336 LEPIDOPTERA. 



from the very characteristic drawings of Mr. Glover. The 

 larva closely resembles that of L. rosaceana and is about the 

 same size. It rolls up the leaf of the cotton into a loose cir- 

 cular fold, and when full}^ grown spins a thin, loose, transpar- 

 ent cocoon between the leaves. 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 re- 

 tained in place in the cocoon. The moth is the size of the 

 L. rosaceana, being pale reddish brown, and with three darker 

 bars, the inner one crossing the costal two-thirds of the wing, 

 the middle and broadest crossing the wing obliquely, and ter- 

 minating near the outer angle, Avhile the third bar cuts off the 

 apex of the wing. The hind wings are paler, but duskj- along 

 the inner side. 



The species of PentJiina may be recognized b}^ the oblong 

 fore wings, the apex being obtuse, sometimes a little falcate. 

 An interesting species, according to information received from 

 Mr. M. C. Reed of Hudson, Ohio, rolls up the leaves of the 

 grape, and when the fruit becomes formed, eats the pulp and 

 seeds, thus doing a two-fold injury to the vine. It may be 

 called the Penthina vitivorana (Plate 8, fig. 22, enlarged). The 

 head, thorax and palpi, and basal half of the antennae are ful- 

 vous. The fore wings are dark slate brown. From the mid- 

 dle of the costa proceeds a blackish band which curves to the 

 middle of the outer third of the wing ; be^'ond is a linear curved 

 costal band succeeded by another broader but quite short costal 

 line ; the costa is tawny beyond, sending a tawnj^ patch obliquely 

 inwards. Near the margin is an irregular blackish patch and 

 two dark spots on the costa, and a larger one at the apex. The 

 hind wings and body are dark slate color. It expands .40 of an 

 inch. The first brood of caterpillars feeds on the leaves, ap- 

 pearing in May (in Ohio), or as soon as the leaves are grown. 

 The second brood appears when the grapes are nearly tilled 

 out, and then they feed on the pulp and seeds. Mr. Reed writes 

 me that "in every instance where a grape was opened contain- 

 ing a fully grown larva, the seeds were mere shells. The}' con- 

 tinue their work until the grapes are fulty ripe, and at that 

 time on removing to a new beny, seem to make their home in 

 the old one, which is attached b}^ a web." The larva turns
