Atlantic States, abundant, especially near the sea shore. Quite distinCI 

 from all tlie preceding by the absence of erect set«, and by the scales being 

 narrow, hair-like and extremely small. It is abundant and widely diffuse* 

 in Europe, but the American race differs from the European by the oolo# 

 of the scales being more rusty and less gray.

Widely diffused in Europe, where it varies greatly in size. I have re- 

 ceived several specimens from Canada, collected by Mr. W. Couper. as 

 types of the synonym above mentioned. It lias perhaps been introduced 

 in earth around roots of shrubs or trees ; though I have one specimen frum 

 Kansas, one from Hudson Bay territory, and several from Dacota.

Europe, and Northern Asia; Oregon, and California. I have three spec- 

 imens from Oregon, referable to this species, which is easily known by 

 the very small size, narrow form, and absence of distinct erect setae ; tiie 

 covering is squamose, grayish-white, obscurely striped on the prothoras, 

 feebly banded on the elytra. Length 3.3 mm; 13 inch. 



Sub-Family II. ALOPHID^. 



Tlie small group of Curculionidte, represented in Europe hy AUphu,^, 

 and in our fauna by several other genera, is sufficiently distinct in its oral 

 structure to warrant its reception as a sub-family. The convex oval elytra, 

 without humeral angles, and with the posterior part strongly deflexed, 

 added to the more or less rounded prothorax, give an appearance not unlike 

 certain Otiorhynchidaj; and the prolongation of the antennal grooves to 

 the tip of the rostrum, which is ratlier stout, increases the resemblance. 



There are, however, radical differences in the mandibles; wliich are nearly 

 flat externally and punctured; pincer-sliaped, with a sharp edge attheape.x, 

 which is more or less emarginate, and witiiout a|)ical scar or deciduous 

 piece. The mentum is tolerably large, trapezoidal and flat, retractc<l witf*. 

 the gular peduncle, which is broad ; the posterior edge of the latter i» 

 prominent, so that the mouth appears hollow; the maxillaj are exposed, as 

 are also the ligula and palpi. 



The beak is as long as the prothorax, rather stout, usually a little wid?f 

 at tip, with distinct apical wings; the tip is feebly emarginate. and markL«|
