Thorax above yellowish shading to olivaceous, the squammation hecoming deep 

 yellowish over the basal abdominal segments dorsally. Middle abdominal seg- 

 ments black ; the two pre-anal deep yellowish. Aual tuft black, with central 

 yellowish hairs ; beneath, the abdomen is black, the yellowish haire of the pre- 

 anal segments extending downwardly at the sides. Legs black ; anterior with 

 pale scales along the tarsi and tibise inwardlj'. Thorax beneath sulphur white; 

 the body seems narrower, more fusiform than in the other species, and tlie squam- 

 mation more depressed. Wings largely vitreous, ornamented as usual, but with a 

 wider terminal band on the primaries than is possessed by H. diffinis. The inner 

 edge of the marginal band is plainly dentate inwardly on the superior interspaces. 

 There is a reddish apical stain as in H. diffinis. Expands 1.65 — 1.70 inches; 

 41—43 mm. 



Hab. — Michigan, Ohio, Texas.

 Size rather large, form stout; black. Head and thoracic region above, obscure 

 yellowish olivaceous ; this color extends over the basal segments of the abdomen. 

 Anteuuie. and legs black. Labial palpi beneath and under thoracic surface, pale 

 yellowish white. At the sides behind the eyes, are linear black shades. Eyes 

 uanowlj' edged above with white scales; above, the palpi are black. Abdomen 

 black, except at base as above noted ; the two pre-anal segments are yellowish, 

 this color extending over the sides, but not obtaining centrally beneath. Anal 

 tuft black ; in one specimen mixed centrally with olivaceouu hairs. Wings 

 largely vitreous; primaries with a very oblique yet rounded outer margin. An- 

 terior wings with an obscure brown costal edging and brown at base, where they 

 show a few olivaceous scales. The discal cell is free; a terminal, very broad 

 brown band, tapering to internal angle and very strongly dentate on the inter- 

 spaces within. The apical and two succeeding nervular interspaces are shaded 

 with red scales within, from the apex downwai'dly and inwardly obliquely, in 

 such a manner that the border on the apical interspace is almost wholly red, 

 while on the two succeeding interspaces the red scales merely touch the toothed 

 edge of the border. Secondaries largely vitreous ; an even, narrow, brown ter- 

 minal border, regularly and shortly dentate on the middle of the interspaces. 

 Base of the wing and internal margin fuscous or blackish. The fuscous basal 

 scales extend along costa very narrowly towards the apices. Five nervules are 

 clearly expo.sed on the pellucid field of the wing. Beneath as above, the external 

 borders tinged with reddish. Expan.se 2.10 inches; 52 mm. 



Hab. — Texas.
