testaceous with sides piceoiis. Antennae pale. Head sparsely punctate, clypeus 

 more coarsely and closely, a slight frontal impression, clypeo-frontal suture 

 sinuous, sometimes indistinct. Thorax nearly, twice as' wide as long, scarcely 

 narrowed in front, angles prominent, sides strongly arcuate, disc moderately 

 convex, punctate, not closely, variable in coarseness. Elytra striato-punctate, 

 punctures moderately closely placed, gradually finer to apex, all the striae regu- 

 lar, the intervals flat, with a single series of fine distant punctures. Body be- 

 neath piceo-testaceous, finely strigose, the abdomen sparsely punctate. Legs 

 pale. Length .12 inch. ; 3 mm. 



From the fact that the clypeo-frontal suture may be distinct or 

 obliterated in this species, it is rather difficult to place it in an ana- 

 lytical table. The depressed form resembling the well-known quer- 

 catum with the coloration will render it readily known. The figure 

 given by Olivier is very good, so that it seems remarkable that his 

 species was not sooner identified. 



Occurs in Georgia and South Carolina. 



M. inaculipeiiiie Schwarz, Proc. Amer. Philos. Soc. 1878, p. 366.— Slightly 

 oblong, convex, rufo-testaceous, thorax darker, each elytron with three piceous 

 spots. Antennje testaceous, outer half darker. Head coarsely sparsely punctate 

 and opaque, frontal suture deeply grooved. Thorax nearly twice as wide as 

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

 convex, moderately coarsely and closely punctate. Scutellum brown or piceous. 

 Elytra" rather coarsely striato-punctate. all the strise regular, the punctures finer 

 toward the apex, each elytron with three piceous spots, one on the fifth interval 

 one-third from base, a second at the side margin opposite the fiist, the third ou 

 the seventh interval at the middle. Body beneath smooth, shining, rufo-piceous, 

 abdomen paler, sparsely punctate. Legs testaceous. Length .14 — .18 inch.; 

 3.5 — 4.5 mm. 



The piceous spots of the elytra are said to be confluent, at times, 

 in an M-like mark. The general appearance of the species is very 

 like some larger specimens of Tyyophorus sexnotatiis. 



Taken abundantly by Mr. E. A. Schwarz on Quereus virens at 

 Enterprise, Fla. 



M. pellucidiiiu Crotch, Proc. Acad. 1873, p. 43. — Entirely pale yellowish 

 testaceous, sometimes slightly darker, form short and robust. Head sparsely 

 punctate, more closely ou the clypeus. the frontal suture distinctly grooved. 

 Thorax fully twice as wide as long, slightly narrowed in front, sides strongly 

 arcuate, angles slightly prominent, disc convex, relatively coarsely, but not 

 closely punctate, smoother near the sides. Elytra but little longer than wide, 

 disc striato-punctate, the punctures feeble and entirely obliterated at sides and 

 apex. Body beneath finely alutaceous, abdomen sparsely punctate. Length 

 .10 inch. ; 2.5 mm. 



A short and robust species, the smallest in our fauna, closely re- 

 lated to pallidum in all its characters except the form.
