302 BRITISH BUTTERFLIES. 



July 12th, at about noon. The ventral part of the newly-formed pupa 

 is of a whitish tint, with a faint internal tinge of green in the neigh- 

 bourhood of the maxillae, the tips of which project, at present, freely 

 beyond the apices of the wings ; the wings, too, are translucent greenish- 

 white, the underlying red of those parts of the lst-4th abdominal segments 

 that they cover showing distinctly through them . The prothorax is bright 

 crimson, the glassy eyes and mouth-parts being of the white trans- 

 lucent tint of the venter ; the mesothorax looks more or less shiny 

 translucent, with a somewhat corneous appearance, of a much paler 

 tint than the prothorax, whilst the dorsum of the metathorax and of the 

 abdominal segments are again of a bright red (almost crimson) hue ; the 

 incisions of the abdominal segments are much deeper red than the body 

 of the segments both laterally and ventrally, and this difference between 

 the colour of the incisions and that of the rest of the segments is marked 

 to the metathorax, even through the translucent wings. The dorsum shows 

 distinctly a fine, deep-seated, dark red, mediodorsal line from the front of 

 prothorax to abdomen, and, on the 2nd-6th abdominal segments, the pale 

 oblique lines stand out conspicuously above the spiracles, finely edged 

 with darker reddish below, and enclosing a dark dorsal area between their 

 upper ends — appearing like a broadish dorsal, almost crimson, band, 

 looked at from above. As soon as changed, the newly-formed and 

 soft pupa lifts itself slowly by its anal segments, stretching its head 

 somewhat forward, and, by a slight backward movement, pushes, as it 

 were, the wings farther down over the 4th abdominal segment, but these 

 movements soon cease, and it shortens somewhat and rapidly attains its 

 natural squat form. Another pupa was observed maturing its colours 

 (after apparently pupating in the early morning of July 17th) about 

 noon. Its abdomen is of a deep plum-red, the upper row of oblique 

 lines subcutaneous and a shade paler, the spiracles somewhat ochreous, 

 each situated in a slightly pale brownish subcutaneous patch. The 

 mesothorax is getting brown, whilst, underlying all the thoracic and 

 abdominal parts dorsally, there are a number of subcutaneous blackish 

 dots . The wings are of a som ewhat pale brownish tint , like the m esothorax , 

 but the inner marginal area, to the anal angle, and the middle of the 

 wings, have a distinctly green tinge yet ; the w T ings also are thickly 

 dotted with small, blackish, subcutaneous spots. Prideaux notes (in litt.): 

 " The freshly-formed pupa has much the same colouring as the larva 

 directly before pupation, the dorsal and abdominal parts being flesh- 

 mauve colour, with translucent green wing-cases. Subsequently, the 

 pupa is yellowish-brown, mottled and speckled with darker brown. 

 Except about the head and wing-cases, and over the anal area, the 

 pupa is covered rather sparsely with short glassy bristles, in some, but 

 not in all, cases, these bristles possess very delicate, white, lateral 

 spinules, such being specially observable in the spiracular regions." 



Pupa. — The pupa of this species is paler, and gives the impression of 

 being of more delicate texture, than those of Edwardsiaw-album t Callophrys 

 rubi, Bithys querents, etc. The second impression is that it is without 

 hairs ; this is not quite the case, but the hairs are very small and very 

 few. The consequence is that the network, with the points at the 

 intersections, is less interfered with, and forms a continuous ornamen- 

 tation over a large part of the pupa. The points are small circles, of 

 the same dark chitin as the ribs of the network ; the centre of the circle 

 contains a disc of paler chitin, in which is a central colourless point,
