122 BRITISH BUTTERFLIES. 



double yellow line (outside dorsal band) is yellower in front, ~and"is 

 continued down head on either side as a yellow longitudinal frontal 

 line. Head otherwise green, with six eye spots. The ijaws *whitish 

 with very dark brown margin and teeth, the cheek behind them'forming a 

 yellow and brown marginal area. The surface of the head has a 

 slender clothing of very minute hairs, and is very finely pitted, the 

 margins of the pits run to some extent into lines, looking like a series 

 of waves. The skin-points are very indistinct over most of the surface; 

 on the thorax, however, they present minute black rings, some with 

 very short white hairs, and on the 9th and 10th abdominal segments 

 they again look like hair-points, and graduate into the actual hairs 

 forming the fringe round that end of the larva. There is one hair on 

 the prothorax, at anterior lower angle of plate (if there is one, the 

 texture looks like the rest of the larva). The underside is apple-green in 

 tint, and underneath the 7th and 8th abdominals is already indicated a 

 pale shade, though larva is not yet fullfed. These patches are one on 

 each side, beginning at front of segment and ending in a rounded 

 margin before middle of segment, they are crossed by a slight (inter- 

 segmental ?) fold. These ultimately shed the white powder at pupation. 

 The larva has little of the marked neck which characterises the 

 Hesperiid section, indeed, it is not noticeable. The thoracic plate in a 

 prepared specimen is seen to be a very narrow transverse strip, with 

 several abortive hairs. It has a transverse ridge, and, in front of this, 

 some raised network markings. The prothoracic segment is definitely 

 narrower than the mesothorax — it has parallel sides, is just wider than 

 head (2-lmm.), but (at rest) is very narrow from back to front 

 (about 03mm.). The mesothorax bulges out to 2*8mm. or 3-2mm., 

 and has a rounded margin. The larva is about 3'5mm. wide to 

 7th abdominal segment — fairly cylindrical, the true legs short 

 and stumpy, hardly tinted ochreous, the prolegs very short on 

 low eminences, so that the larva is almost as round below as above. 

 The prolegs have crochets on about five-sixths of their circle, the 

 unequipped portion being the outer and slightly posterior. They are 

 single and about seventeen in number in front ; behind are alternate 

 large and small hooks (in one row), and about sixteen or seventeen of 

 each. The outer and inner bosses (basal eminence and shaft or pillar) 

 form one rounded base, divided by a line, each has rather numerous 

 very fine hairs, and there are a few above and in front of the base. 

 Lenticles are not very definite, but circles (or ovals) entitled to be so 

 called occur (1) at bases of the legs, (2) on dorsum (tubercle i?) of meso- 

 thorax, and (3) on abdomen above situation of vand of vi, i.e., two at about 

 equal distances below spiracles. The anal plate is colourless (green), 

 and reticulated with similar sculpture to that of head and prothoracic 

 plates. There is a supra-anal comb about 04imn. long and 03mm. 

 wide with about twenty teeth (Chapman, June, 1905). himd instar 

 (June 23rd, 1873) : 19mm. -22mm. in length, in figure (omitting the 

 head) tapered a little to each end, the prothorax being the smallest and 

 very short. The head swells out beyond the size of the prothorax, but 

 not to such an extent as in some other allied larva 1 (Buckler). Of a 

 pale greyish-green, the dorsal vessel darker, edged with a slender pale 

 yellow line on each side, and enclosing a pale longitudinal line along 

 its middle. A narrow yellowish line runs above on the side, and a 

 broader one below. The two dorsal lines are prolonged as far as the
