THE WEEKLY ENTOMOLOGIST. 
to be found. When, however, the 
parts are separated, we find that the 
mandibles are represented by two 
sharp spines, by which the skin of 
the victim is pierced. They are 
ribbed and serrated at their edges, 
one of which is thick and horny, 
while the other is of a more delicate 
texture. The maxillae, maxillary 
palpi, labium, and labial palpi, are all 
present in an elongated form. We 
might multiply cases of homology 
without end, did space permit, but 
we will now conclude by enquiring 
what is the significance of homo- 
logy ? Not, we should reply, what 
the Darwinian would tell us, that 
these various forms of structure had 
a common origin, but rather that 
there is design in creation, which 
delights in combining the richest 
variety of form with the utmost 
unity of conception.

OBSERVATIONS. 
Lepidoptera. 
Larva of C. curtula. — The follow- 
ing is a description of this larva, 
which I have been rearing from 
eggs kindly supplied by Mr. Porteous 
of York : — 
Length, when full fed, about H 
inch, yellowish white, powdered and 
spotted with black. On each side 
of each segment above the feet are 
two bright yellow spots, one above 
another, which are almost confluent 
from segment to segment, and give 
the appearance of two yellow lines 
on each side. In the centre of each 
spot is an orango wart, from which 
proceed small groups of thin whitish 
hairs. T hese warts are most visible 
on the first six segments ; and on 
the first t wo or three segments the
