 Kirby, Oit. Lep. Ha. i. p. 70.!. n. 7 (18i:i2). 



S- Tongue weak, reaching to end of foreooxa. Palpus witli open joint. 

 Antennal segments with straight ventral outline (side-view). Spurs not spinose, 

 longer terminal one of hindtibia less than half the length of the first tarsal segment. 

 Distal margin of forewing entire, straight ; hiudwing : anal angle not produced, 

 D- three times as long as D^ Abdomen like thorax, woolly, the tergites rather 

 densely sjiinose all over, the spines long, denser at the apices. Clasper without 

 friction-patch. 



Tenth tergite (PI. XXV. f. 7) not divided, the apical half rather abruptly 

 narrowed, forming a pointed hook, which is, however, not strongly curved down- 

 wards ; sternite mesially membranaceous, laterally stronger chitinised and produced 

 into a slender pointed i>rocess (PI. XXV. f. 7, Xt). Clasper sole-shaped ; harpe 

 consisting of a plate of chitin which is not much raised above tiie plane of the 

 clasper, but is ventro-distally produced into a very long, slender, strongly 

 chitinised process, which curves ventro-distad and mesiad, protruding beyond 

 the ventral edge of the clasper. Penis-funnel dorsally produced into two ])ointcd 

 processes, resembling the tenth sternite ; penis-sheath with a very peculiar 

 armature consisting of a long, strong, curved thorn which is almost vertical upon 

 the sheath (PI. XXX. f. 38).

i. Tongue rather strong, as in carteri, cori/udoni, etc. Palpi compressed, 

 less broad apically in dorsal view than in the allied species, the joint not distinctly 

 open. Antenna thickest between base and middle, the ventral outline even. Spurs 

 not s])ino8e, very long, long terminal one of hindtibia as long as the tibia. 

 Abdominal tergites not spiny, exce]iting edges. Distal margin of forewing entire, 

 apex strongly produced, hinder angle produced backwards ; D^ of hindwing not 

 mnch longer than D\ both very obli(iue, D' nearly twice as long as D*. Clasper 

 and eighth tergite with organ of friction. 

 , Tenth tergite (PI. XXV. f. Id) very long and very slender, slightly 



comjiressed, gradually curved downwards, ajiex rather obtuse : sternite (.Yf) 

 produced into a broad rounded lobe, which is somewhat constricted basally. (Jlasper 

 (PI. XXXIII. f. 18) broadly sole-shaped ; dorsal half of outer surface without 

 gcaling, the naked area covered with dispersed elongate granules, which are smaller 

 and very dense at the incrassate margin of the clasper ; these grannies replace 

 the friction-scales of the allied insects ; the eighth tergite bears a series of large 

 friction-scales on the innerside as illustrated on PI. LVIII. f. 39 ; the harpe is
