This larva, though legless, walks readily, and; like those of all 

 other beetles known to me, never uses its head by way of foot to assist 

 its progress, as those of almost all two-winged Midges and Gnats 

 (Diptera nemocera) commonly do. Neither does it curl up, belly 

 inwards, in a semicircle, as do the larvse of many other Snout-beetles, 

 and as does more especially the common White Grub {Laclinosterna 

 quercina, Knoch) and its numerous allies. All the specimens seen 

 by me, whether from Ohio or Kentucky, were in green grapes and of 

 a pale color ; but Mr. Spaulding, of Cobden, has assured me, that the 

 darker the grape is, the darker the larva becomes. 



The Grape Curculio. {Cccliodcs inceqiialis, Say.) Fig. 1. Black, with 

 minute, short, scale-liJvC, appiessed white hairs, so as to give the black a gray- 

 ish tint. Head, including the beak, punctured almost as coarsely as the 

 thorax; beak reaching a little beyond the base of the middle pair of legs, 

 nearly cylindrical, curved inwards in a circular arc of about 60 degrees, and 

 sometimes tinged with brick-red. Thorax with rather large confluent punc- 

 tures, its sides converging in a convex quadrant for % of the way from 

 base to tip, thence to the tip converging very gradually in a straight line. Tip 

 of thorax about one-half as wide as its base, and squarely docked with a 

 slight central excavation (emargination) ; its anterior edge always more or 

 less tinged with brick-red. A transverse impressed line for % of the 

 way from the scutel to the tip of the thorax; and a deeply impressed dorsal 

 longitudinal line, which after crossing the transverse line becomes much 

 fainter. On each side of the deeply impressed part of the dorsal line is a 

 very large rounded tubercle, and outside this, but rather nearer the base, and 

 almost on the lateral edge of the thorax, is a smaller subacute tubercle. Re- 

 gion of the scutel impressed. The nnng-cases (elytra) are slightly freckled 

 with small gray spots caused by the greater denseness there of the scale-like 

 white hairs; their grooves {strice) are punctate with large, widely separated 

 punctures; and the respective interstices between the 2d and 3d, the 4th and 

 5tii; the 6th and 7th, and the 8th and 9th grooves are wider and, especially 

 the first two, more highly elevated and rounded in front than the others. 

 The lower surface of the body is punctvired like the thorax, but much more 

 sparsely. The legs are of a more or less dull brick-red, the thighs unarmed, 

 the four front shanks with a large rectangular tooth near their outer base, 

 the hind shanks unarmed. Near the outer tip of each shank a few stiff, 

 short bristles. Length of the body 0.09 — 0.11 inch. 



Described from eleven species, bred September 2d — 6tli from infested 

 grapes of the same year's growth. Two specimens, captured at large many 

 years ago in Illinois and now in mj' cabinet, agree in all respects with the 

 others. I had originally referred this species to Ceuthprhynchus (cceliodes) 

 curtus, Say, as it agrees pretty well with Say's description of that insect, 

 after inserting a phrase which has apparently, through some clerical or typo- 

 graphical error, been omitted in the printed editions ; for otherwise the word 

 "smaller" in Say's description is unmeaning and unintelligible. After in- 

 serting the omitted phrase in brackets. Say's description would read as fol- 

 lows: "Each side [of which line is a large rounded tubercle, and outside of 

 this tubercle] rather behind the middle is a smaller subacute tubercle." But
