Cenopis pettitana Rob. 



A yellowish green, brown headed, sparsely haired caterpillar a little over ^4 inch 

 long occurs on oak and rose. 



This is another rose leaf roller, which may occasionally be injurious 

 aryd is likely at any time to invade greenhouses and possibly destroy buds. 

 The adult flies, according to Dr Lintner, in early July. The moth has 

 been described by Dr Robinson as follows : 



Palpi pale yellow above, ochreous or brownish ochreous beneath. 

 Head and thorax above pale lemon-yellow, sometimes of a deeper shade. 



Anterior wings very pale yellow or lemon-yellow, shining. Costa in 

 the male with two aggregations of brownish ochreous scales at basal and 

 apical third. 



Posterior wings and fringes pure shining white. 



Under surface of both pairs, and abdomen, above and beneath, pure 

 white. 



He states that the wing spread of the male is about 7/g inch, and that 

 of the female ranges from the same to about \^/% inches. He gives its 

 habitat as western Canada, Ohio, Illinois, and as stated above, it has been 

 recorded from New York. Dr Dyar lists it from the Atlantic States. Dr 

 Robinson states that this is a quite variable species, and an examination of 

 specimens from Illinois resulted in the following description made on the 

 spot : " Head, thorax and palpi above, clear lemon-yellow, the latter brown- 

 ish ochreous laterally and beneath. Upper surface of primaries in both 

 sexes lemon-yellow ; the costa covered with brownish ochreous scales to 

 one third from base. Hind wings above and under surface of both pairs
