This iurin luiglit he eoiifouiuled hy a casual ohscrrver with .]f. crrans p.rrroi.s, 

 especially with such sjx'cimeiis of the latter in which the grey median interspace 

 is reduced to two small patches in c(>nse(|ueuce of tlie antemedian and discal bands 

 being merged together mesially. The first and second discal lines of rrraim are, 

 however, straight in front, the abdomen is grey above, and shows dark basal 

 dots also on segments f) and (i (the two dots of the latter segment being often 

 merged together to a large mesial patch), the white side-tufts are larger and 

 the palpi are longer, tlie triangular jiatcli of the mesothoracic tegula is more 

 prominent, etc. 



Lucas's description of ajiproximans applies to .\f. eon/tints pylene as regards 

 wings, to the present species as regards abdomen ; while the abdomen described 

 under M. lineata is that of pi/lene and the wings, we believe, those of the sub- 

 species we have just characterised. Neither of the two names appro.rimans and 

 lineata can be applied (see Introduction, " Nomenclature "). 



Lucas says, I.e., of lineata: "Near M. trochilns, Hubn., M. sitieul, Boisd., 

 M. corythus, Boisd." 



503. Macroglossum nubilum spec. nov. (PI. IV. f. 17, S). 



c??. Resembling M. promethem inusitatn, but is deeper brown, the grey 

 postmedian costal patch of the forewing extended beyond R' towards the distal 

 margin, the distal border of the hindwing convex, twice the width of the yellow 

 band, which widens behind a little. Head without white line above eye, brown 

 triangular lateral area of palpus not sharply defined above ; first yellow side-patch 

 of abdomen just vestigial, second and third prominent, with deep black patelies at 

 the proximal side. 



V^'iugs^, iippersi(/e. Forewing: antemedian lines not conspicuous, not distinctly 



filled in with dark brown, more strongly curved than in prometheus ; first discal line 

 very indistinct, except at costal margin, strongly angulated in front like the second, 

 which is distinct, interspace filled in with brown from costal margin to angle of 

 lines ; grey costal space following this line continued beyond R', reaching more 

 distally R- or even R'' ; sul)api(^al patches SC — R' dark russet, the second blackish 



distally. Hindwing : black basal area continued along SM-, joining the black 



distal border, the yellow band in consequence ])r()ximally convex ; this band not 

 reaching costal edge, at R- barely half the width of the distal border. 



Vndcr.vdp : Mars-brown or mummy-brown, deeper in tint than in M. 

 ]»-ometlii'ns ; tiie yellow aiidominal area of the hindwing very sharply limited 

 distally. 



S. Tenth tergite truncate; sternite rounded-dilated at end. Clasper icitk 

 friction-scales ; harpe short, curved upwards at end, tip acute (PI. L. f. 4G)- 

 Process of penis-sheath (PI. LVI. f. 26) obtuse at end, its dentate base 

 ]irojecting also a little at the left side, the whole process boomerang-shaped ; 

 internal rods obtuse at end.
