444 Rev. F. W. Hors on some new Insects collected in Assam. . 
brunnescenti, linea nigra utrinqué valdé irregulari incluso, maculisque 
parvis nigris in nervos dispositis, apice antico lineis angularibus albis 
maculisque duabus majoribus nigris, apice postico rivulis decem nigris. 
Ale posticæ dimidio basali nigro, apicali pallido nigro-rivulosis. Mg 
bipectinatze, pectinibus mediocribus. Palpi parvi. Lingua spiralis. 
Marille capite duplo longiores. Corpus infrà nigrum. 
A more lengthened Latin description is unnecessary, as the figure is so 
accurate. I need only add, that the wings are of a most agreeable russet 
brown and cream colour, which being formed into the greatest variety of 
different shaped markings renders it almost impossible to describe the insect 
with any tolerable degree of accuracy. It seems probable that the present 
species will at some future time be considered the type of a new genus, as the 
anterior wings are laterally rounded and not scalloped, as is the case with 
several, if not all, of the African species belonging to this group. The only 
insect of my acquaintance with Which it can be compared is Bombyx Lucina of 
Drury, from the vicinity of Sierra Leone.
