234 sphingid^:. 



Anterior tibia ending in a thorn, which is mostly covered with 

 scales. Antenna of $ subpectinate, the lateral projections 

 about half as long as the segments are broad dorsally, Pul- 

 villus reduced. Expanse : 80 mm. 



<£. Tenth tergite obtuse. Dorsal edge of clasper internally 

 with the trace of a stronger chitinized longitudinal ridge 

 before end ; harpe with a single, somewhat spoon-shaped 

 apical process, ventral margin shallowly sinuate, upper edge 

 continued dorso-basad, ending in a rather high crest, which is 

 situated below a longitudinal subdorsal fold clothed with long 

 dispersed bristles. Penis-sheath with a conical tooth at end, 

 membrane of duct with a patch of pale spines. 



$. Vaginal plate not strongly chitinized, much wrinkled ; 

 the orifice preceded by a transverse ridge, forming the lower

Genotype : dissimilis (Brem.). 



Imago. — " <£§. Tongue weak, reaching scarcely to end of 

 fore coxa, the two halves separate, but with fringe. Pilifer 

 with bristles. Palpus of £ prominent, smaller in $, second 

 segment not rough-scaled, joint not open. Antenna setifornu 

 side-line almost even in dorsal view in <§ ; feebly constricted 

 at the joints in $, without distinct seriate cilia (Q). Abdomen 

 with large under scales, upper scales long, woolly, no spines, 

 except at edges, but these spines very weak, scale-like. Tibia? 

 spinose ; hind tibia with two pairs of spurs, longer terminal 

 one more than half the length of the first tarsal segment ; 

 pul villus present ; paronychium with one lobe at each side, 

 the ventral lobes being vestigial. Distal margin of wings 

 dentate, costal margin of hind wing concave in basal half, 

 then convex, apex of wing rounded ; frenulum vestigial, 

 no retinaculum. Clasper and eighth tergite without friction- 

 scales" (Roths. & Jord., 1903, p. 337). 



Larva. — Green, shagreened, with pale oblique stripes, which
