10 Prof. Westwood on various species of the 
in many there depends a pointed portion of the egg- 
cover (fig. 2), although it is evident, from Dr. Brauer’s 
figure of a separate egg and his description, that the 
young larva escapes by detaching a cap at one end of 
the egg (fig. 3). I am unable to explain the cause of 
the lateral aperture and detached portion of the egg- 
cover. 
Fig. 4 represents a group of young larve of the 
Ceylonese species from a sketch by Mr. S. Green, repre- 
senting a row of the insects sitting along a twig close 
behind one another, with the jaws widely expanded. 
Fig. 5 represents a very minute larva found in the 
bottle of spirits which contained the full-grown larve 
and imagos. It is represented much magnified in fig. 6, 
showing the very large head, very short prothorax, 
nearly circular body. The front of the head is emargi- 
nate in the middle, with a row of short clavate setx 
along the edge. The antenne (fig. 7) are filiform and 
consist of about twenty-two joints, the basal ones of 
large size, and the apical one slender and much longer 
than the penultimate one. The ocelli are six on each 
side of the head, placed in a circle upon a strong pro- 
jecting peduncle. There are twelve projecting setose 
lobes on each side of the hind segments of the thorax 
and abdomen. The sete, which are thickened to the 
tips, arising from dilated portions of integument in a 
curious manner, are represented in the different figures 
8 to 12, drawn under a high power. 
Fig. 13 represents the full-grown larva, 73 lines long, 
exclusive of the jaws. The head is deeply emarginate 
both anteriorly and posteriorly ; it is depressed, finely 
setose, or villose. The antenne (fig. 15) are very 
slender, except the two basal joints, and they are 15- 
jointed, the last joint very slender, with apparently a 
very minute terminal articulation, which bears three 
short sete at its tip. Fig. 14 represents the side of the 
front portion of the head, which bears the ocelli, having 
a row of marginal sete before the ocellar peduncle, the 
sete being thickened at the tips. Fig. 16 represents 
one of the legs, of which the coxe are long and 
cylindrical, giving much liberty of motion to the limb; 
the tarsus is composed of a single point, having two 
nearly straight ungues at its tip. The body is smooth, 
finely villose, destitute of the flattened lateral lobes seen
