almost equally wide in front and behind, and occupies two- 

 fifths of the length of the cephalothorax. The anterior eyes 

 are small, in a straight row ; they are close together. The 

 middle are less than twice as large as the lateral eyes. The 

 second row is half-way between the first and the third. The 

 third row is nearly as wide as the cephalothorax in that place. 

 The lip is longer than wide. 



This genus is nearest Hyctia, but the body is not so long 

 and slender as in that genus, the first legs are not so long and 

 stout, the middle eyes of the first row are not nearly twice as 

 large as the lateral, and the cephalothorax is not so flat nor are its 

 sides quite parallel. Hyctia is more like Itata than like Spadera. 

 The only similar genus in Madagascar is Padilla, which is 

 marked off from Spadera by the position of the eyes and the 

 shape of the cephalothorax.

S . Length, 4.8. Length of cephalothorax, 2 ; width of 



cephalothorax, 1.2. 

 Legs, 1432 ; first pair plainly stoutest. 



The falces are short but stout and project obliquely forward. 

 The fang is rather long. The maxillte are rounded and are more 

 than twice as long as the labium. The sternum is twice as long^ 

 as wide. The femur, patella and tibia of the first leg are thick- 

 ened, especially the femur. 



The color of the cephalothorax is dark brown; the eye 

 region is blackish. The upper surface is thinly covered with 

 mixed red and white hairs. A wide, white band encircles the 

 lower sides and below this is a black line. The clypeus and 

 palpus are covered with white hairs. The abdomen is light 

 brown, with a dark region down the middle, which consists of 

 two triangular figures on the anterior and middle part and 

 some rounded spots behind. There is a transverse, curved, 

 white band at the anterior end of the abdomen, and another 

 across the middle ; and the brown spots at the posterior end are
