Sapphirina IRIS. 



Antennce posticce abbreviates, digito dimidii articuli 2di longitudine. 

 Lamellae caudales tenuiter divaricates; setis tribus, duabus apicalibus

 limum valde elongatum (latitudine maxima plus quintuple* longius).

 sequentibus vix angustiore. Maris : — Corpus linear i-ellipticum, antice 

 rotundatum. Conspicilla inferiora, fronte remotiuscula. 



Posterior antennae short, finger half as long as second joint. Caudal 

 lamellae slender, divaricate, setae three in number, two apical longer 

 than half the stylet, the other external. Female: — Body slender,

The female is much more slender than the male. In the latter, the
