parallel to tcrraen, middle third thinner, waved, rather abruptly curved outwards, 

 then rectangularly angulated inwards beneath discal spot, lower third much broader 

 and fascia-like, perpendicular to dorsum ; a pale brownish-ochreous streak mixed 

 with whitish connecting dorsal extreniity of this line with lower part of median 

 curve : cilia fuscous, darker towards base, irrcgularlj- barred with whitish, more 

 broadly above middle of termen and above tornus. Ilind-ivings with termen 

 waved, sinuate beneath apex ; dark fuscous ; an irregular white median fascia, 

 broadest in the middle ; a cloudy fuscous-whitish slightly sinuate postmedian line ; 

 cilia ochreous-white, basal half spotted witli dark fuscous. 



One specimen, Molokai, at 1000 feet, in January. This is a very 

 curious insect ; it has the normal structure of Hymenin^ and its 

 specific relationship to H. fascialis h obvious ; it is certainly not an 

 abnormal variety of that species, beinp; quite different in form of wing 

 (especially in the sinuate costa) as well as in markings, but as a 

 derivative species it is certainly unexpected. It is conceivable that 

 it might be a natural hybrid between R. fascialis and one of the 

 native allied (but structurally very distinct) species of Omiodes ; the 

 modification of form and markings is such as might be expected in 

 this case, but this is a mere suggestion, which will be sufiiciently 

 disproved if other examples are taken. 



Mestolobes sicarta, n. sp. 

 i . 18-22 mm. Head, thorax and abdomen dark fuscous, anal tuft pale 

 brownish-ochreous. Palpi fuscous. Leffs fuscous, obscurely ringed with whitish- 

 ochreous. Fore-tolngs rather dark fuscous ; lines obsolete ; a more or less obscure 

 small pale ochreous spot on costa about f : cilia fuscous, with dark fuscous basal 

 line. Hind-toings blackish ; dorsal lobe long, ochreous- whitish, terminal hairs dark 

 fuscous towards extremity ; costal hairpencil whitish-yellowish ; cilia as in 

 fore-wings. 



Twelve specimens, Molokai, at 4000 feet, in "February. An 

 obscure-looking but quite distinct species. 



SCOPARTA GTMNOPIS, n. sp. 

 (? . 21 mm. Head dark fuscous, with a few white scales. Palpi dark fuscous, 

 base white. Thorax orange mixed with dark fuscous, with a few white scales. 

 Abdomen pale greyish-ochreous. Fore-ioings orange, mixed with dark fuscous, costa 

 narrowly, termen and dorsum broadly suffused with dark fuscous, with some 

 scattered white scales ; first line silvery-white, oblique, rather irregular ; orbicular 

 and claviform almost obsolete ; discal represented by some undefined dark fuscous 

 suffusion, preceded by a naked oval patch, in which is a longitudinal narrow cylindric 

 bladdery swelling; second and irregular subterminal lines indicated by scattered 

 white scales; an interrupted white terminal line: cilia pale fuscous mixed with 

 darker and barred with white, with a dark subbasal line. Hind-wings whitish- 

 fuscous, termen narrowly suffused with fuscous; cilia fuscous-whitish, with fuscous 

 subbasal line.
