This species is amenable to the same remedies as the greenhouse 

 leat'-tyer, considered in the initial article of this bulletin. 



The presence of the caterpillars on roses is so obvious as to be easily 

 detected, and all that is necessary in many cases when the}" are found 

 in the leaves is to crush them between the thumb and forefinger. If 

 the greenhouse is not fumigated the only remedy after the caterpillars 

 have attacked the ])uds is to cut off the buds and l)urn them, or destro}^ 

 them l)y crushing under foot. 



Owing to the concealed manner of life of the larva it is doubtful if 

 insecticides would be of much value when the insect is found on roses 

 in gardens, hence hand methods nuist l)e resorted to. 



The larva} of a number of other moths, mostly Tortricida?, attack 

 roses in mucli the same manner as the rose bud- worm. Some of the 

 best known of these may l)e briefly mentioned. 



THE ROSE LEAF-TYER. 



[Penthina cyannna Murtf.) 



A species closel}^ related to l\nt]i 1 )ia n ! inhatana is P. cf/r/nana^ which 

 was described by Miss Murtf cldt in 1880 (Amer. Ent., Vol. Ill, pp. 

 14-15). The habits of this species do not appear to differ mater iall}^ 

 from those of T*. nimhatana. It is more a})undant on roses growing 

 in the open, but according to Mr. G. C. Davis it also attacks roses in 

 greenhouses. Of its injuries at Kirkwood, Mo., Miss Murtfeldt wrote 

 that it was occasionally so abundant as to devour or mar fully 20 per 

 cent of the rosebuds, especially of white or light-colored varieties. 



Among the notebook records of the Division of Entomology this 

 is stated to have been found by the late Dr. Riley in injurious num- 

 bers on his roses at Washington during the summer of 1879. July 6 

 of the next year he received rosebuds containing larv?e, which were 

 reared to the adult, from Mr, Henr}^ Plumb, Pleasanton, Kans. 



This species was found at work on roses at Alexandria, Va., by Mr. 

 T. A. Keleher, of this office, in July, the imago issuing in the middle 

 of that month. 



The recorded distril)ution of this species comprises portions of the 

 states of Missouri, Kansas, Penns3dvania, and Michigan, and to this 

 list may be added the District of Columbia. 



As in manner of life all these rose pests are similar, the j-emedies to 

 be applied are the same. 



THE OBLIQUE-BANDED LEAF-ROLLER. 



{Cacfrcia rosareana Harr.) 



One of the most important of the leaf-rollers, fi'om the economic 

 point of view, if we consider its injuries to all its food plants, is
