of black scales. The head and thorax are yellow, with a rather dull 

 orange tint, and the abdomen is blackish, except at the tip, where it is 

 tufted with the same yellow hair that is found on the thorax. The prima- 

 ries have the median lines fairly well defined by white or yellowish scales, 

 differing much, however, in distinctness. In all cases they are more or 

 less crenulated, but sometimes the lines are quite broad and distinct, 

 while at other times little, except a series of venular dots can be observed. 

 The basal line is wanting, or indicated only by a pale dot on the costa. 

 The t. a. line is quite distant from base, as a whole with a rather even 

 outcurve; the prominent teeth of the line being directed inwardly. The 

 t. p. line is usually close to the t. a. line, narrowing the median space, 

 and in its general course it is slightly and rather evenly bisinuate. In this 

 case the teeth of the line are directed outwardly. There is an indefinite, 

 pale s. t. shade, carrying a reddish s. t. line, and at the base of the fringes 

 is a blackish shading, sometimes broken up into spots. The ordinary 

 spots are very vaguely indicated. The orbicular is generally of quite 

 good size and yellowish in color, but without defining lines. The reni- 

 form may be entirely absent, or may be indicated by paler scales. The 

 secondaries are black, the fringes yellowish or red tinged. On the under- 

 side the disc of both wings is black, and towards the margin they all 

 become tinged with bright red; most distinctly so toward the apex. The 

 armature of the anterior tibia consists of a series of three outer and one 

 long inner claw, the tibia itself being distinctly abbreviated. Expands

Hab. — Utah, California and Colorado. 



The insect resembles the Texan volupia, differing from it most 

 prominently by the black hind wings and by the tendency to very 

 much darker fore wings. I have no definite locality for the Utah 

 specimens. The California specimens were, I believe, taken in 

 the Yellowstone. One of the Colorado specimens I have had in 

 my collection for several years, perhaps one of the specimens 

 taken by Mr. Bruce in 1888. Mr. Bruce sent me additional 

 specimens a short time ago, with the information that it was col- 

 lected in some numbers, by Mr. T. J. Mason, on the flowers of 

 Riidbeckia. 



It is at Mr. Bruce' s request that I name the species after Mr. 

 Mason. It is rather curious that within the last year two red 

 species with black underwings should have been discovered, the 

 one resembling the Eastern Alaria florida and the other resem- 

 bling volupia. 



A Swarm of Butterflies.— Ocean City, Md., Sept. 13.— About three 

 o'clock to-day, during a northeasterly wind, the heavens became almost 

 black with swarms of huge red-winged butterflies. They moved in a 

 southerly direction. It was fully an hour before the last ones passed over.
