classification of the Pterophoridce. 11 



Also a development of Mimeseoptilus ; at present I am 

 acquainted with only one species, D. canalis, Walk., 

 Brit. Mus. Cat., 944. 



Makasmarcha, n. g. 



Forehead with projecting tuft of scales. Antennae of male 

 ciliated. Palpi moderate, ascending, slender, terminal joint mode- 

 rate, pointed. Tibia3 simple. Fore wings bifid, cleft from before 

 two-thirds; 2 from near angle, 3 and 4 from point of angle or 

 stalked, 5 and 6 short, 7 from near below angle, 8 and 9 stalked, 

 10 absent, 11 from near angle. Hind wings trifid, 3rd segment 

 without black scales in cilia ; 2 from before middle of cell, 3 and 4 

 short-stalked, 5 and 6 very short, 7 and 8 divergent from beyond 

 cleft. 



Derived, like the two preceding, from MimeseojJtilus, 

 and formed to include M.pluEodactijla, Hb., and a second 

 species, described below. 



Mimeseoptilus, Wallyr. 

 Forehead with projecting tuft of scales. Antennae of male ciliated 

 (I — 1). Palpi moderately long, porrected, 2nd joint with loose 

 rough scales, tending to be tufted above towards apex, or tolerably 

 filiform, terminal joint moderate or short, cylindrical, obtuse or 

 tolerably pointed. Tibia3 simple. Fore wings bifid, cleft from 

 about two-thh-ds ; 2 from about two-thirds of cell, 3 fi'om near 

 angle, 5 and 6 short, 7 from below angle, 8 and 9 stalked, 10 from 

 rather near 9, 11 tolerably remote or rather near 10. Hind wings 

 trifid, 3rd segment without black scales in ciha; 2 from before 

 middle of cell, 3 from before angle, 5 and 6 very short, 7 and 8 

 divergent from beyond cleft. 



This is without doubt the oldest of all the known cleft- 

 winged genera, and is the true typical form of the family, 

 being itself descended from a common ancestor with 

 Agdistis. 



Agdistis, Hh. 



I have here no specimens for examination, and can 

 therefore add nothing to the characters of this genus. 



Cenoloba, Wlsvi. 



I have not seen this genus, though stated to be Aus- 

 tralian. If the extraordinary characters given for it are
