rOctober, 



black ; fiioe and epistome wliite ; palpi loii^, filiform, and whitfi ; tliorax gi-ey, with 

 Bub-distinct brown stripes ; abdomen grey and immaculate ; wings grey ; legs dark 

 grey, with apices of femora mostly rufous, as well as the bases (with the coxae) of 

 the middle ones ; tibiae and tarsi testaceous and piceous ; hind tibiae spinose. 

 Length, 6 mm. Common on the sea coast. 



I believe that the 5. declpiens, Hal, must be a variety of this species ; Haliday 

 says that it has the head broader, but he gives no other distinctive character. 



Sp. 17. — S. VILLIPES, Ztt. 



This species closely resembles the last, but is rather larger, and much more 

 hairy ; it also differs by having the two basal joints of the antennae rufous ; the 

 palpi clavate ; the abdomen narrower, with a red apex, and covered like the thorax 

 with long grey hairs ; the legs are coloured like those of <S. litorea, but are much 

 more villose. Length, 7 ram. Rare. 



Sp. 18.— S. nuDis, Hal. 



This species, taken in Ireland by Haliday, is thus briefly described by Curtis :* 

 " Obscui-ely cinereous ; thorax lineated ; hypostoma and tibise ferruginous ; abdomen 

 of male clothed with yellow hairs." 



•Gen. XIII.— THTEEOPHORA, Latr. 



Gen. ch. — Head sub-trigonal ; eyes small, round, and nude ; face 

 very oblique, antennjB short, with bare arista ; oral setge several in 

 number; proboscis long, with large lobes; palpi sub-clavate ; thorax 

 with rows of dorsal bristles ; scutellum very long in the male, with 

 the end truncate, and furnished at each angle with a long strong 

 spine, short and triangular in the female ; abdomen short ; wings 

 without the auxiliary vein ; legs long and hairy. 



Sp. 1. — T. FUECATA, F. 



Head reddish-brown ; face shining yellow ; frontalia with a black spot upon the 

 vertex ; antennae reddish-brown, with the third joint oval, and arista thickened to 

 the middle; thorax bluish-grey, indistinctly striped; scutellum of male half the 

 length of the abdomen, with the first half slate-coloured, and the hinder part red ; 

 abdomen dark brown, with the anal segments sometimes rufous ; wings flavescent ; 

 legs testaceous, robust, and very hairy. The whole fly is villous, the hairs on the 

 abdomen being almost woolly. Length, 6 mm. Very rare. Found by the Rev. 

 L. Jenyns near Ely. 



This peculiar fly is very abnormal. It differs from all others in this family by 

 the shape of the head and scutellum, as well as by the want of the auxiliary vein.
