trochanter of the palp. Coxa of first leg clotlied anteriorly 

 with long hairs, many (? all) of which have thickened spini- 

 form bases. 



Type B. (Emilia (White). 



Also contains Brachypelma vagans (Auss.), B. albiceps, 

 nov.* ( ? nee c?), B. Smithii (F. Cambr.), and others from 

 Mexico. 



Distribution. Central America. 



Genus SPHiEROBOTHEiA, Karsch. 



In Sphcerobothria (male) the femur, trochanter, and adja- 

 cent area of the coxa of the first leg and the corresponding 

 areas on the posterior side of the coxa and trochanter of the 

 palp are scopulate. 



In the female the scopulate hairs on the first leg are much 

 less richly developed. 



Type (and only known species) S. Hqfmanni, Karsch.

Genus Paraphysa, Simon. 

 Paraphysa, Simon, Hist. Nat. Araign. i. p. 166 (1892). 

 Specimens that I refer to Paraphysa manicata — a species 

 which is abundant in Chili — have the anterior side of the 

 coxa, trochanter, and base of femur of first leg uniformly 

 clothed with long bristles, similar in form and subequal in 

 length. Similar bristles are present upon the posterior side 

 of the trochanter of the palp. The character of the genus 

 taken from the small number of labial cusps has little syste- 

 matic value, the number of cusps varying from seven to over 

 thirty. 



Type P. manicata^ Sim. 



Genus Phryxotrichus, Simon. 

 Thnjxotrichus, Simon, Hist. Nat. Araign. i. p. 163 (1892). 



In P, auratus, the only species known to me which 

 appears to fall certainly into tiiis genus as diagnosed by 

 Sirnon, the palp and first leg are clothed with hairs, somewhat 

 similar in form and situation to those of Paraphysa ; but the 

 bristles on the coxa and trochanter of the first leg are more 

 aciculate.
