THOTMES.—HABRONATTUS. 241 
Hab. Guatems.a® (Sarg).—Evrope, Mediterranean region!24; Maay ARCHI- 
PELAGO; AUSTRALIA. 
A cosmopolitan species. One cannot believe that it is congeneric with MW. semi- 
limbatus, the type of Menemerus, Simon. 
2. Thotmes fanne. (Tab. XX. figy. 22, 22a, ¢.) 
Menemerus fanne, Peckh. Occas. Papers Nat. Hist. Soc. Wise. ii. 1, p. 74, t. 6. figg. 6, 6 a-c (¢) 
(April 1896) *. 
Type, 3, in coll. Peckham, Total length 6°8 millim. 
Hab. GuateMALa !.—Souta America, Colombia!. 
Judging from Emerton’s figure of the palpus 1, this species appears to me to belong 
to Heraclea, Peckh., which I cannot at present separate structurally from Cyrene. 
If, however, Peckham is correct in supposing it to be congeneric with Attus paykulli, 
Aud., then M. fanne will fall under Thotmes. 
3. Thotmes bicolor. 
Menemerus bicolor, Peckh. Occas. Papers Nat. Hist. Soc. Wisc. ii. 1, p. 175 (April 1896) ’. 
Type, d, in coll. Peckham. Total length 5-8 millim. 
Hab. Guatemata, Eastern district }. 
No figures are given of this species, nor any mention made of the structure of the 
palpus, nor as to the specimen being adult or otherwise. Whether it belongs to 
the genus Hasarius, which has H. adansoni for the type, I cannot say, for Peckham 
holds that this type-species appertains to the same group as Phidippus, a classification 
I cannot understand, since he supposes it to be congeneric with Attus paykullt. For 
the present, J. bicolor can be left under Thotmes. 
HABRONATTUS, gen. nov. 
Type Habronattus meaicanus (Peckham). Mexico. 
g. Cephalic quadrangle of eyes much broader than long, slightly wider behind ; small eyes nearer the 
posterior laterals. Anterior row straight by the posterior margin ; laterals one-half the diameter of 
the centrals. Mandibles normal, not developed, with one tooth on the lower margin, three on the upper, 
very close together. Patella iii, usually produced into one or more differently shaped spurs. Legs 
3, 4, 1, 2 in both sexes, Tibia i, with 2—2—2 spines beneath, the inner spines of the basal two pairs 
peing in the type-species (H. mewicanus) long and clavate. Protarsus i. with 2—2 spines beneath, no 
laterals. Legs iii. and iv. very spinose ; protarsi with three rings of spines, a basal, median, and apical 
group ; tibie iii. and iv. with a small dorsal basal spine. 
°. General characters similar to those of the male. Vulva with always a smaller or larger central transverse 
chitinous rim, marking the upper margin of a central orifice.
