THE CANADIAN ENTOMOLOGIST.

This species is found on the semi-arid plains of Assiniboia. Its 

 flight is higher and slower than that of any other Trimerotropis I am 

 acquainted with, resembling that of Circotettix, as does also the stridula- 

 tion to some extent, which, however, is no louder than that of most species 

 of its genus. 



In conclusion, I wish to express my sincere thanks to Mr. Scudder 

 for his valuable assistance in determining the material upon which this 

 paper is based.

EULECANIUM LYMANI. 



Sir, — Permit me to correct a slight error into which Mr. King has 

 fallen in regard to the locality where I found the scales of Eulecanium 

 Lymani, as the tree was not, as stated, at Quebec, but at St. Hilare, a 

 station on the line of the Grand Trunk Railway, about twenty-two miles 

 east of Montreal. I shall be happy to send specimens of this scale to 

 anyone interested in scale insects. H. H. Lyman.
