Insects from Infested Twigs. 



"While at Dr. Leconte's library in the spring of tins year, tliis 

 distinguished entomologist showed me some boxes of infested twigs, 

 pointing out the value of information to be thus gained, viz., the 

 kinds of trees and bushes infested by various insects, the time of the 

 year in which they make their appearance, the length of time they 

 need for their transformation, their natural enemies, hatching from 

 them (Ichneumonidto), etc. Of course each kind of wood must be 

 kept in a separate box. 



Besides this very interesting information, for which a diary should 

 be kept, I do not know of a more convenient and paying method of 

 getting good specimens for the collection and for exchange. In one 

 box, for instance, filled with pieces of a dead wild-grapevine, I took, 

 from May 2d to May 23d, fifty-four specimens of Phymatodes amoenus, 

 by no means a common insect; about a dozen Sinoxylon basilare, from 

 May 14th to June 3d; one specimen of Ichnea laticornis, May 5th, and 

 two, May 13th. Out of a box of hickory twigs, during the month of 

 May, I obtained ten specimens of Anthaxia viridicornis and a number 

 of specimens of Leptostylus and Sternidius. The insects, when they 

 emerge, crawl to the top or under the cover of the box, and are thus 

 easily seen. In my opinion the wood should be occasionally moist- 

 ened. Whoever will try this " wood-chamber " breeding will find it 

 a very interesting pastime — but please keep correct notes, and give 

 them to the entomological public.
