HOMALATTOIDES, gen. nov. 
Type H. roseus, sp.n., d. Panama. 
Leg i. incrassate in both sexes, but more strongly so in the male than in the female; tibia scarcely twice 
longer than broad, with 2—-2—2 spines in the apical half. Protarsi and tarsi in the female incrassate ; 
protarsus and tarsus i. longer in the male than in the female. ‘Tibiw and_protarsi iii. and iv. almost devoid 
of spines, with one or more at the apex only. Carapace square, convex, abruptly inclined behind the 
posterior row of eyes, somewhat excavate. Cephalic quadrangle of eyes much broader than long, wider 
behind. Small eyes one-third from the anterior laterals. Sternum twice as long as broad, oval, pointed 
behind, not produced between the coxe of the fourth pair of legs. Abdomen in both sexes coriaceous. 
It is possible that the species referred to this genus are congeneric with Homalattus, 
Adam White, Ann. & Mag. Nat. Hist. vil. p. 476 (1841), of which the type is 
H. pustulatus, White, from Sierra Leone. But for the present I have thought it better 
to describe the Central-American forms under another generic name. The three 
known to me may be distinguished as follows :— 
Males. 
A. Tibia i. not or scarcely more than twice as long as broad; carapace and 
abdomen clothed with violet iridescent scales, the abdomen coriaceous 
over the entire dorsal area. 
“4, Tibia i. scarcely longer than broad, with 2—2—2 conspicuous spines 
beneath. Carapace margined with a white band. Lower tooth of 
- mandible broad, but no large cusp. Apical spine of palpal bulb bifid, 
a longer inner spine and a shorter adjacent outer cusp . . . . . roseus, sp. D.
