Eqgs.—Length scarcely 3mm. Regularly oval cylindrical, being rather long. The 
surface coarsely pitted, and under a half-inch objective seem to be marked with 
deep, well marked, close-set pits which are rounded at the bottom with distinct five- 
sided edges or rims. They are laid either scattered or in rows of three or four, not 
placed exactly end to end, but with one end directed a little to one side of the line. 
Freshly hatched larva.—Length, 3-4 mm. Body of the usual Geometrid shape, not 
being swollen on the thoracic segments. The head is of moderate size, slightly 
wider than the body, and of the same reddish-brown color as the body; it is spotted 
with white in front, with two white spots above transversely arranged, and two 
large ones on the clypeus longitudinally arranged. The body is long and slender, 
dark reddish brown, marked with bright white irregular patches. Prothoracic seg- 
ment with a large white oval spot next to the head, and a white dot on each side, 
the two succeeding segments reddish-brown with no marks. The first six abdominal 
segments each with a large white triangular showy spot on each side and meeting 
above. Each spot is composed of several large flat warts. Theside of the suranal 
plate is lined with white, and the sides of the anal legs bear several flattened white 
warts. All the legs are dark. The abdominal segments each bear a few scattered 
short glandular hairs which are swollen at the end and divided into three lobes. 
The larve were not carried on to the second stage. One freshly hatched larva was 
observed September 6 which only measured 2 mm. in lengh. 
Stage III ?—Length 10mm. The larva now resembles in shape and markings the 
full grown insect. The head is dark brown, with four longitudinal whitish stripes. 
The body is dark brown with indefinite, fine, longitudinal, blackish lines. Behind 
the thoracic segments the two basal abdominal segments are swollen forming a bar- 
rel-shaped enlargement with no white markings on this portion. Behind, in the 
middle of the body, are four sets of whitish yellow or tawny marks arranged at nearly 
equal distances apart, two slashes on each side, with a third oblique line passing 
over the back and nearly meeting the one from the other side; the ends on the back 
being sienna-brown; and between their points the faint yellowish white or tawny 
linear dorsal line is more distinct than elsewhere, the line not reaching the swollen 
anterior part or the posterior end of the body. Described September 2. 
Full-grown larva.—Length, 20mm, The head is a little flattened in front, slightly 
wider than the prothoracic segment. The body is much swollen on the first and 
second abdominal segments, so as to be twice as thick as in the middle or as the rest 
of the body. The thoracic segments increase in size towards the swollen portion 
behind, but the third abdominal segment is of the same thickness as those behind it. 
The body is of a rich velvety brown-blatk, with a broken light dorsal line, which is 
most distinct over the sutures. On each side of abdominal segments 3 to 6 are three 
oblique white slashes, forming very conspicuous marks; two of the slashe nearly 
meet above, near the sutures. The head is dark, with two lateral white stripes con- 
tinued back upon the first and second thoracic segments. The body elsewhere is 
faintly striped. The swollen portion behind the thoracic legs, and the dark-brown 
body with the four sets of three conspicuous white slashes, render it a very curious 
and conspicuous object. It may resemble a twisted dead or blackened portion of a 
leaf, or leaf-stalk, and it may have acquired the swollen appearance as a terrifying 
_ or deterrent feature. The young larva when 10 mm. long holds itselfup much looped, 
supported by its anal legs, and sways itself to and fro sideways, and if one touches 
another it will strike at the other, simulating the actions of snakes when striking 
at an assailant. ‘ 
Pupa.—Length, 12-13 mm. The head in front projecting forward, with two low 
conical piliferous tubercles. Two small dark tubercles at the base of the antenne, 
and two larger ones in the middle of the-head between them. Towards these tuber- 
cles the back of the thorax slopes evenly down, so that an angle or ridge is formed 
extending across the thorax between the insertion of the fore wings. The body is 
pale ash-gray , with a greenish tinge on the thorax. The abdomen is slender, conical,
