Belongs in tlie (jraciUiinti group, but is quite distinct from any 

 form as yet described ; its size and round orbicular at once separate 

 it from allied species. 



Genus Namangana Stand. 



Under this genus Hampson has placed a number of N Am. species, 

 oftentimes very dissimilar in general appearance, which have hereto- 

 fore been found under Pcrigca, Catabciia, etc. The following ap- 

 parently new species we refer to this genus partly from lack of a bet- 

 ter place to put them, and partly because they fit in fairly well with 

 the consors-tcxaua group. They all agree among themselves and with 

 the generic definition given by Hampson in having the palpi upturned 

 with 3rd joint porrect, the thorax clothed largely with scales and the 

 abdomen without tufts, except a slight one at the base; the eyes are 

 naked and the S antennae ciliate. Contincns Hy. Edw. we would 

 also refer to this group; it is entirely misplaced in Amiana Dyar, due 

 probably to Hampson's lack of knowledge of the type species niama 

 Dyar ; this species, of which we possess a co-type, has a very prom- 

 inent, rather truncate process to the front, whereas the front in con- 

 tincns is only slightly bulging and evenly rounded. Until a careful re- 

 vision of the group can be undertaken it is risky to create new genera, 

 and we prefer for the present to place the following species under 

 IVantangana. 



N. PEROLiVALis sp. nov. (Plate I, figs, i, 2.) 



Palpi fringed with black hair outwardly, inwardly ochreous; head, thorax 

 and piimaries olive-green, sprinkled with white and blackish scales; basal line 

 black, single, sinuate, extending 1/2 across wing, followed on the costa by a 

 pale olive spot; t. p. line outwardly oblique, black, rather irregularly dentate 

 with a very prominent inward tooth in submcdian fold, edged inwardly with 

 white and pale olive scaling ; space between basal and t. a. lines mostly paler 

 than rest of wing, shaded with black along costa and irregularly sprinkled with 

 black scales; orbicular a small round olive dot, partially defined by dark scal- 

 ing, often almost lost in the ground color; reniform large, kidney-shaped, well 

 excised on outer margin, not well defined, filled with white and olive scaling 

 and with a dark central streak; on costa immediately above reniform a small 

 black spot followed by a similar whitish one ; from these the t. p. line takes 

 its cotumencement ; it is well excurved around reniform, black, sharply dentate 

 on the veins, forming in the submedian fold a prominent tooth, directed in- 

 wardly and the angle of which is filled more or less with black scaling; out- 

 wardly the t. p. line is followed by some pale olive shading and the apex of the 

 dentations dotted with while; the median space is crossed by a suffused dark
