4,2, TEPHROSIA EXTERSARLIA. 
Pupa of ordinary shape, a little less than half an 
inch in length, stout, slightly rough, but glossy; the 
head-, eye-, leg-, and wing-cases dull olive-green ; 
abdominal segments reddish brown, with darker spots 
and segmental divisions. 
The moths emerged from May 20th to 28th in the 
spring following. (George 'T. Porritt, January 5th,

1 received a few eggs of this species, together with 
the parent moth, from Mr. J. R. Wellman, of London, 
on June 14th, 1876. ‘They were oval, and of a dingy

mental divisions well-defined, and each segment rather 
numerously divided transversely into sections, which 
give the skin a somewhat rough appearance. 
Ground colour a bright apple-green, the head tinged 
with yellow; two yellowish-white lines, having a 
yellowish pulsating line between them, form the dorsal 
stripe; subdorsal lines yellowish- white, and there are 
two other lines of the same colour, but much finer and

segmental divisions yellow. 
The ventral surface is of the same colour as the
