incomplete line margining the patagiie. Primaries with tbe median 

 lines jiractically obsolete, the t. a. line traceable only by a single loop 

 below theclaviform and the t. p. line marked only by geminate costal 

 dots. A basal black streak, to which is attached the loop-like clavi- 

 form. The cell is black around and between the ordinary spots, which 

 are connected; an unbroken black line margining both. Orbicular elon- 

 gate, with a slightly darker core; a narrow^ sj^ur extending to the ren- 

 iform, which is moderate in size and kidney-shaped. A black spot be- 

 low reniform. The s. t. and terminal spaces are ])rominently marked 

 by the four pale streaks so characteristic of the 4,dentata series of this 

 genus; the black intermediate dashes distinct; no distinct s. t. line. 

 Secondaries clear, pure white. Beneath white, somewhat powdery, 

 withont line or spot. 



Expands 33""" ; 1.32 inches. 



Habitat. — British Columbia, Spencer's Bridge. 



The type is a unique male from Mr. Neumoegen; easily distinguished 

 from all the members of the group by the united ordinary spots and 

 elongate orbicular.

Ash gray, with somewhat darker shadings through center and iu 

 terminal space. Orbicular oblique, open superiorly ; reniform oblique, 

 elongate, somewhat constricted iu the middle. Both the spots are de- 

 fined by a narrow, black line and a pale interior ring; else concolorous. 

 Claviform very distinctly outlined. Transverse lines faint, in one 

 specimen entirely obsolete. T. a. line geminate, visible only iu sub- 

 median space. T. p. line not traceable at all. S. t. line white, indefi- 

 nite, indented to half the extent of terminal space on veins 3 and 4. 

 Ai)ex pale. Secondaries white, with blackish terminal line. Beneath 

 white, primaries rather densely, secondaries sparsely powdered with 

 black scales. Head and collar interiorly paler ; else thorax concolorous. 



Expands 30-38""" ; 1.45-1.50 inches. 



Habitat. — California, Colorado, Nevada. 



A very peculiar species, recognizable by its burly form and un- 

 usually short abdomen. The head too is somewhat retracted, but iu 

 other respects it does not differ from the other species with which we 

 have placed it. There are several specimens in the collection of the 

 U. S. Natioual Museum, taken by Mr. Bruce in Colorado.
