proves most injurious ; it also attacks other pines in the same manner 

 as the preceding species. 



The most effectual remedy against the increase of these weevils, ac- 

 cording to Prof. Peck, is to cut off the shoot in August (perhaps it would 

 be best to do this somewhat earlier, as the last of June or the first of 

 July), and burn it. 



Prof. Riley says it is not met with in the West, but I find it in my 

 list of Illinois species in the 4th vol., Trans. 111. S. Agl. Repts., under 

 the name P. nemorerisis — Germ. — which is a synonym. I have there- 

 fore inserted it, as it may possibly be found injuring cultivated pines. 



Spec. char. Imago. — Snout quite slender, cylindrical, equal in size 

 throughout, directed downward nearly perpendicularly, slightly 

 curved, and a little longer than head and thorax; thorax cylindrical,, 

 much narrower in front than behind, dilated in the middle, with a 

 depression each side near the front; posterior portion nearly as wide 

 as the elytra ; a minute median carina. Elytra squarely truncate in 

 front; sides nearly parallel for two-thirds their length, abruptly de- 

 pressed near the tip; striate, and punctured in the striae, of which 

 there are ten on each wing-case ; the inter-spaces between the second 

 and third, fourth and fifth, and sixth and seventh striae or grooves 

 (counting from the suture outwards) are rather broader than the 

 others, and elevated, and the sutural margin is elevated, forming 

 slight, longitudinal ridges. Head and thorax dark-brown ; elytra 

 brown, with two rounded yellowish-brown spots on each wing-case — 

 one near the base and the other near the middle — also a white spot 

 on each behind the middle, near the inner margin. Brown beneath 

 and covered with white down. Length as given above, width about 

 one-third the length. 



Balaninus nasicus — Say. (The Long-snouted Nut-weevil.) 



This species is readily distinguished from any of those 

 already mentioned, by its long, slender snout — this is 

 slender as a bristle and about twice as long as the entire 

 body in the one now before me — it is usually only about 

 twice the length of the thorax, and is distinctly and 

 somewhat strongly curved downwards toward the tip. 



It is a dark brown color, but the thorax' is sparsely 

 and the wing-covers densely covered, especially toward 

 the tips with yellow hair, thereby giving it a rusty yel- 

 low appearance. 



This is supposed to be the weevil that attacks the 

 hazel-nut, in which it spends its larval state. 



NASICUS. 



Spec. char. Imago. — Snout very long, nearly equal to the length of the 

 body, and very slender and cylindrical, almost as fine as a bristle, strong- 

 ly curved, somewhat defiexed. Thorax cone-shaped, much narrowed in 

 front, and slightly dilated in the middle; considerably narrower be- 

 hind than the elytra. Elytra broadest in front and tapering poste- 

 riorly; the shoulders very prominent; strise numerous and very slen- 

 der, punctured very minutely. Posterior tibiae suddenly enlarged at 

 the tip. Snout dark reddish-brown, naked ; thorax and elytra covered 

 thickly with short, depressed rusty yellowish hairs, palest near the
