1-34 FIRST ANNUAL REPORT OF 



Naturalist (p. 220) is quoted an account of it by Mr. M. C. Read, of 

 Hudson, Ohio, who says that it is "already so abundant there thai i! is 

 necessary to examine every bunch of ripe -rapes, and clip out the in- 

 fested berries before sending them to the table." 



The larva of this Grape-codling may at once be distinguished 

 from that of the Grape curculio, by its having 6 scaly legs near the 

 bead, 8 fleshy legs in the middle, and 2 at; the extremity of the body, 

 and by spinning a fine web, by which it lets itself drop whenever 

 handled. It is also larger, of a darker color, and bears a very close 

 resemblance to that of the Strawberry leaf-roller, to be hereafter fig- 

 ured and described. 



Its presence is soon indicated by a reddish-brown color on that 

 side of the yet green grape which it enters. On opening the grape, a 

 winding channel is seen in the pulp, and a minute white worm with a 

 dark head is seen at the end of the channel. It continues to feed 

 upon the pulp of the fruit, and when it reaches the seeds, eats out 

 their interior. As it matures it becomes darker, being either of an 

 olive-green or dark brown color, with a honey-yellow head, and if one 

 grape is not sufficient it fastens the already ruined grape to an adjoin- 

 ing one by means of silken threads, and proceeds to burrow in it as it 

 did in the first. When full grown it leaves the grape and forms its co- 

 • coon on the leaves of the vine. This operation i- per- 



ormed in a manner essentially characteristic: the 

 vorm cuts out a clean oval flap, leaving it hinged on 

 me side, and, rolling this flap over, fastens it to the 

 iil.eaf, and thus forms for itself a cozy little house which 

 it lines on the inside with silk. One of these cocoons 

 is represented at Figure 76, 5, and though the cut is sometimes less 

 regular than shown in the figure, and I have had them spin up in a silk 

 handkerchief without making any cut at all, it is undoubtedly the 

 normal habit of the insect to make just such a cocoon as represented. 

 In this cocoon, within two days, it changes to a chrysalis, such as is 

 represented at Figure 76, «, of a honey-yellow color with a green 

 shade on the abdomen ; and in about ten days more the moth makes 

 its escape, the chrysalis having first pushed itself almost entirely out 

 of the cocoon. The moth is of a slaty-brown color with corky-yellow 

 markings, and is represented enlarged at Plate 2, Figure 29, and of 

 the natural size at Figure 30. 



imens of this moth were sent by Mr. Walsh to the English 

 Lepidopterist, 11. T. Stainton, who could not refer it to any known ge- 

 nu.- bul Dr. Packard, of Salem, Massachusetts, refers it to Penthina 

 a genus very closely allied to Carpooapsa, to which our Apple Cod- 

 ling moth belongs. He has also kindly furnished me with advanced 

 sheets of Part V of the "Guide to the Study of Insects," in which (p. 

 336) he describes and figures it under the name of PentJiina vitivor- 

 ana. The description is quite brief, however, and the figure not good,
