8 THE entomologist's RECORD. 



September 12th, and the moths emerged about October 20th. A 

 short description of the larva is given. I will now proceed to give 

 descriptions of the larva at two stages of its life : — 



1. Taken on Deconber 12th n-hen about half-i/rown. — Head dark 

 brown and shining, smaller than second segment ; whole of the upper- 

 surface olive-green, thickly irrorated Avith paler dots ; spiracular stripe 

 pale yellow ; spiracles yellow and seated in a pinkish blotch ; central 

 surface paler ; legs brownish-green. 



2. Description of fallfiroini larvae taken Jannanj 4th. — Length a little 

 over an inch, plump and cylindrical ; head rather shining and smaller 

 than the second segment, dark olive-brown, reticulated with darker 

 spots, with a pale v-shaped mark above, and a small whitish blotch on 

 each side of the mouth ; the larvse vary in colour on the upper surface 

 from olive-green, some being almost black, and in others the olive- 

 green is tinted with red ; the whole of the upper surface delicately 

 reticulated with minute golden-brown atoms, more conspicuous in 

 some than in others ; a very narrow pale dorsal line, almost obsolete 

 in some cases ; on each side of the dorsal line on each segment, a 

 minute white dot ; spiracular stripe distinct, pale yellow above tinged 

 with pink along its lower edge ; spiracles pale yellow with a pinkish 

 blotch below them ; in some varieties there is a rather broad darker 

 stripe above, including the spiracles ; under surface greenish-pink, 

 irrorated with paler dots ; legs greenish-brown ; claspers paler. The 

 larva has a very soft velvety appearance. 



I am indebted to the kindness of Mr. A. Bacot for the following 

 notes and descriptions of the young larva and pupa : — 



Larva. — First instar: When first hatched they were inclined to 

 feed in small batches of four or five, but some six or seven 

 days later they were all feeding separately, eating out the cuticle 

 (either upper or under, indifterently) of the dock-leaf. Shape : 

 Cylindrical, short and stout, with plump or swollen segments, 

 anus rounded. Head : Small and rounded, very highly polished 

 surface, black with black hairs. Juxli/ : The meso- and metathorax 

 and first four abdominal segments show a subsegmental division 

 dividing the segment into two subsegments, but the remaining 

 segments are full and plump, showing no signs of subdivision. 

 The skin is smooth and shining, of a very pale green, with a coat of 

 minute spicules. The prothoracic plate or scutellum is large and all 

 but black, and one would call it highly polished were it not for the 

 fact that it is put somewhat in the shade by contrast with the 

 excessively polished head. A small and similarly coloured anal plate 

 is present. True legs dark. There is little or no difterence in the 

 development of the prolegs, perhaps the first pair are very slightly 

 smaller than the following ones, but there is practically no loop in 

 crawling, only an undulation. The hairs (setfe) are rather short and 

 stifi', dark-coloured, and slightly clubbed or thickened at the tip, the 

 tubercles — at their bases- — are dark brown and chitinous in character. 

 The dorsal tubercles on meso- and metathorax are i small inner, ii large 

 outer, in transverse line, and on abdominal segments they are of about 

 equal size ( = ii of thoracic), and set as at the corners of a trapezoid. Of 

 the lateral tubercles on meso- and metathorax, iii is in transverse line 

 below ii, iv below lii, v anterior and below iv ; the subprimary below,
