Labium minutely densely spinulose at distal end. 



Fovea thoracica transverse or pit-like. 



Metatarsus I scopulate nearly to base; metatarsus II scopulate to 

 or a little proximad of middle; metatarsi III and IV scopulate only 

 at distal end. Scopula of tarsus III with setose line only at base; 

 that of tarsus IV divided by a narrow median line of setae over whole 

 length. Metatarsus I armed at base as well as at apex, with a spine. 

 Metatarsus II ventrally with an apical spine and proximad of middle 

 with three, 2 in a longitudinal series with 1 mesad of the more basal of 

 these; a single spine in addition on mesal side. 



In the male metatarsus I is bowed dorsad. Tibia I with two spurs 

 at distal end of which the superior one is much the shorter; the inferior 

 or ectal one curved dorsad, the tibia closing against mesal side of its 



tip- 

 Tibia of palpus of male without trace of a rastellum of spines. 

 Type Species. — Calopelma brasUiana, sp. nov. 



In some respects this genus is intermediate between Hapalopus 

 and Hemiercus as defined by Simon. It differs from both in lacking 

 a rastellum on the tibia of the male palpus, in having the fovea thora- 

 cica transverse instead of procurved, and in the different spining of 

 metatarsus I. From Hapalopus it also differs in the inequality of the 

 eyes of the anterior row, in having the spurs of tibia I in the male 

 very unequal in length, etc.

Integument of carapace excepting in front of eye-tubercle, and of 

 legs, palpi, and chelicerae very dark chestnut, almost black; that of 

 the sternum, coxae of legs beneath, and coxae of palpi, chestnut. 

 Pubescence of carapace golden brown. Pubescence of legs brown-grey, 

 two longitudinal darker stripes showing especially on tibiae above, with 

 one basally o])li([iie one on metatarsi; bristles light brick-red, of 

 moderate length, more numerous ventrally. Sternum and coxae of 

 legs beneath with pubescence almost wholly grey with longer light 

 brick-red hairs more sparsely scattered. Abdomen above velvety
