Reminding one by the yellow tail of .1/. eon/thus J'tUvicaudata, but distinguished 

 by the tail being entirely yellow, the preceding segment being of about the same 

 colour, with a black median patch, and by the different pattern of the forewing.

c??. Geographically, sexually, and individually variable iu the amount of 

 yellow on body and wings; not dilHcnlt to recognise by the pattern of the forewing. 

 Head and thorax with a distinctly darker mesial line iu fresh specimens ; abdomen 

 with three yellow side-patches, variable in size, separate from each other, the first 

 always transverse; tail below yellow or tawny, never all black. 



Wings, iipperside. Forewing with the autemediau lines straight, the basal 



area darker than the greyish median interspace, but 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 W backwards, often blue in side-light, 

 separated from or almost joined to a small discal costal space of the same 



colour; 7iO distinctly marked dark subapical spots. Hindwing: 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 cJcJ. 



L'jtderside variable, abdominal area of hindwing yellow. 



c?. Tenth tergite truncate or rounded at end; sternite long, sole-shaped, 

 r(nuided at end, here iucrassate, upjjerside transversely carinate, somewhat raised 

 ill mesial line. CJlasper (cith friction-scales ; harpe (Fl. L. f. 41) long and 

 jiointed iu all forms, reaching nearly to the end of the clasper, differing obviously 

 from that of all other Macroglossum. I'enis-sheath with two internal rods, generally 

 not visible without the sheath being ojjened, one of the rods produced into an 

 acute jioint (Fl. LVI. f. 40), the other obtuse ; dentate process somewhal 

 variable in length and dentition, tip and apical part of distal edge apparently 

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

 upon the sheath near the base of the process. 



Length of forewing varying from 2U to 30 mm.
