Epicadus, E. Simon, Hist. Nat. Araign. (2) i. p. 1052 (1895). 
Type E. heterogaster (Guérin). Tropical America. 
No representative of this genus has yet been taken in Central America, but since 
some are sure to be discovered in the tropical regions, such as Panama, the characters 
are inserted in the Table and figures of them in the Plate [Tab. X. figg. 34, 34a-c 
(@)]. They will also prove useful for comparison with those of closely allied genera. | 
ONOCOLUS. 
Onocolus, E. Simon, Hist. Nat. Araign. (2) i. p. 1053 (1895). 
Type O. echinatus (Tacz.). Cayenne. 
Legs comparatively short, stout, and compressed ; tibie, protarsi, and tarsi more or less incrassate. Protarsi i. 
and ii. with 2—2—2, tibie with 2—2—2—2, spines beneath, no laterals. Anterior row of eyes strongly 
recurved ; posterior row straight. Carapace scarcely longer than broad. Anterior lateral eyes distinctly 
larger than centrals. Femora not incrassate, nor tuberculate on the dorsal surface. Carapace and body 
very much compressed ; ocular area produced somewhat conically behind the anterior lateral eyes. Two 
bisegmentate spines are situated just behind the middle between the anterior central eyes. 
The basal segment in the male is much longer in proportion than in the female. 
The tibial and protarsal spines are much longer than in the allied groups and are 
enclosed in a basal socket, hinged and capable of being raised and depressed. 
The body and legs, in both sexes, are clothed with so-called sensory hairs, of various 
sizes and types, consisting of a stouter chitinous basal sheath and a longer or shorter, 
a stouter or more slender, movable terminal sensory segment. ‘The bulb at the base 
of this terminal portion is distinctly seen to be connected by muscles and nerves 
with the body-tissues, through the cylindrical basal sheath. Colulus absent in both 
SeXes. 
Four or five species only, which fall into this genus, have been recorded, and all from 
the Neotropical region :—0O. echinatus (‘Tacz.), O. pentagonus (Keys.), O. compactilis, 
E. Sim., O. stolzmanni (Keys.), and another, undescribed, taken by the author on the 
Lower Amazons.
