689 (8845). CEUTORHYNCHUS PUSIO Mann., 1852, 355. 



Oblong-oval, subclepressed. Dull reddish-brown, antennae and legs paler; 

 head, under side of body and sometimes the thorax and basal portion of 

 elytra dark piceous; above rather thickly clothed with small, pale brown or 

 grayish-yellow scales, condensed on sides of thorax and near scutellum, 

 those of the under surface somewhat larger and paler. Front broadly con- 

 cave; beak as long as head and thorax, male, one-fourth longer, female, fine- 

 ly punctured, feebly carinate and scaly toward base. Thorax one-half wider 

 than long, strongly constricted at apex, apical margin elevated, postocular 

 lobes wanting; lateral tubercles small, acute; dorsal channel feebly im- 

 pressed, disc densely and rather finely punctured. Elytra longer than wide, 

 one-fourth wider at base than thorax, sides subparallel from base to beyond 

 middle, then gradually converging to apex; striae fine, intervals wide, 

 finely rugose. Claws with a short, acute basal tooth. Last ventral of 

 male with a deep rounded fovea, of female with a circular impression. 

 Length 2.2 2.5 mm. 



Newport, R. T. ; June 26 July 11. Cape Cod, Truro and Nan- 

 tucket, Mass. Sitka, Alaska, LeConte collection. Occurs along 

 the ocean beach on the American sea-rocket, Calf lie edcntula Bigel 

 and beneath kelp. C. liaiiiUtoni Dietz is a synonym. There has 

 been much confusion over this species. One of the two specimens 

 mentioned by LeConte as having been sent him from Sitka by 

 Prof. Mseklin is at Cambridge, and differs from C. liamiltoni 

 Dietz only in having the elytra slightly darker on basal two- 

 thirds. Specimens of the next species, described by Dietz as 

 pusio and also specimens of an apparently undescribed species 

 from Kansas, were placed by the side of the true pusio bearing 

 the Sitka label, while LeConte had two additional species from 

 the western states also labelled pusio. The sea-rocket above men- 

 tioned, on which liamiltoui is recorded as feeding, occurs on the 

 Pacific as well as the Atlantic coast and also along the Great
