Body eloneate : fore wings (especially in the males) elongate-triangular, pointed at the tip, broader in the females, 



paler coloured beneath than above, and much varied with interrupted transverse lines. 

 Head small, broadest in the males, finely hairy. 

 Eyes prominent, lateral, naked. 



Labial Palpi very small (especially in the females), compressed, obliquely ascending, the tip being about level 

 with the middle of the eye, but not extending beyond the hairs of the face ; terminal joint very small, nearly 



naked, and pointed. . t . v •. i 



Antenna; about three fifths of the length of the fore wings, slender ; joints almost indistinct, slightly annulated 

 with white ; club gradually formed, elongated, moderately robust, pointed at the tip. 

 Thorax moderately robust, finely hairy. , /-, i • i 



Fore Wings large, elongate-triangular ; apex more or less acute, especially in the males. Costal margin nearly 

 straiaht, except at the tip. Apical margin entire, slightly convex (rather emarginate towards the tip in those 

 males, which have the tip more acute). Inner margin nearly equal in length to the apical. Costal vein 

 reaching rather beyond the middle of the margin. Postcostal with only three branches ; the first and second 

 arising before the anterior extremity of the discoidal cell (the second one more or less nearly approaching it), 

 and the third branch arising at a considerable distance beyond the cell, and uniting with the costa at about 

 eight ninths of the length of the wing ; the terminal part of the postcostal vein itself reaching to the tip of the 

 wfng. Upper disco-cellular vein extremely short, or obsolete ; when present it arises at about the middle of 

 the wing; upper discoidal arising at its lower end (or if obsolete) from the postcostal vein in the place of the 

 upper cfisco-cellular : middle and lower disco-cellular nearly equal in length, very slender, rather varying in 

 direction, the latter uniting with the third branch of the median vein at a very short distance beyond its 

 origin. 



ni7id Wings subtriangularly ovate in the male, more broadly triangular-ovate in the female. Costal margin 

 slightly convex ; outer angle rounded. Outer margin entii-e, not much rounded; anal angle rather acute. 

 Coital vein extending to about three fourths of the length of the costa. Postcostal arising much nearer the 

 body than the precostal. Upper and lower disco-cellular veins very slender, transverse ; the former arising at 

 a short distance beyond the branching of the postcostal, and the latter close beyond the origin of the third 

 branch of the median vein. 



Fore Legs of the male small, densely hairy, simple; those of the female about twice the length of those ot the 

 male, very slender, scaly. Tarsus longer than the tibia ; joints armed with small spines beneath at the tips. 



Four liind Legs large, slender, scaly, those of the males with the femora more hairy beneath, tibia? and tarsi 

 slightly spined beneath. 

 Abdomen elongate in the males, shorter and more ovate in the females. 



The small size of the labial palpi will at once distinguish the species of this genus from those of Nymphidium and Aricnns, to which 

 they are somewhat allied. Some variation exists in the form of the fore wing.s of the different species, as well as m the sexes of the 

 same species, and even, as I helieve, in individuals of the same sex; thus some si.ccimcns of E. Lucinda have tlie fore wings scarcely 

 pointed, whilst in others of a ratlicr Im-s^hv bize they arc, in both sexes, considerably more acute at the tip. Notwithstanding this 

 difference, I apprehend all these individuals belong to one species, the females of which are, I believe, identical with Cramer's V. 

 Dyndiina. The type of the genus, as constituted by Fabricius in the Si/stima Glossatorum, is tlie E. Ovidius, a pretty species, which 

 is more strikiim- In the form of its fore wings, wiiieh apinoach those of "Syminaehia, being emarginate along tlie costal margin, and by
