Genera a7id Species of Blood-sucking Muscidse. 295 



blackish hair on dorsum of fourth segment long and fine. 

 SquamiM : thoracal squama brown. Halteres buff. 



India : type and one other specimen from Mussoorie, 

 United ProVmces, September 1906 {F. M. Howlett). 



This is a very distinct species, which, while resembling the 

 foregoing in size, is at once distinguishable by the dusky 

 coloration of the body and legs, by the sides of the front 

 being scarcely visible except anteriorly, and by the remark- 

 able row of hairs on the inside of the first joint of the front 

 tarsus. Owing to the latter character St. 'pulla ^ presents 

 Kome slight approximation to the ^ of the African St. omega, 

 Newst., in which, however, the row of hairs on the inside of 

 the front tarsus extends to the end of the second joint, while 

 the hairs themselves are much longer and conspicuously 

 curled. 



Musciy^. 



Phil^matomyia*, gen. nov. 



Greyish flies, not unlike Musca domestica, Linn., in general 

 appearance, but distinguishable at once owing to the remarkable 

 proboscis. — Front in (^ narrow, its ividth in centre being from, 

 one-eleventh to one-fifteenth of total width of head ; width of 

 front in ? at vertex one-third of total ividth of head ; proximal 

 portion of proboscis (inenlum) a strongly swollen chitinous bulb, 

 distal portion soft and fleshy, folded back under distal end of 

 bulb when not in use, but ivhen in use extended, its terminal 

 section consisting of a " tubular extension,^' which is pro- 

 truded from between the labella, and is surrounded at the distal 

 extremity with a circlet of stout chitinous teeth; venation 

 generally as in Musca domestica. 



Head: arista feathered as in Musca domestica] palpi 

 slender, cylindrical, slightly thickened at tips ; proboscis 

 when not in use can be entirely retracted within buccal 

 cavity, so as to be invisible when head is viewed in profile, 

 but, in dead specimens at any rate, more usually protrudes, 

 projecting downwards at an angle of about 45° ; the bulb is 

 pjlished and bears scattered hairs. When the fleshy distal 

 portion is reflexed beneath distal end of bulb, the extremity 

 of the proboscis has a pointed appearance ; the fleshy portion, 

 like the bulb, bears fine hairs; when retlexed, the fleshy 

 portion ends in the lamella, which therefore come to lie 

 between the pointed tip of the proboscis and the rounded 

 ba^e of the bulb, and, when the proboscis in this condition is
