The lower leaves of corn were first attacked, and then the "worms" 

 fed on the tender unfolded leaves higher up. 



June 30 of the same year Mr. Webster again sent the larvae of this 

 species from Lafayette, Ind., where it was also found feeding on corn. 



October 28, 1890, we received the larva from Mr. F. W. Mally, 

 Holly Springs, Miss., where it was found feeding on cotton. 



June 6, 1896, we received the larvae from Prof. F. H. Snow, Law- 

 rence, Kans., with the report that they were destroying late-planted 

 corn in Clay County of that State, eating both leaves and stalk down 

 to the ground. 



We have also obtained the larva from Raleigh, N. C, reported on 

 cottonwood. 



Some of the above facts have been briefly repeated by Mr. Webster 

 in Bulletin 45 of the Ohio Agricultural Experiment Station (p. 187). 



ECONOMIC LITERATURE. 



This species has received comparatively little attention in economic 

 literature. In the Tenth Report of the State Entomologist of Illinois 

 (p. 139), Mr. John Marten makes mention of the feeding of the cater- 

 piller on salsify. This note, however, was based upon observations 

 made in confinement, and there is no evidence to show that the insect 

 sought the salsify from choice. 



In Insect Life (Vol. II, p. 382) Mr. F. M. Webster notes the occur- 

 rence of full-grown larvae at Lafayette, Ind., October 29, 1888. In 

 the same, publication (Vol. Ill, p. 119) Mr. Webster states that the 

 larvae were observed in considerable numbers in April, 1888, in Ten- 

 sas Parish, La., depredating upon young corn. They were also 

 observed the same month riddling the leaves of cabbage in gardens, 

 as also in St. Francis County, Ark., ravaging fields of potatoes, eating 

 every vestige of a leaf from them. June 26, of the same year, young 

 larvae were observed at Lafayette, Ind. , feeding upon the parenchyma 

 of leaves of wheat, and a few days later upon cabbage. Still later 

 they were feeding upon the foliage of late-planted corn. 



In Bulletin 21 (o. s.) of this Division (p. 21) Mr. F. W. Mally notices 

 the occurrence of the larva on cotton and states that it enters nearly 

 grown bolls, feeding on their contents in much the same manner as 

 the boll worm. Mr. Ashmead also noticed this species feeding upon 

 cotton bolls and records the fact that it had been observed attacking 

 young cotton plants as they appeared above ground, acres being some- 

 times destroyed and having to be reset to secure a good crop. The 

 pupal stage was ascertained to be between twelve and thirteen days in 

 August in Mississippi (Insect Life, Vol. VII, pp. 321, 325). 



The occurrence of this cutworm upon asparagus at Berwyn, Md., 

 and in the District of Columbia, in August and September, 1896, has 

 been recorded by the writer (Bui. 10, new series, p. 60)
