804 (8790). CRYPTORHYNCIIUS OBLIQUUS Say, 1831, 28; ibid, I, 296. 



Oval. Black, densely clothed with dusky, black and white rounded 

 scales; thorax with three black spots; elytra each with two black spots in 

 front of a common whitish oblique band on basal third and with a similar 

 band behind the middle; antenna? and tarsi reddish-brown. Beak about as 

 long as thorax, coarsely and rather densely punctate and carinate on basal 

 half, somewhat flattened, smooth and shining towards tip. Thorax scarcely 

 wider at base than long, strongly narrowed in front, sides moderately round- 

 ed; disc densely and rather finely punctate, the median carina abbreviated 

 in front. Elytra one-third wider at base than thorax, humeri and apex 

 obtusely rounded; alternate intervals moderately elevated, subconvex, the 

 others flat. Ventral segments coarsely and sparsely punctured, the fifth with 

 a deep circular impression in male. Denticles of the femora small, close 

 together. Length 7 9 mm.

805 (8791). CRYPTORHYNCIIUS HELVUS Lee., 1878, 431. 



"Very similar to G. obliquus and differing only in the following char- 

 acters: Scales pale yellow-brown, slightly variegated with darker; form 

 of body a little narrower. Thorax a little longer than wide, sides obliquely 

 narrowed from the middle, where they are rounded to apex, nearly parallel 

 behind the middle. Elytra with the intervals wide and flat. Thighs with 

 one small, acute tooth. Length 7.8 mm. Except for the difference in the 

 form of thorax I would consider this as merely a variety of obliquus." 

 (LeConte.)

 The type and only known specimen is in the Cambridge collec- 

 tion. 



806 (8793). CRYPTORHYNCHUS LUTOSUS Lee., 1884, 31. 



Elongate-oblong. Black, densely clothed with dark brown scales and 

 a few short, stout bristles intermixed; elytra with scattered paler brown 

 scales at base and forming a transverse band near apical third. Beak 

 slender, naked, as long as thorax, finely and sparsely punctate and with a 

 deep punctured groove each side; front with a small deep fovea. Thorax 

 as wide at middle as long, not carinate, sides parallel behind the middle, 

 then obliquely rounded to apex, behind which there is a broad shallow con- 

 striction; disc prolonged above, densely, finely and deeply punctate. Ely- 

 tra one-third wider than thorax at base, humeri obtusely rounded, sides 

 parallel to apical third, then converging to the rounded apex; striae compos- 

 ed of large distant punctures; intervals flat. Length 5.7 6 mm.
