Middle States; our largest species. I only restore the name of Say to this 

 inseet in deferenee to the statement of both Say and Boheman that the two 

 names represent the same speeies. My own preference would be to ignore 

 this assertion altogether, to call No. 3 C. obliquus, and the present one um- 

 brosus. It seems to me to be a case of confusion of two speeies bj^ Mr. Say, 

 similar to that recorded in the genus Calosoma; when by not observing 

 very obvious differences, he sent to Dejean under the name of C. calidunt, 

 a very distinct speeies afterwards described by the latter as C. Sayi. 



A— b*. 



The speeies representing this division in our fauna are of an elongate - 

 oval form, with the elytra at base but little wider than the prothorax ; the 

 humeral angles are obtusely rounded not very prominent; the sides are 

 parallel, then obliquely narrowed to the tip. The prothorax is wider than 

 long, much rounded on the sides, narrowed in front of the middle, and 

 very strongly constricted, postoeular lobes broad ; the disc is carinate , the base 

 broadly emarginate each side, with the angle in front of the scutellum verj' 

 small, not prominent. Scutellum small, white. The beak is as long as the 

 prothorax, rather stout, somewhat flattened; the antennae are inserted 

 about the middle of the beak; funicle slender, second joint as long as the 

 tirst; the others gradually diminishing, elub elongate-oval, annulated. 

 Thighs slightly clavate, armed with a single tooth, which is nearly obso- 

 lete in the smaller species; tibi» nearly straight; tarsias in the preceding 

 divisions. 



The bod}' is densely clothed with small, depressed scales, with very 

 short, stout bristles intermixed, which in C. apiculatus become spines. 



Tliorax with an elongate median pale spot 5. obtentus. 



" sides broadly pale, disc black 6. fallax. 



Smallei', elytra with pale transverse band 7. minutissimus. 



Alternate spaces of elytra with a row of spines 8. apiculatus. 



5. C. obtentus. CurcuUo obt. Herbst, Kafer, vii, 38, pi. 99. fig. 2. 

 CryptorTiynchus ypsilon Boh., Sch. Cure, iv, 100. 



Middle and Southern States; the specimen described bj' Herbst was evi- 

 dently badly preserved, and the median pale line of the prothorax had dis- 

 appeared; normally this line is wider at the middle, of a narrow lozenge- 

 shape, and includes a dark central spot. When the front part is abraded it 

 assumes a Y-shape. The third and fifth elytral interspaces are strongly 

 elevated; the femoral tooth is quite distinct. Length 5.3-7.5 mm.; .16- 

 .3 inch. 



6. C. fallax, n. sp. 



Elongate-oval, black, covered with pale l)rown scales, with intermixed 

 short bristles; disc of prothorax and large common triangular spot on elytra 

 black. Beak strongly punctured, as long as the prothorax, flattened, scarce-
