When fully grown its average length is about one-third of an inch, 

 its diameter being rather less than one-fourth i*s length; it is 

 straight, dull-white, with a narrow dusky line along the back, which 

 is usually indistinct on the front part ; head reddish-brown, jaws 

 black at the tips, with two teeth at the apex. 



Having completed its larva growth, it leaves the fruit and burrows 

 a few inches into the ground, but instead of changing into a pupa it 

 remains in this state during the winter, and does not assume the 

 pupa form until about the first of May, according to Prof. Riley, a few 

 days before issuing as a beetle. 



This species attacks and breeds in the Haw r , which is probably its 

 favorite native fruit, also the quince and pear. 



Remedies. — As this species has the habit of dropping when dis- 

 turbed, the same remedies applicable to the plum curculio will be 

 equally effectual against it. 



Baridius trinotatus — Say. (The Potato-Stalk Weevil.) 



As I am unacquainted with this beetle, I copy the following from 

 Prof. Riley's account of it : 



The beetle is of a bluish or ash gray color, distinguished, as its 

 name implies, by having three shiny black impressed spots at the 

 lower edge of the thorax. The female deposits a single egg in an 

 oblong slit about one-eighth inch long, which she has previously 

 formed w T ith her beak in the stalk of the potato. The larva subse- 

 quently hatches out, and bores into the heart of the stalk, always pro- 

 ceeding downwards toward the root. When full grown it is a little 

 over one-fourth inch long. 



It becomes a pupa within the potato stalk which it inhabits ; and 

 it comes out in the beetle state about the last of August or the begin- 

 ning of September. The stalk inhabited by the larva almost wilts 

 and dies, and this wilting is first noticed in the latitude of St. Louis, 

 about the first of July; so far as is at present known it attacks no 

 other plant but the potato, and the perfect beetle like many other 

 snout-beetles, must of course live through the winter to reproduce its 

 species the following spring. Burn all the vines which wilt from its 

 attacks — roots and all, for it almost always works below the ground. 



Spec. char. Imago. — Body black, covered with rather short, robust 

 linear white prostrate hairs; thorax with the hairs pointing towards 

 the longitudinal middle ; at base on each side is a black dot, scutel 

 black; elytra with oblivious striae; interstitial lines flat and each 

 with about three series of the short hairs. Length three-twentieths 

 of an inch. 



Coeliodes inaequalis — Say. (The Grape Curculio.) 



This little beetle is of a black color with a grayish tint, and is 

 readily distinguished by its hemispherical form, and by the rectangu- 

 lar thorn or tooth on the upper and outer edge of each anterior and 

 middle shank or tibia. 



The larva infests the grapes during the months of June and July, 

 causing a little black hole in the skin, and usually a discoloration of 

 the berry around it. The larva, which is a footless grub scarcely a
