120 LLOYD'S NATURAL HISTORY. 



in many cases where such inaccuracies are suspected, the 

 suspicion has only been occasioned by attempting to fit a 

 description or figure to an allied form from a different locality, 

 and that, when one gets the right insect from the true locality, the 

 author and draughtsman proved to have been more accurate 

 than was supposed. By applying this rule I have often been 

 able to re-e ; t:blioh disputed species, the identity of which had 

 been considered insoluble, and I am therefore inclined to believe 

 that when an author condemns a description or figure as 

 inaccurate, the fault is at least as likely to rest with the critic, 

 as with the original describer or artist, though I once met 

 with extraordinary discrepancies in figures made from the 

 same specimen by different artists. 



GENUS ILEMATERA. 

 Hfcmatera^ Doubl., Gen. Diurn. Lepid., p. 231 (1849); Schatz, 



Exot. Schmett., ii., p. 149 (1887). 



This is a small genus, containing only two South American 

 species, much resembling Catagramma, but with rather shorter 

 fore-wings and more slender antennae. The hind-wings are 

 mottled beneath, without the sharply-defined markings which 

 are so conspicuous in Catagramma. 



H^MATERA PYRAMUS.

 Drury, 111. Exot. Ent., iii., pi. 23, figs. 3, 4 (1782) ; Stoll, 

 Suppl. Cram., pi. 32, figs. C. C. A. (1790).

(Plate XXL, Figs. 3, 4.) 



This prettily-coloured Butterfly measures about an inch and 

 three-quarters between the tips of the wings, or rather less. It 

 is blue-black above, with a broad curved scarlet band, which 

 extends to about the middle of the hind-wings. On the under
