HYMENOPTERA. 



Genus 13. PARASPHEX. 



26? 



Enoilia, Dahlb. Hym. Europ. i. 28 (1843), nee Hiibn. Lepidop. 



(1816). 



This genus is distinguished from Sphex proper by having the 

 elaws of the tarsi tridenticulate ; the body is of a more slender 

 and graceful form ; the abdomen is more elongate and narrow, 

 and very acute or lanceolate at the apex. It forms a distinct 

 subgeneric division of the typical Sphex.

 pubescens of Fabricius.
