correctness of detail so necessary to the entomological enquirer, and which if fully de- 

 veloped might lead to some satisfactory method of diminishing if not preventing the 

 injuries caused by these destructive insects. 



More positive information is to be obtained on the following insects, and in treating 

 on these I will place them in two divisions. 



The first, containing the species which have already been described ; and the 

 second, such only as are for the first time brought forward as injurious to the cotton- 

 plant. 



In the first division may be mentioned, 



Phaljsna oblinita, Abbot and Smith's Insects of Georgia, PI. 94, p. 187. 



The caterpillar feeds on the cotton and other plants, and the moth apppears in 



April. 

 Found in Virginia and Georgia. 



Depeessaria Gossypiella, Ent. Trans., vol. iii. p. 284. 



Very destructive to the American cotton grown at Broach, in the East Indies, but 

 seldom affecting the native cotton. The larva feeds on the cotton-seed until 

 the pod is about to burst. 



In the second division I have to enumerate, 



Arctia Horsfieldii. 



Expansion of the wings 1 inch 10 lines. Anterior wings purplish ashy gray, with 

 several abbreviated obsolete, wavy, dark gray strigae, parallel to the hinder 

 margin, and a more defined zigzag, dark gray line near the base, and with an 

 elongate reniform mark on the disk beyond the middle : posterior wings brown- 

 ish orange, gradually changing to purplish gray, marked on the disk with a 

 dark gray spot, and with radiating lines of the same colour. 



The larva is yellowish white, covered with long cream-coloured hairs. The joints 

 of the body, each crossed above with an ash-gray lunulate spot, and a round, 

 rather large black spot on the upper side of the third joint. 



Feeds on the Gossvpinm herbaceum, Lin., a native of Java ; appears in the month 

 of August, according to Dr. Horsfield. 



EUDIOPTES INDICA. 



Expansion of the wings 10 — 12 lines. Anterior wings hyaline, with a broad, 

 dark brown band along the costa and hinder margin, the band rather widening 

 as it approaches the anal angle : posterior wings hyaline, with a band of the 

 same width and colour as on the anterior wings along its hinder margin, 

 gradually tapering as it approaches the anal angle. 



Larva smooth, pale grass-green, with the head yellowish. 



Feeds on the Gossypium herbaceum, and on the Corollodendron, common in Java 

 from January to April, according to Dr. Horsfield. 



This species is nearly allied to Pyralis hyalinata, Lin., but is nevertheless quite 

 distinct.
