AGRIADES THETIS. 



thick, bulging, and giving the pupal projection here already noted ; 

 they shut out the second leg from the head (as in all Lycaenids) but are 

 short. The whole pupa (except appendages) has a sparse coating of 

 very short dark hairs, only visible with a lens, a little more numerous 

 and larger down the dorsum and round the spiracles. The pupa is 

 everywhere fairly rounded (in transverse section); the ventral line is 

 fairly straight ; starting from the labrum there is a slight prominence 

 of the first legs about middle, 2mm. from front ; then, again, at about 

 the 1st abdominal segment, it bends out (i.e., ventrad), at about 3* 5mm. 

 from the front, and continues in the new direction to the end of the 

 wings (8mm.), although rather short of it in one specimen, when it 

 again curves inwards (dorsad) and continues to end (2mm. further). 

 This is in a specimen 10mm. long. A line drawn from the labrum to the 

 9th abdominal segment would show a prominence about 5mm. long, 

 and with about 04mm. of greatest projection, just before the end of 

 the wings. The remaining outline (chiefly dorsal) on side view, 

 consists of the rounded head, very similar dorsally and ventrally, 

 lmm. long, and 2mm. of vertical diameter, where it meets prothorax 

 there is a slight re-entering angle ; the dorsal line rises again to 

 about 3-Ornm. from front, to a height of 3-8mm. ; it falls again down 

 the back of mesothorax to a marked but not deep waist 4mm. from 

 front, thickness 3'5mm. in the middle of the 1st abdominal segment ; 

 thence it continues nearly parallel at first with the ventral line, but, 

 gradually increases its curvature to the end of the pupa, meeting the 

 ventral line at a right angle, the junction, however, being rounded, 

 somewhere on the dorsum of the 10th abdominal segment. Before 

 thickening from the developing imago occurs, the glazed eye is brown 

 and is marked off from the face by a nearly black fine line ; the first 

 spiracle is a conspicuously brown short fine line, against the pro- 

 thorax, which, itself, is conspicuous against the wing-bases by its 

 browner colour and dark hairs ; it is in one specimen, not in others, 

 markedly browner than the mesothorax. The abdominal incisions are 

 marked by the segmental margins being raised in slight ribs. The 

 front of the pupa is of ordinary Lycaenid pattern. The jaws meet for 

 a short distance, so that the apex of the (slightly darker) labrum is 

 some way from the bases of the maxillae. In one specimen, a trace of 

 labium appears between (not the maxillae but) the lower angles of 

 the mandibles. A fairly straight transverse line, 1-5 mm. from front, 

 divides the face from bases of maxillae and the first legs. The 

 maxillae, except a very slight and short widening quite at the tip, are 

 of uniform width till they disappear (5mm. from front) beneath the 

 antennae. The second legs reach (in a point) the angle formed by the 

 antennae crossing the maxillae, and the first legs also end in a sharp 

 point 3mm. from front (at the incurving of the ventral line); basally 

 they are very large and abut against the antennae for about 0*6mm. 

 The pupa is comparatively well-supplied with hairs, but they are very 

 short, about 0*1 mm. in length, some fractionally larger, some shorter. 

 On the prothorax on either side are about 21 hairs, massed towards 

 the outer angle and front of inner margin ; one or two of these are a 

 little shorter and clubbed ; lenticles are exceedingly numerous, being- 

 packed closely together over much of the outer half of the plate ; some 

 of these are of large lumen up to 0*025mm., others small ; the smaller 

 they are the more chitinised are their rings, so that it is difficult to
