DESCRIPTION OF GENERA AND SPECIES. 157 
ence, Should this resemblance prove to be identity, the distribution of the species would 
be extended, in the United States, to the Rio Grande of Texas, and also into Arizona, 
and its habitat become the semitropical and tropical parts of North America, including the 
West Indies; probably also the northernmost South American States.

Fremare: Total length, 14 mm.; abdomen, 10.4 mm. long and 7 mm. wide; cephalo- 
thorax, 5 mm. long by 4 mm. wide; width at the face, 1.8 mm. 
CrpHaLoTHorax: A rounded oval; fosse deep; cephalic suture distinct; head but lit- 
tle depressed at the base, rounding to the face; corselet brown, with yellow marginal stripe 
covered with rather long grayish white hairs, bristlelike at base and along sides of the 
caput. Head yellow, well covered with long, stiff gray hairs. Sternum shield shape, brown, 
heavily covered with long, gray bristlelike hairs; labium rather narrow, subtriangular, less 
than half the height of maxillz, which are apparently somewhat wider than long, rounded, 
and yellow like the labium and surrounding cox. 
= Leas: 1, 2, 4, 3, as follows: 18, 16.2, 15.4, 10.7 mm.; stout, strongly annulated, with 
dark brown rings at tips and middle of tibia and metatarsus; a brown hue diffused over 
upper surface of femora; strongly armored with long gray hairs, bristles, and numerous 
long black spines; palps colored and armed as legs; mandibles strong, curved at bases, yel- 
low tipped with brown; slightly pubescent. 
Eyes: Ocular quad on a high rounded eminence, which is almost a square, but wider 
in front than behind; MR oval and decidedly larger than ME; the latter separated by 
about 1.5 to 2 diameters; MR about one diameter. Side eyes on tubercles, scarcely contin- 
gent; SR larger than SF, which are separated from MF by at least two and a half times 
the space that divides the latter. Clypeus high, its margin removed from MF by three 
and a half to four times a diameter of the latter, or considerably more than intervening 
space between MF and SF; front row recurved, rear row somewhat procurved. The face 
around the central eminence is thickly covered with stiff gray bristles which project over 
the margin. 
Aspommn: A long oval, the dorsal field yellow interspersed with brown; the folium is 
outlined by thicker semicircular patches of grayish white bristlelike hairs, which heavily 
cover the entire organ. In the centre is a white herring bone marking with at least five 
angular projections and indentations symmetrically arranged on either side. This herring 
bone pattern is chiefly emphasized by the gray: hairs, the field beneath being yellow mar- 
gined with brown. From the middle of the folium downward are arranged symmetrically 
on either side rows of three circular spots, like buttons. The folium diminishes towards 
the apex ; sides yellow, intermingled, with brown amidst gray hairs; spinnerets at the foot 
of the apical wall which very slightly overhangs them; color brown, with lighter hue at 
the bases. The yenter is covered with gray hairs over a brownish field, with yellow spots 
on either side heavily covered with gray hairs. The epigynum (Fig. 1b, 1c) is long and 
triangular, wide at the base and diminishing sharply to a point, upon which is a rounded 
dot. It is hollowed upon the lower anterior surface and is covered with rows of stiff 
white hairs. 
Mate (Fig. 2): In color and marking closely resembles the female; length (two speci- 
mens), 9 mm., 8 mm. Cephalothorax a longer oval than the female. The legs differ in 
lacking the decided brown annuli of the female; are heavily armed with spines and
