The approxi nate formula is: 11,1 (2,3) 10 (8,9) 
(4, 7) (5, 6). All of the joints are furnished 
with hairs, those of the last being long and: most 
numerous. The legs are short and light brown in 
color. The joints of the first pair have the follow- 
ing lengths: coxa, 186; femur with trochanter, 
973 ; tibia 998; tarsus, QT “Claws, tot e nendigi- 
tules of the claw are short and filiform; those of 
the tarsus were not observed. There are at least two 
pairs of abdominal spiracles present, and possibly 
there are three pairs. The entire surface of the body 
is ornamented with innumerable dark hairs, some 
of which are very long while the others are shorter, 
and with innumerable small, circular, compound 
glands, flat on the external surface, and convex on 
the internal surface, with nine minute orifices in the 
margin and three in the central portion. The two 
eyes are small, dark brown in color, conical in 
shape, and are located near the insertion of the 
antenne. 
The eggs are elliptical in form, red in color. 
and have a smooth surface. The longitudinal diam- 
eter is about 0.837 mm. and the transverse about 
0.434 mm, 
The newly hatched larvæ are very active and 
red in color. The eggs observed in the laboratory, 
hatched in 32 days. On the second day, the larvæ 
had already secreted three tufts of wax on the 
dorsum, one entire on the abdomen, and two, longi- 
tudinally divided, on the thorax. Of these, the tuft 
on the metathorax, is the widest. The antennie are 
0.512 mm. long and are composed of six joints, of 
which the last is the longest. All of the joints are 
provided with hairs; the fourth and fifth joints also 
have one long hair each, and the last joint has seven 
very long hairs, besides the other shorter hairs. On 
the margin, between the antenna, there are two
