The larvoi still feed socially on the under side of the leaves, in 

 confinement hiding between the leaves in the breeding box. 



The head is black, as wide as the body. 'J'he jirothoracii: 

 shield is pitch-black, anil now is i/n'idcd />y a pale median line. The 

 boilv is bright yellowish-green. There are lliiee liorsal iiark hroii'n 

 lines^ the median less broken than the others. 'I'he tliree 

 lateral lines are now ilis/i/ief, the niiildle one being one-half as wiile 

 as the others, the two others bearing the larger subtlorsal and 

 lateral tuberiles respectively. Tiu' situation and relative jiropitr- 

 tion in size of the tubercles (which are dark) are as described in 

 Stage I ; the two large twin dorsal pairs on abdominal segments i 

 and 8 are lari^er, higher and more ilistinet than before, ami eaeli hears 

 about four or five stif, dark bristles of unei/i/al size and leni:;th. The 

 suranal plate is blackish. The hairs are now slender, pale or dull 

 whitish, tapering, and in general about as long as the body is 

 thick. The legs as before, but the abtloiniiial ones with a larger 

 and rather more distinct scjuarish chitinous jiatch above the planta. 

 (Described soon after moulting). 



vSr.AC.K III. — (Described .Aug. 29, immediately after moulting). 

 Length, 12 mm. The head is now not so wide as the body, black. 

 The prothoracic shield is distinctly divided. Eody bright, glis- 

 tening, yellowish-green, with three narrow dorsal black lines, the 

 median one less broken than the others. These are succeeded by 

 a broad diffuse subdorsal, almost ilouble black stripe, on which a 

 black piliferous wart is situated, one for each segment. Helow is 

 a similar wart — including broad line, and above and below this is a 

 fine black-brown, somewhat broken line ; the lower one is the 

 spiracular line, the dark spiracles being minute and interrupting 

 the line, so that there are four instead of three lateral lines in this 

 stage; the additional line being the lowest or s|)iracular one. 



The two large twin tubercles on the ist and 8th abdominal 

 segments arise from a common tleshy humi), that on the 8th seg- 

 ment being slightly the smaller of the two jiairs. l"',ach bear 6-7 

 black hairs. The hairs are in general sordid white, and are not so 

 long as the body is thick. " The suranal ]:)late is large, black, and 

 the anal legs are nearly all black on the sides. 



Reeapitulation. (Corrected from that published in Proc. Host. 

 Soc, XXIV. 517). 



In stage I the two median dorsal tubercles on the 1st and 8th 

 abdominal segments are larger than the homologous ones on the 

 2d to 7th abdominal segments, and each pair is situated on a 

 brown raised iiround.
