may readily escape notice ; the body terminates in two short 

 and blunt processes directed backwards ; the legs and claspers 

 form two approximate series under the belly, and are not per- 

 ceptible from above, whether the larva is at rest or in motion. 

 The general colour of both the head and body is wainscot- 

 brown ; the ocelli are black, and one on each side is unusually 

 prominent, appearing almost pedunculate ; the body has a 

 narrow medio-dorsal stripe almost black, and the colour on 

 each side of this is paler than the general ground colour, thus 

 rendering the medio-dorsal stripe more conspicuous ; the 

 spiracles are intensely black ; half-way between the spiracles 

 and the medio-dorsal stripe is a side stripe, paler than the 

 general ground colour, but bordered, especially below, by a 

 darker margin which is broken up into elongate spots, but 

 these are rather vague, and not very noticeable ; the legs, 

 claspers, and under surface are nearly of the same tint as 

 the dorsal surface; the warts are of a very pale hue, 

 almost white, each having in the centre a small black hair. 

 It was full fed at midsummer. I am indebted to Mrs. 

 Hutchinson, of Grantsfield, near Leominster, for the oppor- 

 tunity of describing this previously unknown larva. — Edward

Description of the Larva of Thecla BetulcB. — Rests in a 

 flat position on the surface of a leaf, with its head, legs and 

 claspers concealed, and it does not abandon this position 

 readily : when compelled to do so, it falls about three inches 

 and hangs by a thread. The head is almost globular, but 

 slightly produced towards the mouth : it is scarcely half so 

 wide as the 2nd segment ; indeed the head may be said to 

 be retractile within that segment : the body is shaped some- 

 what like a little boat turned keel upwards : the sides are 

 dilated all round, even including the 2nd segment, the 

 anterior margin of which projects beyond the head : the 

 segments are deeply and distinctly divided, so much so as to 

 give the back, when viewed sideways, a serrated appearance ; 

 the dilated sides and dorsal keel are each garnished with a 

 fringe of stiff hairs ; this fringe is double on the dorsal keel, 

 but single on the lateral dilatation ; on the former each hair 

 is curved into the segment of a circle, and its end is directed 

 backwards ; on the margin each hair is also curved, but 

 more slightly, and its end is directed downwards. The colour
