Wandering Larvae of Pyrrharctia Isabella (Lep.). 



On October 31, 1901, at Blacksburg, Virginia, the larvae of this 

 species were common, wandering about over the ground as is their 

 habit before winter arrives ; one was observed as late as December 7, 

 while on December 28, 1901, at Annapolis, Maryland, again a few 

 were observed. On the i8th of January, 1902, at Blacksburg, a hiber- 

 nating larva was found while in April 6 following, in the same lo- 

 cality, a full-grown larva was found. In the Maryland locality, wan- 

 dering was observed as early as September 13 (1901). 



Carpocapsa pomonella Linnaeus (Lep.). 



The adults of this species were emerging at Annapolis, Maryland, 

 in 1901, about May n, from overwintered pupae. 



Harrisina americana, the American Procris (Lep.). 



A colony of the larvae of this species obtained from a correspondent 

 in Virginia by Professor William B. Alwood pupated at Blacksburg 

 on July 22 (average), the moths emerging on August 3 following. The 

 larvae were on cultivated grape. At Annapolis, Maryland, the same 

 year, a colony about half grown were taken from grape on September

The Method of "Worming" for the Peach Borer Sanninoidea 



exitiosa Say (Lep.). 



While engaged in studying this insect for the national Bureau of 

 Entomology in Georgia in 1906, I observed a variety of methods in 

 practice for the purpose of removing the larvae from the trees, but 

 they all seemed to me to be doing more harm than necessary to the 

 trees, at the same time not proving very efficient. I remember dis- 

 tinctly following several different gangs engaged in the operation and 

 obtaining from the treated trees nearly as many of the caterpillars as 

 would be obtained from a like number of untreated trees at the same 

 place. Many of the trees, moreover, had been badly wounded without, 

 it appeared, the compensating destruction of the larvae. Whether the 

 Bureau has a note to the effect or not I am uncertain, so that while 

 thinking of it take this opportunity of recording my mental impres- 

 sion of the correct procedure without, I hope, seeming to infringe upon 

 the rights of the Department of Agriculture. By trial. I have repeat- 

 edly satisfied myself that locating the larva and removing it is a com- 

 paratively simple matter and one to be learned easily from experience 

 by any close observer and that it would be economical for large or- 

 chardists to employ one unusually bright workman for this purpose 

 alone throughout the whole year rather than as is done now to have 

 gangs of a half dozen or more stupid ones, employed irregularly and 

 when working chiefly occupied in half-girdling the trees and killing 

 earthworms. To locate a larva but one cut of the knife is necessary 

 and this cut should also kill it. The correct method is rapid, sure and
