Loc. Batjan. A single female example. 
An immature male, elosely resembling the female in all its characters and probably 
co-specifie with it, was taken at Patani in Halmahera. 
From its distribution this species might be expected to resemble 7. goramensis 
Thorell (Ann. Mus. Genova XVII, p. 269, 1892) from Goram in the Molucca group, but 
certainly differs from it in the following features. 
T. goramensis is considerably larger (20 mm), has the carapace, sternum, and legs 
black, the legs of the 1* pair three times as long as the carapace, and 5 pairs of spines 
on the lower surface of the first tibia and 4 on the 2=4, etc. 
Of the species known to me in nature, namely T. birmanica, Thorell, T. modesta 
Thorell, T. orichalcea Sim., and T. severa L. Koch, it most nearly approaches the first-named 
in size, but differs from it as from the others, in the shape of the vulva and the presence 
of 6 pairs of spines on the tibia of the 1* and 2X legs. It is true that modesta, from 
Penang, has 6 on the 1* tibia and 5 as a rule on the 22 tibia; but it further differs 
from flavipes in its larger size (20—23 mm), the presence of the scopula on the apex of 
the 1 and 2rdFtıbia, etc. 
Family Attidae. 
Genus Plexippus C. L. Koch. 
The term Plexippus is here applied in the sense in which it was used by Thorell in Ann. 
Mus. Genova, XXXI, p. 369 (1891—1892). 
Plexippus beccarüi Thorell. 
Ann. Mus. Genova, XVII, p. 582, ete. (1881). 
Four adult male examples, one from Ternate, one from Batjan and one from Tobelo, 
and another from Soah Konorah in Halmahera seem to be referable to this species, which 
has been recorded by Thorell from Ternate, Ceram, New Guinea, Aru und Cape York. 
These specimens differ considerably in size, length of palp, ete. as the following mea- 
surements show:
