The present insect is an aberrant member of the subgenus Allo- 

 nemobius, typical individuals of which may be distinguished from the 

 other species by the proportionately longer ovipositor, which usually 

 exceeds the length of the caudal femur by about 

 one-quarter, the more grayish general coloration 

 and the distinctive coloration and marking of the 

 head which is deep shining piceous below the 

 antennae, and grayish or brownish gray above, 

 with two or three usually distinct dark narrow 

 longitudinal stripes on the occiput. 



Described from twelve males and thirteen 

 females from three localities. 



Single type here designated: 9 ; High Park, 



Toronto, Ontario. On sandy soil. September 8, 



1902. (E. M. Walker.) [University of Toronto
