He also stated that they were very numerous near Huntington, W. Va. 

 On July 29, newly-hatched larvae of the second brood were found at the 

 first-mentioned locality feeding upon the new crop of leaves which had 

 developed on the trees defoliated by the first brood. Many pupse were- 

 found about four inches below the surface of the soil, under the trees. 

 Larvae were observed feeding on Catalpa trees at several points in Athens^ 

 Vinton, Jackson, Gallia and Meigs counties during the summer. In the 

 latter county about one thousand four-year-old Catalpa trees in the nur- 

 sery row had been stripped of two crops of leaves in each of the past two- 

 years, and many of them were dead and the remainder are practically^ 



worthless. 



The greatest damage reported was at Jackson, where both species of 

 Catalpa have been planted quite extensively for street trees. Many of 

 them have been entirely defoliated two or more times in each of the past 

 three years. The worms were numerous enough to become a nuisance 

 when they were full grown, as they left the trees and crawled about seek- 

 ing suitable places to enter the ground to pupate. Frequently, when su 

 tree was badly infested, the leaves were all eaten before the larvae were 

 mature, and in their search for other trees many of them wandered, over 

 the lawns, walks, porches and even into the houses. This has caused a. 

 few residents of that city to have their Catalpa trees cut down. 



Dr. J. B. Smith states that the range of this species is "from Virginia. 

 to Florida; westward to the Mississippi; as far north as Indiana." It 

 has been gradually- spreading northward during the past few years. The 

 pest -was reported from southern Indiana in 1890 and again in 1905 ; at 

 Lexington, Ky., in 1893, and Delaware county, Pennsylvania, in 1898. 

 In New Jersey it has been reported as far north as the latitude of Dela- 

 ware, Ohio, and is said to be not only holding its own but gradually ex- 

 tending out into the country districts. 



In the Southern States there are three or four broods, the last one 

 hibernating in the pupa state beneath the ground, the moths emerging the 

 following March. According to Mr. Koebele, the time from the laying- 

 of the eggs to the emerging of the adult is, in midsummer, about six 

 weeks. The eggs are broadly ovoid, pale yellowish-green, with a smooth,, 

 delicate shell. After the larvae hatch the empty shells are white and 

 irridescent. They are laid in hemispherical masses, about three-fourths- 

 of an inch across, on the under side of .the leaves, and are unprotected. 

 The masses contain from five hundred to one thousand eggs, which are 

 piled one above another with no attempt at regularity of arrangement. 



The larvae hatch in a few days and immediately begin feeding upon- 

 the epidermis, later eating the whole leaf. They are gregarious, feeding- 

 in colonies until nearly full grown, and when migrating from the leaver 

 ■ or branches they follow one after another in single file. When newly- 

 hatched, the larvae are pale yellowish-green in color, blending very nicely- 

 with the foliage. Later they become a darker green with black mark-
