ANYPHANA. 
Aena, Sundevall, Consp. Arachn. p. 20 (1888). 
Type A. accentuata, Walck. Europe. 
Anyphena can be distinguished from other closely allied genera, such as Aysha and 
-Arachosia, by the shorter, more parallel-sided maxille, and the straight posterior row 
of eyes. The spiracular rima is situated in the middle, or just before the middle, of 
the ventral area. The central anterior eyes are only slightly smaller than the laterals. 
The typical form, A. accentuata, Sund., has one pair of spines beneath the base of the 
anterior protarsi, while all those from Central America have two pairs of spines. 
The species are very numerous, and the males of many of them are remarkable for 
the conical protuberances on the coxe of one or more pairs of legs. 
The Central-American forms known to me may be recognized by the following 
characters :— 
Males. 
A. Coxe of one or more pairs of legs produced into a more or less 
conical prominence. . oo, 
i. Coxee of the first two pairs of legs only produced into a conical, 
dentigerous prominence, that of the first pair being the largest . simplex, O. P.-Cambr. 
ii. Coxe of third or fourth pairs produced into a conical prominence. 
a. Coxe of the second or third pairs, besides those of the fourth 
pair, of legs bearing prominences. 
1. Coxe of ii., iii., and iv. with prominences, that on i. being at 
the anterior apical angle; that on ii. in the same position, 
with a second elongate, curved appendage behind the first ; 
that on iii. at about the middle of the base. . . . . . tuberosa, sp. n. 
2. Coxe of iii. and iv. with stout curved processes springing 
from their base. Base of tarsus of palpus produced into a 
large conical spur above . . . . . . + + + + «+ « proba, O. P.-Cambr. 
b. Coxe of third pair only with a conical prominence towards its 
base. 
i. Tibial apophysis not divided into two branches. 
1*. Tibial apophysis broad, not curved at its base, bearing 
on the upper margin, about the middle, a short, sharp, 
triangular spur - . we eee ww ww ee «gtbba, O. P.-Cambr.
