it ends in a very sharp raised ridge extending to the an- 

 tennal cap ; the boundary is formed by two darkened 

 furrows bordered interiorly by two or tliree smaller parallel 

 furrows ; the frons itself (along eye-margins exteriorly to 

 the triangle) has two very deep and broad furrows extending 

 along the sides of the triangle from the vertex to end of the 

 triangle ; the minute ])airs of vertical bristles stand at the 

 beginning of these furrows. Ocelli brown, with tiny ocellars 

 each side of the front ocellus. The hind head is darkened 

 behind the ocellar triangle except along the actual vertex, 

 ■which is yellow in tw o long confluent spots ; the rest of 

 hind head is brownish yellow. 



Side-view : — The eyes are larger than usual, nearly circular, 

 though slightly longer horizontally than vertically ; the 

 frons is hence less prominent than usual, the distance from 

 antennal base to eye-margin being about 03 of the hori- 

 zontal eye-breadth ; the profile is less triangular than 

 usual, there being well-marked horizontal jowls of abou,t ^ 

 the eye-depth running into the frons by a concave face-line. 

 The side is all brown-yellow except that the frons is there 

 infuscate. Antennae black, small 2nd joint, 3rd elliptical ; 

 arista pale, but brown on the swollen basal joint. The pale 

 face has a slight central swelling below anteunse. Palpi 

 orange. 



Thorax discally grey ; two mid-stripes darker, extending 

 from front to back, just separated till towards the scutellum, 

 where they meet; alongside these stripes is an interrupted 

 dark stripe forming a spot about the position of the cross- 

 suture, and a longer continuing stripe extending to the 

 scutellum ; just above the side-suture is a similarly broken 

 indistinct line ; callus and pleura dull orange-brown. Scu- 

 tellum orange, swollen, rounded in profile, hairy, especially 

 on the margins, though no true bristles are present ; it is 

 darkened discally, with the orange showing through as a 

 narrow stripe. 



Wings normal, with thick veins; the thinning out of the 

 4th vein occurs suddenly at about ^ of its length ; cross- 

 vein rather oblique. Halteres orange, with dark stalk. 



Legs all orange-brown like the pleura, but slightly in- 

 fuscate dorsally on all the femora (less so on the front pair), 

 on the tibite, and hind tarsi. 



Abdomen somewhat flattened, dark brown, with sharp 

 narrow whitish margins ; ventrally all pale. 



Size 4 mm.
