Pupa (Fig. 34).—The pupa is readily distinguished from that of 
obumbratilis by the absence of the blunt protuberance on the head (Fig. 
37, 38). In general it more closely 
resembles penitalis, but the dorsal ab- 
dominal segments. have distad of the 
fine bristles two pairs of minute teeth 
on each side of the median line. These 
teeth are very much smaller in peni- 
talis and obuwmbratilis than in nubila- 
lis. The apical segment in both 
sexes of nubilalis is much narrower 
than in penitalis, as shown in Figures 
30 and 31. In the comparative 
lengths of the maxillae and antennae 
there is but little difference between 
nubilalis (Fig. 35) and penitalis, but 
in obumbratilis the antennae and 
maxillae are considerably shorter than 
in the other two species. 
Adult—tThis species is the dark- 
est of the group, the malé in par- 
ticular being very dark. We have 
figured the wings of the female (Fig. 
39, a). In the male the central band 
of fore wings, the base proximad of 
Fic. 39. Wings of the left side (a) the indented line, and the tip beyond 
Seyret e Metals’ temaic,’ the submarginal line are usually dark 
brown, leaving only two narrow 
notched yellow fasciae, one before and the other beyond the middle. 
The hind wings of the male are much darker than those of the female, 
the only yellow portion being a moderately broad band across middle.
