by Mr. C. N. Ainslie. The nineteen specimens in the collection 

 of the U. S. National Museum bear locality labels from Devil's 

 River, Dallas, Victoria, Sabinal, Kerrville, Piano and Browns- 

 ville, Texas, one simply "Ariz." and one taken at light at 

 Washington, D. C. From these scattered data no definite 

 limits for the distribution of the species can be fixed but in 

 spite of its comparative rarity it appears to be widely diffused. 

 The map below shows the location of the above mentioned 

 localities.

 has been collected. 



Food Plants. Nothing is known of the normal food plants. 

 Larvas were easily reared to maturity on bluegrass {Poa pra- 

 tensis) and doubtless would have accepted any one of a large 

 number of grasses in common with other species of the genus. 



Seasonal History. Zeller states that the moths fly in 

 Texas during the last half of May. The first moths seen by 

 the writer were those taken at Chattanooga on June 1 1 . Others 

 were taken at Wellington, June 27, and at Elk Point, July 19. 

 All of these were captured alive and sent at once to the Bureau 

 Field Laboratory at Nashville, Tenn., where eggs were obtained 

 and larvae reared from each lot. The larvas from the Chatta- 

 nooga moths pupated as soon as mature and adults emerged 

 on August 5, 7, 11, 14 and 15. Part of the larvae from the 

 Kansas moths pupated as they reached maturity and moths 

 emerged August 23, 26, 30, and September 2 and 13. The rest 

 of the larv£e in this series did not pupate but continued slowly
