c? ? . Patch of fine hairs at each side of base of tongue conspicnous. Genal 

 process acuminate, longer than pilifer. Palpus prominent, second segment widened 

 from base to apex, rounded-truncate at end ; inner surface of first segment carinate 

 ventrally. Eye large. Antenna slightly clubbed in ? , not iucrassate distally in 

 S, end-segment long, rongh-scaled. Spines of abdominal tergites and sternites 

 numerous, in several rows, all elongate, flattened, strong ; c? with three-cornered 

 anal tnft, ? with a simple truncate one, whicli consists, as in d', of stiff (mostly 

 reddish) brittle scales. Forecoxal scent-organ of c? feebly developed ; legs slender, 

 liindtibia witli dorsal and ventral scaling prolonged, the tibia appearing compressed; 

 first protarsal segment with external row of spines doubled or trebled ; comb of 

 mid- and hindtarsus strongly developed, the spines of hindtarsal comb long ; spurs 

 very unequal, the short sjji<r of midtibia and the short terminal one of hindtibia 

 with a rom/j of stout spines, which extends on tlie midtibial spur from tlie base to 

 the naked apical jjoint, while it is more reduced on the iiindtibial spur (PI. LXIV. 

 f. 8) ; fifth tarsal segment shorter than fourtli ; hinder edge of merum of 

 midcoxa carinate, subangnlate. Distal margin of forewing entire ; D- of liindwing 

 curved or angulate. 



<$. Sexual armature nearly the same in all the species ; no ajipreciable 

 difference in these organs between allied species. Tenth tergite very slender, 

 simple, curved downwards, long ; sternite short, horizontal, with almost parallel 

 sides and rounded apex, not strongly chitinised (PI. XLIV. f. 'JO. 30). Olasper 

 sole-shaped ; large friction-scales arranged in one or two rows (PL LVIII. f. 38) ; 

 harpe (PI. IL. f. 36) ending in a sharply pointed, more or less evenly curved 

 hook. Penis-sheath (PI. LV. f. 35) armed at end with two dentate processes, 

 the proximal one long, curving round the mouth of the sheath (as in several 

 MacrogloHSum), the other short and obtuse ; the armature roiuiiiding strongly of 

 that found in Macroglossum. 



? . Eighth tergite truncate-sinuate. Vaginal plate small, weakly chitinised, 

 excepting postero-lateral edges which are somewhat incrassate ; orifice free, a little 

 projecting. Seventh sternite broader than long, apical margin short, with strongly 

 rounded ansles.
