SUPPLEMENT. 



Since the pages containing the Andrenulx were published, 

 the following three additional species have been described 

 as British, two by Mr. R. C. L. Perkins, and one by 

 myself, in the Entomologists' Monthly Magazine, vol. xxxi. 

 pp. 39 and 258. 



Sphecodes rubicundus, v. Eag.—"S head and thorax 

 closely punctured, and rather densely clothed with grey 

 hairs, much as in pilifrons ; antenna3 rather short, the 

 joints much swollen in front, with very narrow basal 

 pubescent rings, fourth joint hardly longer than the second 

 and third together, and subequal to the fourth, the follow- 

 ing joints almost as wide as long ; abdomen suboval, 

 unusually wide for that of a (J, and formed more like that 

 oiferruginatus, the basal and second segment entirely red, 

 the third more or less black at the apex, basal segment 

 largely and somewhat remotely punctured, the following 

 segments more closely so, lacinia of the armature produced 

 into a single spoon-shaped process, quite uulike that of any 

 other British species ; second subniarginal cell almost as 

 wide at the base as high, wing hooks five to seven. ? 

 closely resembles that sex oi spiiiulosiis and pilifrons by the 

 close puncturation and hairiness of the mesouotum, but may 

 be known from the former by the coarser puncturation of 

 the head, the shorter antennas, the joints of the flagellum 

 of which are wider than long, and by the smaller number 

 of its alar hooks, 5-7 instead of 9-10; from the latter 

 (S. pilifrona) it may be known by the red colour of the 

 abdomen extending almost to the apex, the fifth segment
