larva feeding on the young bark lice, while from the puparium of this larva 

 she reared another Chalcid, which she identified as a species of Eulophus. 

 Three lady beetles, H y p e r a s p i s s i g n a t a Oliv., C h i 1 o c o r u s b i v u 1 - 

 nerus Muls., and Anatis o c e 1 1 at a Oliv., were observed by her feedino- 

 on the bark lice, and a species of Chrysopa was engaged in the same work. 

 A syrphid fly, B a c c h a f a s c i p e n n i s Wied, was reared by Dr Hopkins 

 from Massachusetts specimens and from the puparium of this tly he obtained 

 a species of P a c h y n e u r o n, which he thinks may possibly be the insect 

 referred to Eulophus by Miss Smith. The larvae of Hype rasp is 

 signata were also observed feeding on specimens from iMassachusetts. 



Remedial measures. This insect could be easily controlled by an appli- 

 cation of such contact insecticides as a whale oil solution or a kerosene 

 emulsion. The treatment will be more effective if performed at the time 

 when most of the young are crawling. Miss Smith found by experiment 

 that a wash composed of 3 gallons of water, ig pound of hellebore and i 

 teaspoonful of carbolic acid, put on with a whitewash brush during the early 



spring, was effectual.

Cockscomb elm gall 

 ColopJia iclinico/a Fitch 



The leaves of the American elms are not infrequently more or less deformed by a 

 peculiar cockscomb-like gall which appears in June, and is the work of a small aphid 

 or plant louse. 



This interesting gall is a very common one in the vicinity of Albany, 

 and occasionally is quite abundant. It is sometimes so numerous as to pro- 

 duce very serious deformations of the leaves, and a corresponding injury. 

 The young galls appear about the first of May as slightly elevated ridges 

 on the upper side of the leaf. Soon after, on the opposite side, elongated 

 openings appear, and on spreading these apart, a glossy olive brown plant
