ACHEEONTIA, Hubner. 
Acherontia medusa. (Plate XLI. fig. 5.) 
Acherontia medusa, Butler, Trans. Zool. Soc. vol. ix. p. 597 (1876). 
Allied to A. stijx of Northern India, but running to a greater size : primaries above 
with scarcely a trace of longitudinal reddish streaks ; subapical paler area less oblique, the 
intersecting transverse lines less strongly dentated : secondaries with the black bands usually 
closer together, better defined, the inner ones generally extending at least to the third median 
branch : body above darker, the skull-marking on the thorax much darker ; head blacker ; 
abdomen with darker dorsal blue stripe, the transverse bands darker : primaries below with 
the outer border much more dusky; secondaries with the outer band more dusky. Expanse 
of wings 3 inches 5 lines to 4 inches 10 lines. 
Nagasaki [Lewis) ; Yokohama [Jonas) ; Hong-Kong [Bowrmg) ; Shanghai, &c. 
This species and all the Asiatic forms can readily be distinguished from A. atropos by 
the absence of the black bauds on the ventral surface of the abdomen. 
DILUDIA, Grote. 
Diludia discistriga. (Plate XLI, fig. 6.) 
Maerosila discistriga, Walleer, Cat. Lep. Het. viii. p. 209 (1856). 
Brownish ash-colour ; primaries with a broad angulated, dark-edged, dusky central band, 
its outer edge sinuated and followed by a sinuated brown-edged white stripe ; a longitudinal 
whitish streak just above the submedian vein, and above it across the basal area a dusky- 
bordered, Avhitish, angulated band ; a black-bordered apical greyish patch, with dusky centre 
and deeply notched anterior margin ; six white-bordered black spots in pairs, and followed l)y 
single brown spots, near the outer margin ; fringe white, spotted with brown : secondaries 
smoky brown, with ill-defined paler discal belt ; the costal area, base, an abdominal marginal 
streak, and the sinuatious of the fringe whitish : body whitish at the sides, thorax with an 
interrupted black border ; abdomen with central and lateral longitudinal black stripes. Wings 
below greyish, more uniform in tint than above, with two transverse parallel lines and a 
submarginal band dusky ; body below whitish. Expanse of wings 3 inches 5 lines. 
Hong-Kong [Bowrimj) ; North China [Cuming) ; Borneo [Low) ; Java [Horsfield) . 
The type seems to be a dwarfed specimen, unless the example from North China’' 
and those from Borneo are distinct.
