346 BRITISH BUTTERFLIES. 



leg are seen, in one specimen, to be accompanied by a battledore palpus 

 on leg or the claw." The general surface is closely-set with minute skin- 

 points which are smooth and rounded and nearly colourless, only on the 

 front margin, laterally and below, on the prothorax, are they anywhere 

 found to be sharp and spicular. The hairs are very straight, un- 

 spiculated, and have smooth conical bases. The special points, in 

 which this larva differs from those of more typical Lycsenids, are — in 

 the straightness and smoothness of the hairs, in tubercle ii being- 

 absent, in iii carrying a strong well-developed hair without' an accessory 

 one, and in iv and vbeing apparently present as such, and not represented 

 by three hairs. The dorsal gland of the 7th abdominal is not to be 

 detected in this instar. Second instar: About l-6mm. long, 04mm. wide, 

 with sides nearly parallel to the 7th abdominal segment ; green with 

 reddish lateral and dorsal flanges, and some tinting between (really 

 the larva varies much in colour and is rarely as much coloured with 

 reddish as is this specimen). No trace of the special glands of the 

 7th and 8th abdominal segments could be seen in first instar ; those 

 on the 8th cannot now be made out, but there is a distinct transverse 

 line on the 7th, marking the honey-gland of that segment. The 

 head is black, 0-4mm. wide, with a neck of at least its own length. 

 On the prothorax there are about 25 hairs on either side above spira- 

 cular level (8 or 9 in first stage) ; the prothoracic plate cannot be 

 clearly defined as it is of the same colour and texture as the rest of the 

 segment ; the longest hair is about 0*1 5mm., perhaps a dozen are very 

 little shorter, the rest decrease to 0'02mm. or less. There are 5 or 6 

 lenticles (above spiracle) nearly symmetrically placed, and the spiracle 

 is large, raised, with a sloping rim, about one-third of the width of the 

 opening in height. The distribution of hairs seems very much alike 

 on all the following segments to the 6th abdominal ; there are, on 

 each side, above the spiracle, about 12 or 13 hairs, not very clearly 

 divided into a dorsal and a subdorsal group, nor is the dorsal distinctly 

 divided from its fellow of the opposite side ; on one or two segments 

 there appears to be a mediodorsal hair ; these hairs vary from about 

 0'8mm. to 0*14mm., one or two on some segments being perhaps even 

 longer ; there is a hair (about Olmm.) in front of, and one behind, the 

 spiracle ; the subspiracular, or flange, group contains six or sometimes 

 seven hairs, usually with one about, or nearly, 0-2mm. long, the rest 

 shorter. This group is more distinct and definable from the others 

 than any of those above spiracle ; below this is a group of three or 

 four hairs, one long (016mm.) and one or two shorter ones ventrally ; 

 the hairs on the 7th, 8th, 9th, and 10th abdominal segments are dis- 

 turbed by the dorsal gland of the 7th and the anal plate, the latter a 

 rounded area, without hairs, about O07mm. across. The flange-hairs 

 round these segments cannot be definitely assigned to each, but small 

 hairs are very numerous behind the 10th. The spiracles are large 

 (0*01 5mm. in diameter) ; they have a dark margin and a central circle 

 (the real lumen ?) about two-fifths of the total width. The skin is covered 

 closely with rounded skin-points ; they have, however, sharp points 

 round the front of the prothorax. The lenticles are difficult to define ; 

 on the central abdominal segments is one a little above the spiracle, and 



* 1 have not been able to prepare a skin, flat, and though I am fairly confident 

 that the above description is accurate as far as it goes, the difficulty of making out 

 minute detail may have resulted in some omissions, especially perhaps of lenticles.
