 jpiieoiis lustre; iuiteniue usually more or less brownish; pubescence sparse or 

 moderate. Beak ^ '^ ) as long as the head and i>rothorax. not stout, moderately 

 arcuate, slightly dilated, minutely longitudinally sti'igose nearly to the tip, finely 

 punctured above, more coarsely serially at the sides, a confluent line of punctures 

 over the insertion of the antennae ; ( 9 ) not or very little lunger than in the % , 

 mure slender and shining, not dilated, very sparsely, minutely pnuctulate 

 throughout. First joint of the autennpe subequal to the next two, not reaching the 

 eye; eyes moderately prominent; front with a median sulcus, on either side of 

 which is a confluent line of punctures. Prothorax wider than long; apical con- 

 striction moderate; middle nearly or quite as wide as the base, before which 

 there is usually a slight sinuation ; surface rather closely punctate; basal fovea 

 small, elongate. Elytra about one-half longer than wide; humeri prominent; 

 sides parallel or feebly diverging to the middle; intervals nearly flat, scarcely 

 twice as wide as the strife. Beneath sparsely punctate, more closely at the sides 

 of the metasternnin and abdominal segments. Length 1.7-2 mm.; .07-. 08 inch. 



% . Sutural angles rounded; middle and hind tibia; with a moderately long, 

 nearly .simple niucro.

Hub. — New York, Pennsylvania, New Jersey, District of Colum- 

 bia, Michigan, Illinois, Arkansas, Texas. 



A female example in Dr. Dietz's collection, labelled Yuma, Cal., 

 does not differ tVom eastern specimens, except in having the first

 Atlantic region, and is said by Dr. Hamilton to occur on Vacciniinn 

 stratiiineatii,.

 slender, a little longer than the head and prothorax, scarcely dilated ; supra- 

 antennal groove not well defined ; punctuation fine, sparse: surface more or less 

 shining beyond the insertion of the antennae, according to the distinctness of the 

 finer sculpture: superior margin of antennal fovea distinctly angulate. Front 

 punctate, more or less plainly sulcate: eyes moderate. Prothorax wider than 

 long, widest at the base ; apical constriction about as usual ; basal sinuation feeble ;
