Clubiona, Latreille, Nouv. Dict. Hist. Nat. xxiv. p. 1384 (1804). 
Elaver, O. P.-Cambridge, Biol. Centr.-Amer., Arachn. Aran. i. p. 288 (1898). 
Type of Clubiona, C. pallidula (Clerck), Europe; that of Hlaver, E. tigrina, O. P.-Cambr., Mexico. 
Carapace with the central stria distinctly marked. Central anterior eyes not or scarcely larger than the 
laterals. Posterior pair of spinners with a very short (sometimes longer) conical terminal segment. 
Posterior row of eyes procurved, centrals more remote from each other than from the laterals. Upper 
margin of fang-groove with 3 or 4 teeth, one being much larger, lower margin with 3 or 4 unequal teeth: 
the number varies, often being different on the right and left falx in the same individual. Colulus 
absent, or marked by a group of hairs only. Anal tubercle very distinct. 
The structural details of the type of the genus, C. paliidula (Clerck), are figured on 
Tab. VI. figg. 18, 18 a—-c ( @ ). 
Males. 
A. Tibiz i. and ii. with 2—2—2 spines beneath, the third pair apical and 
very small. 
i, Tibia of palpus more than four times loriget than broad, with a 
short blunt spur at its base above. Tibial process tridendate; the 
basal tooth very large, uncate, the other two teeth much smaller. 
Bulb with a sharp spur at the base on the inner side. 
ii. Tibia of palpus not more than three times longer than broad, 
without short basal spur above. Bulb without any sharp spur at 
the base on the inner side. 
a. Tibial spur very long, longer than the tibia itself, and deeply 
bifid at its apex ; 
b. Tibial spur comparatively short, less than half the length of the 
tibia. 
1. Tibial spur very short, terminating in two sharp, stout, 
divergent spines Sie ew pe ke 
2. Tibial spur longer, triangular, and more or less dentate. ¢ 
a. Tibial spur with three dentations ; the apical one very long 
and sharp, the second shorter, the third very minute 
6. Tibial spur with five dentations . . een 
B. Tibie-i. and ii. with 2—2 spines beneath; no apical pair. “Tibia of 
palpus not longer than broad. Mandibles excavate on the inner 
margin ot 
Females * 
A. Abdomen with very distinct pattern: a central posterior dorsal row of 
triangular spots, with slender lateral branches, with oblique lateral 
bars, sometimes coalescent. Protarsi and tarsii. and ii. dark brown. 
a. Central tongue of vulva short, broad, not narrowed at its base, 
scarcely reaching to the middle of the total length of the vulva

* The types of C. mordica and C. placida, O. P.-Cambr., are not sufficiently developed to enable me to 
tabulate their characters satisfactorily.
