to meet in the mid-line, are the tibiae of the third legs. The tibiae of 2 

 appear from beneath the caudal extremity of the first legs and reach about 

 half-way between the caudal extremities of the second and third coxae. 

 Third legs appear from beneath their corresponding tibiae. They meet 

 in the mid-line and extend as far caudad as the upper border of the last 

 segment. Antennae narrow, slightly tapering, segmented but not deeply ; 

 terminate in the female between the caudal extremities of the third coxae 

 and second legs ; in the male extend, together with the forewings, to the 

 caudal extremity of the last abdominal segment. Coxae of all three legs 

 broad, the first longer than the second and these longer than the third. 

 A small area of the ventral surface of the abdomen is disclosed between 

 the caudal extremities of the last coxae. Forewings in female terminate

in a pointed extremity just above the caudal extremity of the third legs; 

 in the male extend to the lower margin of the last abdominal segment. 

 Hindwings — occasionally a very narrow slip of these is to be seen between 

 the third legs and forewings, and extending very slightly caudad to these 

 latter. 



Dorsally : Front shallow ; prothorax very narrow ; mesothorax large ; 

 metathorax about half the length of the mesothorax. Hindwings extend 

 caudad as far as the second abdominal segment. Spiracles on prominent 

 elevations, segments 1 to 8 inclusive, the largest being on 2. Segments 3, 

 4, 5, 6, and 7 in the female bear a row of small spines somewhat irregularly 

 distributed so as almost to form two transverse lines at the upper extremity 

 of each segment ; the male has these on segment 8 also ; they are 

 interrupted in the mid-line by a slight medio-dorsal ridge. Under a fairly
