Discussion. Keyserling (1877) apparently recognized the resem¬ 
blance in the color pattern and anatomy of T. avara to European 
species of Trochosa. Although most American authors have main¬ 
tained avara in Lycosa, it is generally agreed that this species 
together with the closely related gosiuta, shenandoa, and parthenus 
are close taxonomically to Trochosa terricola. 
Chamberlin and Ivie (1942) placed avara in Trochosa and made it 
the type species of their new subgenus Varacosa. Roewer (1954) 
raised Varacosa to genetic status. Trochosa avara resembles terri¬ 
cola in bodily dimensions, coloration, and habitat preference, and I 
see no good reason for separating it as a genus or subgenus at this 
stage. 
Color. Females. Face pale brownish yellow, lighter along lower 
edge of clypeus. Chelicerae darker, orange to orange-brown. Eye 
nacelles black. 
Carapace brownish yellow to yellow-brown with broad, lighter 
yellowish median stripe as in Figure 3; with only faint indications of 
short, darker stripes within median light stripe; with indistinct ligh¬ 
ter yellowish submarginal stripes. 
Dorsum of abdomen brownish yellow to pale brown, mottled 
with darker gray to black spots forming an indistinct pattern as in 
Figure 3. Cardiac area more evenly colored yellow-brown or tan. 
Venter of abdomen pale yellow to cream with a few scattered darker 
spots, mostly along edges. 
Fegs yellow to pale brownish yellow without darker markings. 
Labium and endites brownish yellow, with light ivory colored 
distal ends. Sternum pale yellow. 
Color. Males. Face pale orange-brown. Chelicerae orange-brown. 
Cymbium of palpus orange-brown, distal tip yellowish. 
Carapace orange-brown with broad median yellowish stripe. 
Faint dusky dashes within median stripe. Narrow, irregular yellow¬ 
ish submarginal stripes.
