EUTKESIS. in 



Genus VI. EUTRESIS. 



Head rather broad. 



Eyes oval, not remarkably prominent. 



Maxillae extending beyond the middle of the thorax. 



Labial Palpi rather slender, scarcely rising above the forehead ; all the joints scaly and hairy. 

 First joint subcylindric, curved ; second joint about one third longer than the first, subcylindric, 

 smaller towards the apex, the dorsal tuft not very large ; third joint much slenderer, tapering, 

 about one third of the length of the second. 



Antenna fully three fourths as long as the body, insensibly enlarged into an elongate club; the 

 terminal joints more distinctly separated ; the last obtusely pointed. 

 Thorax short, moderately stout. 



Anterior Wings opaque, with slightly diaphanous markings, elongate, subtriangular ; the anterior 

 margin slightly curved ; outer margin rounded, fully three fifths the length of the anterior ; 

 inner margin slightly emarginate, equal in length to the outer. Costal nervure extending 

 beyond the middle of the wing. Subcostal nervure emitting its first nervule about the middle 

 of its course, considerably before the end of the cell ; the second about at an equal distance 

 beyond the cell ; the third at a less distance from the second than the space between the latter 

 and end of the cell; the fourth not so near to the second as this to the third. Upper 

 disco-cellular nervule very short. Middle disco-cellular directed inwards for three fourths of 

 its length, then suddenly bent outwards, the angle presenting a short trace of the discoidal 

 nervure. Lower disco-cellular not quite so long as the upper, slightly sinuous, directed 

 obliquely outwards, reaching the third median nervule, where the latter makes a considerable 

 angle. Internal nervule short, running into the submedian. 



Posterior Whigs opaque, almost obovate ; the anterior margin slightly produced into a shoulder at 

 the base ; the cell scarcely one half the length of the wing. Precostal nervure simple. Costal 

 nervure attaining the costa beyond the middle. Upper disco-cellular nervule arising from the 

 second subcostal close to its origin, directed obliquely inwards. Lower disco-cellular arising 

 from the discoidal nervure a little before the point where this nervure is joined by the upper 

 disco-cellular, directed immediately downwards to the third submedian nervule which is bent at 

 an obtuse angle at the point of contact. Discoidal nervure extending considerably into 

 the cell. 



Anterior Legs of the male with the femur and tibia nearly equal, the latter slightly longer than 

 the former, subcylindric, both clothed with scales and a few long scattered hairs. Tarsus
