PLATE LXV. 
ILLUSTRATIONS OF SOME GENERA OF FOSSORIAL HYMENOPTEROUS 
INSECTS, BELONGING TO THE FAMILY SPHEGID. 
Tue curious genus Chlorion of Latreille, (Ampulex Jurine) hay- 
ing been raised by Shuckard* and Dahlbom + to the rank of a 
family, distinct from the Sphegidze, 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 Entomologi- 
eal 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. 
Genus.—CHLORION, Latreille.t (AMPULEX Jurine.) 
CHLORION PURPUREUM, Westw. 
(Plate 65, fig. 1.) 
C. lete purpureum, valde punctatum, mesonoto obscuriore, metanoto transverse striato, carinis- 
que novem (2da et 3tia utrinque a medio discretis) antennis clypeo tibiis tarsisque nigris ; 
alis anticis fuscis fascia lata pone medium alisque posticis sub-hyalinis ; abdomine postice 
minus compresso quam in A. compressiventre Guer.; collare postice tuberculo elevato 
instructo ; mandibnlis nigris apice piceis; tarsorum articulo penultimo minori quam in 
congeneribus, articulo basali antennarum subtus rufescenti. 9

Habitat in Africa Australiori, D. Burchell. 
In addition to this species and the original type of the genus 
Chlorion compressum, the following species have been recently 
described and figured. 
Species 3.—CHLORION CYANIPES, Westw. (In Trans. Ent. Soc. 3, p. 230.) 
From the Cape of Good Hope.

Dolichurus is removed to the family Pompilidze, whilst in his previous § Dispositio methodica’, 
Part 1, Lund. 1842, he has placed Ampulex and Dolichurus together as the first section A. of 
Pompilidee.
