72 STENIA PUN0TAL1S. 



pitted all over the slightly convex upper surface ; in 

 colour it is yellowish; its long diameter is about 



iJL 

 14 



mm., the shorter diameter -f± mm. 



The newly hatched larva is yellowish in colour, 

 with dark head and collar, slender, with the segments 

 well defined ; it at once spins a silken covering, under 

 which it feeds ; it grows away through August and 

 September. I have just now (8th of October) mea- 

 sured one, which is quite 12 mm. long, slender in 

 figure, viewed from above pretty well uniform in 

 bulk, except that the first segments taper slightly, 

 but sideways the front segments and head are seen to 

 taper considerably ; the skin is very glistening and 

 translucent, the colour a pale but warm amber, the 

 food showing through blackish in whatever region of 

 the internal vessels it happens bo be ; the head is very 

 shining, of light red tint; the collar on the second 

 segment is large, brown, its pale median line edged 

 with almost blackish-brown ; the usual dots are small, 

 black, placed on large glittering warts darker than 

 the skin, those on the third and fourth darker than 

 the rest ; spiracles indistinct ; legs pale ; like the larvse 

 of Pyr alidad generally, it lives quietly enough on or 

 among its food, but is very active when disturbed, 

 wriggling and jumpiug backwards or forwards with 

 agility. 



The full-fed larva is about 19 mm. in length, with 

 proportions much as before, slender, being stoutest at 

 the eighth segment, with the back tapering each way 

 slightly in a curve, the head narrower than the second 

 segment; the skin at last less translucent, but still 

 very glittering ; general colour of a pale yellowish 

 stone tint, but all the middle space of the back shows 

 ashy grey from the internal vessels, and through this 

 space runs the darker interrupted pulsating dorsal 

 vessel; the segmental folds also show darker; the 

 head is very glittering, in colour clear reddish-chest- 

 nut ; the collar is of a much darker brown, reaching 

 across the whole length of the second segment on the
