 low hyaline; three discoidal areas; two transverse rows of light 

 brown spots in central portion, three spots in first row and six in 

 second. Under surface of body black. Legs dark brown, tarsi 

 yellow; first and second pairs of tibiae much flattened.

 of spots. 



2. Tropidoscyta binotata, sp. now (Fig. 2). 



Close to the preceding, but larger and differs in sculpture and 

 colour. May be easily recognized by the single ridge over each 

 humeral angle, and by two white spots on the median dorsal line. 



Head, body, wings and legs uniform yellow, except eyes, which 

 are dark brown, and two white spots on median ridge of pronotum, 

 one just before the middle and one just before the extremity of 

 posterior process; each white spot having a black mark at each end. 

 Head about twice as long as wide, lorae extending slightly beyond 

 internal margin of eyes; finely punctate and pubescent; ocelli 

 farther from each other than from the eyes. Pronotum strongly 

 projecting forward, finely and deeply punctate and sparsely pubes- 

 cent with golden hairs; median ridge strong and percurrent, very 

 lightly sinuate; posterior process gradually acuminate, somewhat 

 depressed at apex and extending beyond internal angle of tegmina 

 and beyond abdomen; one strong lateral carina on each side, start- 

 ing at extreme anterior apex of pronotum and extending to a 

 point on the lateral margin, one-third way from humeral angle to 

 posterior end. Tegmina opaque yellow, without markings, base 

 and costal areas densely punctate; three discoidal areas. Legs 

 yellow; fore and middle tibiae much flattened; hind tibiae thin, 

 with black-tipped spines. Tarsi concolorous yellow.
