tergite (AV/) appears as a long strong hook, while the sternite (Xv) is a small 

 fold ; the length of the tergite as compared with that of /n'ea/it.t can be best seen 

 from PI. XXV. f. '.i. 4. The dorsal lobe of the clasper (IV/) is rather w^^ak, apically 

 dilated and bent inwards, irregnlarl}' ladle-shaped, the ventral lobe ( Vc) ends in 

 two heavy teeth : the najiair process common to both harpes (j>r) is fishtail-shaped ; 

 the lateral processes of the harpe are very unei[nal, tliat of tlie right harjie (pc/J) 

 being long and pointed, projecting be3'ond the ventral edge of the clasper, while 

 the process of the left clasper ( pflr) is short and more or less obtnse. The needle- 

 like process (//) between clasper and tenth sternite very jirominent. 



?. Eighth tergite (PI. XVIII. f. .">) with a sharp prominent cone npon the 

 n]iper surface at each side, pointing distad. Vaginal armature (PI. XVIII. f. 1) 

 with a large postvaginal plate {pvp) which is very prominent : the distal margin 

 slightly bi-emarginate, the mesial portion somewhat i)rodnced and bent ventrad, 

 so that the plate ajipears mesiiilly almost sinnate in an anal aspect ; the angles of 

 the plate ronnded.

?. Only one badly damaged specimen, which is, however, so peculiar in the 

 structure of the co]iulatory organs that we do not hesitate to make it the type of 

 a name for this new snbspeeies Large, general colour nearlv as dark as in 

 frilin. niidatHis, more ashy grey on body and base of forewing ; forewing with traces 

 of a double submedian line wiiich crosses M at tlie base of M', discal line evenlv 

 concave, slightly angled just befiire inner margin. Upperside of mid- and hindiibiii, 

 jinrer white than in umhitus. 



Eighth tergite (PI. XVIII. f. s) with an enormously developed, deeply 

 sinnate, irregularly notched and rugate plate, which is homologous to the two 

 cones (if the tergit(! of //■/////. in></rttii.-<. The jiostvaginal plate (PI. XVIII. f. 4) 

 is also remarkably different in lieinir rather deeply siiin:ite, with the twd lobes 

 ronnded.
