under which the spider takes shelter in the day time. One species, 
M. Syllepsicus (my catalogue) of a pale green color varied with black 
on the cephalothorax and abdomen, tips of the four anterior thighs with 
ablack ring, feet very hairy ; inhabiting damp woods. The legs and 
the eyes correspond with Epzira, but the trophi, except the mandibule 
are those of Tu&rrprum; and the web and habits participate of both. 
The long and slender mandibule are peculiar to this. ‘The cocoons 
resemble a plano-convex lens, are of a pale brown color, and are at- 
tached in the middle, one above another, in the tent which the spider 
inhabits. It is evident that in a perfectly natural arrangement, THE- 
kipivM should be placed near Eprira, and this genus between the 
two. There is a true Epeira, E. Labyrinthea, (my catalogue) 
which is found in the same locality and which makes a web of the 
same kind; and J at first suspected that this was a Taerm10m which 
had taken possession of the web of that Erzira, but, besides the 
character ftom the legs which does not belong to TaErrpium, the 
difference in the cocoons settled my doubts. The cocoons of the 
Errira above mentioned are nearly conical, of an obscure color 
above, whitish blue beneath ; they are hung in a string above the tent. 
The resemblance of habits in these two species, shows however the 
close affinity between the two genera and this.

legs variable, but the second generally the longest; lingua contract-

Tails, trees, &c. Eight species. This genus, embracing very differ-

of Walck., which have the two anterior pair of legs sensibly longer 
Po others. The other species ought to constitute other subdi-
