larva fccdin<,r on the young bark lice, while from the puparium of this larva 

 she reartxl another ChalcitI, which she identitied as a species of Eiilophus. 

 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 ii s b i v u 1 - 

 neriis Muls., and Anatis ocel lata Oliv., were observed by her feeding 

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

 A syrpiiitl tly, Haccha fascipennis W'ied, was reared liy Dr llo])kins 

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

 a species of Pachy neuron, which lie thinks may possibly be the insect 

 referred to Kulophus b\- Miss Smith. Ihi; larxac of llyj^eraspis 

 s i g n a t a were also observctl feeding on specimens from Massachusetts. 



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

 cation of such contact insecticides as a whaU? 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 e.xperiment 

 that a wash composed of 3 gallons of wati-r, ' ii pouml of hellebore and i 

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



spring, was effectual.

Cockscomb elm gall 

 Colopha ulviicola Fitch 

 Tiie leaves of the .Vmerican elms are not infreijuently more or less deformed by a 

 peculiar cockscomh-like gall whicli ajjpears 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 cjuite 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, ami on s|)reading these apart, a glossy olive brown plant
