of the cotypes. It expands nearly 70 mm.; head and pronotum en- 

 tirely black, grooves containing much pubescence; mesonotum with 

 the usual discal reddish spots, hind margin red ; tergum with posterior 

 margins of the segments red; fore wings with the costal margin 

 orange to the end of the radial cell, darker beyond; first and second 

 cross veins not infuscated; basal cell clouded; mebranes at base of 

 both pairs of wings of a bright red. Beneath femora dull red 

 variegated with black especially at the ends; under side of abdomen 

 black with the posterior margin of each segment rather broadly and 

 unevenly margined with red; valve light colored. We present a figure 

 of this specimen. 



In the American Museum of Natural History there are three 

 females from Nevada, one of them labeled Virginia City, like the one 

 described above. They expand from 70 to 75 mm. 



Lately we have received a female collected June 25, 1919, and a 

 male collected June 27, 1919, at Coal Creek, Iron Co., Utah, by Mr. 

 Tom Spalding. 



Four males labeled Los xA.ngeles Co., Cal., July, Collection Co- 

 quillet, are in the United States National Museum and are like the 

 Nevada male described above. Two males from Nellie, Calif., June 

 20 and 24, 1918 (E. P. Hewlett), are in the writer's collection and 

 are darker than the other specimens here mentioned, with the costal 

 margin of the fore wings not as brightly colored and edged with a 

 narrow line of black. The membranes of both pairs of wings are blood 

 red at base as in true crucntifcra. The tergum is nearly all black, 

 while beneath the abdomen and valve are shining red, the former 

 blackened along the sides and at base. Expand 70 mm. This seems 

 to be a variety of cruentifera.
