PROCEEDINGS OF THE THIRD ENTOMOLOGICAL MEETING 837 



row of tubercles and spots and- their relative position on the sides of the 

 larva is nearly the- same all through the first stage, except that the spots 

 on the second and third segments are longer and obhquely set and on 

 all other segments are behind the spiracle, as it is set on the extreme 

 anterior edge of spot. The seiond and third segments have a blood 

 crimson oval mark on each end of which is set a pale trausj^arent yellow 

 tubercle with slender yellowish spines curving mostly dorsally and 

 backward, and is very noticeable. Forward and also behind in a dorsal 

 ■hue is a long black spot broken at the intersections ; both at the fore and 

 hinder lateral edges, other spots (the submedian row of black spots). 

 Lateral ruga (the infraspiracular line of Packard) is more yellowish and 

 not very pronounced. Abdominal legs greenish yellow. Suranal plate 

 same colour with a broad heartshaped black centre and edged anteriorly 

 with black. Anal legs with small black spot. There is a slight varia- 

 tion in the amount of spots and markings of these larvae. 



Larvae spun up 21st April. Moulted 24th April. 



Length end of first age 7 mm. 



Second Age. The first larvae moulted 24th April, aged eleven days. 

 Head and feet glossy black. Dorsal surface milk-white, lateral surface 

 pale-gold. The black spots along the sides are broken up and the cara- 

 pace is now only edged behind with a narrow line of black which extends 

 in a median line to the anterior edge. Dorsal tubercles of second and 

 third segments are larger and of the crimson colour of the oval raised 

 spots they spring from and with short carneous spines and a very short 

 white hair in the centre. The rest of the dorsal and all the subdorsal 

 tubercles have a very long white hair in the centre of each, which is 

 wanting on the subspiracular row. Suranal plate triangular and nar- 

 rowly edged black. Anal legs with curved black mark. In this stage 

 the whole larva is covered with fine milk-blue hairs from body, longer 

 from the tubercles, except those from carapace ; last two Segments and 

 subspiracular tubercles pale maize yellow. 



Comparing it with D. japonica and D. simla of same age ; whilst 

 C. cachara resembles D. simla in fourth age, but with the addition of 

 four red tubercles, D. japonica is all black and the dorsal tubercle hairs 

 of second and thnd segments are the longest. These in cachara are the 

 shortest and spring from large red dorsal tubsrcles. Ths, dorsal line of 

 tubercles in japonica are relatively taller and armed with stronger spines 

 than cacliara where except for the two red pairs they are only papillate. 

 Length of larva at end of second age about 10 mm. 



Third, Age. Moulted 5th May, aged 23 days. Hardly differing from 

 last excepb that the black marks are more broken and scattered, ending 

 abruptly just above the yellow lateral ruga and re-appearing faintly
