and has three slight lobes on each side. Tiie antennae are 

 short and thick, about "093 niillim. long, and apparently 

 composed of lour segments. Tlie last joint has several short 

 terminal hairs. The mentuni and rostrum are well developed 

 and close to the antennai. llostral loop short. The two lac- 

 glands arc large and have theo))ening 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. 'Ihe dorsal horn is strong and straight, 

 blunt, '110 millim. long. Anal ring with ten long hairs. 

 Around the anal ring, and enclosing it, tiiere is a chitinous 

 horn or collar, which bears twelve short plates; these plates 

 may vary in number. Tiie sides are nearly parallel and the 

 ends finely serrated. 'J'he 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 antenna 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 l"oO millim. 



Larva (just hatched). — Small, elongate, dark purple, 

 almost black. Anteimaj of six joints; joint 6 the longest, 

 joint 3 the next longest, joint 5 bears two very long hairs, 

 llostral loop long. Legs slender, long; tarsus and claw each 

 with a pair of digitules. The body ends in two very long 

 setit, at the base ot which are several short spines. Between 

 these is the chitinous ring, bearing six or eight processes. 

 ^Vithin 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. The 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 tiie ventral 

 surface there are two longitudinal median rows of short hairs.
