The legs are similar, but the anterior pairs much shorter. 

 The measurements of the different parts of the hind leg are: 

 Coxa, 51 /x; trochanter plus femur, 78 /*; tibia, 69 ^; tarsus, 60 /*; 

 claw, 21 fx. 



The margin of the body bears a continuous row of rather 

 short spines, truncate at the apex, and measuring a maximum 

 of 18 ix in length. Thoracic incisions (Plate 1, fig. 2, b) normally 

 with four spines, which are slightly longer than the marginal 

 ones, the apex of these spines being blunt as in the adult. 

 About ten small circular pores occur between the spiracles and 

 the body margin. The anal plates are similar to those of the 

 adult female in general shape, with a distinct apical spine. 

 The anal ring bears eight hairs. 



The first-stage larva, male. — Similar to that of the female, but 

 somewhat broader (Plate 2, fig. 3). Legs and antennae stouter, 

 the latter 6-jointed (Plate 1, fig. 3, a). Marginal spines (Plate 

 1, fig. 3,6) as in the female, but those of the thoracic incisions 

 fine hairs (Plate 1, fig. 3, c) instead of blunt spines. 



The second-stage larva, male. — General shape broadly oval 

 (Plate 2, figs. 5, 6, 7, 8), widening in the abdominal region. 

 Antennae and legs small and weak. Antennae 7- instead of 

 6-jointed 5 (Plate 1, fig. 4, a) as in the female. 



The measurements of the different joints are as follows : 



The body margin with fine hairs, much fewer than in the 

 preceding stage. The thoracic incisions with two sharp spiny 

 hairs (Plate 1, fig. 4, 6), and the dorsal surface with numerous 

 small pores. Other characters are similar to those of the female. 



Immediately before 6 the second molt the body becomes plump, 



•Sasaki (17) states that the antenna? at this stage consist of three joints 



* The third stage of Sasaki < 17 > is really the second-stage larva just before 

 the molt. Fig. 10 of Yano<20) appears to me to be also the second-stage 

 larva just before the molt, rather than the third.
