Superfamily Avicularioidea 



Genus AVICULARIA (A-vic-u-la'ri-a) 



The group of eyes is barely one third wider than long; the 

 anterior eyes are quite small, nearly equal, and in a strongly 

 procurved line. The posterior sigilla are small and marginal. 

 The anterior tibia of the male is furnished with one spur at the 

 apex. 



Avicularia californica (A. cal-i-for'ni-ca). — The cephalo- 

 thorax is a little more than one inch in length and two thirds inch 

 in width. The cephalothorax is densely clothed with yellowish 

 gray hair, rather paler on the sides and brighter in the middle; 

 on the anterior margin there is a fringe overhanging the chelicerae 

 of long, pale gray hairs with tawny tips. The abdomen is clothed 

 above with fine dark brown hair, and many long, recurved bristles 

 of a tawny colour with pale tips; the lower side of the abdomen is 

 clothed with black hair, and with long tawny bristles. The 

 endites and the furrow of the chelicerae bear long tawny bristles. 



This is the only species of Avicularia found in our fauna. 

 It was described by Mr. Nathan Banks from several specimens 

 collected in the vicinity of San Diego, Cal. 



Genus TAPINAUCHENIUS (Ta-pin-au-chen'i-us) 



The group of eyes is at least twice as wide as long. 

 The anterior eyes are in a nearly straight line; and the anterior 

 median eyes are larger than the anterior lateral. The posterior 

 sigilla are quite large, ovate, and submarginal. The anterior 

 tibia of the male is furnished with two spurs at the apex. 



Two species have been found in the Southwest. 



Tapinauchenius cmulescens (T. cae-ru-les'cens). — This species 

 was described by Simon from an immature female which measured 

 four fifths inch in length. The cephalothorax is densely clothed 

 with very long, silky, dark blue hairs; and the abdomen, which 

 was badly rubbed in the specimen described, is silky blue pubes- 

 cent above with a few long, yellow hairs, and is black below. 



The specimen was collected at Fort Sill, Indian Territory. 



Tapinauchenius texensis (T. tex-en'sis). — This species, like 

 the preceding, was described from an immature female. The 

 specimen measured one inch in length. The cephalothorax 

 is densely clothed with yellow hairs; and the abdomen, badly
