punctured, densely scalj', a broad median stripe fuscous, sides cinereous, 

 sparsely setose. Elytra oval, moderately convex, striate, striye witli rather 

 fine, closely placed punctures, intervals flat ; surface densely covered with 

 cinereous scales, darker on the disc and with a transverse very sinuous 

 line at the declivity, and with erect black setse in regular rows on the in- 

 tervals. Body beneath densely scaly. Legs densely scaly and sparsely 

 setose. Length .M inch ; 3.5 mm. 



The surface color when deprived of scales is brownish testaceous. 



One specimen California, no special loc.ility known. 



DYSTICHEUS u. g. 



Rostrum as long as the head, robust, cylindrical, slightly flattened, A'ery 

 slightly arcuately narrowed from base to tip ; tip slightly emarginate with 

 smooth crescentic space limited behind by a ridge, upper side moderately 

 deeply sulcate, groove slightly wider toward the tip. Scrobes superior 

 very feebly convergent above, broadly open in their entire length (the 

 sides very widely divergent behind), very shallow posteriorly, not attaining 

 the eyes. Eyes moderate, coarsely granulated and surrounded by a fine 

 groove. Antenna? moderately long, scape slightly arcuate and passing the 

 anterior margin of the thorax ; fanicle 7-jointed, one-third longer than the 

 scape, first joint longest, the others elongate obconical, gradually de- 

 creasing in length ; club elongate, oval, acute. Thorax cylindrical, 

 sides moderately arcuate. Scutellum invisible. Elytra regularly oval. 

 Metasternum short, side pieces narrow. Intercoxal pi'ocess of abdomen 

 broad, truncate. Second segment of abdomen nearly as long as the two 

 following, separated fi'om the first by an arcuate suture. Anterior and 

 middle tibiae with very short mucro, tips of hind tibioe scalj'. Claws con- 

 nate. Body scaly and hispid. 



The scrobes in their entire extent are more open' than in any genus 

 known in the group. The eyes are less distinctly surrounded by a groove 

 than the following genera. I can find no foreign genus resembling it. 



D. insig-nis, n. sp. 



Form oval. Head and rostrum as long as the thorax, coarsely and 

 deeply punctured, and rugulose, and sparsely scaly and with short erect

 broader than long, apex and base truncate, sides moderately arcuate, disc 

 moderately convex, coarsely, denselj^ andxleepl}^ punctured, sparsely scaly 

 and with very short setse. Elytra regularly oval, sides feebly arcuate, 

 striate, strife with coarse, quadrate, closely placed punctures, intervals flat, 

 densely covered with cinereous scales of elongate form, with darker 

 patches irregularly intermixed, and two irregular rows of scale-like, short, 

 erect setse. Body beneath piceous, coarsely and densely punctured, abdo-
