MISCELLANEOUS NOTES. 877, 



Length of hindwing 21 mm. Length of abdomen 32 mm. 



Head jet black with a purple sheen. 



Prothorax and thorax jet black, the dorsum a deep metallic purple ; on 

 the sides of thorax, two dirty yellow, narrow lines, starting from the 

 middle and hind coxse respectively. 



Abdomen deep black, no markings. 



Anal appendages strongly resembling those of a Disparonewa. The 

 superior with a robast ventral tooth, the inferior directed ventrally, 

 apering to the end, somewhat broad at the base and slightly upturned at 

 he extremities. 



Wings: stigma black, stronglj^ braced ; 17 postnodals in the forewing, 

 15 in the hind, ab fails for a short distance, to meet Cu2b in all four wings, 

 Cu2 less than half the wing length. 



1 took this solitary specimen in a dark, rocky gorge occupied by a 

 mountain torrent and only secured it after a rather perilous climb, which 

 1 should not have attempted unless T had previously spotted the insect 

 from above with field-glasses. I find this instrument as valuable to the 

 odontologist as to the hunter after more noble game, both for the purposes 

 of detection and observation.
