~ Pupae of Lepidoptera, chiefly Lycaenidae. 487 
of the structure as found in Callophrys rubi. T is the 
papilla, P the position of the surviving hooks of the proleg, 
M is the muscular tissue, F the fat body, H the hypoderm,

separate organ, but is, as already indicated, a diverticulum 
of the cuticle. Incidentally the section supports the view 
that it is the inner half of the hooks which persists.

Amongst the specimens sent home by Mr. Farquharson 
is a Geometrid larva which he describes as having the 
appearance of a small centipede. Unfortunately it was 
TE ae 
not on its food-plant and was the only example found by 
him, so that there is no means of identifying the species. 
The example I have figured is about 15 mm. in length. 
It was evidently undergoing a moult as parts of the old 
cuticle became detached on touching it. Text fig. 5, A 
shows a dorsal view. ‘The first two segments are expanded 
and flattened, fused together, and dorsally slightly concave.

pair of spiracles, which are black and so placed as to resemble 
eyes. The 3rd segment is more or less normal, but the 
4th to 8th inclusive have large lateral expansions. The
