paired teeth on the dorsum of the abdomen are much smaller in this 
species. Apices of thoracic and cephalic appendages as in Figure 36. 
Adult— Much paler than nubilalis. The submarginal line is much 
more deeply indented, being similar to that of penitalis. The male 
hypopygium has two small thorns instead of the long stout appendiculate 
thorn which is present in nubilalis (Fig. 42), and the process at middle 
of the clasper is slightly different in shape and more numerously bristled 
(Fig.. 42). The face is not so much elevated at anterior margin as in 
penitalis, but has a slight carina beyond which it is declivitous. Usually _ 
the specimens average smaller than those of the other two species. 
Pyrausta caffreti, sp. n. 
Adult—tThis species closely resemble obumbratilis, the color and 
markings being very similar. The general color of the fore wings of the 
two females before me is a clear straw-yellow, with the markings linear 
and pale brown. The male which I have is badly deformed and the 
wings, owing to their being only partially developed, are darker than in 
the females, having many brownish scales apically. It is not possible to

process, more enlarged; and c, dorsal plate. Female genital seg- 
ments, 
describe the wing markings from the male but those of the female are al- 
most identical with those of obumbratilis, the submarginal line being deep- 
ly indented posteriorly. The male hypopygium is strikingly different from 
that of any of the other three species as shown in Figure 43. The principal 
distinction lies in the presence of three long spines arising from a com- 
_mon base at base of each clasper. In addition to this there are striking 
' differences in the shape of the process at middle of the clasper and in 
its surroundings. The face in both sexes is almost conically produced and
