 beneath. Thorax, the pubescence sparing and griseous on the 

 disk, but dense, long, and white at the sides of the metathorax ; 

 wings subhyaline and iridescent, the nervures ferruginous ; the 

 floceus white, the scopa bright fulvous, the posterior tibise and tarsi 

 and the apical joints of the anterior and posterior pairs rufo-fulvous. 

 Abdomen shining, ovate, and having a short white marginal fringe

Male. Length 3^- lines. — The clypeus white and having three mi- 

 nute fuscous dots placed in a triangle, the anterior dot sometimes 

 nearly obsolete, densely covered with long white pubescence ; along 

 the margins of the eyes and at the insertion of the antennae a little 

 mixture of fuscous pubescence. Thorax shining, and having a thin 

 griseous pubescence, mixed with fuscous hairs at the margin of the 

 scutellum ; wings subhyaline, iridescent, the nervures testaceous ; 

 the tarsi ferruginous. Abdomen lanceolate, shining, and delicately 

 punctured, the margins of the intermediate segments depressed, 

 smooth, and shining, sometimes having a loose fringe of pale 

 pubescence ; the extreme apex ferruginous. B.M. 



Taken at Weybridge once in July. Evidently very rare in the 

 west of England, but very abundant in some situations in the north. 

 Several specimens were taken near Wakefield at the beginning of 

 August. Mr. Hardy found the species very common in Penmanshiel 

 Wood, Berwickshire, throwing up its little hillocks at the sides of 

 pathways. It has also been received from Ireland. Eabricius 

 describes an A. analis in his ' Systema Piezatorum ; ' but it cannot be 

 the same species as Panzer's if he described it correctly. He says, 

 "anus rufus;" in the insect described by Panzer we read, " seg- 

 mentis apice fuscescentibus."
