THE GENERIC POSITION OP GRAPHOLITHA (?) CMC AS A. V^ 



Illinois, who, whilst Dr. C. Thomas was State Entomologist of 

 Illinois, was one of his assistants. As it is from the work 

 of Dr. C. Thomas that the paper on Hessian Fly, published by 

 the Entomological Commission of the U.S.A., is stated by Dr. 

 Packard to be mainly prepared, and as Mr. J. Marten (Dr. 

 Thomas's assistant) has especially devoted himself to the study 

 of this insect, his opinion is one of much value. 



I have now the honour to mention to the Society that in 

 every condition, from that of slightly-changed larva up to imago 

 watched through all its changes of colour, the insect under 

 discussion corresponds with the Cecidomyia destructor of Say ; 

 that the injury to the corn-stalks also corresponds exactly; and, 

 further, that I have received the confirmation of these points on 

 personal examination of my specimens from the high authorities 

 mentioned above. To this I may add that the work of the later 

 brood is also now (or up to my last communication) on the self- 

 sown, or late-sprouted plant, as described in the States. The 

 figures which accompany I have drawn from life.* 



THE GENERIC POSITION OF GRAPHOLITHA^}) CMCANA. 



By J. W. TuTT. 



I THINK it is nearly time that the true position of the little 

 Tortrix ccecana was settled in our list in a satisfactory manner. 

 It is, I believe, a general opinion among those who know 

 anything about the insect that it is altogether out of place in the 

 position Mr. South has assigned it, viz., at the end of our present 

 genus Grapholitha, a position, as my friend Mr. Coverdale 

 remarked (Entom. xviii. 219), " which seems about as bad a 

 place as one could find for it." 



When Mr. Coverdale first discovered the species in this 

 country in July, 1884, he described it under its continental 

 name, Grapholitha ccecana. I suppose most of our entomologists 

 know that there is a greater difi'erence between the continental 

 and British generic divisions of the Tortricina than between 

 those of any of the other large groups, and that our genus
