DESCRIPTION OF GENERA AND SPECIES. 205 
Aspomen: About one third longer than wide, rectangular-oyate, the form difficult to 
describe. The dorsum appears to be flattened or concave, and provided on the margins 
with a series of conical protuberances, which terminate in points more or less blunted. 
The shoulder humps are bifid, one of the projections terminating in a long, curved, 
corneous point, something like the horns of a cow. The apex is about as thick as the base, 
the spinnerets distal, but overhung by the projecting and tuberculated apex. The dorsal 
surface is thickly covered with short golden yellow hairs; about the middle on each. side 
rises one pair of horns, beneath which, upon the sides and a little posterior, is another 
process projecting laterally. The apex of the dorsum is divided into at least four mammal- 
like projections, and in the middle of the apical wall is a fifth. The sides are covered with 
golden yellow pubescence. At the base of the cones are flecks of brownish hue. The 
venter is golden yellow, covered with pubescence; the spinnerets blackish brown. The 
epigynum (Figs. la, 1b) has a brief columnar atriolum of dark brown, from which projects 
a scapus very wide at the base, from the middle of which issues a short rounded point. 
Main: Total length, 4.9 mm.; cephalothorax, 2.5 mm. long, 2 mm. wide; facial width, 
1.1 mm.; abdomen, 2.4 mm. long, 1.8 mm. wide. The male resembles the female in general 
characters and colors, but is smaller. The face lacks the dark transverse band observed 
upon the female. The abdomen differs from that of the female in having the shoulder 
tubercles single instead of bifid. The legs are all provided with short strong spines; order 
of length, 1, 2=4, 3, as follows: 7.9, 6.2, 6.2, 4.6. Tibia-II is thicker than tibia-I, and 
armed with more and stronger spines. Coxa-I has an obtuse spur at its under side, and 
the fourth coxa a smaller and sharply pointed one. 
Disrripurion: Florida, Louisiana, Alabama, and probably throughout the entire Southern 
States. According to Cambridge, this interesting and curious spider has been collected in 
Guatemala and Panama, and is probably distributed throughout Central America. (Marx 
Collection.) 
Genus WIXIA, Camprinas, 1882. 
The genus Wixia is especially differenced from Epeira: (1) By the shape of the caput, 
which is not narrowed in front, but is wide, or even a little wider than the base; (2) by 
the strong eye eminence upon which the ocular quad is placed, the léwer part of which 
towers above and overhangs the face; (3) by the excessive size of the rear eyes of the 
middle group; (4) by the fact that both eye rows are procurved, and that the separating 
distance between the side group and the middle group is greater than the proportionate 
height of the clypeus, which is eyen greater than that of the length of the ocular quad, 
which (5) also differs from that of Epeira in having the rear width greater even than the 
length; (6) in the fact that the abdomen, which is cylindrical-ovate, is carried by the 
spider in a plane almost at right angles to that of the cephalothorax. 
The male of the genus is also distinguished by the above characteristics, though in a 
modified form. The legs are especially marked by blackish denticulate spines placed 
underneath femora-II and IV, and similar spines placed upon both their trochanter and 
coxee, also upon coxee-II, Corneous spurs mark the articulation of coxee-I.
