Selenocosmiinse ( = Selenocosmiese in part, Poecilotheriese in part, 

 Ischnocolese in part, and Phlogieae). 



Theraphosiufe (= Selenocosmiese in part, Poecilotheriese in part, 

 IschnocolesB in part, Chsetopelmatese, Aviculariese, Theraphosese, 

 Eurypelmateae, Homseommatese). 



The Ethiopian genera known to me may be recognized by the 

 following characters : 



a. Outer surface of the mandible furnished above 

 with a thick scopula or pad of feathery hairs ; 

 (tarsal scopulte entire ; claws not toothed ; anterior 

 tibia of male with a single curved spine-tipped 

 spur ; posterior sternal sigilla marginal). — Sub- 

 family Harpactirin^. 

 a'. Thoracic fovea very deep and nearly circular, 

 circumscribing a central tubercular prominence, 

 as in the Central American genus Sphcerobothria ; 



mandible and spinners as in Pterinoohihis Ceratogyrus, nov. 



h'. Thoracic fovea normal, transverse. 



a^. Inner surface of mandible without feathery 

 scopula ; no stridulating organ, the inner 

 surface of the maxilla between the oral fringe 

 and the suture sparsely beset with simple 

 setffi, the adjacent area on the mandible with- 

 out rows of modified bristles ; apical segment 

 of posterior spinners longer than the second... Fterinoohilus, nov. 

 h^. Inner surface of mandible with feathery 

 scopula above ; with stridulating organ, the 

 area on the maxilla mentioned above bearing 

 a tliick cluster of notes in the form of feathery 

 hairs, the adjacent area on the mandible 

 below the external scopula with at least one 

 series of modified setse ; apical segment of 

 posterior spinners shorter than the second ... Harpactira, Auss. 

 h. Outer surface of mandible not furnished with 

 scopula of plumose hairs, at most sparsely beset 

 with normal bristles. — Subfamily Therapiiosin^ \ 

 a^. Thoracic fovea forming a round or transversely 

 elongate pit. 

 a*. Protarsi and tibiis of legs armed with many 

 strong spines ; protarsal si'Opulie scanty, 

 not extending to the bass of the segment 

 on the legs nf ihe 1st and 2nd pairs ; scopula 

 of 4th tarsus divided by a complete band of 

 setas ; anterior tibia of male without spur ... 

 6*. Leg with at most a few small spines at apex 

 of tibiae and protarsi beneath ; protarsal 

 scopulse thick, extending to base of segments 

 on legs of 1st and 2nd pairs; scopula on 

 tarsus of 4th leg entire, or at most weakly 

 (Scodra) divided in the adult. 

 a^. Sternal sigilla submarginal ; ocular area 

 wide ; without spines on the tibias of legs ; 

 scopuliB broad and very thick ; legs and 

 body thickly hairy ; claws with a few 

 small teeth ; anterior tibia of male without 

 spur Scodra, Becker.
