Supplementary Report on Insects Affecting the Strawberry. 237 



"The worm is pale livid, greenish above and paler beneath, with a con- 

 spicuous black dot on each side of the hinder edge of the prothorax. The 

 head is ver}- pale honey-yellow, with two black spots, one near the insertion 

 of the mandibles and the other on the side, near the base of the head. The . 

 posterior half of each segment is transversely wrinkled a few times. The 

 body is scattered over with a few minute tubercles, each giving rise to a fine 

 hair. It is .80 of an inch long. 



"One specimen spun its slight cocoon on June 2r)th, the pupa appearing 

 June 30th. It is sometimes attacked by ichneumons. 



" The pupa is pointed on the vertex of the head, and on the back of each 

 abdominal ring are two rows of spines. On the abdominal tip of the brOwn 

 cocoon are three pairs of minute hooks, the two outer pairs supported on a 

 pedicel, by which the chrysalis is retained in place in the cocoon. The moth 

 usually appears the last of June. There is a second brood in August." 



It will be seen that this is a much larger species than the true strawberry 

 leaf-roller, and it may also be distinguished by the different manner of its 

 injury to the plant, as it folds the leaf more loosely than the other. 



The periods of this species are such as to render it susceptible to the same 

 treatment as that already found effective for the strawberry leaf-roller proper. 



The Plain Strawberry Leaf-Roller {Caccecia obsdetana, Clem.) 

 Order Lepidoptera. .Family Tortricid^. 



Another leaf-roller extremely similar in general appearance to the above, 

 but not hitherto known as injurious to horticulture, was discovered by us in 

 Southern Illinois this year. From the oblique-banded leaf-roller it diflered 

 especially in the form of the wings, which had scarcely a trace of the charac- 

 teristic sinuosity of the front and outer margins of the latter species, and in 

 the obsolete character of the oblique band of the front wings, here reduced 

 to two brown spots, one on the cost;U, and the other on the internal margin 

 of the wing. 



The larva is a plump, smooth, green caterpillar, about an inch long, con- 

 colorous except the head, the first thoracic segment, and the legs. The head 

 is yellowish, with the anterior margin and the mouth parts brown. The 

 ocelli are four in number, arranged in a semicircle at the side of the head 

 the two anterior being much larger than the others. There are two or more 

 long hairs on the vertex, and a number of others collected about the ocelli. 



The first thoracic segment is brown and leathery above, but with a few 

 long hairs which are not set on tubercles. At each end of this dorsal Icath- 

 bery plate is a white spot set in a dark blotch. The two remaining thoracic 

 segments have each a single transverse row of six pale piliferous tubercles, 

 the row being double at the ends; but all the other segments except the 

 penultimate have two rows. These tubercles arc nuu-h the largest on the pos- 

 terior segments, and the rows extend entirely around the foui^h, fifth, tenth, 

 eleventh and twelfth, — those which are destitute of prolegs.
