The uncus is black. Beneath the legs are almost entirely light in 

 color blackened at the knees, the abdominal segments are covered 

 with much short hair; are reddish straw-colored margined anteriorly 

 with red. In addition each segment has two dark colored basal 

 blotches more or less connected, one each side of the center. The 

 valve is dark colored on the lower surface, lighter near the upper 

 margins, and when viewed in profile it does not extend as far beyond 

 the end of the uncus as it does in vandykei and ornata.

In the collection of the American Museum of Natural History 

 there is a male labeled " Nevada." We have also examined a male 

 from Hood River, Oregon, June 10, 1916, in the collection of the 

 Oregon Agricultural College, and a female from Blue Canyon, Calif., 

 Tune 7, 1909 (Ball), in the collection of Dr. E. D. Ball. In the 

 writer's collection there are two males and one female from Sonoma 

 Co., Calif., one of the former being the allotype of the species, and 

 a male from Keddie, Plumas Co., Calif., June 28, 1918, 3.500 ft., 

 collected by Mr. Frank M. Jones of Wilmington, Delaware, who 

 kindly presented it to me. This is a very bright and contrastingly 

 colored species. Mr. Van Duzee states " This species may be recog- 

 nized by its black, almost immaculate upper surface with bright 

 orange venation."
