Thysania senobia Cramer. A single battered speci- 

 men of this great moth was picked up on the campus 

 of the State University in late September or early 

 October, 1917, and later came into the possession of 

 the writer through Mr. L. L. Buchanan, at that time 

 assistant in Entomology in the University. Smith says 

 that its range is "Florida ; Southern States ; occasional 

 northward; Colorado" (B. 44. U. S. N. M., p. 367) 

 in this country, and Holland mentions it as "a very 

 abundant species in Mexico and South America" 

 (Moth Book, 279.).

 of the same showed different species and races. I appealed 

 to my kind friends for more material and was fortunate in

 and speccies. It was then necessary to determine what
