A Key to the three Species of the Genus Neanura. 



A. Ocelli two oil each side of the head. No post-antennal organs. 



1. Bod J- without dorso-hiteral protuberances JV. intermedia. 



2. Dorso-lateral protuberances present N. coral Una. 



B. Ocelli three on each side of the head. Post-antennal organs 



present JV". pudibunda. 



Oudemans * has described a single species of this genus (J^. 

 fortis) from the Oriental region, where it occurs in Java, Sumatra, 

 and Saleyer.

Head. — The epes eight in number on each side. Post- 

 antennal organs oval in form, each with seventeen tubercles 

 (%• 2). 



Antennce. — The joints related in length to one another 

 as 5 : 6 : 4 : 11 ; the third and fourth joints pai-tially fused 

 together ; a small tri-lobed apical sense-organ, and a second sense- 

 organ situated a" short distance below the apex of the antenna. 

 Invested with a few short slender hairs ; the cuticle tuberculated. 



Trunk. — Almost entii'ely glabrous, only a few odd scattered 

 haii's being present. The cuticle uniformly tuberculated (fig. 2). 



Legs. — Short and stout ; the cuticle not tuberculated. A 

 few scattered setas on the femora and basal joints, and a double 

 circlet of setae near the distal extremity of each tibia. The claws 

 similar on each pair of legs, large and stout, more than one half 

 the length of the tibia, unarmed (fig. 3). Tenent hairs absent. 



F'urcida. — Short and stout (fig. 4), not quite reaching up to 

 the apex of the abdomen ; the cuticle uniformly tuberculated. The 

 viamd)rium and denies about equal in length, and each approxi-
