irregular brownish lines crossing the middle of cell; a broad greyish 
patch, beginning just before end of cell, bounded internally by a 
blackish streak, and bounded and crossed externally by two lunulated 
waved transverse lines running from costa to inner margin; two 
similar discal lines, becoming black below third median branch ; 
a very irregular black streak bounding the apical patch, and im- 
mediately below it two interrupted blackish lunules ; a central submar- 
ginal bifid black-edged grey spot ; an ill-defined submarginal streak ; 
a white discocellular spot; outer margin black-spotted ; secondaries 
smoky brown ; abdominal area testaceous ; outer margin dark brown, 
broadest at apex ; a pyriform dark brown streak on abdominal area,

This species.somewhat resembles the preceding in general appear- 
ance; but the outer margin of primaries, instead of being convex, is 
distinctly excavated above external angle. Our example bears a 
label by the collector bearing the following inscription: —“ Acherontia 
spei 3. Only two 2 specimens taken in 1857 (one of them lost). 
I have not observed that peculiar chirping noise; had they chirped 
I am sure I would have observed. Query, Does the ¢ only chirp? 
and the 2 not ?’—W. Gzs.” 
I have not thought the MS. name applicable, and therefore have 
not used it.

Wings above olive-green ; primaries with the base, a broad trans- 
verse band leaving a large quadrate costal spot, a small spot between 
the latter and the base upon inner margin, and an irregular band 
beginning broad at apex, undulated and narrowed externally to 
upper radial, then abruptly and deeply excavated to external angle, 
its inner edge straight and with a pale border, all dark brown; a 
postmedian squamose snow-white streak bounding the broad subcen- 
tral transverse band ; a snow-white point on lower discocellular, and 
two at base; secondaries with the costal area testaceous ; apical half 
of wing dark brown; fringe testaceous: body olive-green, head 
greyish brown; abdomen paler at the sides, with five transverse
