segments III and VII 1 : 1-2-1-8 (1-4) and 1-1-2 (i-i) : 1, respectively. Segments V and VI 

 becoming progressively wider, and segments VII and VIII decreasing in width. 



The lengths, widths of the flagellar segments and the number of setae on each are given in 

 the following table :

Antennal bristles well defined ; segments VI and VII each with one ventral bristle. Terminal 

 segment with 3 preapical bristles, a pair of capitate sabapical sensory setae and one apical 

 hair-like seta. 



Thorax : The thoracic ridges and sclerites greatly degenerate. ' Pleural ridges of thorax 

 short and rudimentary. Spiracles 9-12 (10) u. wide at opening, with 24-31 (27)^ long supporting 

 bars. Prothoracic and mesothoracic setae : 2-3 (25) dorsal, one pleural, and one ventral setae 

 present on each side of the median line. Metathoracic setae : 2-3 (2-7) dorsal, and one pleural 

 setae occur on each side. 



Legs : Comparatively short and very stout , the fore and the middle legs subequal in length, 

 the hind leg slightly longer ; the ratio length of the hind leg to the total length of body 

 1 : 2-9-3-4 (3 -2 )- Coxa and trochanter about 31 and i8[i wide respectively ; the latter with 

 a differentiated long apical seta. Femur about 28^ wide ; that of the middle leg shortest and 

 those of the fore and hind legs subequal ; the ratio width to length of the hind femur being 

 1 : 1-8-2-0 (1-9). Tibia about i8(x wide ; with 2 small spines ; in fore leg the ratio lengths of 

 femur to tibia 1-4-1-5 (1-45) : 1. Tarsus about i8(x wide ; tarsal digitules apically knobbed, 

 about 24 u. long. Claw broad at base and abruptly tapering apically ; ungual digitules also 

 apically knobbed. The lengths of the leg segments (in microns) and the number of setae on 

 each are given in the following table :

Abdomen : Abdominal tergites and sternites absent. Abdominal setae on each side : 

 Dorsal setae usually 2 and sometimes only 1 on segments I to VIII. Pleural setae always 1. 

 Ventral setae 1 on segment II, 2 on segments III to VI, and 1-2 on segments VII and VIII. 



Ostioles as well as glandular pouches entirely absent. Genital segment : Genital capsule
