space, aud the luteous basal and s. t. space. Teriuiual space like 

 median space. T. a. line very irregularly augulate, a long tooth on 

 vein 2, constricting median space. T. p. line irregularly dentate, its 

 course sinuate. S. t. line traced by a series of buff cuneiform spots, 

 aud the slightly contrasting terminal space. Ordinary spots indefiuite ; 

 orbicular elongate, marked with white scales, centered with gray ; reni- 

 form upright, hardly lunate, and somewhat constricted, inferiorly 

 marked with white. Thorax and head like primaries. Secondaries 

 white. Beneath powder}^; secondaries white, primaries somewhat 

 dusky.

This very pretty species is readily recognized by its irregularly mot- 

 tled appearance, which it is very difdcult to describe. Structurally it 

 is as Mr. Grote suggests very close to rileyana ; the $ autennaj are 

 pectinate and ciliate, the fringes are unusually long, and the fore tibine 

 are very heavily armed, though not so formidably as in the allied species.

Gray: from the base outwardly over theclaviform, across the median 

 space runs a pink shade; beyond the reniform is a similar shading. S. 

 t. space largely whitish before the irregular black s. t. line. Distinctly 

 marked; lines single, black, denticulate; t. a. line with a single deeper 

 inward inflection below submedian fold. Claviform large, distinctly 

 outlined ; orbicular funnel-shaped, the narrow portion reaching t. a. line; 

 reniform narrow, elongate, lunate; all the spots whitish with distinct 

 black annuli. Secondaries fuscous, fringes white. Beneath, white 

 over fuscous; a common black shade line marked on the veins of the 

 secondaries. Thorax and head, gray ; collar with a dark line; patagite 

 marked with pink. 



Expands 37""' ; 1.5 inches. 



Habitat. — Sierra Nevada, California. 



The type from Mr. Edwards' collection only examined. Unfortunately 

 this is a 9 , so the position assigned the species is liable to change. I 

 believe the $ , when discovered, will be found to have pectinate an- 

 tenna. 



The species is easily recognized aud is one of our handsomest Agrotis. 



Since the above was written, the species has been found in some num- 

 bers. There is a bred specimen in the collection of the U. S. National 

 Museum, and Mr. Edwards has several specimens. I do not know 

 whether any of these are males, and Mr. Edwards' collection is at pres- 

 ent inaccessible.
