scopula of the fourth protarsus to the apical third of the 

 segment, but distinguishable from all the known genera of 

 the subfamily by the size and peculiar shape of the labium, 

 which is as long as half the length of the sternum, has the 

 form of a truncated cone, being so much narrowed anteriorly 

 that its apical width is only half the basal width, the apex 

 itself being rounded and not transversely truncated (wood- 

 cut, fig. a). Moreover the third and fourth legs are much 

 stouter than the first and second.

 rusty red, shining with silky lustre, and brighter in tint on 

 the distal segments of the legs than on the femora, carapace, 

 and abdomen. 



Carapace much longer than wide, the width less than the 

 distance between the ocular tubercle and the posterior median 

 emargination ; length equal to that of patella, tibia, and half 

 the protarsus of first leg, exceeding patella, tibia, and tarsus 

 of palp, just exceeding patella and tibia of fourth leg, but 

 barely equal to protarsus and tarsus of fourth. 



Legs 4, 1, 2, 3 in length : third and fourth much more 

 robust than first and second, first a little more than twice as
