unlike any other species. The epigynum is not unlike Lycosa 
fatifera (Hentz) but that species has no thoracic or abdom- 
inal markings and the venter is light. The black first tarsus 
and metatarsus are very conspicuous. 
Schizocosa duplex Chamberlin (PI. V, Fig. 11.) 
Bull. Mus. Comp. Zook, 1925, 67, p. 231. 
$ 6.5 mm. 
Cephalothorax with a median stripe of yellow, narrower 
than the third eye row and extending between the eyes of 
that row, margins even and slightly converging, sides dark 
brown with many white hairs, a narrow light supramarginal 
stripe rather broken ; eyes, anterior row shorter than second 
row, a.m.e. separated by nearly a diameter and from a. he. by 
a radius, eyes of second row separated by a diameter and a 
half ; quadrangle of posterior eyes wider behind than high ; 
mandibles dark with three teeth on inferior margin of fang 
groove; sternum dark with a light stripe in middle; coxse 
light ; abdomen with a converging median light stripe from 
base to spinnerets, usual basal spear mark within rather in- 
distinct and posterior half of median stripe with indistinct 
cross bars, sides dark ; venter light with a row of dark spots 
about sides meeting at the spinnerets ; legs brown with very 
faint darker rings on femora, anterior patellae and tibiae 
darker; epigynum, the median septum very long and nar- 
row, sides parallel, cross piece shorter than median septum 
and the upper section narrower than the lower, the division 
on each side about one third the length of the cross piece. 
Allotype $ Florida; Sebastian, 1922 (G. Nelson). 
The male was described from Fairfax, Virginia, in 1925. 
It differs from Schizocosa ocreata (Hentz) by the lack of a 
brush of black hairs on the first tibia and the shorter horn 
in the male palpus. The females differ from S. ocreata by 
the very long and narrow septum in the epigynum and the 
comparatively short division in the cross pieces. Specimens 
collected by Mr. H. K. Wallace from Alachua Co., Florida, 
have the median stripe on the abdomen very distinct and the 
basal spear mark and cross bars very faint, so that the ab- 
dominal stripe appears as a continuation of the median 
stripe on the cephalothorax. Hentz describes and figures
