the retinaculum absent ; the apex produced and acute, the termen very obUque 

 and somewhat excised below apex ; veins 3 and 5 from angle of cell, 4 absent ; 

 the discocellulars erect ; 6 absent ; 7 from upper angle, closely approximated 

 to but not anastomosing -with 8. 



The genus has a remarkable superficial resemblance to AgdisUs. 



Agdistopis petrochroa ii. sp. 



Head, thorax and abdomen ochreous white with a brownish tinge, the
