and is irregularly dentate. Subterininal line always distinct, narrow, 

 white, irregularly sinuate arid dentate, best marked in the costal region. 

 A series of somewhat obscure termiiuil spots, interrupted by more 

 prominent wiiite dots. The orbicular is distinct as a white dot iu all 

 the specimens I have seen and the reniform as a narrow upright white 

 streak which is scarcely a lunule or crescent. Secondaries with median 

 and extra-median narrow denticulated white lines, which are variably 

 distinct; iu some specimens a black discal spot is visible. Beneath, 

 black and white powdered, primaries repeating the subterminal and 

 transverse posterior lines, while the secondaries reproduce the macula- 

 tion of the upper side. Both wings have a black discal spot.

This is one of the smaller species, and most nearly resembles E. luhri- 

 w?/.v in wing form; seeming, indeed, only a somewhat further step in 

 the depth of the ground color, and replacing by white the sordid yel- 

 lowish of the pale lines. This contrast, the narrow, usually broken 

 white lines on almost dull-black ground, as well as the white-ringed 

 abdomen, makes this s])ecies easy of recognition. The sexual pieces, 

 so far as they have been examined, resemble U. luhricalis quite closely; 

 but I have not had a male free for dissection. The species is not com- 

 mon and is most usually taken at night in my experience. 



The antenme differ quite obviously from those of E. luhricalis in both 

 sexes. In the male the joints are less marked, the lateral bristles are 

 feeble, not as well developed, indeed, as iu the female of its ally, and 

 there are no piliferous processes or tubercles. A comparatively few 

 hairs rise from small punctures, but they are scant in number and feeble. 

 In the female the lateral bristles are yet further reduced and are hardly 

 more than stout hairs, and we have, thus, an actual and marked struc- 

 tural character sujiplemeuting those drawn from maculation.

 Ground color of head, thorax, and primaries jiowdery blackish over 

 dirty whitish, the latter color visible in the markings. The usual 

 transverse lines are rather prominently defined by the whitish color, 

 but the accompanying black lines are in all cases traceable. Basal line 

 distinctly marked. Transverse anterior line upright, its course irregu- 

 lar, the most i)romiiient modification (consisting of a squared outward 

 bend in the submedian interspace. Transverse posterior line strongly 

 denticulated, its course on the whole a somewhat even and not very- 

 marked outcurve. Subterminal line pale, prominent, irregularly sinu- 

 ate and dentate, a broken, black terminal line, beyond which is a very 

 narrow pale line at the base of the fringes, which are blackish and pale 

 tipped, cut with narrow pale streaks opposite the vems. There is an
