 Sjjlhet. By Edward Doubleday, Esq. 



Family. — Noctuid^ . 



Genus. — Iontha, Doubleday. 



Maxillae rather long. Palpi triarliculate, basal joint very short, 

 second long, robust, ascending, densely clothed with long scales, 

 third long, slender, clothed with minute apprest scales. Antennae 

 serrate, (probably very long). Eyes large. Anterior wings elongate, 

 trigonate, costal nenau'e reaching to about one-third of the length of 

 the costa, subcostal nervure emitting 

 a branch to the costa not far from the 

 base, forming a small elongate areo- 

 let, from which four nervules are 

 thrown off, two at its termination, 

 one from its upper and one from its 

 under side, shortly before its termi- 

 nation : of these four nervules the 

 two upper attain the costal, the two 

 lower the outer margin : median ner- 

 vure emitting a branch not far from 

 the base, which attains the outer an- 

 gle, itself attaining the outer margin a little above that angle : about 

 the middle of its course it throws off an ascending branch, which is 

 bent soon after at its origin, and at the median fold meets a descend- 

 ing branch of the subcostal, with which it forms an obtuse angle, and 

 thus closes the discoidal cell : radial nervure none. Posterior wings 

 long, broad, nearly triangular, slightly produced near the anal angle. 

 Legs ; first pair moderate, femora and tibiae densely clothed, tarsi 

 long, claws minute ; second pair elongate, tibiae about equal in length 

 to the femora, unarmed, tarsi much longer than the tibias, basal joint 

 longer than the others combined ; posterior femora short and slender, 

 tibiae slender, (part of tibiee and tarsi wanting). Abdomen very elon-
