Oxyplila monroensis Kejserling. — Cepha- 

 lothorax dark brown on sides, paler in 

 middle especially behind; anterior legs dark 

 brown, femora darker than other joints; 

 posterior legs with a dark band at tips of 

 femora and one at base of tibiae ; coxae and 

 sternum brownish, abdomen dark brown 

 witli a number of small pale dots arranged 

 somewhat in rows. Tlie epigynum consists 

 of a broad cavity somewhat like conspurcata, 

 but the posterior ridge is only slightly 

 concave, and each end limited by a dark 

 oval body; the rounded lobe in front seems 

 to have a cavity at tip; the two small pos- 

 terior holes are quite close to each other. 

 The legs are shorter tlian in O. conspnycata.

Oxyptila conspurcata Thorell. (O. gcor- 

 giana Keyserling.) — Cephalothorax reddish 

 yellow, paler in middle, usually with some 

 silvery white lines, white around eyes; the 

 sides often nearlv wholly uniform brown, or 

 two brown stripes, the upper one broadest 

 behind and ending in a darker spot, legs 

 pale yellowish or reddish brown, not mottled, 

 the posterior pair with a black band at tip of 

 femur, a black spot on patella, and a basal 

 black band on tibia; sternum yellowish or 

 brownish; abdomen yellowish, anterior sides 

 brown, two spots on anterior margin, often 

 with silvery spots, and many black ones 

 which behind form three irregular dark 

 bands. The epigynum consists of a broad 



cavity limited behind by a deeply emarginate 

 line or ridge, whicii is most prominent on 

 the sides, in front a rounded lobe projects 

 caudad. from each of the small holes there 

 projects an oblique dark body or cavit\', the 

 surface above is striate. This gives the 

 appearance figured by Keyserling.

 recorded ^eor^/a«a from Georgia and 

 froin Peoria, 111. Most of the northern 

 specimens have the four stripes on 

 cephalothorax ; but in a large series 

 from Poughkeepsie both forms occur 

 and numerous gradations ; those with 

 four stripes usually have very pale legs.
