ANNOTATED LIST OF BRITISH ANTHOMYIIB^. 



BY K. ir. MEADK. 



(continued from page 126.) 



8. DETMEIA, Meig. 

 Gen. cJi. — Eyes bare, sub-contiguous in males ; antennse sliort, 

 . witli 8ub-pluiin)se arista ; peristome and cheeks bristly ; proboscis 

 elongate, horny, and with a moveable, pointed, hook-like apex ; abdo- 

 men oblong and hairy ; alulets moderately developed, with unequal 

 scales ; wings with anal vein not prolonged to the margin; legs spinous. 



D. HAMATA, Fall. 



ohscura, Meig. and Macq. 

 Of this peculiar genus with its elongated hooked proboscis, only one European 

 species is known. I am not aware whether any exotic species have been described, 

 but in a collection of North American AnthomyiidcE, which I received in 187() fi'om 

 the Museum of Natural History', in Cambridge, Mass., for inspection, through the 

 kindness of Baron E. Osten-Sacken, I found several specimens of a species closely 

 related to D. hamala, but rather smaller. 



9. POGONOMTIA, Eond. 

 Gen. eh.- — Eyes bare, sub-contiguous in males ; antennae short, 

 second joint armed with long bristles ; arista sub-pubescent ; peristome 

 thickly bearded with bristles ; proboscis of ordinary form ; abdomen 

 oblong, and hairy in the males, especially at the apex ; alulets of mo- 

 derate size, with unequal scales ; wings with anal vein not reaching the 

 margin ; legs bristly. 



P. ALPicoLA, Eond. 

 Kondani formed this genus for a single alpine species, which bears a strong general 

 resemblance to Drymeia hamala, but differs essentially from that fly by the absence 

 of the hooked proboscis. P. alpicola is shining black, about 3 lines in length, with 

 fuscous wings, black poisers, hairy body and legs. Rondani only knew the male ; 

 the female differs from it in having the eyes separated by a frontal s^pace, occupying 

 nearly a third of the width of the head ; this space is of a deep velvety black 

 colour, bordered on each side by a narrow whitish margin, in which is seated a single 

 row of strong bristles, extending to the base of the antennse. The ocelli are seated 

 on an oval spot, the front part of which glistens with silvery-white reflections; 

 there is also a wcll-mai-ked, triangular, silvery-white spot between and over the bases 

 of the antenna; (this spot also exists in the male, though of a smaller size). The 

 peristome is nearly smooth, and the body and legs less hairy than in the male. The 

 abdomen is conical and pointed at the apex. The colour is shining black, with cine- 

 reous reflections. The poisers arc black, and the wings fuscous, but less deeply 

 coloured than in the male, especially at their bases.
