THE BED STRIPED CRANBERRY WORM. 



In the latter part of September and early part of October I found on 

 a bog in New Jersey a few specimens of a larva described by Dr. 

 Packard under the above name ; the specimens agree very well with his 

 description, which is substantially as follows : 



The body is long and slender, nearly three-fifths of an inch in length, 

 slightly tapering to the head, but more decidedly toward the tail ; 

 general color pale livid green with six longitudinal, pale reddish lines, 

 broken and irregular toward the head, but more distinct and wider 

 toward the tail, so that the body looks darker and rather more reddish 

 posteriorly. The head is pale yellowish with a few long hairs; the man- 

 dibles are reddish, darker at the tip. Ocelli blackish. Prothorax un- 

 usually long, nearly as long as the head, and entirely without markings; 

 it is slightly wider than the head, but narrower than the succeeding 

 segmeut. On the front edge of the second and third rings is a trans- 

 verse row of six black, minute warts giving rise to a hair, and a seventh 

 one low down in the middle of the side. On the abdominal segments 

 there are four dorsal black warts, the two anterior nearer together than 

 the posterior, though not forming a decided trapezoid ; on the side of 

 the ring is another black wart in line with the two anterior dorsal ones 

 and giving rise to a rather stout hair. Around the edge of the supra- 

 anal plate is a row of four black warts and two median, dorsal, smaller 

 warts. Beneath, livid greenish, the three segments between the last 

 pairs of feet with each a transverse, straight row of minute, black 

 warts. 



The habits of this caterpillar are much like those of the Teras and of 

 the Anchylopera ; like them it draws together the leaves of a spray, but 

 unlike them it often severs the leaves and forms a complete tube of silk 

 with au outer covering of leaves ; this tube is always open at each end, 

 and the larva, which is very active, slips out at the least disturbance. It 

 was found on a single spot only, and in small numbers, and this spot 

 was just the on* 5 part of the bog not flowed during the winter. At date 

 (October 22), the larvae have not yet pupated, while the bogs are either 

 entirely or nearly covered with water. The remedy is indicated by the 

 length of larval life, and it consists simply in flowing the bog as early in 

 the fall as it can be safely done and before the larva changes to the pupa 

 stage. The fact that I found this larva in the only part of the bog not 

 flowed, and not elsewhere, is significant and points to the best remedy. 



Some other insects have been recorded as feeding on, or in some way 

 injurious to, the cranberries, but these are all observed by me during the 

 past season. Some of them may be found in Massachusetts or elsewhere,, 

 on bogs that I did not get to see, but I heard no complaints of other 

 insects from localities which I have visited, except that Mr. Makepeace, 

 of Hyannis, Mass., who has probably the largest acreage of cranberries- 

 under his care of any one man in Massachusetts, complains of a root
