none of the purplish shade following the t. p. line in our new species. 

 We will deal with the differences in the genitalia of the whole group 

 at the close of the article; the species appears distinctly northern in 

 its habitat and apparently intermediate between warneri (PI. XIX, 

 Fig. 1) and duaria. 



Metarranthis angularia sp. nov. (PI. XXIX, Figs. 7, 8). 



Palpi, front and thorax ruddy-brown, the latter tinged with purplish; a 

 whitish line between the antennae ; wings pale ocherous, heavily and roughly 

 sprinkled and shaded with purple and brown so that the ground color is more 

 or less blotted out, showing, however, in the median area of primaries, the 

 basal area to t. p. line of secondaries and indistinctly in the subterminal area; 

 t. a. line dark, rounded, strongly bent out below costa and slightly bent inward 

 at inner margin, preceded by a broad purplish shade, the remainder of the 

 basal area being very heavily covered with coarse brown scaling through which 

 the ocherous ground color only appears as minute speckles; t. p. line dark, 

 slightly crenulate, forming a sharp angle on vein 4 and then concave to inner 

 margin ; the median space is considerably narrower than in duaria, contrastingly 

 pale although sprinkled with brown atoms, these tending to coalesce and form 

 a median brown shade line crossing the wing between the rather faint dark 

 discal dot and the t. p. line ; beyond the t. p. line a broad purple shade tends 

 to diffuse itself over the entire terminal area leaving here and there ocherous 

 subterminal sprinklings, more marked in worn specimens than in fresh ones ; 

 the usual dark subterminal blotch between veins 3 and 4 may be present or 

 absent; a faint oblique dark shade; fringes deep ruddy purple. Secondaries 

 with a distinct black discal dot and dark t. p. line sharply angled at vein 4; 

 the basal area is ocherous, heavily sprinkled with coarse purple atoms, the area 

 beyond t. p. line as on primaries. Beneath light ocherous heavily sprinkled 

 with purplish-brown especially terminally, the cross lines rather vaguely defined 

 by purplish bands. Expanse $ 32 mm., 5 40 mm. 



Habitat: $, Decatur, 111. (June); New Brighton, Pa., (June 4); Pa., 

 ?, no locality, (probably New Brighton, Pa.) (June 3, 1900). 4 #, 2 $ 

 Types, Coll. Barnes. 



Distinguished from the ruddy forms of duaria by the angulate t. p. 

 line and the narrower median space which in the type $ from Decatur 

 is very much constricted ; the coarseness of the sprinkles and the paler 

 median space also give the species quite a characteristic appearance ; 

 judging by our dated material its time of flight is slightly later than 

 that of duaria. 



With regard to the $ genitalia we have examined obfirmaria 

 Hbn., warneri Harv., duaria Gn. and our two new species and find that 

 they show great similarity to one another and that it is only possible 

 to differentiate even such well marked species as obfirmaria and duaria 

 by slight points of difference in the structure of what Pierce has termed
