The face is produced but little beyond anterior margin of eyes in 
profile, is convex, with an almost imperceptible carina at anterior margin, 
beyond which it is declivitous.. The male hypopygium is as shown in 
Figure 40, the strong appendiculate thorn above middle of. each: clasper 
being very different from the two small thorns present in. obumbratilis. 
The process at middle of each clasper (Fig. 40) is miore like that of 
obumbratilis than that of penitalis. In the specimens before me the sub- 
marginal line in fore wings is less distinctly dentate posteriorly than in 
any of the other three species (Fig. 39, a). 
THE NELUMBO-BORER 
(Pyrausta penitalis Grote) 
Larva.——tThe dark chitinized points on the skin, which form the 
.color pattern on the dorsum and sides of the other two species are not 
continued below the level of the spiracles in penitalis, and the infra- 
spiracular and lateroventral spots are not darker than the surrounding 
skin, though chitinized (Fig. 18, 19, 20). The anterior submedian dorsal 
spots on the abdomen are separated by much more than the width of 
one of the spots as is the case in nubilalis. The prothorax has the small 
chitinized points proximad of the dorsal plate much more evident than in 
either of the other species. 
Fic. 41. Nelumbo-borer (Pyrausta penitalis): 
male hypopygium, one side, and median 
process much more enlarged. 
Pupa.—Distinguishable from nubilalis by the much broader apical 
segment in both sexes (Fig. 28, 29), and the smaller paired teeth beyond 
the bristles on the dorsal segments of the abdomen. Apices of thoracic 
and cephalic appendages as in Figures 32 and 33. 
Adult—Larger than obumbratilis, usually averaging as large as 
nubilalis, 27-35 mm. in expanse of wings. Freshly emerged specimens are 
more reddish than any of the other species included in this paper. The
