DESCRIPTIONS OP PIYE SPECIES OF ACULEATE STMENOPTEEA 

 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 Pomp Hides new to our list, and 

 I deferred describing them fdly 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 Eev. H. S. 

 G-orham. A description of this species follows those of the Pompilidce. 



1. Pompilus minutulus, Dahlbm., Dispos., 1842, p. 10. 

 = neglectus, Dahlbm. ? 

 = cellularis, Thorns. 



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. 



Pace, below the antennae, sides of the thorax, the metathorax, and 

 coxae, covered with silvery pubescence ; prothorax sharply emarginate 

 posteriorly, wings with a broad, fuscous, apical band ; 3rd submarginal 

 cell triangular. $ with the posterior tibiae sinuate on the side towards 

 the body, and incrassated at the apex. 2 with the anterior tarsi simply tibia of 

 spinose, not pectinated as ra most of the species. Length, 8 — 9 mill. tulus 6 - 



This species exactly resembles gibhus 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 I 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 <J , and also a 9 .
