130 PECKHAM. [Vol. 2,. 



PADILLA GEN. NOV. 



Spiders a little below medium size. Males with first legs 

 thickened and having two spines, or horns, on the falces. 



The cephalothorax is low. It is narrow just in front, but 

 broadens out widely, the widest point being considerably be- 

 hind the dorsal eyes. This dilatation is^more marked in the 

 males than in the females. The sides slant outward, more 

 widely in the thoracic than in the cephalic part. The upper 

 surface is flat except for a rounded depression a little way be- 

 hind the dorsal eyes. The posterior slope is short. The quad- 

 rangle of the eyes is one-third wider than long, is about equally 

 wide in front and behind, and occupies barely two-fifths of the 

 cephalothorax. The first row is straight, the eyes being close 

 together and the middle fully twice as large as the lateral. The 

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

 not so wide as the cephalothorax at that place. 



We have two species of Padilla, armata and cornuta, both 

 from Madagascar. The males of both these species have long 

 spines, or horns, projecting from the falces. We have described 

 cornuta as Icius cornutus, Proc. Nat. Hist. Soc. of Wisconsin, 

 March, 1885, p. 30. 



The genera that most nearly resemble Padilla, Anoka 

 and Sadala, are found only in the Western Hemisphere. The 

 only genus in Madagascar that it could be confused with is 

 Spadera. Padilla, however, has the cephalic part flat, the quad- 

 rangle of the eyes one-third wider than long, and the middle 

 eyes of the first row fully twice as large as the lateral ; while in 

 Spadera the cephalic part is inclined forward, the quadrangle 

 of the eyes is only about one-fifth wider than long, and the 

 middle eyes of the first row are less than twice as large as the 

 lateral. Moreover, the males of Padilla have horns on the 

 falces, which are lacking in Spadera.
