No. 2.] SPIDERS OF THE MARPTUSA GROUP. 95 



Epinga has not the flat look which distinguishes Marptusa, 

 the upper line of the cepalothorax being plainly curved and the 

 abdomen nearly cj'lindrical. 



We have three species of this genus, chapoda and bar- 

 barica, new, and ornata (Bavia ornata P., New Attidte from 

 Guatemala, Proc. Nat. Hist. Soc. of Wisconsin, Dec, 1885, p. 8). 

 This last species, although rather a large spider, is more slender 

 and graceful than either of the others.

 Legs, S and ? , 1423 ; those of the first pair are stoutest 

 and longest, and are longer in the male than in 

 the female, while thej' are stouter in the female 

 than in the male. 

 This is a large, heavy spider, with the abdomen cylindri- 

 cal and about as wide as the cephalothorax. It is not so slen- 

 der as Epinga ornata. The cephalothorax of the male widens 

 out behind the dorsal eyes more than that of the female. The 

 Ciuadrangle of the Qjes is one-fourth wider than long ; is wider 

 in front than behind, and occupies two-fifths of the cephalo- 

 thorax. The anterior eyes are all separated ; thej^ form a 

 slightl}'' curved row, the middle eyes being a little less than 

 twice as large as the lateral. There is a tuft of black hairs 

 above the lateral eye and another to the side and below it. The 

 second row is nearer the first than the third. The third row 

 is not so wide as the cephalothorax at that place. 



The palpus of the male has the patella and tibia nearly 

 equal, and these two joints together are about two-thirds as long 

 as the tarsus. 



The falces are heavy and are slightly inclined forward. 

 They are covered, in front, with long, coarse hairs.
