This is not the Paphia onophis of Boisduval’s published work; but nevertheless the 
species must pass under this name on Dr. Felder’s authority, as he publicly used it several 
years before its inventor, though in a different sense. 
The name actually given to it by Boisduval is P. ewbwna, as reference to the type has 
shown us. 
The original description by Dr. Felder was based upon a specimen from Ecuador, 
whence we also have examples. In these the submarginal spots of the primaries are 
five in number. At the other extreme of the range of the species a less number prevails, 
but there is no specific difference between individuals from these extremes. 
A. onophis is closely allied to A. pithyusa, but the males may be distinguished by the 
base of the wings being bluer beneath; the discal dark band of the primaries has the 
outer edge much more irregular. If we are right in the determination of the female 
described above, it is a very different insect from that sex of the allied species. The 
base of the wings of the former is bright blue, in the latter they are hardly tinted, and 
the spots of primaries are very distinct in A. pithyusa, being five in number and nearly 
white ; in A. onophis only two distinct spots are seen. The undersides present hardly 
any similarity. 
Mr. Champion found this species on the banks of rivers in the forest during the dry 
season, and settled on dung in the pathways; on being disturbed they would fly to a 
tree-trunk.
