No. 2.] SPIDERS OF THE MARPTUSA GROUP. 183 



Hudala is smaller and lower than Itata. It is higher than 

 Padilla, and the level part of the thorax is not so long as in that 

 genus, wliere the thoracic part is on the same plane as the 

 cephalic throughout its length. In Padilla the cephalothorax 

 widens out more than in Sadala, and the middle eyes of the 

 first row are not so large. 



We have seven species of these genus, all from Central and 

 South America. The tj'pe, Sadala distincta P. is described in 

 N. A. Attidse, p. 53. The other species are fenestrata (Msevia 

 fenestrata) Taez., Arachnides du Perou, p. 327 ; Stolzmanii 

 (Mgevia Stolzmanii) Tacz., ibid, p. 329, and four new species.

The cephalothorax is thickest (from above below) just in 

 front of the posterior thoracic slope. This point seems to be a 

 little the highest, also, the upper surface sloping very slightly 

 forward to the first row of eyes. There is a central depression 

 behind the dorsal eyes. The cephalothorax is narrowest in 

 front and widest in the central thoracic part. The upper sur- 

 face is flattened through the cephalic and two-thirds of the 

 thoracic part. The sides round outward in the thoracic part 

 much more widely than in front. The quadrangle is a little 

 wider in front than behind and is about one-fourth wider than 

 long. In the male it occupies two-fifths of the length of the 

 cephalothorax ; in the female a trifle less. The anterior eyes 

 are close together in a straight row, the middle being nearly 

 three times as large as the lateral. The second row is close to 

 the first. The third is not so wide as the cephalothorax. The 

 clypeus is narrow. The falces, in both sexes, are short, stout
