Imago. — ^$. Sexually and individually variable in the 

 amount of yellow on body and wings. Head and thorax with 

 a distinctly darker mesial line in fresh specimens ; abdomen 

 with three yellow side-patches, variable in size, separate 

 from each other, the first always transverse ; anal tuft black, 

 or tawny only at tip. Fore wing with the antemedian lines 

 straight, basal area darker than the greyish median inter- 

 space, not so dark as in passalus ; first and second discal lines 

 rather far apart, very slightly curved ; third line vestigial, 

 a grey submarginal space from R 1 backwards, often blue in 

 side-light, separated from or almost joined to a small discal 

 costal space of the same colour ; no distinctly marked dark 

 subapical spots. Hind wing : median band deep chrome, 

 base and distal margin black, inner edge of distal border 

 covered by yellow hairs and scales, median veins more or less 

 black, the yellow band often interrupted, especially in <£<£. 

 Underside of abdomen inclusive of tail dull chestnut -hazel, or 

 deeper brown, side -tuft of third segment white ; wings variable, 

 abdominal area of hind wing yellow. Expanse : <£? 50-66 mm.

 long, sole-shaped, rounded and incrassate at end, upperside 

 transversely carinate, somewhat raised in mesial fine. Clasper 

 with friction-scales ; harpe (fig. 91 K) long and pointed, 

 reaching nearly to end of clasper, differing obviously from that 

 of all other species of Macroglossum. Penis-sheath (fig. 91 L) 

 with two internal rods, one produced into an acute point, the 

 other obtuse ; dentate process somewhat variable in length 

 and armature, tip and apical part of distal edge always dentate, 

 proximal edge dentate from base to apex, a number of teeth 

 on sheath near base of process.
