ish amber or (in tlie finer parts) to very light or whitish amber ; but 

 where visible without a lense, the cross veinlets when magnified appear 

 pitch black or pitch brown in opaque view, and this colour remains 

 fairly constant from most stand-points ; the subcosta and radius and 

 also in some positions the great cross vein are likewise piceous. Hind 

 wing spotless, and clear throughout. Fore leg raw umber brown, 

 blackened at the tip of the femur and at the base and tip of the tibia. 

 Hinder legs light yellowish amber colour. 



Abdomen pale ochraceous or whitish raw umber grey in the first 5 

 segments, and light brownish ochre in the hinder segments, marked with 

 black lines and streaks disposed mainly in two longitudinal series : seg- 

 ment 1, spotless; segment 2, with a faint dot near the base on each side 

 of the dorsal vessel, and a larger spot below the dot just above the main 

 trachea, which spot is not represented in the other segments ; in seg- 

 ments 3 to 9 the markings corresponding with the said dots take the forms 

 of an oval spot in the 3rd segment, an abbreviated tapering streak in 

 the 4th, a tapering streak produced to the hind margin in the 5th seg- 

 ment, and apparently continuous lines from the 6th to the 9th segment. 

 Venter marked longitudinally, in segments 3 to 5 with two abbreviated 

 tapering streaks ; in segments 6 to 8 with two thin tapering lines ; and 

 in segment 9 with two linear stripes. Setse ochraceous, with opaque 

 joinings. 



Dorsum of $ in segments 3 to 6 longitudinally bilineate, with an 

 additional black line on each side in segments 7 to 9 pai-allel with and 

 exterior to the principal lines in the hinder f of each segment : on the 

 pleura of most of the segments is a short marginal streak at the base, 

 and a longer streak just inside the margin near the tip ; on each side of 

 the 2nd segment is an erect spot like a mark of exclamation. Hind 

 wing spotless ; neuration indistinct to the naked eye. 



Length of body 12; wing S 12, 2 15-21; set^ 2 subim. about 

 17 m m. The specimens are infested with encysted parasites.
