DESCRIPTION OF GENERA AND SPECIES. 181 
distinct, covered slightly with gray hairs; a uniform brown; labium triangular; maxillee 
as wide or wider than long, subtriangular at the tips; both colored as the sternum, but a 
rather lighter hue. 
Eyrs: Ocular quad on a rather squarish rounded eminence, of which the front is 
more pronounced; MF upon separate tubercles, black, about the size of MR, which are 
bright amber color; the quad barely longer than wide, slightly wider in front than behind; 
MF separated by about 1.75 diameter; MR by about 1.5; side eyes upon slight tubercles, 
about equal in size, contingent; SR well to the side and separated from MR by 1.3 the 
area of the latter. MI separated from SF by little more than their area, or 1.3 their 
interval; the height of the clypeus equal to about 1.5 diameter MF; front row but little 
recurved, rear row longer, and from the same aspect procurved, but viewed from above 
but a little, is aligned. 
Lees: 1, 2, 4,3; yellow, with darker annuli at the tips, and slight annuli at the 
middle of the metatarsus and tibia; freely provided with grayish yellow hairs, bristles, 
and dark long spines; the palps are eolored and armed as the legs; mandibles subcylin- 
drical, long, strong, brownish yellow, pubescent. 
AppomEn: Subtriangular, thickened at the base, which rises almost perpendicularly 
from the corselet, forming an angle with the dorsal field; the latter arched to the apex, 
which slightly overhangs the spinnerets. The abdomen is thus divided into two sub- 
triangular fields; the front is mottled cretaceous and blackish, punctuated with numerous 
black spots; reticulated, with a lanceolated cretaceous band between the shoulder humps; 
the dorsal field is cretaceous or yellow, which color extends along the inside and posterior 
of the rounded, strongly marked shoulder humps; between the humps, in one specimen, are 
two oblong bright white patches, which take the place of the cretaceous extension above 
referred to. The dorsal field is marked by a decided folium, which occupies half thereof; 
it is outlined by a cretaceous undulating margin, within which extends a parallel line of 
black to the apex; beyond this are yellowish shades extending to the median pattern, 
which is an interrupted cretaceous or yellow ribbon. The venter is a brownish yellow 
ribbon, compressed in the middle, with wide semicircular patches of reticulated white and 
yellow on each side, which merge into similarly colored stripes along the sides of the abdo- 
men. The epigynum has a long, yellowish white, conyoluted scapus (Fig. 15a), whose stalk 
is of about equal width throughout, and terminates in a widened and rounded spoon. The 
atriolum rises from the margin of the genital cleft as a hollow bowl or shell, from the base 
of which the scapus originates. 
Mae: Fig. 16. Resembles in general form and markings the female. The cephalo- 
thorax is more oval, the head relatively narrower at the face, the legs have wider and 
darker annuli at the tips; the abdomen is relatively narrower at the base than the female, 
though with the same general conformation, and with smaller shoulder humps; the folium 
is outlined at the margin by an interrupted waving band of black, margined by white. A 
brownish yellow median line shoots between the shoulder humps, sending forth four longi- 
tudinal branches of like color along the middle of the folium to the apex. Tibia-II is not 
thickened, and has no distinctive clasping spines; is simply provided with three rows of 
long brownish spines. Tibia-I is greatly longer than tibia-II, and has more spines thereon. 
Femora-I and II are covered, except near the bases, with wide dark brown annuli; the 
palpal digit is globular, glossy, and brown; the cymbium blackish, covered well with 
grayish hairs. 
Distrrurion: I have three females and one male of this species, received from Cali- 
fornia; and two other females and an immature male from San Diego, Cal. 
Tue LArcerR ANGULATA,. 
The smaller Angulata above described might, perhaps, be properly assigned to a sub- 
genus, Its principal characteristics, apart from the small size of its species, would be a 
high and subconical corselet; an epigynum with a scapus much convoluted or wrinkled, ter- 
minating in a ladlelike tip; an abdomen of marked triangular form; a diminished interval
