EVERES ARGIADES. 87 



The 3rd abdominal segment is nearly 1mm. wide and 3*2mm. across, 

 the ends, of course, obliquely ; it has 16 or 18 hairs on either side, and 

 lenticles as in the 2nd abdominal segment. The 4th abdominal seg- 

 ment is about 0-7mm. wide dorsally, and extends (narrow ventrally) 

 round the pupa. The 5th abdominal is about 0'7mm. dorsally, and 

 is only about 02mm. ventrally, but of weak and collapsible tissue. 

 The 6th abdominal is 07mm. dorsally, and 0-2mm. ventrally. The 

 7th, about the same dorsally, but almost evanescent ventrally ; it has 

 only nine or ten hairs on either side, but, like all the preceding seg- 

 ments, has the swarm of lenticles near the spiracle. The 8th 

 abdominal segment is about 0.5mm. wide dorsally, hardly distinguish- 

 able ventrally ; its obsolete spiracle has sixteen or eighteen lenticles as 

 satellites, and there are eight or nine hairs on either side. The 

 9th abdominal has dorsally fourteen hairs, but for the rest is in- 

 distinguishable from the 10th abdominal'segment by any definite sutures. 

 All these segments, 3rd to 9th, are very similar in the spots and sculp- 

 turing. The somewhat circular area, consisting of the 9th and 10th 

 abdominal segments, has, like other Lycsenid pupaa, a transverse curved 

 suture, nearer its ventral than dorsal margin, and a short one at each 

 end of this, parallel, and close to the suture of the 8th and 9fch abdom- 

 inal segments, and a good way ventral of the obsolete spiracle. The 

 crem astral hooks are arranged in a circular area, wanting, however, at 

 the anterior (or ventral) margin ; on the dorsal margin of the circle 

 they divide the ordinary sculptured and hair-carrying surface of the 

 9th segment from the central area of the circle which has a trans- 

 parent, colourless, membranous structure, studded, however, 

 centrally, with minute skin-points, sharp, and directed forwards, a 

 " forwards " that would be backwards, but for the great incurving of 

 the dorsal surface. What is anterior anatomically is, here, posterior 

 topographically. It is just possible to recognise that the hooks have 

 an upper (posterior or dorsal) set, dorsal to the transverse suture, 

 consisting of about 120 hooks, and two lateral patches below this 

 suture, each of about 30 odd hooks. The hooks have short, thick, 

 stems, somewhat curved, with anchor-ends set on a little sideways ; 

 their length is about 0'045mm., with a few longer up to twice this 

 length. The spiracles are about 0-lmm. long, and 0-07mm. broad, 

 rather larger on the posterior segment ; the opening is a narrow slit, 

 surrounded by a radiating grid, each ray of which is double, as if folded 

 at the outer end. The sculpturing is apparently the same over the 

 whole surface, but can often hardly be seen, except in the dark spots ; 

 it is a raised, interlacing set of ribs, sponge-like in their anastomosis, 

 and with the appearance of passing behind each other ; here and there 

 their branches dwindle down into very fine skin-reticulation. The 

 rosettes (about O'Olmm. across) of the reticulation are very flower-like 

 (like a single rose), with a central spot and radiating lines dividing the 

 outer portion into four or five petal-like pieces. These rosettes occur very 

 distinctly in places where the network is almost invisible, always at 

 crossing-places of the network, and, as usual, hairs and lenticles are 

 never on the lines of network. The lenticles near the spiracles are 

 0'04mm. across, sometimes, perhaps, 0*05mm., and vary down to a 

 third, or even a fourth of that diameter; their membrane is always 

 beautifully dotted. The hairs have colourless and structureless walls, 

 about a sixth of their diameter in thickness, and appear to be marked
