and has three slight lobes on each side. The antenne are 
short and thick, about ‘093 millim. long, and apparently 
composed of four segments. ‘The last joint has several short 
terminal hairs. ‘The mentum and rostrum are well developed 
and close to the antenne. Rostral loop short. The two lac- 
glands are large and have the opening guarded by six or more 
short sharp spines. Near the lac-glands there are two large 
spiracles that have forty to fifty round spinnerets about the 
external orifice. Near the rostrum there is another pair of 
smaller spiracles. The legs are sometimes present as small 
sharp tubercles. ‘The dorsal horn is strong and _ straight, 
blunt, *110 millim. long. Anal ring with ten long hairs. 
Around the anal ring, and enclosing it, there is a chitinous 
horn or collar, which bears twelve short plates; these plates 
may vary in number. ‘The sides are nearly parallel and the 
ends finely serrated. The collar bears many minute tubercles 
and several short hairs at the base. On the dorsum, between 
the collar and the dorsal horn, there are four tubercles, each 
one bearing fifty to sixty large round spinnerets. On the 
ventral surface, near the antenne and spiracles, there are four 
groups of about fifteen small elongate glands each. ‘The 
derm bears a few spinnerets and small hairs. Length 2 
millim.; width 1°50 millim. 
Larva (just hatched).—Small, elongate, dark purple, 
almost black. Antenne of six joints; joint 6 the longest, 
joint 3 the next longest, joint 5 bears two very long hairs. 
Rostral loop long. “Legs slender, long; tarsus and claw each 
with a pair of digitules. The body ends in two very long 
sete, at the base of which are several short spines. Between 
these is the chitinous ring, bearing six or eight processes. 
Within this ring is the anal ring, which bears six hairs, 
There is a notch on each side on the prothorax, in which are 
situated the large spiracles. ‘lhe openings of these spiracles 
are furnished with about ten round spinnerets. On each side 
of the dorsum there are three or four longitudinal rows of 
small tubercles, each one ending in a hair. On the ventral 
surface there are two longitudinal median rows of short hairs.

‘The insects are usually found singly on the underside of 
the branches. Sometimes the lac of two or three individuals 
will fuse.
