The larger fpecimen of this infect I purchafed, as Englilh, at a 

 (hop in Piccadilly; but the fmall one (which I believe to be the 

 male) I took upon the funny bank of a fandy ditch near Martlelham 

 Heath, at the fame time with A. affinis, I think that I have 

 likewife feen it in the rich cabinet of our Secretary, my tutor in 

 Entomology, and to whofe liberality mine is indebted for fome of its 

 raolt valuable contents. 



This infect is beyond a doubt the Sphex arenaria of Fabricius, and 

 likewife the S. hirfuta of Scopoli and Schrank; although Gmclin 

 and Villars make them different. It is clearly diftincl from the 

 two preceding fpecies. Its wings of the length of the body, tipped 

 with a black nebula; its abdomen of a figure inclining to ovate; its 

 large head very villofe, as well as its trunk ; its maxillse threatening 

 with an immenfe acumen, plainly prove this. It is larger alfo in 

 all its parts; the band which furrounds its abdomen is of a brighter 

 red; the legs are much more briftly, efpecially the tarfi; and the in- 

 terior fpine, which arms the apex of each of the pofterior tibia?, is 

 more confpicuouily pectinated.
