chamberlin: the arachnida. 257 



Carapace yellowish or pale testaceous. Eyes black. Sternum 

 yellow. Legs clear yellow, wholly unmarked. Abdomen beneath 

 pale yellowish or whitish yellow, unmarked, but the spinnerets ab- 

 ruptly darker and together appearing like a black spot at the tip of 

 the abdomen; lower part of sides with fine dark dots and streaks; 

 dorsum above dark grey, the color mesally solid and laterally in a 

 fine network enclosing light spots, along the middle line with a series 

 of whitish spots extending over whole length, the most conspicuous 

 marks being three pairs of widely separated black dots and in addition 

 toward caudal end a quadrangle of four more closely approximate 

 black spots. 



Posterior row of eyes strongly recurved; medians four fifths their 

 diameter apart and three and three fifths their diameter from the 

 laterals. Lateral eyes contiguous, nearly equal. Anterior row of 

 eyes a little recurved; medians their diameter or a little more apart, 

 not quite fully three times their diameter from the laterals. Area of 

 median eyes a little wider in front than behind (13: 121), very slightly 

 wider than long. 



Sternum longer than wide in the ratio 11:9, caudad narrowly 

 triangular, the caudal tip not sharply defined. 



Labium and endites of typical general form. 



Legs of male conspicuously spined as usual, the spines of tibiae, 

 especially of tibia I, longer, stouter and more numerous than those of 

 femora and patellae as usual, the metatarsi and tarsi with but few 

 spines. Legs in the female more weakly aculeate as usual. 



Process of cymbium in palpus of male on ectal side of base, arising 

 from a broad base, curved, ending in a swollen tip or button. Patella 

 with a single long spine at distal end above. 



Length 5-6 mm. 



Localities. — Below Lucma. (Type, M. C. Z. 238; paratypes, 

 M. C. Z. 239, one adult male, one immature male, and three immature 

 females). Tincochaca, 7,000 feet, August. (M. C. Z. 240, one male). 



Anawixia,^ gen. nov. 



Thoracic furrow deep, longitudinal, continued upon head, not 

 separated from cervical depression. 



Area of median eyes much wider in front than behind. Posterior 

 median eyes decidedly smaller than the anterior, separated by a 

 distance somewhat greater than their diameter. Anterior median
