and behind, femora and tibiæ yellow, the hind ones blackish at the 

 apex; anterior tarsi yellow, more or less brown towards the end, the 

 front tarsi generally only on the last joint; hind tarsi black. The 

 femora mainly short-haired ; the front metatarsi bristly below almost 

 as in the male, and the hind metatarsi likewise a little spinulous. 



Length 4,8 — 5,5 mm. 



A. auricollis is rare in Denmark, I only know eight specimens, 

 and it was first taken in 1883; at Svenstrup between Roskilde and 

 Ringsted and at Faxe Ladeplads; on Funen at Odense, and in Jut- 

 land in Greisdalen and Højenbæk Dal at Vejle (H. J. Hansen, the 

 author). The dates are in July and August. It was taken in low 

 herbage on humid piaces. — Kowarz uses the same terms in describing 

 frons and epistoma as for confinis; I find the frons greenish white 

 and only black when seen from in front and below; the epistoma is 

 silvery white when seen more or less from above; only when seen 

 just from in front or from below it is black; it is thus more white 

 than in confinis, where it is whitish only when seen quite from above. 



Geographical distribution : — Europe down into Italy ; towards 

 the north to middle Sweden.
