KEY TO EASTERN SPECIES OF CYLINDROCOPTURUS. 



a. Form rather stout, the elytra distinctly less than one-half longer 



than wide. 



6. Body clothed throughout with large overlapping scales, which con- 

 ceal the entire surface; elytra each wifli a large dark spot. 



650. BIXOTATUS. 

 66. Scales of body not overlapping; elytra without distinct rounded 



dark spot. 

 c. White mottlings of upper surface not very distinct and not ar- 



ranged to form well defined transverse bands on elytra. 

 d. Larger, 3.5 or more mm. in length. 651. orEKCULATUs. 



(Id. Smaller, not over 2.5 mm. 



e. Scales of elytra almost uniformly white, the condensed areas, 



therefore, obscurely defined; thorax finely and densely 



punctate; form narrow; length 2 mm. 652. FLORIDAXUS. 



ee. Scales of ground color of elytra dark brown, the condensed 



areas of white scales therefore more evident; form more 



robust; length 2.2 2.5 mm. 653. XAXULUS. 



cc. White mottlings of upper surface very distinct, especially on sides 



of thorax, and forming two curved interrupted cross-bars on 



elytra. 



f. Scales of median area of thorax narrow or linear; posterior 



offset of sutural white spot transverse. 654. QUERCUS. 



/f. Scales of median area of thorax large and rounded; posterior 



offset of elytral spot oblique. 654-a. var. FROXTALIS. 



oo. Form elongate, more slender; elytra one-half or more longer than 



wide; base of beak and under surface densely clothed with white 



scales. 655. LONGTJLTJS. 



650 (8817). CYLIXDROCOPTURUS BIXOTATUS Lee., 1876, 263. 



Short, ovate, robust. Dark brown, above densely clothed with grayish- 

 brown scales; elytra each with a large, median, velvety dark brown spot 

 reaching fron second to seventh or eighth intervals; scales of under sur- 

 face and legs paler; beak dark brown, polished, very finely and sparsely 

 punctate. Thorax as long as wide, feebly narrowed and slightly constricted 

 in front. Elytra at base less than one-fourth wider than thorax, their sculp- 

 ture hidden by scales. Length 2.3 2.5 mm. 



vet known from Indiana .though doubtless occurs in the 

 southern counties. Frequent about New York City in June and 

 July on dry sumac and locust. Ranges from New York west and 

 south to Ohio, Georgia and Texas. Said by Tike to occur espe- 

 cially on the honey-locust, G-lcditsia trificantJios L. 



651 (8811). CYLIXDROCOPTURUS OPERCULATUS Say, 1824, 308; ibid. II, 172. 



Elongate-subcylindrical, robust. Black, above thinly clothed with dark 



gray and white scales, the latter condensed on sides of thorax and forming 



a few very small oblong spots on elytra; beneath densely clothed with sil-
