76 REVISION OF XYLOMIGES AND MORRISONIA—SMITH. 
spots are sometimes white, sometimes concolorous with a white annu- 
lus, sometimes yellow powdered, and more rarely with a blackish 
powdering. Usually there is a dusky, rarely black, patch preceding 
the t.a. line on inner margin; but in some specimens this is entirely 
wanting. Secondaries smoky with a dark discal lunule, a dusky fol- 
lowed by a pale median line, and aseries of dusky preceded by paler 
terminal lunules. Fringes long, white, with a smoky basal shade. 
Beneath, primaries dusky to an extra median line, thence pale, whit- 
ish. Secondaries white with an irregular outer dusky line. All wings 
with a distinet, rather small, black or smoky discal spot. 
Expands 27 to 35 millimetres=1.08 to 1.40 inches. 
HABITAT: Alameda County, California, October and November. 
A large series of specimens is in the U. S. National Museum (through 
C. V. Riley), many of them bred and in excellent condition. The 
species is unique in maculation and habitus, and is allied in wing form 
to patalis, in which the strongly retracted head, short thorax, and long 
abdomen also find the greatest resemblance. 
Within a limited range the species is quite variable and is yet so 
characteristic that it can scarcely be mistaken. Thesexualcharacters 
differ from all the other species and are nearest to the patalis type. 
The harpes are abruptly narrowed and bent toward the tip, which is © 
somewhat dilated and has the margin inwardly fringed with spinules. 
The clasper is a single, moderately long, curved, acute hook, arising 
from near the middle of the harpe. 
Dr. Riley has kindly allowed me to publish his species here, to make 
the revision more nearly complete.

Head, thorax, and primaries pale, whitish or creamy gray, the median 
Space of primaries more dusky, sometimes fuscous gray, more rarely 
with a yellowish tinge. Collar with a variably distinct fuscous line near 
tip. Patagiz black at the base of the wings. Primaries with a fine 
black basal streak, sometimes faint or entirely wanting. Basal line 
marked by a dusky or blackish spot in the median space. ‘T. a. line 
rather remote from base, outwardly very oblique and somewhat out- 
curved, reaching the inner margin close to the middle. It is dusky, 
single except on costa, and quite usually marked only by the contrast 
between the basal and median spaces. T. p. line geminate on costa, 
pale between the dusky median space and a dusky costal patch in s, 
t. space; below that single, marked by a series of costal dots or, quite 
usually, only by the dusky median, contrasting to the paler s. t. space. 
In course it is outcurved over reniform, then oblique and somewhat 
incurved to the hind margin very near the t. a. line. Themedianspace —
