426 Syrphidae. 



hind margin of third, and at the same time produced less inwards; 

 the abdonien is dull at the base only shining on the hinder half of 

 third and on fourth segment; it is denseiy clothed with long, all pale 

 yellow hairs, as long as the hairs on thorax. Venter greyish black, 

 duUisb, with more or less pale incisures and with long, pale hairs. 

 Legs black, the extreme apex of femora and about the basal third of 

 tibiæ whitish yellow ; hind tibiæ somewhat compressed, slightly curved, 

 hind metatarsi not thickened. Legs haired as usual, with long, dense 

 hairs, the long hairs on femora varying from black to more or less 

 mixed with pale, for the rest the hairs follow the ground colom'. 

 Wings nearly hyaline, with a large, more or less distinct, brown cloud 

 below the stigma, sometimes rather weak or almost wanting. Stigma 

 quite small, nearly quadrate. Alar squamula rather small, blackish 

 brown, the thoracai squamula paler; the fringes yellowish. Halteres 

 yellowish, the knob a little darker, 



Female. Vertex and frons broad, widening downwards, yellowish 

 pruinose and yellow-haired. Abdominal spots much smaller than in 

 the male and generally present only on second segment, sometimes 

 obscure, 



Length 10— 12 mm. 



This species is on account of its long, dense pile somewhat like 

 a Humble-Bee, but less than E. intricarius, from which it is known 

 at once by the not plumose arista and all pale clothing. 



E. anthophorinus is not rare in Denmark but by no means of the 

 most common species; at Copenhagen, Utterslev Mose, Ordrup Mose, 

 Charlottenlund, Ermelund, Dyrehaven, Lyngby Mose, Fure Sø, Ørholm, 

 Geel Skov, Hillerød, Frerslev Hegn, at Sorø; on Lolland at Maribo 

 and in Dødemose west of Nysted; in Jutland at Horsens and Hald 

 near Viborg, and on Bornholm. My dates are 1*^/5—^^/8. It occurs in 

 fens and in thickets and it is interesting that it has quite another 

 behaviour than intricarius, as it never hovers in the air but flies 

 rapidly among low herbage and in bushes. The pupa was taken in 

 Utterslev Mose in April, it developed on ^/s (Schlick). 



Geographical distribution : — Northern Europe, towards the north 

 to northern Sweden, and in Finland ; it is also recorded from Russia 

 at St. Petersburgh, but it seems to have its southern limit in Denmark.
