NOTES ON THE TORTRICID^. 



BY PROF. C. H. FERNALD, STATE COLLEGE, ORONO, MAINE. 



At the time when my Catalogue of the Tortricidse was published, I was 

 inclined to believe that Caccecia transiturana Walk., and C. obsoletana 

 Walk., were the same species, for they were taken in the same localities, 

 and only females of the former and males of the latter species were to be 

 found in collections. 



Prof. Forbes has recently sent me two examples for determination, 

 which he bred from two lots of leaf-rollers on the strawberry, in Illinois, 

 and from each lot he obtained males and females, all the males being 

 obsoletana, and all the females transiturana. We may, therefore, con- 

 sider the question settled by Prof. Forbes, and these two insects are only 

 the two sexes of our species, which should be known as Cacoscia obsoletana 

 Walk. 



When I was examining these insects, I was struck by the close resem- 

 blance which the males bore to Cacoecia zapulata Robs. Of this species 

 only two examples, both males, are at present known \ one, the type, 

 taken in Illinois, and the other, now in Prof Riley's collection, taken in 

 Missouri. C. zapnlata is considerably larger than obsoletana. It is hoped 

 that Prof Forbes will be able to settle the question whether these two are 

 distinct from each other or not. He will undoubtedly give us the early 

 stages of obsoletana in his report. 



In the Bulletin of the Entomological Commission, No. 6, page 82, 

 Prof Riley expresses the opinion that Teras oxycoccana Pack., T. Cinder- 

 ella Riley, T. malivorana LeBaron, and T. vacciniivorajia Pack., are 

 dimorphic forms of one species. At the time when my Catalogue went to 

 press, I thought it better to allow them to appear as distinct, but made the 

 statement in a foot-note that " surely oxycoccana Pack, must be distinct." 

 I had the type of oxycoccana, and did not feel prepared to admit that an 

 insect so unlike the others could be the same thing. 



During last summer Mr. J. B. Smith collected and raised a large num- 

 ber of the so-called cranberry worms in New Jersey, and many were sent 

 to the Department of Agriculture and bred there, so that there seems to 

 be no doubt that Mr. Smith and Prof Riley have proved the dimorphism 

 of the insect. Mr. Smith had the kindness to send me a considerable 

 number for examination, but they were all the slate-colored form, or T. 

 Cinderella Riley. I therefore wrote to Prof. Riley, who sent me a gener-
