similarity between them and the subdivision Syivarra (Walck.) of 
Dotomepes, in point of manners and habitus. The three species 
of Spuasus, known to me, wander in quest of prey about the trunks 
of small trees or upright sticks, move with great rapidity, and when 
at rest, spread their fect like many species of ‘T'Homtsus. On the 
first of September, a large female was brought to me in a glass ves- 
sel. call it Spuasus viridans. It is of a pale grass color, with 
the disk of the abdomen yellowish, except an oblong longitudinal line 
in the middle, which has a double row of three or four oval oblique 
yellow spots, separated by a longitudinal blackish line ; feet pale with 
yellow joints. Length 0.81 ofaninch. It was impregnated and with 
eggs. After a few days, it made a web of very strong threads, like 
that of Tuerrprum, in the middle of which was placed its cocoon, 
which is perfectly conical, made with great exactness, and is supplied 
around with little mammule from which depart the threads whieh 
bind it tothe web. The mother watched it constantly, and never 
left it as long asshe lived. The young were hatched on the 14th 
of October and continued together for many weeks during the wi- 
ter, but gradually died; they were of a deep orange color and full 
0.9 of an inch in length. The mother had previously been destroy- 
ed by an accident, which I regretted very much, for I have some 
reasons to think that the young are carried on the back of the mother 
as in Lcosa, and wished to have ascertained that fact.

me a species, the female of which constructs a web not unlike that 
of Tecenarta ; but that retreat is limited to one sex, and probably 
_used only to protect the cocoon, until the young are hatched, and 
able to go abroad.
