H. PATIYA, sp. n. 



$ . Nigra nitida, ahdomine pallide-ca-sio tomentoxo, linea nigra dorsali signato, 

 Ocnli magni nt(di arete contigui ; alee stth-brunescenies venis transversis appropin- 

 quis, apiceque vena longittidinalis quartce leviter recurvo ; halteres nigri. Femora 

 antica unidentata ; tibiixque anticis excaratis. Long., 3 mm. 



Head : forehead flat, epistome sliglitly prominent ; eyes large and bare, closely 

 and deeply contiguous ; antcnnre short and grey, surmounted by a snowy-white 

 triangular spot ; arista almost bare ; palpi black. r/zor^.T shining black, with hoary 

 spots on the shoulders, and four medio-central dorsal bristles behind the suture. 

 Scutellum bright black. 



Abdomen oval, and tapering towards the apex, which is pointed, with small 

 subanal processes ; colour, light bluish-grey with the first segment black, second, 

 third and fourth segments marked on the dorsum with a longitudinal black stripe, 

 which, tolerably wide at first, narrows towards the apex. 



Wings pale brown, transverse veins rather near together, the internal one being 

 placed over the discoidal cell nearly two-thirds from its base ; fourth longitudinal 

 vein curved upwards a little at its extremity. Calgptra sub-fuscous. Halteres 

 nigrescent. 



Leffs black, fore femora with one short sharp tooth on the under-side near the 

 end, and also with a blunt hairy tubercle placed a little behind and on the inner side 

 of the tooth i fore tibice deeply indented at the base, and a little thickened along 

 their front half. Middle femora with two long blunt spines beneath their base ; 

 middle tibise with two bristles on the inner sides near the middle ; hind femora a 

 little curved, having a row of hairs of nearly equal lengths along their outer sides 

 as well as on the basal halves of their inner surfaces, which are then bai'e to near the 

 end, where three or four bristles are placed ; hind tibiae with a few long bristles on 

 their outer and anterior surfaces, and with a number of short adpressed hairs on 

 their inner extremities. 



I found a single male of this little fly, which is peculiar by being much smaller 

 than any other that I know in this genus, in an osier bed near Buckingham in 

 August, 1887. It seems closely allied to the Musca glabrieula of Falle'n, and may 

 possibly be identical with it ; but his description is very short, and neither he, 

 Meigen, nor Zetterstedt mention the colour of the abdomen, but indicate that the 

 whole insect is black, so I have decided to describe it as a new species, and give a 

 somewhat full diagnosis. 



The H.Jloralis of R. Desvoidy is given as a synonym of H. glabrieula, but he 

 only described the female, and I have not seen that sex of H. parva.

 In my last Supplement I omitted to recoi'd the occurrence of this species in
