side. To do this, he had recourse to collections, and 

 finding in one of the varieties of Nymphalis {Oharaxes) 

 Fabius (var. Hannibal), a dark brown butterfly with 

 a macular pale fascia on the fore-wings, and an entire 

 one on the hind-wings, he (regardless of the varia- 

 tion in the arrangement of the fore-wing veins and 

 peculiar shaped tail to the hind- wing, still visible in his 

 tattered fragments) , compounded a figure of the upper 

 surface, in which he introduced a spot within the dis- 

 coidal cell, and another in the middle of the costa of the 

 fore-wings, of which there are no traces given in his 

 own fragments, and converted the two short acute tails 

 of the Cliaraxes into the spatulate one of P. Thersander, 

 adding a red lunule on a yellow ground at the anal angle, 

 whilst, as his notes of the under-surface of P. TJiersander 

 had been partially destroyed, he was obliged to depend 

 entirely on his specimen of the Charaxes, which does not 

 bear the slightest resemblance to that of P. Thersander. 



By way of confirming the above statements, and of 

 shewing the manner in which some of Donovan's figures 

 were manufactured, I add the following notes on two 

 other species of butterflies.

In the 'Naturalist's Repository,' vol.iv. p. 120, is pub- 

 lished a tolerably correct copy of the upperside of this 

 species, from Jones (omitting the white dots on the head 

 and thorax, and making the middle spot on the costa of the 

 fore- wings transverse instead of oblique) whilst the under- 

 side is represented uniformly brown, with the exception of 

 three small white dots beyond the middle of the fore- 

 wings, and a submarginal series of ten minute white spots 

 in the fore, and of fourteen similar close to the outer 

 margin of the hind- wings. Jones's figure, however, of 

 the underside, represents the hind-wing as marked with 

 the same broad white macular band as the upperside, 

 preceded by one small white spot within the discoidal 

 cell, followed by a curved row of seven small spots, close 

 to the inner edge of the white fascia, which is followed 

 by a submarginal row of twelve small dots, of which there 

 are only six in the fore- wings. On referring to Donovan's 

 copies from Jones, we find the upper surface alone repre- 

 sented, but on the brown ground of the wings are to be 

 seen several small black dots, with the marginal note :
