HACKBERRY MOTHS. 609 



SO many of the Acronyctas, are ia the habit of resting iu a curved 

 position. The chief peculiarity of the larva is that it changes the color 

 of its tufts and hairs at the last larval molt. 



OTHER LEPIDOPTERA. 



Some other Lepidoptera occur on the Hackberry, but none of them are 

 peculiar to it except, perhaps, the Tortricid and the Tineids. It will 

 suffice therefore, in closing this brief chapter, to indicate some of the 

 species which occur on Celtis, and which also occur on other trees and 

 have been already treated of by Dr. Packard in other chapters of this 

 report. 



6. P(cdisca celtisana Riley (Trans. Ac. Sc. St. Louis, 1882.) 



7. Lagoa opercularis Abbott and Smith. — Never very common, but 

 widespread and a general feeder. My notes show that it occurs also on 

 Oak, Orange, Apple, Pear, Plum, Viburnum, Poplar, Willow, Sassafras, 

 English Ivy, and one has even been found on Ailanthus — a tree affected 

 by so very few insects. 



8. Sphinx drupiferarum Abbott and Smith. — This is also a not very 

 common but widely distributed species occurring from Florida to Canada 

 and from the Atlantic States to the Mississippi, while varieties are 

 found iu the extreme Western States, in California, and even in Van- 

 couver. While its principal food-plant seems to be Prunus, Abbott and 

 Smith give also Celtis. Miss if. Middleton (10th Ills. Kept, on Noxious 

 and Beneficial Insects, p. 104) also gives Celtis as one of it food-plants, 

 while Professor Fernald, in his "Sphingidse of New England," adds 

 Apple and Lilac. 



9. Mamestra sp. ? — A larva quite closely resembling that of Mamestra 

 subjimcta has been found on the Hackberry, but unfortunately not 

 reared. The same species has also been found on Polygonum, Plantain, 

 and Clover. 



10. An unbred Geometrid larva resembling somewhat that of Aletia 

 xylina Say has also been found on Celtis at St. Catherine's Island, 

 Georgia, by Mr. Schwarz. 



11. Proteoteras (esculana Riley. — This species, which commonly feeds 

 on the Buckeye, has been sent to me by Mr. L. Bruner from West 

 Point, Nebr., on the short twigs of Celtis occidentalis. What is, with- 

 out much doubt, the same species, has also been found upon the young 

 shoots of Maple [Acer dasycarpum) as also of Box Elder {Negundo ace- 

 roides). 



12. Lithocolletis celtifoUella Chambers. — This is recorded by Cham- 

 bers as making a tentiform mine on the underside of the leaves of Celtis 

 occidentalis. 



13. Lithocolletis celtisella Chambers. — This species, first recorded by 

 Chambers in 1871 {Canadian Entomologist^ Vol. Ill, p. 129), I have also 

 reared plentifully from mines on the leaves of Celtis collected in Vir- 

 ginia in 1884.
