beyond middle. Champion regards this as a synonym of bisigna- 

 tus but it is readily separated by the characters given. 



SOI (8787). CRYPTORHYNCHUS BISIGNATUS Say, 1831, 19; ibid, I, 284. 



Similar in form and color to parochus, differing chiefly in its much 

 smaller size. Elytra less mottled with black. Thoracic carina and alternate 

 intervals of elytra less elevated. Femora either entirely unarmed or very 

 feebly bidenticulate. Length 2.5 3.5 mm. 



Lake, Starke, Putnam, Brown and Lawrence counties, Ind., 

 frequent; probably throughout the State; Apr. 30 June 10. 

 Beaten from oak and birch. Throughout New Jersey, May- 

 July, on chestnut, beech and birch, probably living under the 

 bark. Dunedin, Sanford and Sarasota, Fla., Feb. 28 March 30. 

 Eanges from Canada and New England to Michigan and Iowa, 

 south to Florida and Texas. Eecorded as occurring on the leaves 

 of oak in May (Packard) ; mating on a chestnut log in June 

 (Ohittenden) ; on a living trunk of birch infested with Scolytids. 

 (Beutenniilller.) 



Specimens from Dunedin, Fla., differ in having the form more slender, 

 scales of upper surface largely clay-yellow and fuscous, the paler ones 

 forming numerous narrow, zigzag lines across the elytra, in addition to 

 the usual oblique pale spot which is abbreviated. Length 3.2 3.5 mm. 

 They may be known as var. tessellatus. (W. S. B.) 



G. obliquefasciatus Boh., described from North Carolina, recorded from 

 Ontario, and represented by occasional specimens in many collections, is 

 a mere color variety in which the oblique white spot of elytra extends 

 from the seventh to the second stria, becoming a band, and the scattered 

 white dots are more conspicuous. Length 2.5 mm. 



802 (8789). CRYPTORHYNCHUS FUSCATUS Lee., 1876, 251. 



Oblong-oval, robust. Blackish-brown, densely clothed with pale and 

 dark brown scales and bunches of erect blackish bristles, the pale scales 

 forming some scattered spots on thorax and a broad median band covering 

 more than half of the elytra, obliquely limited in front and vaguely en- 

 closing a darker patch about middle of suture; the pale scales some- 

 times forming an indefinite oblique anterior fascia and a short trans- 

 verse fascia at apical third; the bristles arranged in five tufts on disc 

 of thorax and three or more along the third and fifth intervals of elytra. 

 Beak stout, as long as thorax, carina.te, striate. coarsely punctured near 

 base. Thorax as wide as long, sides broadly rounded, feebly narrowed 

 and constricted on apical third; disc coarsely, deeply and densely punctate. 

 Elytra one-third wider at base than thorax, sides parallel to beyond the 

 middle, stria fine, punctured; alternate intervals, except the ninth, more 

 elevated. Femora slender, not or indistinctly toothed. Length 4 6 mm. 



Whitley, Knox, Crawford and Posey counties, Ind., scarce; 

 April 26 Aug. 5; beaten from hickory. Numerous localities in
