August, '10] PIERCE : ECONOMIC WEEVILS 365 



fessor K. A. Cooley and Mr. E. A. Schwarz to describe a second species 



in one of these genera. 



Table of Species 

 Scales luteous to brown, with darker discal spot ou elytra; length 3-5 



mm chrysorrhceus Say- 

 Scales iridescent white to shining ochreous, slightly mottled on elytra but 



not forming a distinct spot; length 3-3.5 mm artemisice n. sp. 



Cercopeus artemisicB n. sp. 



Size 3-3.5 mm. Color black to piceous, densely covered, above and below 

 with round, slightly overlapping, white or ochreous, finely striulate, appressed 

 scales, which are iutex*mixed with long, fine, white setae; elytral intervals 

 uniseriately setigerous. Beak slightly longer and narrower than head, 

 clothed with scales to tip, with a smaller interocular fovea, and a median 

 line toward apex; scrobes superior, deep in front, shallow behind, not reach- 

 ing eyes by a distance subequal to their own length. Antennae rufous; scape 

 reaching thorax, scaly and pubescent; club about equal to the last four funi- 

 cular joints. Eyes rounded, moderately convex; ommatidia relatively large, 

 separately convex, giving the appearance of a flattened raspberry. Thorax 

 transverse, basally and apically truncate, laterally broadly arcuate. Elytra 

 not one half longer than wide; humeri obliquely rounded; striae as seen with 

 scaly vestiture complete, very fine but sharp; intervals clothed with from 

 three to five rows of closely placed pavement scales, but uniseriately setiger- 

 ous. Under-sides densely scaly; front coxae contiguous; middle coxae very 

 narrowly separated; intercoxal process truncate and transversely impressed 

 before apex. Second abdominal segment about equal to two following, fifth 

 longer. Femora and tibiae densely scaly; anterior and median tibiae strongly 

 mucronate; tarsal claws strongly divergent. 



Described from nine specimens collected by R. A. Cooley at Corval- 

 lis, Montana, May, 1909, injuring cherry trees, but evidently native to 

 Artemisia tndentata. Prof. Cooley writes that the "species was re- 

 ported doing considerable damage over large tracts of newly planted 

 orchards. It was particularly injurious on cherry trees. I examined 

 the trees and traced the beetle to a species of Artemisia tridentata I 

 think. I believe the species feeds normally and breeds on this plant. 

 I accounted for its presence in the orchards by the fact that its normal 

 food plant was cleared off, leaving little else for the beetle to eat 

 other than the fruit trees." Type Cat. No. 13083 U. S. N. M. 



Family CURCULIONIDJE 



Subfamily Ceutorhynchinae. 



Ceutorhynclius Germar 



The following species belongs in the true Ceutorhynchus, with 7- 

 jointed antennre, and in Dietz's "squamatus group." The first sec- 

 tion of that group can be distinguished as follows :
