Ulolouche modesta Morr. 



Pr. B. S. N. H., 1874, 144 (Dianthoccia); Grfc., C. E., 1879, xi, 27 (Graphiphora), id., 1881, 

 XIII, 12G (Taniocantpa). 



Mouse gray, rarely more reddish, more often with a blue-gray pow- 

 dering; outer portion of median space darker, umber brown; terminal 

 space usually somewhat paler, more bluish gray. Median lines gener- 

 ally distinct, umber brown. Basal line augulated. T. a. line gemi- 

 nate, the inner part of line often wanting; its course outwardly oblique, 

 strongly angulated. T. p. line geminate, usually rather faintly marked, 

 its course parallel with the outer margin. S. t. line marked by an 

 irregular preceding shade, which is sometimes broken into spots. The 

 orbicular is obsolete; reniform absorbed in the outer dark shade, usu- 

 ally traceable, the inferior portion blackish. Secondaries fuscous, 

 even, fringes paler. Beneath dark fuscous, powdery, with a more or 

 less incomplete outer line and variably distinct discal spot. Head and 

 thorax coucolorous. Expands 1.10 to 1.20 inches (28 to30'" m ). 



Habitat. — New England, Middle States, Canada. 



A quietly marked species, distinguished by the darker brown color- 

 ing of the exterior portion of median space. Two female specimens 

 from Arizona are referred here, but may ultimately prove specifically 

 distinct. The gray is more luteous, powdery. There is little or no 

 contrast between the inner and outer portions of median space, and the 

 primaries seem more elongate. Pending the discovery of the male, it 

 would be unsafe to describe it as distinct. 



HIMELLA Grt. 

 Pr. Ac. N. Sc. Ph. 5, 200. 



Eyes hairy, tibia? unarmed ; vestiture of flattened hair with inter- 

 mingled scales. Frontal vestiture rather smooth, even. Palpi well 

 developed, reaching to or exceeding middle of front. The antennae of 

 male have the joints bead like, furnished with lateral tufts of bristles. 

 The body parts are slight, smoothly scaled, without tufts, the abdomen 

 elongate, especially in the male. The primaries are large, trigonate, 

 with rectangular apices and roundedly oblique outer margin. The 

 harpes of the male in intractata are narrow, elongate, with a rounded 

 tip. Clasper long, stout, corneous, reaching nearly to the end of the 

 harpe and resting in a groove. 



Two species are known which are referable to this genus, and sepa- 

 rable from Tmniocampa by the frail form, large wings, and smooth, 

 somewhat glistening vestiture. They are easily distinguished. 



Intractata is fawn colored, with large, pale-ringed, ordinary spots, 

 faint median and distinct s. t. lines. 



Thecata is dark, blackish-gray, with obsolete ordinary spots, distinct 

 median lines and without s. t. line. The genitalia of the male of this, 

 species will probably be found much like those, of intractata.
