2. The transverse space occupied by the anterior row of eyes 
not wider than that occupied by the central posterior pair. 
Central posteriors much further from each other than 
from the laterals, much more than one diameter apart. . Enna, O. P.-Cambr. 
ii. Tarsi very long, slender, and flexible. 
a’. Legs 4, 2,1, 3. Anterior row of eyes recurved. Tibiz i. and 
li. with 5 pairs of spines beneath, the last pair small and 
apical. Protarsi i. and ii. with 4 pairs of spines beneath. . Trecwauua, Thorell. 
6’. Legs 4, 2, 3, 1. Anterior row of eyes straight. Tibiz i. and 
ii. with 9 or 10 pairs of spines beneath, the last pair not 
apical. Protarsii. and ii. with 8 or 9 pairs of spines beneath. Syn rRECHALEA, gen. nov. 
Norr.—The spiders here included under Tinus appear to be very nearly allied to Drances, K. Simon * ; but 
in the description of that genus it is expressly stated that the small apical spines beneath tibie i. and ii. are 
absent. In mentioning the height of the clypeus in Thawmasia and Drances, two very closely allied genera, 
M. Simon compares it with “area oculorum mediorum” in Zhawmasia, and “ oculis mediis anticis” in 
Drances. It is impossible to compare the characters of the genera from such definitions. nna is, so far as one 
ean gather, identical with Hesydrus, Simon (Sect. 2"). The type, H. palustris, Simon, belongs to Sect. 1°, 
so that the spiders under Sect. 2* have no generic name. 
CUPIENNIUS. 
Cupiennius, E. Simon, Bull. Soc. Zool. Fr. xvi. p. 109 (1891). 
Type C. getazi, KE. Simon. Costa Rica. 
Tarsal claws 3. Tibie i. and ii. with four pairs (2—2—2—2) of spines beneath, including the apical pair ; 
also two lateral spines on each side (1—1) in both Q and g. No dorsal spines on tibie 1., ii., iii, or iv. 
No spines on patellie i., ii., iii., or iv. 2, present oni., ii., ill. ¢. Protarsi i. and ii. with three pairs 
(2—2—2) of spines, and i i., ill., iv. with a single, small, stout spine at the apex, beneath. Legs 1-2, 
4,3. Lower margin of fang-groove with four teeth, upper with three. Second row of eyes procurved. 
Lateral anteriors midway between posterior centrals and posterior laterals in the 9, much nearer the 
former inthe ¢, but not in the same line. Central anteriors one-third smaller than posteriors. Ocular 
quadrangle as broad as long, much narrower in front. Clypeus equal to one and a half diameters of 
anterior centruls in 2, one diameter in g. A thick scopula present beneath tarsi and protarsi i. and ii., 
and apex of protarsus iii., absent bencath protarsus iv., present beneath tarsi iii. and iv. Patella and 
tibia i. much longer than patella and tibia iv. 
The species known to me may be distinguished as follows :— 
Males. 
A. Size larger: total length 32 millim., carapace 14 millim. Femora i., ii., 
iii., and iv. with a median pair of dusky blotches (sometimes perhaps 
obsolete). Central unca of palpal bulb evenly rounded behind. 
Abdomen with a broad, black, ventra] band . . . . . « . gallei, Keys. 
B. Size smaller : total length 15-20 millim., carapace 6°5-7 millim, Femora 
of legs unicolorous, not blotched beneath with black. Central unca of 
palpal bulb much produced behind. Abdomen either without or with a 
very narrow, central, dusky band . . » foliatus, sp. n. 
* The name Drances, Simon (1898), is preoccupied in Coleoptera (1889).
