PLATE: V. 
DESCRIPTIONS OF TWO PAPILIONIFORM MOTHS FROM ASSAM. 
Inrenvine to illustrate in this work such species of the beautiful 
genus Papilio (as restricted by modern authors), as have not 
hitherto been described and figured (of which a considerable number 
exist in English cabinets), I selected from the collection of R. H. 
Solly, Esq., formed in Assam by Mr. Griffith, the two insects in the 
accompanying plate, which, although peculiar in the form of the 
hind wings, I considered to be new species of that genus. The size 
of the insects, their general form, and, above all, the distribution 
of their colours, gave to them so great a similarity to various species 
of Papilio, that it was not until I examined the arrangement of the 
veins of the wings, and the structure of the feet, that I perceived 
that the two insects were, in fact, not only not Papiliones, but even 
not Diurnal Lepidoptera. The antennze, unfortunately, are wanting 
in both the specimens, but the characters noticed above at once 
prove them to be moths, which have assumed, or to speak more 
correctly, which exhibit, the general appearance of species of the 
restricted genus Papilio. These circumstances, united with the 
impossibility of arranging these insects in any of the already cha- 
racterised genera with which I am acquainted, render necessary the 
establishment of a new genus, which may be named, in allusion to 
the extraordinary incision at the outer angle of the hind wings, 
EPICOPEIA W. 
Corpus debile, magnitudine minori. Caput parvum, oculi laterales. Palpi 
minuti, supra haud conspicui, 3-articulati, articulo basali valde squamoso (fig. 2 * 
palpus tectus et nudus) 3tio ad apicem subnudo. Mandibule minute distantes ; 
maxille nulla. Ale magne, valde elongate, antice integra, postice incisuris 
semicircularibus inter venas, incisura externa et anali (illa presertim) valde 
elongatis. Hamus et tendines omnino carent. Area discoidalis alarum anticarum 
vix pone tertiam partem ale extendit. Vena mediastina simplex ; vena postcostalis 
ante apicem aree discoidalis emittit ramum simplicem fere ad apicem coste ex- 
tensum ; ex apicesupero et antico hujus are ramum alterum etiam emittit, hic 
ramus ramulos duos superos ad apicem al extensos emittit. Vena ordinaria 
transversa (aream discoidalem claudens) valde angulata, venasque duas simplices 
emittit. Vena mediana brevis triramosa. Cellula discoidalis alarum posticarum 
brevis, vena valde angulata (ramum unicum emittente), postice clausa; vena me- 
diastina simplex, vena postcostalis bifida ramis valde elongatis, externo intra 
marginem incisionis currente ; vena mediana 3-ramosa. 
Pedes crassiusculi, longitudine mediocri. Tibize antic intus spina lata mobili 
instructe, apice inermes ; tibiz intermediz apice bicalcaratee, postice vero, ante 
apicem, ut et in apice ipso, bicalcarate.
