31o. Mychonia cervina spec. nov. 



forewing : reddish fawn-colour, palest in the marginal area, darkest in the 

 central ; lines deeper fawn-colour, marked by brown spots on veins ; first from 

 quite one-third of costa to two-fifths of inner margin, bent on subcostal vein, then 

 vertical, edged by a faintly paler line towards base; outer line from five-sixths of 

 costa, oblique outwards and bluntly angled above vein 6, then incurved but nearly 

 straight to two-thirds of inner margin, edged outwardly by a distinct whitish line ; 

 a faint brown cell-spot; costa dotted with pale and dark ; snbmarginal line marked 

 by a white line from costa to angle of outer line ; fringe with basal half reddish 

 fawn, tipped with whitish. 



Hinduring : quite pale fawn-colour, with a faint outer line, dotted on veins, 

 before which the inner margin is rather darker. 



Underside paler, speckled with fuscous ; the outer lines and cell-spots marked. 



Face, palpi, and vertex dark brown ; thorax concolorous with forewing, 

 abdomen with hindwiug. 



Expanse of wings : 20 mm.

As in the Oconeque specimens of aberrations lutea mAJlexiMnea of corticinaria 

 H. S., the outer margin of forewing is hardly elbowed ; so that, though I have 

 described the example as a separate species, owing to the difference in the lines 

 and the coloration, it may eventually prove to be only a form of corticinaria. 



311. Mychonia corticinaria H. S. and ab. lutea nov., flexilinea nov., and 



nigromaculata nov. 



This species is evidently very variable, not only in coloration and markings, 

 but even in the shape of the wings. The type is recorded from Brazil ; this has 

 the excision in the outer margin of forewing well marked. I have seen 2 S S from 

 Loja, Ecuador, agreeing well in this respect. On the other hand, nearly all the 

 Peruvian examples seen are not only larger on the average, but show the excision 

 much less deep, and in some cases entirely absent, the vertical distance from apex 

 to vein 4 appearing greater. This Peruvian form I distinguish as ab. lutea. 

 The species described by me as Asestra ustularia, Nov. Zool. xi. p. 132, $ (1904), 

 from ('hulumani, Bolivia, is, I find, merely a synonym of corticinaria. Asestra 

 albitumida Warr., Nor. Zool. vii. p. 208, S (1000), from Loja, Ecnador, is certainly 

 an aberration. Perusia sitperstes Warr., Nov. Zool. xi. p. 166, S (1004), from 

 Santo Domingo, < 'arabaya, Pern, described from a specimen without perceptible 

 elbow at vein 4, is another aberration, in which the lines are continuous instead of 

 being represented by vein-spots, and the ground-colour is lemon yellow. 



Another form, for which 1 propose the name Jlexilinca ab., agrees with 

 guperstea in having continuous lines, but the gronnd-colour is creamy ochreons, 

 and the lines sometimes end on inner margin in brown blotches as in superstes, 

 or in white ones as in albitumida,
