Our ATYPID/E and THERAPHOSIOyE. 



By Nathan Banks, Washington, D. C. 



These two families of spiders contain what are commonly called 

 tarantulas, the Mygalidae of older authors. They have four lung- 

 sacs, the fang of the mandibles moves vertically, the legs are 

 short and stout. The two families may be tabulated thus: 



Maxillae broadened at base, palpi lateral Atypidae. 



INIaxillse not broadened at base, palpi terminal, or almost so. Theraphosidae. 



Of Atypidae we have but one genus, Atypics; two species of 

 which have been described from the Western States. A. bicolor 

 Lucas may, if any one is fortunate enough to obtain a specimen, 

 form another genus on account of the arrangement of the eyes. 

 It is probably the species to which Hentz refers as the ' 'A. rufipes 

 found by Mr. Milbert. " A. bicolor Lucas is black, with red legs; 

 only known from "Philadelphia." A. niger VL^xAz is wholly 

 black; from Mass., Md., D. C, Va., N. C. 



The Theraphosidae may be divided into two subfamilies: 

 Inner distal angle of maxillae slightly prolonged, palpi somewhat lateral. 



Eriodontinae. 

 Inner distal angle of maxillae not prolonged, palpi terminal. Theraphosinae'
