margin two oblique lines of the same color. On each wing-case there are three or four 

 more or less distinct whitish lines, occupying interstriate spaces. These whitish lines 

 are sometimes almost obsolete. The under side is dark, but thickly covered with short 

 whitish hairs which give it an ashen color. Length as given above. 



Epicxrus wibricattis, Say. Imbricated Snout-beetle. 



This species, whose general color is a dull silvery white, with brown 

 or dark markings, is confined chiefly to the west side of the Mississippi 

 river. As it is frequently found in Missouri and Iowa, I have introduced 

 it here that our orchardists may know it if they should meet with it. Its 

 history is not known, as it has never been traced through its transforma- 

 tions. In the perfect state it sometimes does more or less injury to apple 

 and cherry trees, and to gooseberry bushes, according to Prof. Riley, by 

 gnawing the twigs and fruits. I have not observed it at any point in this 

 State, yet I presume it will be met with occasioiially. 



Spec. Char. Imago. — Body covered with dense, minute, somewhat imbricated 

 scales, without intervals ; above, dusky brassy or blackish, punctured ; head with a pro- 

 found puncture between the eyes ; rostrum with a dusky line in the middle ; thorax a 

 dorsal, slightly impressed, punctured line, and several dilated, indented punctures cov- 

 ered with scales ; a dilated, cinereous, dorsal line; elytra with very slightly impressed 

 striae, containing profoundly impressed punctures ; sides and tip white, the latter exhib- 

 iting an undulated outline above ; three subequidistant, equal, white spots each side of 

 tjjfs suture, and another at the middle of the base ; an oblique line from behind the hu- 

 merus terminates at the middle. 



Length three-tenths of an inch. 



This species varies in depth of coloring, and the cinereous, subsutural 

 spots are sometimes confluent with branches from the margin, so as to 

 form three cinereous bands, but I believe that the spots at the base are 

 always insulated. 



Pandeletius hilaris, Herbst. Gray-sided Curculio. 



According to Dr. Harris, this is a little, pale brown beetle, variegated 

 with gray upon the sides. Its snout is short, broad and slightly furrowed 

 in the middle ; there are three blackish stripes on the thorax, between 

 which are two of a light gray color ; the wing-covers have a broad stripe 

 of light gray on the outer side, edged within by a slender blackish line, 

 and sending two short oblique branches almost across each wing-cover ; 

 and the fore legs are much larger than the others. The length of this 

 beetle varies from one-eighth to one-fifth of an inch. The larva lives in 

 the trunks of the white oak, on which the beetles may be found about the 

 last of May and the beginning of June. 



LONGIROSTRES. (Long-snout Beetles.) 



The .species belonging to this section are distinguished by the elon- 

 gate snout, which is cylindrical, and decidedly narrower and longer than 

 the head, and by having the antennae inserted near its tip. The body is 

 generally elongate and almost cylindrical, and covered with a fine dust or 

 powder, usually of a bluish or orange color, which is easily rubbed off".
