beneath and lateral spines as well; tibia and protarsi iii. and iv. also armed with long and numerous 
spines. Mandibles of the female stout, convex, porrect, and armed in front with two pairs of short 
bristles on the inner surface towards the base ; those of the male usually highly developed and elongate, 
with the pairs of bristles as in the female, and the fang very long and sinuous. 
The colour in nature is, by all accounts, bright grass-green, the cephalic area being often relieved by crimson 
tufts of hair. 
Members of this group are found in North, Central, and South America, in the 
Antilles, Madagascar, Ceylon, and Samoa. ‘They have been split up into various 
genera, of which we retain two only as likely to be permanent. These may be 
distinguished as follows, according to Peckham, for I do not know Asemonea :— 
GENERA. 
A. Cephalic ocular quadrangle never more than one-third broader 
than long. . . 2... Lyssomanes, Hentz. 
B. Cephalic ocular quadrangle at least twice broader than long . . Asgmonea, O. P.-Cambr.

Type: of Lyssomanes, L. viridis (on tab. 7 in Burgess’s work ZL. viridans), Hentz, North and South Carolina; 
of Jelskia, J. longipes, Tacz., Guiana ; of Maroussa, M. antillanus, Peckham, San Domingo. 
Eyes in four transverse rows of two each; first pair very large, three times the diameter of those of the 
second row; second pair separated nearly one diameter posteriorly from the anteriors; third pair very 
small, nearer to those of the second than of the third; fourth pair slightly larger than those of the second 
row ; eyes of the second row sometimes wider, usually as wide as or slightly narrower than those of the 
first row. Cephalic quadrangle of eyes sometimes slightly longer than broad, or broader than long, 
narrower behind. Ocular region high, obliquely vertical laterally. Sternum almost circular. Labium 
and maxille long, the latter dilated at the apex. Legs variable in relative length, 1, 2,3, 4; 1, 4, 3, 2; 
or 4, 1, 2, 3; ili. and iv. spinose. Protarsi i. and ii. with three pairs, tibia i. and ii. with two pairs of 
long spines beneath ; femora i. and ii. more or less spinose, and with three or four spines gathered round 
the apex; tarsal claws 2, claw-tuft present ; cox i. and ii. rather longer and stouter than iii. and iv. 
Spinners short, tuberculiform; posteriors longer and more slender than the anteriors; centrals almost 
obsolete. Mandibles of the male often very long, with elongate sinuous fang, similar in aspect to those of 
the genus Tetragnatha, of the family Argiopide; those of the female simple, with two pairs of stiff 
bristles meeting each other across the inner margin in front about the middle. 
The characters given in the following Table will serve to distinguish the species 
which are known to me :— 
Males. 
A. Upper inner margin of fang armed near its base with a more or less 
developed tooth or spur. 
a. Fang-tooth more remote from the base, not highly developed. 
(Tibiz and protarsi of legs i. and 11. not clothed with distinct 
fringes of black hair. Tibia of palpus with a distinct isolated
