Texas. This species has been long known under the name here 

 adopted, but I cannot find that it has been published. It is of the 

 size and general form of C. pnnctulata, but quite different in its cha- 

 racters, which ally it to C. abJominalis. The white hairs are sparse, 

 and visible only on the under surface ; the series of large punctures 

 usually seen on the elytra near the suture are not distinct, or barely 

 perceptible. 



C ab<IoniiiiaIiK. 



A singular race of this species was found by Messrs. Hubbard and 

 Schwartz, at Cedar Keys, Florida. The specimens diifer from those 

 found in Georgia and New Jersey, as well as from others collected in 

 Florida, by the elytra being quite strongly and deeply punctured; the 

 large punctures or foveae near the suture are also deeper. Otherwise I 

 can discover no difference, and am therefore unwilling to characterize 

 this peculiar form as a distinct species. 



C, margiiiipeiinis Dej. 



Mr. F. G. Schaupp has informed me that during the past summer 

 he collected this species at Calicoon, Sullivan Co., New York. The 

 only locality previously known is at Harrisburg, Penna. It will prob- 

 ably be found at various points in the upper valleys of the Susquehanna 

 and Delaware rivers. 



C. striga. — Dark bronze, with a slight olivaceous tinge, shining. Head 

 large, scarcely concave between the eyes, which are large and prominent; a 

 few short lines are visible each side between the eyes. Prothorax not longer 

 than wide, convex, with a few distinct rugiB, especially near the tip and base, 

 front transverse impression deep, hinder one indistinct, dorsal line faint, sides 

 moderately rounded. Elytra elongate oval, humeri distinct, surface sparsely 

 but strongly punctured, subsutural foveae large and deep, tips rounded, not ser- 

 rate ; apical lunule narrpw, bent obliquely inwards and forwards at the anterior 

 extremity; medial band represented by a submarginal whitish spot. Body be- 

 neath thinly clothed with white hairs. Labrum transverse, truncate in front, 

 and subsiuuate each side; maxillary and labial palpi pale, with the last joint 

 dark. Length 13.5— 16.5 mm. ; .53— .65 inch. 



^. — Labrum white, nearly rectilinearly truncate in front, medial tooth 

 obsolete. 



5 . — Labrum brown, truncate and subsinuate in front, medial tooth large 

 and acute. 



Lake Harvey, Florida, May 4th, Messrs. Hubbard and Schwartz. 

 This species is allied to C. severa, but is quite different by the polished 

 surface, the deeper punctures of the elytra; the form of the labrum, 

 which is without a tooth in % , and only unidentate in 9 ; by the 

 maxillary palpi bt'iug al.-jo pale, with only the last joint dark; by the 

 head not concave between the eyes, and with fewer rugae near the
