nice and labium lighter. Legs yellowish-brown, without darker 

 markings or with them ou the femora only. 



Color in Alcohol, S'd- — Cephalothorax reddish-brown, the 

 extreme margin black, a broad reddish median band of the same 

 shape as in the ? , and in the region of the median groove radia- 

 tions of the same color from it to a broad submarginal band com- 

 posed of whitish hairs. Sternum reddish-brown, with darker 

 margin and black hairs. Abdomen above brown, a black stripe on 

 either margin extending from the anterior end to behind the 

 middle, and behind each of these stripes one or two dark spots; 

 sides brownish ; venter darker brown, lighter antei-ior to the lung 

 slits. Chelicera black. Labium black at base only. Maxillce 

 clear reddish-browu, like the coxxe. Legs reddish-brown. Palpi 

 colored like the legs, the tarsus darker. 



Comparisons. — This species is very similar to Lycosa Jcochii Keys, 

 in general coloration, dimensions and form. 1 have decided to 

 separate them on the ground of the differences in the form of the 

 epigynum. Keyserling's figure shows the epigynum rounded ante- 

 riorly, the swollen portion of the median piece very large, and this 

 median portion with a deep groove on each side of it. In all the 

 specimens of purcelli, on the other hand, the epigynum is conically 

 pointed anteriorly, the swollen portion of the median piece is less 

 than half the length of this piece, there is not a deep groove all 

 around the median piece, and the marginal pieces are quite different 

 in form from those represented in Keyserling's figure. Eraerton 

 has figured only a portion of the epigynum, so that I cannot decide 

 whether he desci'ibed kochii or purcelli ; and Banks has not given 

 any description, 



l^In general coloration this species is very similar to L. Jrondicola 

 Emerton, and some males of purcelli are as dark on the venter as 

 the males of Jrondicola. The epigyna and d^ palpi offer good 

 diagnostic differences, and the cephalothorax is more slender in 

 Jrondicola. 



I dedicate this species to my old friend, Dr. W. F. Purcell, of 

 the South African Museum, Capetown, who has written much of 

 importance on the morphology and classification of different groups 

 of the Arachnida.
