The Basket-worm — Thyn'dopferyx ephemerceformis. (Country Gentle- 

 man, for August 19, 1880, xlv, p. 535, c. 4 — 15 cm.) 



In reply to information asked of a worm destroying arbor vitas at 

 Bayside, N. Y., a description of the basket, habits of the contained 

 larva, appearance of the male and female moths, and best method of 

 checking the ravages, by hand-picking, are given. 



The Basket or Bag Worm — Thyridopteryx Ephemerseformis. 

 (Country Gentleman, for September 30, 3880, xlv, p. 631, c. 8, 

 4 — 17 cm.) 



Reported as destroying arbor vitas hedges in West Brighton, N.Y. Its 

 food-plants mentioned, present stage of the insect, may be destroyed by 

 insecticides during larval growth, but hand-picking preferable. 



Caterpillars on the Ampelopsis. (Country Gentlieman, for October 7, 

 1880, xlv, p. 647, c. 2, 3 — 16 cm.) 



The moths of the two blue caterpillars of which inquiry is made, are 

 Alypia octomaculata and Eiidryas grata. If the vines attacked by the 

 larvfe are not too large, they may be hand-picked ; if quite large the 

 caterpillars may be killed by showering with hot water from a garden 

 hose.
