early stages of Latiorina orbitulus. 151 
its very shining and polished skin adding much to or almost causing 
this illusion. The head and legs are black.” 
The form of the larva is the usual Lycaenid one, up to 
14 mm. long and 3 to 4 wide, according to the amount 
of stretching out; a trifle wider anteriorly, but of nearly 
uniform width from the mesothorax to the sixth abdominal. 
The 7th to 10th abdominal are perhaps a little less fused 
together than usual in Lycenids. Each segment rises 
dorsally into a low arch, and the lateral margin (seen 
dorsally) is a series of slight curves. The remarkable 
feature of the larva is the absence of a honey-gland. 
On July 4 several larvae had suspended themselves 
on the side or lid of the box for pupating. The carpet of 
silk is slight, the cremastral pad hardly stronger than the 
rest of the carpet, and the girth consists of half-a-dozen 
threads nearly all separate, and arising from a scattered 
base, but connected together near it by a few cross 
threads. The whole arrangement is very slight and flimsy 
and quite unequal to bear the slightest strain. 
As the larva approaches pupation the colours get duller, 
the pink almost disappears and the white gets dim. The 
brown dorsal line with a little white near it, the oblique 
brown dashes of the slope and the brown lateral lines are 
all much of a tint. The lateral line is lost on the thorax 
(owing to wings beneath) and the thoracic segments, 
especially the mesothorax, become larger. The head is 
quite sunk in the prothorax, the thorax is nearly one-third 
of the total length. 
On July 10 the first specimen pupated; immediately 
on pupation the pupa is of the same brilliant colours as 
the larva at its best, not the dull ones immediately pre- 
ceding the change ; the oblique lines are Jost on the thorax, 
but the white lateral line, with broad, pink band above 
and brown below, is very distinct, even where covered by 
the wings, which are quite transparent. After some hours 
the thorax and wings become of a bluish-grey (leaden 
lavender), the abdomen almost yellow rather than green, 
but very pale. The red dorsal line very narrow on thorax, 
but spreading along front of prothorax, head colourless 
(transparent glassy green). Tracheal nervures of wings 
very distinct in the transparent tissue. It may almost be 
called hairy, with short white hairs most numerous 
anteriorly and posteriorly.
