me. It 

 seems to have had the elytral suture black. Crotch incorrectly sup- 

 pressed this species as a synonym oi' quercatum, but it is more opaque, 

 than in that species, and the striae are composed of rather coarse 

 punctures and are all regular. 



Occurs in Georgia and Texas.

 — Oblong-oval, subdepressed, dull black. Antenuse testaceous, darker externally. 

 Head sparsely punctate, with the frontal suture either excavated or not. Thorax 

 nearly twice as wide as long, angles prominent, sides strongly arcuate, disc con- 

 vex, rather densely strigoso-punctate, opaque. Elytra dull, finely alutaceous, 

 finely striato-puuctate, the striae all slightly irregular, the punctures finer or 

 obliterated at apex. Body beneath black, more shining than above ; abdomen 

 sparsely finely punctate. Length .12 — .14 inch.; 3 — 3.5 mm. 



This species varies in having the humeri and an apical .spot dull 

 red. Sometimes these spots extend and unite along the side margin. 

 Neai'ly all of these maculate specimens have a reddish head and one 

 in my cabinet has pale legs. 



A variety taken by Mr. Wenzel at Anglesea, N. J., has the elytra 

 pale, with an elongate, triangular, scutellar, piceous space, and often 

 a small lateral spot. These occur on Hazel. It is notable that all 

 the northern specimens, whether entirely black or bicolored, have 

 pale legs. Those with black legs seem to be entirely southern. 



As a synonym of this species Mr. Crotch has erroneously placed 

 puncticolle Lee. 



Occurs from Massachusetts (Blanchard) to Georgia and Florida. 



In addition to the foregoing species the following has been de- 

 scribed, but I have not been able to identify it in my material, and 

 the type is at this time not accessible to me. One specimen which I 

 obtained from Di'. LeConte as part of Crotch's typical series is cer- 

 tainly a pallidum.

Allied to M. vicinuvi [= luridnni'} in color and form, but the 

 ocular sulci meet across the front, which is evidently punctate and
