LAMPIDES BOETICUS. 355 



attached the dorsal headpiece, that of either side is about 08mm. long 

 (from side to side), about 0-17mm. wide (front to back) in the middle 

 narrowing to a point externally, and to a very minute (O03mm.) 

 margin, to articulate with its fellow, and most of this is beneath the 

 margin of the prothorax ; it is reticulated as the rest of the pupa, but 

 appears to have no hairs or lenticles. The mesothorax has a length 

 of about 3mm. down the dorsal suture, but is less than 2mm. long 

 measured down to the sinus, into which the metathorax intrudes ; its 

 sinuous front margin, of about 2mm., has a large (034mm. long) 

 elevation, beginning 0-25mm. from where it meets the antenna ; this 

 is the cover of the first spiracle, itself a very simple structure in a 

 hollow beneath it ; this operculum possesses an enormous number of 

 fine processes, each of which is a little pillar, spreading out into a flat 

 or rather cup-shaped top ; the dorsum of the mesothorax possesses a 

 very few scattered hairs and lenticles ; there is a little fulness at the ' 

 base of the wing, but nothing to be called a wing-spine ; the wings 

 have no hairs or lenticles ; the netting over the dorsum has the 

 transverse lines strong, like a number of parallel streams with short 

 side affluents, since these longitudinal branches seldom meet each 

 other ;" on the wings the arrangement is more irregular, but has the 

 same dendritic character of principal ridges with branches not linked 

 up, rather than a network. One sees here, as elsewhere, that, on the 

 dark spots, the lines of reticulation are nearly black ; in the less dark 

 patches elsewhere, they are merely of a slightly darker tint than the 

 general surface. The metathorax has the usual form of a narrow 

 dorsal isthmus (about 025mm. long), widening to about 1-2 mm. 

 where it extends up into the mesothoracic sinus, and narrowing to a 

 fine point at the 2nd abdominal segment ; the narrow slip beside 

 the 1st abdominal segment is really the hindwing, but there is nothing 

 to mark it off from the rest of the segment ; there are, on either side, 

 perhaps, a dozen hairs, and as many lenticles, quite scattered ; about 

 the centre, on each side, is a comparatively large hair, of exceptional 

 and delicate structure (0-2mm. or 0'25mm. long), so as to be somewhat 

 injured (apparently) in my preparations. The 1st abdominal segment 

 is about 2-3mm. long, and 045mm. wide, dorsally ; the fine lines of 

 netting are chiefly longitudinal, and it has more numerous skin-points 

 (or intersections of lines of netting) than the thorax, and a few hairs 

 and lenticles ; it has a dark mark at the anterior and posterior angles 

 of the outer margins. The 2nd abdominal segment has, of course, a 

 pair of spiracles ; it is 0*8mm. long in dorsal line, and about 2-6m.ni. 

 wide ; the spiracles have a crowd of lenticles, chiefly behind them, 

 nearly 40 in number, with a number of hairs ; the general surface has 

 scattered hairs, lenticles, and skin-points. A similar description with 

 obvious modification would apply to the 3rd, 4th, 5th, and 6th abdo- 

 minal segments. The 7th abdominal segment has many fewer hairs 

 and lenticles in attendance on the spiracles, and the 8th has no 

 spiracle, but only the scar, where it is obsolete ; on the 7th abdominal 

 segment, the scar of the honey-gland is a marked feature ; near the 

 posterior border of the segment is a transverse line, about - 15rnm. 

 long, of dark thick chitin with a small excrescence on either side ; it 

 is surrounded by an area 04mm. from back to front, and 08mm. 

 wide, free from skin-points, reticulations, hairs, and lenticles, but with 

 radiating lines as if there were some central contraction. On the 8th 

 abdominal segment, a little outside the scar of the spiracle, and near
