cJ ? . Patch of iine hairs at each side of base of tongue conspicuous. Genal 

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

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

 veutrally. Eye large. Antenna slightly clubbed in S , not incrassate distally in 

 cJ, end-segment long, rough-scaled. Spines of abdominal tergites and sternites 

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

 anal tuft, ? with a simple truncate one, which consists, as in c?, of stiff (mostly 

 reddishj brittle scales. Forecoxal scent-organ of i feebly developed ; legs slender, 

 hiudtibia with 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 .^piir of midtibia and the short terminal one of hindtibia 

 with a comb of stout spines, which extends on the midtibial spnr from the base to 

 the naked apical point, while it is more reduced on the hindtibial spur (PI. LXIV. 

 f. 8) ; fifth tarsal segment shorter than fourth ; hinder edge of memm of 

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

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

 Macroglo.ssum), the other sliort and obtuse ; tlie armature reminding strongly ol 

 that found in Macror/lossum. 



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

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