PLATE LXV. 
ILLUSTRATIONS OF SOME GENERA OF FOSSORIAL HYMENOPTEROUS 
TNvSECTS, BELONGING TO THE FAMILY SPHKGID.E, 
The curious genus Chlorion of Latreille, (Ampulex Jitrine) hav¬ 
ing been raised by Shuckard * and Dahlbom f to the rank of a 
family, distinct from the Sphegidje, it becomes interesting to 
examine its precise structure, as well as that of some new forms 
closely allied to it ; in order to discover the propriety of such a 
step. In the third volume of the Transactions of the Entomolom- 
cal Society, I established two new genera, bearing such a relation¬ 
ship ; but, it happened, that at that period I was acquainted only 
with one sex of each of them. Having since become acquainted 
with the opposite sexes of each, and having likewise observed in 
the Collection of the British Museum another undescribed form, I 
have in the accompanying plate completed my illustrations of these 
groups, by figuring the sexes hitherto wanting, as well as numerous 
details of the genus Chlorion itself, together with a new and beautiful 
species of that genus from the Collection of W. Burchell, Esq.

In addition to this species and the original type of the genus 
Chlorion compressurn, the following species have been recently 
described and figured.
