4. C obliquus Say, Cure. 38; ed. Lee. i, 396 CO; C. umbras us Boh., 

 Sell. Cure, iv, 110. 



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

 insect in deference to the statement of both Say and Boheman that the two 

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

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

 brosus. It seems to me to be a case of confusion of two species by Mr. Say, 

 similar to that recorded in the genus Calosoma; when by not obsei'ving 

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

 a very distinct species afterwards described bj^ the latter as C. Sayi. 



A— b*. 



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

 oval form, with the elytra at Ijase 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 tlie sides, narrowed in front of the middle, and 

 very strongly constricted, postocular lobes broad ; the disc is cariuate , the base 

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

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

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

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

 first; the others gradually diminishing, club elongate-oval, annulated. 

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

 lete in the smaller species; tibis nearly straight; tarsias in the preceding 

 divisions. 



The body is densely clothed with small, depressed scales, with very 

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



Thorax with an elongate median pale spot 5. obtentus. 



" sides broadly pale, disc black 6. fallax. 



Smaller, elytra with pale transverse band 7. minutissinius. 



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

 Cri/ptorhynchus ypsilon Boh., Sch. Cure, iv, 100. 



Middle and Southern States; the specimen described by 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.: .10- 

 .3 incli. 



0. C. fallax, n. sp. 



Elongate-oval, black, covered with pale brown 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-
