by the elytra intervals having a series of white hairs, while in 

 pygmaeus they are entirely glabrous. The specimens have been in 

 the collection under the above manuscript name, which has been re- 

 tained for them. 



OLIGOMERUS ARBUTI, new species. 



Slender, subcylindrical, brown. Head rather strongly deflexed. 

 Eyes round, moderate in size. Antennae 11-jointed; joint 1 large, 

 about twice as wide and three times as long as 2 ; joints 2 and 3 

 subequal, longer than wide, the second wider than third and more 

 oval; joints 4 to 8 subequal, slightly wider than long; joints 9 to 11 

 subequal, the ninth about equal in length to the three preceding, 

 triangular, slightly longer than wide, the eleventh oblong, and two 

 and one-half times as long as wide. Prothorax with side margins 

 entire, narrowly margined, edge not serrate; front angles distinct, 

 rounded; posterior angles very broadly rounded and not well de- 

 fined ; disk evenly rounded, not gibbose ; surface finely granulate and 

 sparsely clothed with short, prostrate reddish-brown pubescence. 

 Elytra equal in width to the prothorax, one and three-fourth times 

 as long as wide, feebly striate, the striae not noticeably punctured, 

 but are interrupted by the granulation which causes them to have 

 the appearance of a series of long dashes; surface finely thickly 

 granulate and sparcely clothed with fine, prostrate reddish-brown 

 pubescence. Front coxae contiguous. Middle coxae narrowly but 

 evidently separated, the mesosternum acute posteriorly and reaching 

 to the middle of the coxae. First joint of posterior tarsi equal in 

 length to the three following joints united; third and fourth joints 

 emarginate at tip. Length, 3 to 3.5 mm. ; width, 1.5 mm. 



Habitat. — Placerville, California. Described from three speci- 

 mens recorded under Bureau of Entomology Number Hopk. U. S. 

 11719&, collected February 16, 1914, by Mr. J. J. Sullivan on dead 

 Manzanita {Arhutus, species). 



Type.— Cat. No. 21427, U.S.N.M. 



This species differs from all other North American species, except 

 obtusus LeConte, by having 11-jointed antennae, and from which it 

 is easily distinguished by not having the prothorax gibbous and the 

 elytral striae less coarsely punctured. 



ERNOBIUS CONICOLA, new species. 



Eather robust, uniform brown in color in both sexes, shining, 

 clothed with rather long conspicuous, recumbent yellow pubescence. 

 Head granulate-punctate; eyes large, the width of the front between 

 them not more than one and three-fourths times their vertical 

 diameter in the male, and about twice their vertical diameter in the 

 female. Antennae 11-jointed, nearly as long as the body in the male, 

 and somewhat shorter in the female ; all joints longer than wide ex-
