by light brown edging on both sides. Inferior margin slightly grayish. 

 No black basal dash as in Anguina and Melanopa. Spots at internal 

 angle prominent. The dark shade following t. p. line about same as in 

 Anguina, but somewhat more prominent from the contrasting lighter 

 shade. Hind wings yellowish white, veins slightly dusky. Type i <$ in 

 my collection from Denver, Colorado. This is probably the Western 

 form of Anguina, but it must be quite rare, as it is the only one I have 

 ever received. The typical form I have from Texas, Illinois, Iowa, 

 and Manitoba, as well as the Eastern States. The uniform buff colour, 

 pale secondaries, and lack of the basal dash, present an appearance 

 quite different from the commoner Eastern form. 



Dasylophia Melanopa, n. sp. 



Considerably larger than Anguina, the $ being i and 11-16 inch in 



expanse and the <j> 1 and 15-16. Palpi externally flesh-coloured, bordered 



above and below with dark brown. Vestiture of head and collar 



ochraceous, of a darker shade between the antennae. Patagias dark gray 



with a narrow central black line. Thorax ochraceous centrally in front, 



else dark gray with traces of narrow black longitudinal lines. Abdomen 



evenly coloured, dark fuscous. Lighter beneath. Legs rather heavily 



coated with rich brown hair externally, lighter internally. Fore wings 



have a subquadrate basal flesh-coloured patch, the margin of which 



begins at base of costa, extends in an even gradual curve to where the 



t. a. line crosses median vein; from this point it follows the t. a. line 



downward a short distance and then returns to base of wing. The 



median vein through this space is of a somewhat darker brown. The 



basal space above this patch is of a rich dark brown colour, sharply 



limited externally by the t. a. line. The remainder of the basal space, 



the lower third of the terminal and the whole of the median space is of a 



dark gray colour, rather thickly speckled with black. The costal edge of 



the median space is lightly washed with reddish. A very dark brownish 



shade covers that portion of the wing from the t. p. line to apex, darkest 



along costa, gradually merging into a paler yellowish brown patch below 



and to the outer side. This dark subapical patch extends along the t. p. 



line to the median vein, and seems to be a continuation of the dark basal 



patch, the gray median space cutting sharply through the middle of it. 



Four or five minute yellowish points on costa between apex and t. p. line 



at regular intervals. There are two black spots inside the terminal line 



in the submedian space and two opposite these, external to it. T. a. line
