NORTH AMERICAN COLKOPTERA. 215 



rufescent space near each eye. front sparsely punctate, more coai^ely on the cly- 

 peus; labrun, pale. Thorax nearly twice as wide as long, sightly narro.^d n 

 Lnt sides broadly arcuate, margin very evident, angles prom.nent he antenor 

 the mo.-e distinctly, surface sparsely and very finely punctate, a htt e more dis- 

 tinctly at the sides. Elytra scarcely a fourth longer than wide, str.ato-punctate 

 tri. all regular, the punctures becoming finer toward the apex Body beneat^h 

 smooth, abdomen sparsely punctate. Legs piceous black, tars, paler. Length 

 .20— .24 inch. ; 5—6 mm. 



The larger measurement is on the authority of Dr. LeConte, as 

 none in my cabinet are of that size. 



In our lists this species appears as a synonym of chibwsa bay on 

 the authority of Mr. Crotch, who had evidently not seen the species 



described by Say. 



Related to 31. mhim, but distinct in the arrangement of the colors 

 and by the sculpture of the head. In suturale there is uo frontal 



fovea. 



Occurs in Texas, Waco (Belfrage). 



M terminale n. sp.-Form slightly oblong, similar to sutnrah, piceous 

 blick shining, apex of elytra testaceous, sometimes extending narrowly to the 

 humerus Autenn^ yellowish testaceous. Head sparsely punctate, slightly 

 opaque, clypeus paler. Thorax nearly twice as wide as long, slightly narrowed 

 in front, sides strongly arcuate, angles feebly prominent, d.sc convex, almost 

 absolutelv smooth, the punctures very fine and distant. Elytra stnato-punctate, 

 stria, all" regular, punctures coarse and deep, nearly as wide as the intervals, 

 becoming ol^olete near the apex. Body beneath smooth, shining, abdomen 

 sparsely finely punctate. Length .16-.19 inch. ; 4-5 mm. 



The legs are usually rufo-testaceous, but a specimen from Key 

 West has black legs. This has also the pale space at the elytral 

 apex very indistinctly defined. 



AVhile closely related to suturale, this species is quite distinct by 

 the characters given in the table. 



Occurs in Florida, Biscayne Bay and Key West (Schwarz). 

 M peniiisnlare Crotch, Proc. Acad. 1873, p. 42.-Very like ustum in form 

 and color Head brown, coarsely but not closely punctate. Antenuse rufo-tes- 

 taceous. darker toward the tip. Thorax brown", nearly twice as wide as long, 

 scarcelv narrowed in front, sides strongly arcuate, angles prominent, disc mod- 

 eratelv" coarsely and closely punctate, a smooth median line posteriorly, a little 

 more finely punctate near the apex. Elytra piceo-testaceous with darker suture, 

 coarselv and closely striato-punctate, intervals flat and smooth, stvuv all regular. 

 Proploune with a few scattered punctures. Abdomen sparsely P""^-t'*;^e. Legs 

 piceo-testaceous, the femora darker beneath and at the knees. Length .20-.2i 

 inch.; 5 — 5.5 mm. 



This species is readily known among those with the small tooth 

 on the hind femora, by the closely and coarsely punctate thorax.
