380 SUBFAMILY X. CURCULIONINJE. 



nearly as long as the next two united. Thorax convex, one-fourth wider 

 than long, narrowed from the base, sides broadly rounded, constricted 

 near apex, disc punctured as described in key and with a narrow, smooth 

 median line. Elytra! striae rather fine, not deep, feebly punctate; inter- 

 vals wide, flat, finely and densely rugosely punctate. Prosternum of male 

 with a large, deep, oval median excavation in front of coxae and with a long, 

 curved, pointed horn each side the cavity. Length 4.5- 6.2 mm. 



Lake Co., Incl., scarce; May 24 June 10. Originally described 

 from a single male from Missouri. No other record of its occur- 

 rence can be found. LeConte described the type as black; Casey 

 gave its color as piceous ; but the type and all the ten specimens 

 at hand are dark brown, the head alone piceous. Easily known 

 by the vittate elytra, large size and prominent prosternal modifi- 

 cations of the male. 



Centrinus striatirostris Lee., (1876, 309). Short-oval, very robust; 

 dark brown, above sparsely clothed with elongate whitish scales ar- 

 ranged transversely on thorax and condensed each side of scutellum on 

 elytra; thorax nearly twice as wide as long, obliquely striate; elytra with 

 coarse, deep, punctate striae and flat, coarsely punctate intervals. Length 

 4.4 4.6 mm. A Texan species, recorded, probably erroneously, by Dury 

 from Cincinnati, Ohio. He states that the specimen was so named 

 for him by Dr Horn, but is not now in his cabinent. 



575 (8924). CENTRIXUS MODESTUS Boh., Schon., 1836, 772. 



Oval, robust, strongly convex. Dark brown or piceous, sparsely 

 sprinkled with broadly oval white scales and narrower brownish ones 

 above, and more densely clothed with whitish scales beneath. Beak 

 nearly half as long as body, rather stout, evenly curved, coarsely punc- 

 tate and striate on sides, sparsely and finely punctate above. Second 

 joint of funicle one-half as long as first, slightly longer than third. 

 Thorax wider than long, strongly constricted near apex; disc with a 

 narrow median smooth line, punctate as mentioned in key. Elytra 

 oval, their sides strongly converging from near base; striae deep; in- 

 tervals coarsely punctate, each puncture enclosing a large white scale. 

 Prosternum of male with a deep smooth impression near front margin, 

 the coxal processes as described in key. Length 4 4.5 mm. 



Dunedin, Fla., Nov. 9. Recorded from "Middle and Western 

 States" by LeConte; also from Pennsylvania, Ohio and Florida. 

 "In well preserved specimens a small spot of dense scales is evi- 

 dent each side of scutellum and another just before each humeral 

 callus/' (Casey.) 



576 (8928). CENTRINUS PICUMXUS Herbst, 1797, 30. 



Oval, convex. Dark chestnut brown to black, legs paler; above 

 densely and uniformly clothed with long, more or less narrow, pale clay- 

 yellow to whitish scales; those of under surface paler, denser and 

 much wider. Beak slender, one-half as long as body, tapering, strongly
