172 BRITISH BUTTERFLIES. 



hooks, and rather sharp tips (Chapman, June 4th, 1905). The pupa 

 is of the normal Lycaenid form ; the ventral area much flattened, the 

 line between head and anus along the medioventral area being almost 

 level. The dorsal area much, swollen and exaggerated. The body 

 consists of a very large globular abdomen and an equally swollen, but 

 actually smaller, thoracic region, viewed dorsally. The major portion 

 of the thorax is made up of the mesothorax, but the prothorax is also 

 large, and retains, to a considerable extent, its larval aspect as regards 

 its hood or shell-like shape. There is a marked constriction between 

 the thoracic and abdominal regions ; this is chiefly dorsal, but, to a 

 slight extent, lateral as well. The waist is deepest at the junction of 

 the metathorax with the 1st abdominal segment, but the silken girdle, 

 in the specimen under examination, lies in the incision between the 

 1st and 2nd abdominal segments, at a slightly higher elevation. The 

 measurements of the pupa are as follows: Length, 10- 50mm. ; width at 4th 

 abdominal segment, 5 -50mm. ; at mesothorax, 4-50mm. Thickness or 

 height is about the same at both mesothorax and 4th abdominal, nearly 

 5mm. ; at the waist, only about 4mm., or very slightly over. From the 

 head to the tips of the antenna- cases and wings is 8mm., and from the tips 

 of the wings to the anal end 2*5mm. The wings and antenna-cases extend 

 to the posterior edge of the 4th abdominal segment. All the segments are 

 fused, at any rate, prior to emergence. By lamplight, and with a 1" 

 objective, I cannot distinguish any special hooks or processes on the 

 anal armature ; there seems to be a number of the short, more or less 

 trumpet- shaped, bristles, but these are so numerous, and set at such 

 varying angles, that they would probably afford ample means of attach- 

 ment to the silk. The spiracles are but slightly raised, and form a slit- 

 like opening on a smooth, hairless, pale-coloured swelling. The dorsal 

 area, and well round the lateral area also, is thickly set with stout, 

 slightly-curved, minutely-serrated, bristles, mostly of a pale, semi- 

 transparent brown hue. These hairs are absent from the ventral 

 area. The whole surface of the pupa, except the w 7 ings and appendage- 

 cases, are closely studded with small star-shaped processes (lenticles). 

 The wings, and to a less extent the appendage-covers, have, in place 

 of the above, a closely- set netting of fine black veins. The colour is 

 dark umber, shading off into a pale red-brown. Traces of a black 

 dorsal band are present on the upper abdominal segments; this is 

 replaced on the almost black thorax with a mediodorsal band of red- 

 brown. The head and wing-cases are very dark, all but black at the 

 margins of the wings and the base of the haustellum, but lighter on 

 the ventral area, and towards the end of the antenna-cases and wings, 

 where the dark brown is much mottled and suffused with pale brown. 

 The prothoracic spiracles show up as raised, white, slit-shaped spots. 

 The haustellum-case and portions of two pairs of legs form the central 

 shield below the head, the tips of the former extending to about two- 

 thirds of the distance towards the tips of the antenme. The eyes are 

 rendered quite conspicuous owing to a portion of their surface being 

 so highly polished (Bacot, July, 190G). The pupa, is obese and moth- 

 like, without angles; the head rounded, and the anal segment incurved 

 and invisible from above. The cases, covering the head, antennas, 

 legs, and wings, are smooth, but not glabrous; they are without 

 hairs, while those covering the thoracic and abdominal segments are 

 hairy, the hairs for the most part standing out straight from the
