150 UNDESCRIBED SPECIES OF MUSCIDjE. 



are longer and curved, nearly naked inside, but with a few long 

 hairs scattered on the outside. 



This species is much more common than M. hortorum, about 

 Holywood. 



Trie. — Anthomyzid^, Latr. 

 Gen. — Anthomyia, Meig. 

 Subgen. — Fannia, Rob. D. 



Sp. A. F. aprica. Cinerea pedibus posterioribus testaceis. 



Except in colour, agrees with A. F. rufipes d (Fall. Muse. p. 84, 

 No. 3.) The thorax and abdomen are cinereous ; the impressions 

 of the latter in the male produce, in some lights, a band of tri- 

 angular dark spots. The face and orbits are silvery in the male, 

 duller white in the female ; the frontals, antenna, and palpi, 

 black. The wings obscure, their base, with the calyptra and 

 poisers, yellow. The fore-legs almost black in the male ; in the 

 female the thighs are testaceous at the base and tip. The thighs 

 and shanks of the other legs are testaceous ; the structure of the 

 middle pair exactly as in A. F. rufipes. 

 At Holywood ; in sunny places ; not common. 



Note. — The subgenus Fannia may be distributed in the following 

 sections. 



A. Legs rufous. — A. ornata, rufipes, aprica. 

 A A. Legs black. 



B. Thorax streaked. — A. scalaris, lepida. 

 BB. Thorax black. — A. manicata, armata, eye. 



I can see no sufficient cause for regarding the subgenus 

 Philinta (Rob. D.) as distinct from Fannia. 



II. ACALYPTERATI. 



Tkib. — Scatomyzibve, Fallen. 

 Gen. — Cordylura, Fallen. 

 Subgen. — Delina, Rob. D. 



Sp. C. D. flava. Flava alls hyalinis. 



Yellow, with hyaline wings : a dot on the vertex and the occiput 



d Described by Macquart (S. a B. II. 312, No. 10) under the name of Limno- 

 ■phora hamata. I have received it from F. Walker, Esq.
