320 ENTOMOLOGICAL NEWS. [Nov. , '06 



but Dr. Lintner considered it to be the work of Steganoptycha 

 claypoliana, which he reported as attacking maples in Penn- 

 sylvania, from specimens sent to The Country Gentleman in 

 1895. t From the account of the correspondent I should pro- 

 nounce the injury that of the maple leaf stem borer or sawfly, 

 but if Dr. Lintner really obtained the adult and found it a 

 moth, the report must be accepted as authentic. 



In corresponding about the matter, Dr. E. P. Felt states 

 that he finds no records or specimens in the New York State 

 Museum, which indicate that adults were actually reared from 

 the leaves by Dr. Lintner. 



It is quite certain that Prof. J. B. Smith observed the same 

 insect in New Jersey in 1901,$ or two years after it was first 

 noticed in Connecticut, but had not been able to obtain the 

 adults in I903.§ 



Parasites. 



It has been mentioned that. parasites were reared from this 

 sawfly. Several specimens of Anoplius canadensis Ashm. were 

 obtained from the breeding cages. At first these were thought 

 to be parasitic upon the sawfly, but as the insects of this genus 

 parasitize diptera only, so far as is known, they may have 

 attacked a dipterous parasite of the Priorphorus. A dipterous 

 larva was noticed, and doubtless many more occurred in the 

 material. A chalcidid parasite resembling Pteromalus was 

 reared from the breeding cages, one specimen only being ob- 

 tained. 



Remedies. 



No experiments have been made with remedies against this 

 insect, but a knowledge of its life history enables one to sug- 

 gest a possible treatment. Spraying the ground under the 

 tree with kerosene emulsion about June 15th, when the insects 

 are going into the soil, will doubtless destroy the larvae ; or if 

 the land be not in turf, cultivation of the ground at this time 

 is certain to kill many of them. As the insect is so hard to rear, 

 there should be no difficulty in controlling it.
