New York, North Carolina, Utah, Washington, Texas, Illinois, 

 Colorado, Florida. I have received specimens taken in March, 

 April, Sej)tember and October, from Texas. 



The species varies considerably in coloration and distance apart 

 of the cross lines. Some specimens approach aglceella very closely, 

 and others nigricantella. I have little doubt the three forms overlap 

 each other. 



I have received from Prof S. A. Forbes, Champaign, 111., a de- 

 tailed description of this insect published in a local paper in antici- 

 pation of its proper publication in his 16th Report. By his permis- 

 sion I am able to give a full account of the larva and its methods 

 of pursuing its work, with other interesting notes on the life history 

 of the insect. 



Larva. — The general appearance of this larva is that of a dusky, somewhat 

 hairy caterpillar, paler beneath, with reddish brown head, darker in the middle
