Scopoli based his Macroglossum on " stellular um, etc." This " etc." can only 

 mean ///ci/ormis and tityus (or one of them), since he separated apiformis and allies 

 as Aiyeria. Dalman described in 1816 Ilemaris without taking any notice of 

 Macroylossum, and included in his genus only stellatarwm, fiwiformis, and tityus. 

 Hemaris is, therefore, an absolute synonym of Macroglossum. 



cT ? . Geual process large, triangular. Eye strongly lashed. Antenna strongly 

 clubbed in both sexes, hook thin, abrupt ; end-segment long, more or less cylindrical, 

 with some bristles at end ; previous segment also cylindrical, short, or obliquely 

 ]irodnced ventrad with the sense-cone prominent {rubra). Spines of abdomen flat, 

 very strong, proximal ones shorter than long (except on proximal sternites), 

 ruundt'd ; sternite of seventh segment of ¥ with spines at end ; fan-tail large, 

 ex]iansible. Foretibia with a few spines at apical edge, generally concealed by the 

 .-scales ; spur of foretibia long, only a little short of tip of tibia ; merum of midcoxa 

 produced into a sharp jirocess, hindmerum also with process, but this obtuse ; spines 

 of comb of midtarsus not obviously prolonged ; spurs very unequal, long terminal 

 one longer than second tarsal segment ; first segment of hindtarsus shorter than 

 tibia ; ])ulvilli]s well developed or absent, with intergradations ; ventral ])air of 

 paronychial lobes present, or vestigial, or absent. Distal edges of wings entire ; 

 forewing with trans])arent spaces, or at least with a sharply defined marginal band. 

 SC" and R' of hindwiiig from a point or shortly stalked, R- central or a little before 

 centre, cross-veins transverse, slightly curved, R'' and M' always separate. 



c?. Tenth tergite divided, slightly asymmetrical (PL XLIII. f 19— 2(5), some- 

 times the asymmetry more obvious {venata, PI. XLIIJ. f 19) ; sternite either with 

 two long processes, or the right process aborted, the remaining left process more or 

 less asymmetrical (PI. XLIII. f 20. 22. 23). Claspers unequal (PI. LI. f 17—21 ; 

 Lll. f. 4. y), elongate ; no friction-scales ; left harpe (/,//) always vestigial ; right 

 harpe (?■,//) sometimes vestigial, but mostly produced into a more or less club-shaped 

 process. Penis-funnel large, obliquely truncate, or ventrally prolonged ; penis- 

 sheath mostly very slender, ending in a pointed or flattened process, which is dentate 

 at end in one instance (i/racilis), seldom (jcnata) heavy and armed with a dentate 

 l)rojection (PI. LII. f. 5). 



?. Eighth tergite transverse, truncate-rounded, rather strongly chitinised also 

 in middle ; vaginal plate small, proximally membranaceous, vaginal orifice on the 

 left side ; membrane connecting seventli and eightli segments (resp. seventh 

 segment and vaginal i)late) rather long, there being a cavity all round between the 

 two segments, allowing the tail a free movement. 



Ijnrva slightly tapering in front, witli jmie dots all over bearing short setae ;
