Life history. The nests of tliis species be^^an to ajjpear |une 13, 1901, 

 and were common on the 26tli antl later. Inliabiled webs were alscj taken 

 July 27 and others .\in^. 9. The period of iHi^du is probably extended and 

 the insect appears to breed more or less durin;^ the summer months. 1 he 

 web is rather small, irrei^ular, measurin;^ 3 to 4 inches lont^ and 2^.4 to 3 

 inches in diameter. It is tilled with a mass of excrement, as in allied 

 species. A number of small, dark colc^retl catirjjillars about - 5 inch lontj 

 were obser\ed in the nests alter most of the moths had appeared. The)' 

 close!)' resemble full sj;^rown lar\ae and may have been retarded intlividuals. 

 Unfortunately none of the latter were brought to maturity. 



Natural enemies. This species is preyctl on by several parasites. 

 M i c r o c e n t r u s tl e 1 i c a t u s Cress, and M. s o 1 i d a g i n i s Cress. M.S., 

 have been r(;ared, from this insect. .Several parasites were Ijred from this 

 species and a plant buj;', probably P o d i s u s p 1 a c i d u s Uhl., presumably 

 preys on the lar\ae. 



V-marked leaf roller 



.Ircliips aroyrospi/a Walk. 



Delicate green, brown-headed caterpillars about -'-4 inch long, feed on oak and other 

 trees in early June and also in .August orearly September. 



This species is very closely allied to the obli(]ue banded leaf roller, 



A r c h i p s r o s a c e a n a 1 iarr., ami like it is a j^a-neral feetler, having been 



recorder! on oak, hickory, ajjple, wild cherry, rose, soft ma|:)le and elm. It 



lives between the webbed-together leaves and produces two generations 



annually, the moths of the first a|)|)earing the latter part of June or early in 



July. The lar\a has been described b\' I )r I'ackard as follows: 



Color delicate grass-green, with a darker tlorsal vesicidar line, not 

 polished, i^ilifcrous spots polished ; head brown, cervical shield jjolished, 

 glasslike, and scarcely darker than body ; anterior edge lighter. .Thoracic 

 legs pale.
