DESCRIPTIONS OF FIVE SPECIES OF ACULEATE HYMEN 0 PEER A 
UNRECORDED AS BRITISH. 
BY EDWARD SAUNDERS, F.L.S. 
In the August number of this magazine I mentioned that I had 
captured at Chobham three species of Pompilidce new to our list, and 
I deferred describing them fully until I could have an opportunity of 
examining them more carefully. I now offer the descriptions of these, 
and also that of a fourth species, of which I took a $ , two years ago, 
at Chobham, and two $ this year. 
During my stay at Chobham, I also caught two $ of a species of 
Andrena * which I did not recognise, flying about the heather : these 
prove to be £ of lucens , Imhoff, a very distinct species, and also an 
addition to our fauna. I find in my collection another specimen of 
the same species, without note of locality, given to me by the Dev. H. S. 
Gorham. A description of this species follows those of the Pompilidce. 
1. Pomp it us minutulus , Dahlbm., Dispos., 1842, p. 10. 
= neglectus , Dahlbm. ? 
= cellularis , Thoms. 
Black, the two basal segments of the abdomen, and the base of the 3rd red ; 
the apex of the 2nd segment in the $ sometimes more or less fuscous. >. 
Face, below the antennae, sides of the thorax, the metathorax, and J 
coxae, covered with silvery pubescence ; prothorax sharply emarginate ' \ 
posteriorly, wings with a broad, fuscous, apical band ; 3rd submarginal yn 
cell triangular. £ with the posterior tibiae sinuate on the side towards 
. _ Posterior 
the body, and incrassated at the apex. $ with the anterior tarsi simply tibia of 
• • • P. 7)1X71 IL- 
spxnose, not pectinated as in most of the species. Length, 8 — 9 mill. tutus <$ . 
This species exactly resembles gibbus in general appearance, but 
the shape of the posterior tibiae of the £ and of the anterior tarsi of 
the 9 readily distinguish it. 
Thomson calls this species cellularis , Dahlb., and refers Dahl- 
bom’s neglectus to spissus ; he may be right as to neglectus , of which 
Dahlbom says, “ cellula cubitalis 3ia late trapezina,” a character 
belonging to spissus , and not to this species, but 1 cannot think that 
he is right in referring our species to cellularis, Dahlb., of which the 
author says: “cellula cubitalis 3ia minuta triangularis petiolata, 
corpus parvum £ valvula analis et segmenta ventralia ut in £ pectini- 
pede, at valvula major et apice barbatula.” 
"Wesmael, who, like Thomson, describes the present species most 
* Since writing the above, I have been again to Chobham, and succeeded in obtaining 
another , and also a $ .
