48 JOUKNAL OF ECONOMIC ENTOMOLOGY [Vol. 10 



Mr. Prince had a Virginia creeper which was used as a screen and cov- 

 ered the entire end of the piazza, which did not have a leaf on it at 

 this date. The new clusters of fruit on the grape arbors were badly 

 eaten as well as the foliage. 



A great many larvae were collected and brought to the laboratory, 

 but the majority of these did not live. Consequently, more larvae 

 were collected from the same locality on July 28. As Mr. Prince had 

 sprayed everything on his premises with arsenate of lead, which proved 

 to be most effective, it was diflScult to find any living larvse, though 

 plenty were present in adjoining yards. 



All of the arbors within a radius of a mile were in the same general 

 condition. However, outside of this district there was no other com- 

 plaint made in Connecticut. It seems to be a well-established fact 

 that this insect is rarely found in vineyards or arbors located in the 

 country, but only in the city yards. At the Experiment Station farm, 

 located at Mt. Carmel, a grape arbor was inspected several times and 

 no trace of the Eight-Spotted Forester found; neither had there been 

 any complaint from nearby towns such as Yalesville and Meriden 

 where there are several vineyards. 



On August 2, the majority of the larvse collected on July 28 had 

 gone into the sand in the breeding cages. The adult moth will not 

 emerge until spring. The wings are velvety-black and have two large 

 pale yellow spots on the forewings and two smaller white spots on the 

 hind wings. The first and third pair of legs are tufted with orange. 



Two Tachinid parasites emerged August 15, and were identified by 

 Mr. Harrison E. Smith of the Bureau of Entomology as being Win- 

 themia quadripustulata Fabr. It is a question as to whether this in- 

 sect will cause damage in the same locality another year, and also if 

 the parasites will keep it in check. 



The writer has been unable to find any publication which figures 

 the Eight-Spotted Forester as being of much economic importance, 

 and only brief accounts of this insect have been published recently, 

 all of which simply mention it as feeding on grape and Virginia creeper. 

 It seems from the outbreak in New Haven, that considerable damage 

 and financial loss would be caused if this insect became abundant in 

 a commercial vineyard. 



Vice-President G. A. Dean: The next paper will be read by Mr. 

 George G. Becker.
