_ is thus very narrow at that point and, broadening to the costa, roughly 
V shaped. S. t. line punctiform, consisting of a series of interspaceal 
black spots. These spots are variably distinct, sometimes punctiform, 
and occasionally obsolete. In the latter case the terminal space is 
dusky. Thespotopposite anal angle is often more or less yellow shaded. 
A series of small terminal lunules. Claviform small, black-ringed, 
concolorous with the median space, not prominent. Orbicular large, 
pale, oval, oblique, incompletely black-ringed, often fused inferiorly 
with the large, pale, upright, kidney-shaped reniform, which is very 
narrowly black ringed. Secondaries pale fuscous, whitish toward base. 
A vague discal spot and a more evident broken terminal line. Beneath, 
primaries smoky, white powdered toward outer margin, with a faint 
exterior line and a series of terminal lunules. Secondaries white, pow- 
dery, with large discal spot, an even exterior, and a narrow marginal 
dusky line. 
Expands 30 millimetres=1.20 inches. 
HABITAT: Vancouver; California, Los Angeles County, April, June, 
November; Alameda County, May, June, November. 
Rather a common species, of which a large series is in the U.S. Na- 
tional Museum (collection of J. B. 8. and through C. V. Riley), many of 
them numbered 248 in red ink. 
The species varies but little. The ordinary spots are usually fused, 
and the median space is usually dusky. Rarely the maculation will be 
almost entirely obsolete, and from this point all atoneraes to the nor- 
mal type are found. 
A typical specimen of X. fletehert Grt.,is in the Mazer received 
from Mr. Fletcher. It does not differ in the least from the normal pa- 
talis. 
In sexual characters the species is unique. The harpes are centrally 
narrowed, then the tip gradually enlarged, somewhat lappet-like and 
inwardly fringed with spinules. The clasper arises near base, is single, 
stout, slightly curved, moderate in length and obtusely terminated.

‘6? Hyes hairy. Head and thorax in front whitish-gray; collar with 
a black line; a black line between the antenne; front fuscous. Fore- 
wings gray, shaded with blackish. Ornamentation very like Lithophane 
tepida, for which this species may be mistaken, but the yellowish white 
abdomen is rounded, not flattened. The transverse lines are double ; 
basal half-line dentate, consisting of a black inner line and pale outer 
Shade. Basal space gray; subbasal space wide, blackish. T. a. line 
with the outer component line most distinct, pale-centered, upright, 
waved, dentate on submedian vein, running close to orbicular. The 
¢claviform spot large, narrowly and incompletely margined with black, 
With the orbicular whitish gray; orbicular not closed on median vein,
