INSECTS INJURING OAK-LEAVES. 195 
272. Cenopis pettitana (Robinson). 
The caterpillar of this variable species is said by Miss Murtfeldt to 
feed on the oak, hickory, and rose. 
Professor Riley found at the same time (May 15, 1869) as Cacoecia 
argyrospila, a large grass-green oak roller with a black head and a pale 
brown cervical shield and bluish dorsal line, with the thoracic legs 
black. June 3, 1869, five moths issued. 
Zeller (November 20, 1871) says it is near the European Xanthosetia 
hamana, but differs. 
Several of them entered the chrysalis s^ate May 26, 1869. 
October 9, 1872, received from Manhattan, Kans., a larva feeding on 
oak, which possesses several of the characteristics of Perophora mel- 
sheunerii. (Riley's unpublished notes.) 
Larva. — Length, .625 of an inch; diameter about .10 across the head, which is the 
broadest part. Pale yellowish green, somewhat flattened, line, medio-dorsal line, 
piliferous spots on dorsum very minute, sides somewhat tuberculated, with con- 
spicuous longitudinal row of long, stiff brown hairs arising from brown plates. 
Head large, dark brown, not polished, horizontal. First segment horny, pale brown, 
constricted behind, roughened like the head with dense minute punctures. Anal 
plate orbicular, large, horny, with a glistening whitish punctured surface, with two 
conspicuous purple-brown spots and a dark longitudinal dorsal line. Larva forms a 
case of web- work on the leaf or between two leaves. Moths issued in early May. 
Pupa. — Differs materially from that of Cacoecia argyrospila. It is .55 of an inch in 
length. The antennae and legs reach exactly as far as wing sheaths. The color is 
very dark brown, and after the moth has left the posterior third behind last row of 
teeth is of a lighter reddish brown in contrast. Two rows of teeth on principal 
abdominal segments, as in Cacoecia argyrospila. The extremity is blunt with scarcely 
any hooks visible, though occasionally a very fine one may be seen. (Riley's unpub- 
lished notes.) 
Moth. —Fore wings very pale yellow. Costa in the male with two patches of 
brownish ocherous scales at the basal aud apical third. Expanse of wings, 22 to 
28 mm . (Robinson). 
273. THE RED-BANDED LEAF ROLLER. 
Lophoderus triferanus (Walk.). 
Order Lepidoptera ; family Tortricid^e. 
Probably originally feeding on the oak, elm, and maple, as well as the 
cranberry. The caterpillar occasionally damages clover, corn, straw- 
berry, bean, etc. The following notes are copied from Forbes' 3d Eep. 
Ins. Illinois: 
This species occurs somewhat rarely in Illinois, and has not been reported through- 
out its wide range to do any injury except to the cranberry in Massachusetts, where 
its larva is locally known as one of the cranberry worms. We bred it, however, 
during this past season from pale-green leaf-rollers in young corn, and consequently 
may regard it as worthy of brief mention, especially as its local abundance in cran- 
berry plantations in Massachusetts would indicate a capacity for excessive multipli- 
cation which makes it a possible source of danger in the great corn-fields of the 
Mississippi Valley. 
The presence of this larva and of that of the sulphur leaf -roller, just treated, is 
indicated in corn-fields by the folding lengthwise or rolling of the leaves in May and
