1914-] S. p. Agharkar : A New Species of Blepharocerid Fly. 161 



Genitalia (figs. 1-2) very conspicuous. & The hypopygium 

 is during life bent upwards very much like the forceps of an 

 earwig ; there is a small dorsal plate covering only the basal parts 

 of the genitalia. A much larger ventral plate with its sides turned 

 upwards so as to enclose the genitalia from below and the sides is 

 present. Its posterior edge has a wide shallow notch in the 

 middle. From near the sides of this notch arise two leaf-like 

 claspers which are folded in the middle along their length. They 

 bend towards each other and meet nearly in the middle line. From 

 the sides of the ventral plate, a little behind these claspers arise a 

 pair of stiff three-lobed claspers. During life the}' are apparently 

 turned towards each other so that one of the lobes of one meeti 

 the corresponding lobe of the other enclosing an arched surface 

 between. Arising from the anterior part of the ventral plate are 

 two beak-headed claspers, with their beaks turned towards one 

 another and enclosing a space through which the penis is protruded. 

 The penis is not visible in all specimens, but where it is seen it 

 appears to be a cylindrical structure from which eight fine 

 filamentous structures arise.' These appear to be the actual intro- 

 mittent organs. 



$ The genitalia of the female are neither so conspicuous nor 

 so complicated as those of the & . There is a dorsal and a ventral 

 plate similar to that of the cf but much smaller. There is a pair of 

 leaf-like claspers situated similarly to the claspers of the male but 

 much smaller. The only other organs are a pair of small leaf-like 

 claspers arising from near the middle of the anterior edge of the 

 ventral plate. These guard the $ genital aperture. 



Legs long and slender. The legs of the cf are proportionately 

 much larger than those of the female. Colour of legs in a* brown, 

 in the $ yellowish- white. Front tibiae without any spurs, the middle 

 ones with a single terminal spur, the hind ones with a small spur in 

 addition to and by the side of the terminal spur. Ungues pointed 

 and hook-like. Pulvilli absent, empodia rudimentary. 



Wings (fig. 3). The venation can be distinguished from that 

 of other species of Philorus by the following characters : (i) the 2nd 

 vein is bent upwards instead of downwards near its termination ; 

 (2) the forking of the 5th and 6th veins takes place at about ^ its 

 length from the base. 



Halteres well-developed; both stem and club light brown in 

 colour. 



Immature stages unknown ; it is possible that one of the three 

 species of larvae found occurring with it may belong to it. But 

 nothing can be said on this point until more information is avail- 

 able. 



Length cf 4. to 5 mm. 2 5'5 to 6 mm. Described from gcf'and 

 5 9 specimens, collected by Mr. Bion at Nagaberan, Kashmir. 



Types preserved in the Indian Museum. 



' Fig. I, 2 does not show the parts in their natural positions ; it was drawn 

 trom a balsam preparation in which the parts had been pressed out flat.
