female ; iu the male the borders of the forehead converge very markedly 

 towards the vertex of the head, while in the female they are almost 

 parallel. There are three bristles situated above the bristles on thegenae; 

 stripe on the forehead is smoky black ; sides of the forehead, and ocellus 

 patch, are yellowish, the latter being a little the darker; eyes very 

 thickly covered with prominent hairs; antennae blackish brown at the 

 base, appressed, the first joint short, the second somewhat produced, the 

 third more than twice as long as the second with a sharp angle on the 

 underside of the anterior portion, the hinder angle being rounded off; 

 the antennal bristle two-jointed, naked ; proboscis somewhat prominent, 

 palpi almost cyclindrical, but somewhat narrowed in front, the color 

 yellowish brown with a darker base. 



Dorsal thoracic shield yellowish grey, with four, almost equally 

 broad, blackish longitudinal streaks, which nearly reach the scutellum 

 behind, also a fifth similar streak, which becomes distinct on the trans- 

 verse suture and runs quite up to the scutellum ; the inner paired streaks 

 are somewhat narrower than the outer ; the sternal aspect of the thorax 

 is grey with white sheen ; the dorsal aspect and sides are thickly covered 

 with hairs. 



The scutellum is brownish with black base and yellowish grey sheen ; 

 on its outer edge are four long bristles. 



The abdomen, which consists of four segments, is produced — oval in 

 outline; the first segment is black; each of the following segments has 

 a central black stripe forming a continuous line, and in front a broad 

 yellowish white glistening connecting membrane; genitalia, in the male, 

 are black with reddish brown bristles at the extremity ; the ventral 

 aspect of the abdomen is blackish grey with narrow black connecting 

 membranes ; the sides of the second and third segments of the abdomen 

 are of a reddish brown ground colour. There are two stout bristles on 

 each of the first and second segments of the abdomen ; three pairs of 

 long stout bristles on the edge of the third segment, one pair being 

 situated on the upper surface and one pair on each side ; the posterior 

 segment is thickly covered with hair and bristles. 



Wings vitreous, proportionately of large size, without any marginal 

 projection, the first posterior marginal cell, directed towards the apex of 

 the wing, is open ; the fourth cell bends towards the third either along 

 its whole length or at one corner only, without further appendage of 

 veins, but with a wing fold that resembles a vein ; the apical transverse 

 vein is somewhat bent in towards the posterior marginal cell ; the poste- 

 rior transverse vein is slightly-s-shaped near the bend in the fourth longi- 

 tudinal vein ; the second longitudinal vein has several bristles at the 

 base ; the fifth longitudinal vein is distinctly wavy where it approaches 

 the margin of the wing ; the sixth vein is much bent and does not reach
