elytra are not tesselate, but striped, and the sides of the prothorax are more 

 rounded, as in S. sordidus.

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

 from all the preceding by the absence of erect setae, and by the scales being 

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

 in Europe, but the American race differs from the European by the color 

 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 has perhaps been introduced 

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

 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 setas ; the 

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

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



Sub-Family II. ALOPHID^]. 



The small group of Curculionidae, represented in Europe by Alophus, 

 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 Otiorhynchidae; and the prolongation of the antennal grooves to 

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



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

 flat externally and punctured ; pincer-shaped, with a sharp edge at the apex, 

 which is more or less emarginate, and without apical scar or deciduous 

 piece. The mentum is tolerably large, trapezoidal and flat, retracted with 

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

 prominent, so that the mouth appears hollow; the maxillae are exposed, us 

 are also the ligula and palpi. 



The beak is as long as the prothorax, rather stout, usually a little wide* 

 at tip, with distinct apical wings; the tip is feebly emarginate. and marked 

 also in the first two genera with a deep angulated impression, from which
