Thi.s ytvikintrly marked species is quite commonly taken at light in 

 the vicinity of Washington City. It was described by Zeller from 

 Massachusetts, while Clemens' specimen came from Maine. In the 

 National Museum are specimens from Illinois, Iowa, New York, Mis- 

 souri, District of Columbia, and Georgia. 



Mr. Coquillett recorded the food plant as sunflower {Ilellanthus). 

 It has l)een bred b}^ Miss Murtfeldt and in the insectary of the ^ 

 Department of Agriculture from SoUdago^ from which plant I have 

 also bred it, I am sorry to say without sufficiently careful notes to 

 be able to give the differences between the larv« of this and of the 

 following species, inserrata Walsingham, which are quite similar. I 

 have even a suspicion that the two species may prove to be varieties 

 of one species. 



TRICHOTAPHE INSERRATA Walsingham.

 Trichotaphe imerrata Busck, Dyar's List Amer. Lep., No. 5656, 1902. 



This species has been bred by Miss Murtfeldt and myself from Soli- 

 clago^ and is commonly found in company with the foregoing species 

 among these plants. 



The type is in Professor Fernald's collection, where I have com- 

 pared it with specimen from U. S. National Museum. 



The species comes to light fro(>ly. i
