a large blowsand area. It is more or less accidental in the sand 

 prairie associations. 



Py rain CIS cardui Linn. April 7. 



Several of these butterflies were seen at the Devil's Neck, flying 

 about over the blowsand. They are very abundant forms, are two- 

 brooded, and visit a number of different food-plants. Hardly typical 

 in sand prairie. 



Callosaiiiia pvoiiictlica Dru. July 11. 



.\ common large saturniid moth. Cocoons abundant on sand- 

 bar willow {Salix lougifoUa) on the sandy shore of Matanzas Lake. 

 Not typical of sand prairie, however. 



Apantcsis sp. (larvce). April 4. 



The lan^ie of an Apantesis were taken under a log in the bunch- 

 grass. These larvae are very active, usually feeding upon plants of 

 low growth. Another arctiid, Bubaphe aurantiaca brevicornis Walk., 

 was found by Mr. Hart quite frecpiently on sand-dunes. 



Diacrisia I'irgiiiica. Fab. April i. 



Two pup?e were taken at the edge of bunch-grass, in a hollow 

 log. The moths emerged later; one about April 20, and the other 

 about Ma}^ 15. The larvae belong to the type of caterpillars known as 

 "woolly bears." The species is generally distributed, and is very 

 destructive in certain localities. 



Nocfita c-nigrum Linn. April i. 



Taken in fence-row, under boards, in the larval state. The 

 noctuid caterpillars are known as cutworms, from their under- 

 ground habit of cutting off stems. They are very characteristic of 

 grass-land and cultivated crops. A number of cutworms occur regu- 

 larly in the bunch-grass associations. Whether these species are 

 the same as those which were present before the cultivation of the 

 region, is a difficult ciuestion. The adult noctuids were frequently 

 seen flying about in the bunch-grass, though they are very much 

 more active at night. 



Fcltia subgothica Haw. April i, 4. 



This is the commonest species of the genus, and the most abun- 

 dant cutworm of the bunch-grass. Quite generally distributed. 



Mamestra meditata Gr. April i. 



Found with other cutworms in fence-row under boards, A com- 

 mon species of economic importance.
