and more slender, IV coxae and trochanter snbeqnal, and

spines at the distal end of the IV tibia, no trichobothria 
at the tip of the IV metatarsus and tarsus as in the 
female; palpus, longer than the cephalothorax, femur 
more than half the length, pale, patella pale and slender, 
twice as long as wide, tibia darker, little more than half 
as long as the patella, tibial apophysis a slender dark 
dorsal spur and a broad dark lateral spur with a truncate 
tip, as figured, the palpal organ nearly as long as the 
cymbium, bulb strongly convex, pale and extending onto 
the tibia, the tube dark and very distinct, embolus a dark

Allotype (cf) Texas; Denton, 4 December 1946, (Jones) 
The allotype male and the neotype female were found 
in quite different habitats, the female out of doors, and 
the male in a house and they do not agree in all char- 
acters. The female is larger, pale, and only tinged with 
red, on the margin of the clypeus there is a fringe of 
hairs, and on the fourth metatarsus and tarsus are some 
distinct trichobothria. The male is smaller, the abdomen 
a deep red, covered with white hairs, the eyes are more 
closely grouped, the first femur has a brush of ventral 
hairs and the trichobothria on the fourth leg are lacking. 
The difference in color may be due to the habitat and the 
other differences are probably sexual. 
In 1918-19, Dalmas published an excellent revision of 
the family Prodidomidce, which by then included five 
genera, all with the same arrangement of eyes and simi- 
lar spinnerets. The genotype, Prodidomus rufus, he 
knew only from the description of the immature speci- 
mens by Banks. Dalmas suggests that the Old World
