252 THE GENUS TAPINOCYBA. 



SO that the distance between the anterior and posterior centrals 

 is less than one diameter of the latter. Epigyne small, incon- 

 spicuous, not deeply pigmented. 



I. Posterior row of eyes roughly equidistant : 



T. siibitanea (Camb.), (see figure of vulva). 

 II. Central posteriors nearer to the adjacent laterals 

 than to each other : T. praecox (Camb.), 



(see figure of vulva). 



B. — Eyes of medium size, central anteriors much less than 

 central posteriors. The trapezium formed by the four centrals 

 is much narrower in front than behind, and much longer than 

 broad. The posterior row is strongly procurved, and the 

 distance between the anterior and posterior centrals is a good 

 deal wider than one diameter of either of them. Epigyne 

 large, conspicuous, and deeply pigmented. 



1. T, mitis (Camb.). See figure of vulva. 



2. T. pallens (Camb.). See figure of vulva. 



3. T. i7isectus (L. K.). See figure of vulva. 



Males. 



A. — Palpal tibia bearing an apophysis which terminates in 

 a fine point. Palpal tarsus narrow. Palpal organs small and 

 inconspicuous. 



I. Apophysis very minute and thornlike. Patella of 



palpus longer than tibia : T. praecox (Camb.) 



II. Apophysis about as long as tibia. Patella of 



palpus shorter than tibia : T. subitanea (Camb.) 



B. — Palpal tibia bearing a bifid apophysis. Tarsus of 

 palpus broad. Palpal organs large, well developed, and con- 

 spicuous. 



I. The processes of the apophysis about equal in length. 

 {a) Processes large, stout, and blunt : 



T. pallens (Camb.) 

 (^) Processes very minute, the inner one thorn- 

 like, the outer one blunter: T. viitis (Camb.) 

 II. The internal process much longer than the outer 



one, and rather curved : T. Insectus (L. K.)
