strongly marked seriaria forms; while the rest of the spots, 

 which equal the inner-marginal one in size in seriaria, are 

 obsolete or extremely faint. I should have supposed usti- 

 macula to be a species, but that I have one specimen from 

 Peru with the spot weak, and one with it absent (i, e. ap- 

 proaching typical gladiaria), while, on the other hand, one 

 seriaria from Sapucay, Paraguay, apparently taken among 

 other gladiaria forms, is certainly referable to ustimacula, 

 and another is intermediate towards seriaria, having the 

 large spot of ustimacula with additional small spots on the line. 

 I therefore consider that we have here an example of the 

 " var." of one locality (in Staudinger's terminology) tending 

 to become the " ah." of another. 



Anisoperas pectinata, sp. n. 



c? . 36-38 mm. — Head, thorax, and abdomen concolorous 

 with wings. Fore wing grey-brown, densely striated with 

 fuscous ; costa, especially towards the apex, paler ; inner 

 and outer lines fuscous, conversely edged with leaden grey ; 

 the inner bent on SC, then vertical ; the outer bisinuate, 

 outwardly dentate on veins, with a small white spot beyond 

 it below SC ; a cloudy black cell-spot ; the inner third of 

 central fascia and a siuuous band of the same width beyond 

 it paler, greyer ; subtermiual line dentate, indistinct, finely 

 marked with grey scales. Hind wing without inner line ; 

 outer and subtermiual lines more plainly dentate, the teeth 

 more conspicuously followed by pale dashes on the veins • 

 a pale grey band between the lines. Underside paler, with 

 outer and subterminal lines marked.

The insect is almost an exact replica of A. atropunctaria 

 (Walk.)*, except that the antenna of the <$ is bipectinate ; 

 slightly more crenulate wing-margins and more dentate 

 outer line of hind wing may perhaps also be taken as dis- 

 tinctive. Tetragonodes rufata, Dogn. Ann. Soc. Eut. Belg. 

 xliv. p. 231, is probably a related species, but M. Dognin, to 

 whom I have shown my pectinata, says it has different colour 

 and scaling, the postmedian line of the hind wing more in 

 the middle, &c. Anisoperas jodea, Druce, Biol. Centr.-Amer., 

 Lep. Het. ii. p. 532, t. 98. f. 17, is another pectinated 

 species of the genus.
