COBANUS.—AMYCUS. “191 
at a glance to distinguish between this species and Amycus quadriguttatus, but the 
-spinulation of the first pair of legs will determine the genus at once. The male may 
be recognized by the fact that the mandibles are normal, as in the female, not 
‘ elongated. : 
5. Cobanus subfuscus, sp.n. (Tab. XIV. figg. 4, 4a, ¢.) 
Type, ¢, in coll. Godman & Salvin. Total length 6°5 millim. 
Hab. Costa Rica (Sarg). 
This species may be known by the yellow legs, the first pair darker, and the dark 
-olive-green colour of the dorsal area of the abdomen. ‘The mandibles are normal, 
but the two pairs of teeth are not opposite each other. If it were not for the 
coloration and the shape of the tibial spur of the palpus, the form of the mandibles 
might indicate that C. subfuscus was a variety of one of the other species, but, pending 
the receipt of further material, I prefer to treat it as distinct. 
6. Cobanus perditus.

The figure and description are not sufficiently detailed to enable one to judge of 
either the genus or species to which this spider belongs. 
TITANATTUS. 
Titanattus, Peckham, Proc. Nat. Hist. Soc. Wisc. 1885, p. 62 (Dec.). 
Type 7. sevus, Peckham. Guatemala. 
This genus is very closely allied to Amycus, differing only in the greater curvature of 
the first row of eyes.

AMYCUS. 
Amycus, C. L. Koch, Die Arachn. xiii. p. 182 (1846). 
Type A. spectabilis, C. L. Koch. Brazil. 
These characters are drawn in the main from A. benignus, Peckh.:—Male. Anterior row of eyes recurved by 
their posterior margins; centrals twice the diameter of the laterals. Clypeus variable in size, from 
equal, to almost twice the diameter of, an anterior central eye, concave. Cephalic quadrangle broader
