CRYPTORHYNCHINT. 231 



carinate; punctures large, shallow, indistinct on account of the pubescence. 

 Elytra one-half wider at base than the prothorax, humeri prominent, ab- 

 ruptly rounded; striae composed of distant, oblong punctures; interspaces 

 finely rugose, flat; third, fifth, seventh and ninth finely but not strongly 

 carinate. Body beneath coarsely punctured; mesosternum protuberant; last 

 ventral segment with three very faint impressions. Thighs feebly annu- 

 lated, with a broad, obtuse tooth. Length 7 mm.; .28 inch. 



Kansas, Mr. E. A. Popinoe, one specimen. The rows of punctures of the 

 elytra, from the absence of pubescence, appear black; the white dots oc- 

 cupy the distance between them, and contrast elegantly with the yellow 

 pubescence of the main surface. The white lines of the prothorax are nar- 

 row, and not very conspicuous; they converge but scarcely meet at the 

 front, and are slightly curved ; the middle carina is also clothed behind with 

 white hair; the scutellum and a small spot at the base of the third inter- 

 space of the elytra are also white. 



12. C. similis Boh., Sch. Cure, iv, 416. 



Southern States. A large, (6.2 mm. ; .25 inch), and robust species clothed 

 with short, ferruginous pubescence, and handsomely variegated with 

 white, forming a complex pattern each side of the prothorax, and irregular 

 posterior bands on the elytra. The beak is long and slender, punctured, 

 feebly striate; the prothorax broader than long, not narrowed from the 

 base to the middle, then rounded and much narrowed to the tip, which is 

 strongly constricted at the sides; the disc is very densely punctured, and 

 finely carinate from the tip to the middle. The punctures of the elytral striae 

 are very large and quadrate, and the alternate interspaces are finely cari- 

 nate. Body beneath coarsely and rather densely punctured; mesosternum 

 protuberant ; abdomen with three rows of more densely pubescent spots; 

 first and second ventral segments more sparsely at the sides; fifth ventral 

 feebly impressed at the tip. Thighs armed with a large, acute tooth. 



The beak in the tf is half as long as the body, opaque, punctured, finely 

 striate towards the base, with the antennae inserted about one-third from 

 the tip; in the female the beak is much longer, about three-fourths the 

 length of the body, polished, not striate, feebly and sparsely punctured, 

 with the antennae inserted behind the middle. 



13. C. naso, n. sp. 



Blackish brown, thinly clothed with dirty brown pubescence. Beak 

 brown, slender, curved, one-half as long as the body, shining, indistinctly 

 punctured, finely striate towards the base. Prothorax wider than long, 

 rounded on the sides, suddenly narrowed and constricted near the tip; very 

 densely, rugosely punctured, carinate, marked with two small discoidal 

 spots of white pubescence. Elytra one-third wider than the prothorax, 

 more sinuate at base than usual, humeri more advanced in front, and 

 rounded; striae composed of small, closely placed quadrate punctures, alter- 

 nate interspaces finely carinate; surface more densely pubescent, and with 

 rows of very short bristles, indistinctly banded transversely. Under surface
