Our ATYPID/E and THERAPHOSID/E. 



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 lun^- 

 . 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. 



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



Of Atypidae we have but one genus, Atypus; 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. rujipes 

 found by Mr. Milbert." A. bicolor Lucas is black, with red Ic^s; 

 only known from "Philadelphia." A. niger Hentz 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. 



Eriodontiuee. 

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