126 CURCULIOXID M. 



[LeConte. 



extending to the second stria, as in P. setigerus, and the European P. 

 Pollux. Antennae piceous, first joint of funiculus but little longer than the 

 second. Tibiae and tarsi testaceous. Length .5 mm. ; 20 inch. 



Vancouver Island, one specimen. Very like several European species, 

 but easily distinguished by the coarse pubescence of the prothorax unmixed 

 with scales. The last joint of the funiculus is closely attached to the club. 



6. P. Castor, n. sp. 



More elongate, blackish, head and prothorax very finely pubescent with 

 gray hair; front wider, with a fovea behind the eyes. Prothorax a little 

 longer than wide, a little wider at the middle, narrower in front than at 

 base, rounded on the sides, densely punctured, trivittate with white. 

 Elytra one-third wider than the prothorax, oblong oval, humeri rounded, 

 striae punctured ; clothed with very small scales so deeply bifurcated as to 

 resemble fine hairs ; also with rows of very short pale setse ; gray, varied 

 with brown, and tesselated with small black spots ; the darker quadrate 

 basal spot is not very distinct. Antennae with the first joint of the funi- 

 culus about one-third longer than the second. Legs blackish. Length 

 5 mm. ; 20 inch. 



Canada, one specimen. More elongate than the European P. Pollux, 

 and easily distinguished by the finely pubescent prothorax and the rows of 

 short setae of the elytra. The last joint of the funiculus is quite separate 

 from the club. The scales of the elytra are very small and quite peculiar 

 in form, giving the appearance of very fine hairs arranged by pairs. 



7. P. nigrirostris Gyll.,Seh. Cure, ii, 393; Cap., Ann. Ent. Fr. 1868, 

 227; RJiyncliatnus nigr. Fabr., Syst. El. ii, 428, &c., &c. 



This common European species occurs in Canada and in Massachusetts. 

 It belongs to Capiomont's seventh group Phytonomidius, in which the 

 first joint of the funiculus is much longer than the second, which is not 

 longer than the third. 



8. P. quadricollis, n. sp. 



Blackish -brown, covered with a very dense coat of dirt colored small 

 rounded scales, mixed with a few very short sub-erect hairs, which form 

 rows upon the elytra. Beak as long as the prothorax, cylindrical, about 

 three times as long as wide, glabrous, and nearly smooth at tip, which is 

 reddish-brown; feebly carinate; frontal fovea small, distinct. Eyes oval 

 transverse, not narrowed beneath, not prominent. Prothorax nearly 

 square, very slightly narrowed in front, sides scarcely rounded, base feebly 

 rounded; sculpture concealed by the scales. Elytra more than half wider 

 than the prothorax, oblong oval; humeri abruptly rounded, sides then 

 parallel, rounded at tip; striae impressed, punctured, punctures almost con- 

 cealed by the scales; interspaces nearty flat, third a little more convex. 

 Antennae brown, first joint of funiculus as long as the two following ; 

 second very little longer than the third. Length .5 mm. ; .20 inch. 



One specimen from Dacota, Mr. E P. Austin. Very different from the 

 other species by the nearly square prothorax. The ventral segments are
