Key to the genera of the subfamily Cryptinz. 
1. Antenne distinctly shorter than body, somewhat thickened toward apex; 
areolet defined, though often open; nervellus broken below middle; 
propodeum without any trace of apical carina, spiracles very small, 
nearly round : Nematopodius Gravenhorst. 
Antenne nearly or quite as long as body, very slender, filiform or 
attenuate toward apex; areolet not defined; nervellus broken above 
middle; apical carina developed at sides; spiracles large, long oval.... 2. 
2. Malar space and clypeus very short, latter extending far laterally below 
eyes; epomia ending above in a sharp tooth; thorax and propodeum 
polished, impunctate; prescutum gibbous.................. Earrana Cameron. 
Malar space and clypeus not especially short, latter not especially 
produced laterally; epomia becoming obsolete above; thorax and pro- 
podeum very coarsely punctate; prescutum very low anteriorly.

I think there can be no doubt of the synonymy of Morley’s 
genus. His type is from the identical locality with Cameron’s, 
and so far as the two generic descriptions treat of the same 
structures they coincide very closely. There also seems to pe 
very little if any reason to doubt the synonymy of the two geno- 
types. In Morley’s placing of the genus it is without doubt 
“s remarkably distinct genus” and “by no means a typical 
Paniscid.” 
The following generic description includes characters not 
mentioned by either Cameron or Morley and introduces the 
hitherto unknown male: Entire body polished, practically with- 
out sculpture; head distinctly wider than thorax, transverse, 
with temples convexly sloping; eyes large, prominent, their inner 
margins entire, convergent below; clypeus distinctly separated, 
very broad and extending laterally far under eyes, fover 
touching eyes; mandibles very narrow at apex, the lower tooth 
obsolete to absent; occiput rather deeply concave, the carina 
lacking medially ; antenne nearly as long as body, very slender, 
filiform; maxillary palpi long, all joints slender, slightly deeper 
than high; pronotum with a strong curved carina along its 
anterolateral margin, epomia strong, straight, ending above in 
a sharp tubercle; propleura longitudinally carinate outwardly; 
notauli deep and complete, meeting before the scutellum, prescu- 
tum and lateral lobes strongly convex; scutellum nearly convex, 
margined at base; sternauli nearly complete, weakly double-
