hairs, which are weakest and least numerous in the first and last 
segments, the seventh (counting from the middle line) being iden- 
tical, at least in position, with the lateral hairs of other species. 
On the eighth and ninth abdominal segments these hairs are all so 
small as to be scarcely noticeable among the well-developed pile 
with which the body is covered. The pile is associated with 
minute spinules, of which one is situated immediately in front 
of the base of each of the fine hairs of which the pile is composed. 
In front of the lateral ends of each line of long hairs the pile is less 
dense and the spines are relatively large and sharply pointed. In 
the smaller of the two specimens part of this area is entirely 
without hairs and spines. The tenth abdominal segment bears 
the usual circumanal ring. 
Aceraius pilifer (Percheron). 
Locality.—Sarawak : Kinabalu, 4500 ft. 
Two specimens 30 and 37 mm. long respectively. The head 
resembles that of the larger of the two specimens of the preced- 
ing species. The pile on the thorax and abdomen is much longer 
than in that species, and is accompanied by somewhat finer spin- 
ules; otherwise the thorax and abdomen resemble those of that 
species. 
Aceraius helferi, Kuwert. 
Locality.—Tenasserim: Misty Hollow to Sukli, Dawna Hills, 
ca. 2100-2500 ft. 
Four specimens, each about 38 mm. long. The head resem- 
bles that of A. grandis subsp. hirsutus. The pairs of dorsal hairs 
are three in number as in that species, but are present on the 
thoracic as well as on the abdominal segments, and are accom- 
panied on each of these segments by a pair of lateral hairs. On 
the first thoracic segment they are also accompanied by a few long 
hairs in the anterior angles, and on the ninth abdominal by a pair 
of well developed ventral hairs. The tenth abdominal segment 
bears the usual circumanal ring. The pile is short asin A. grandis 
subsp. hirsutus. 
Macrolinus andamanensis (Stoliczka). 
Localities. Andamans: Port Blair; Bom lungta (from Popita 
tree). 
Four specimens, all about 30-32 mm. long. ‘The head is cov- 
ered with fine hair, but bears no long hairs either behind the 
antennae or elsewhere. The body is covered somewhat closely 
with short pile. The thoracic and seventh to ninth abdominal 
segments are without hairs. The first six abdominal segments 
have two pairs of dorsal hairs as in Episphenus indicus, from 
which species the present one may be distinguished by the
