hardens, and segmentation becomes very distinct. Two 
breathing spiracles also develop on top of the head. When 
fully developed the pupa is longer and thinner than the 
larva, the wing-pads are short, the abdomen is considerably 
flattened, and shows distinct ribbed segmentation. On 
January 7, a number of larve were placed in moist sand, 
and the adults emerged on the 24th of same month. 
- LIFE-HISTORY OF BUTTERFLY, EUPLOEA 
; . CORINNA. 
By L. Gallard. 
This butterfly, though rarely found as far south as 
Sydney has been rather plentiful about Epping in 1918. 
During March and April I collected larve and pupx in, 
numbers on the White Runner (Mandevillia), The larva 
is a rather slender banded caterpillar, somewhat resembling 
that of Danais menippe. Tt has eight erect fleshy append-

of a bright metallic silvery sheen, which, however, becomes

fish-like form (as befits the aquatie environment), but in 
nowise related to fishes. Unlike that of the fish-form, the
