278 CURCULIOI^ID^. 



[LeConte. 



densely rugose. Funicle O-jointed, first to third joints elongate, the tirst 

 stouter; club oval-pointed. Thighs with a very small obtuse tooth, claws 

 slender, simple. Length 3 mm.; .12 inch. 



(f. Last ventral segment with a deep transverse excavation; beak lei«8 

 than half the length of the body, stouter, densely punctured. 



9. Last ventral segment not impressed; beak half the lengtli of the 

 body, more slender and more curved, nearly smooth towards the tip, 

 strongly punctured and striate towards the base. 



Vancouver Island and California. Among many specimens before me, 

 there are only a few in which the markings are perfectly preserved; in 

 these, besides the angulated narroAV band above described, the apical part 

 of the elytra is also clothed with white scales, especially towards the suture; 

 but these scales are less densely placed than those in the band ; there is also 

 a spot at the middle of the base of the prothorax. 



13. C. obliquus, n. sp. 



Oblong, depressed, brown, densely clothed above and beneath with pale 

 brown scales, which are smaller above. Head and beak like the preceding. 

 Prothorax wider than long, rounded on the sides, strongly narrowed and 

 constricted near the tip; apical margin elevated, postocular lobes broad, 

 distinct; disc densely and more coarsely punctured than in C. angulatus, 

 deeply channeled, lateral tubercles large, acute. Elytra less broad at base, 

 strife rather shallow, punctured, interspaces wide, flat, strongly rugose; a 

 lateral oblique spot of dense whitish scales extends from the ninth to the 

 fifth stria. Other characters and sexual difterences as in 0. angulatus. 

 Length 2.4 mm. ; .09 inch. 



California at San Mateo ; three specimens, Mr. Crotch. Closely related 

 to the preceding, but more elongate, and with the scales uniform in color, 

 except the white oblique spot towards the sides of the elytra. 



13. C. tau, n. sp. 



Ovate, narrowed in front, and less so behind, depressed, blackish, densely 

 (dothed with dark gray scales, which are smaller and more fuscous above. 

 Beak curved, slender, sparsely punctured, striate towards the base. Head 

 densely punctured. Prothorax as in C. angulatus, but more obliquely 

 rounded on the sides. Elytra less oblong, more distinctly narrowed l)e- 

 hind, similarly striate and rugose, with a large scutellar spot like an in- 

 verted T> ^^^ ^'1 oblique lateral spot densely clothed with gray scales. 

 Antennte and legs brown, similar to those of C. angulatus. Length 

 3 mm.; .12 inch. 



One specimen, Texas; Belfrage. Also closely allied to the two preced- 

 ing, and differing only by form and elytral spots. 



14. O. semirufus, n. sp. 



Ovate narrowed in front, and less so liehind, brown; elytra behind tlie 

 middle, antennte and legs ferruginous; beneath densely clothed with white 

 scales; above thinly and finely puliescent, with the suture and quadrate 

 lateral spot of elytra clothed with white scales. Head densely punctured,
