DESCRIPTION OF GENERA AND SPECIES, © 167 
FrmaLe: Two specimens, total length, 8.5 (14.2) mm.; abdomen, 5 (10) mm. long, 2.5 
(6.9) mm. wide; cephalothorax, 3.5 (5.5) mm. long, 2.5 (4.2) mm. wide. General colors on the 
fore part a yellowish brown; abdomen, yellow. (Fig. 8.) The species is notable for the wide 
difference in size of its individuals, as may be seen by the two measurements given above. 
CrpHALoTHORAX: Corselet rounded at margin, high in centre, fosse long and deep; 
cephalic suture well marked; corselet grooves indistinct; caput somewhat raised from the 
corselet, but slightly depressed at the face, which is squarish and wide; color uniform 
yellow, with a dark median longitudinal ribbon from the face along the caput. Sternum 
slightly longer than wide, with feeble sternal cones; yellow, and lighter cretaceous inter- 
rupted median band; lip triangular, about half the length of maxille, which are somewhat 
longer than wide, and subtriangular at tips, which are directed towards one another; color 
yellowish brown. 
Eyes: Ocular quad somewhat longer than wide, and of about equal width in front and 
behind. MF upon slight projecting tubercles, separated by about 1 to 1.3 diameter; about 
equal in size to MR, which are separated by about the same distance. Side eyes on 
tubercles, with a cluster of wide bristles behind them as eyebrows; SF somewhat larger 
than SR, barely separated; SF removed from MF about 1.3 their area, or about 2.5 the 
dividing interval of MF; clypeus low, less than one diameter MF in height. Front row 
recurved; rear row longer and procurved. 
Leas: 1, 4, 2, 3, as follows: 211, 19.7, 18.5, 12 mm. Uniform yellow color, abundantly 
armed with bristles and hairs, and well provided with spines of dark brown color; palps 
armed and colored as legs; mandibles long, conical, and not divergent; color of legs. 
Aspomen: A long oval; the dorsum arched, and somewhat narrower at apex than 
base; nearly twice as long as wide; color of field yellow, with a broad median longitudinal 
eretaceous band, which is narrowed at the apex, having a ragged marginal border of black, 
and a median lanceolated band of yellow. Venter with a median yellow band, with yellow 
cretaceous border; epigynum (Fig. 8a) has a rather narrow atriolum, out of which rises a 
stout scapus wide at the base, somewhat constricted at the middle, terminating in a long 
spoon, widest at the base and rounded at tip, which is dark brown, glossy, chitinous. 
Mate: Fig. 9, 9a. In color and markings generally resembles the female, but lighter 
on the abdomen; the corselet differs in its decidedly rounded character, which, however; 
does not appear upon the sternum; corselet uniform glossy yellowish brown, and some- 
what-elevated ; cephalic suture less distinct than in female; clypeus a little higher than in 
female, and ocular quad more eyidently slightly narrowed behind; SF not relatively so 
widely separated from MF. Legs yellow and darker at joint; tibia-II curved, thickened, 
with a double row of black clasping spines extending the entire length of the joints on the 
inside, longer and stouter at the base, and flanked by several ordinary black spines. 
There is also a double row of spines underneath femur-IJ, and a small but feebler arma- 
ture underneath femur-I; spines are abundant upon all joints, of a dark or blackish brown 
color. Coxa-I has next the trochanter a long, strong, brownish spur, curved at the point; 
coxa-IV has a conical spur nearer the middle of the joint. 
Disrripurion: Male and female, San Diego, Cal. (Marx Collection.) There is prob- 
ably no American spider with wider exotic distribution than this species. It is reported 
from New Guinea, where Walckenaer first described it; Cape York, Singapore, Amboia, 
and is found in New Holland. It is thus dispersed throughout the Australian archipelago 
and the islands of Malasia. It may have secured its lodgment in California by importation 
from these quarters, but will probably be found in Central and South America.

FemaLe: Total length, 5.5 mm.; abdomen, 4 mm. long, 3 mm. wide. Specimens 
obtained from Florida through Dr. George Marx retain their color well in alcohol, the 
fore part being a light yellow, the abdomen green, with bright yellow spots.
