classification of the PterophoridcB. 9 



Heptaloba, Wlsm. 



I have not seen this genus, of which the nenration is 

 not given ; it appears to be also a development of 

 Platijptilia. 



Platyptilia, lib. 



Forehead with tufts of scales. Antennae in male cihated {^ — 1). 

 Palpi rather long, obliquely ascending, 2nd joint loosely scaled, 

 terminal joint moderate, porrected, iiliform, tolerably obtuse. 

 Tibiae simple, or rather tufted on origin of spm-s and centre of 

 middle tibiie. Fore wings bifid, cleft from two-thirds to three- 

 fourths ; 2 from considerably below angle of cell, 3 from very near 

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

 near angle, 11 tolerably remote. Hind wings trifid, 3rd segment 

 with black scales in dorsal cilia ; 2 from middle of cell, 3 from near 

 angle, 5 and 6 short, 7 and 8 divergent from beyond cleft. 



A development of Mimescoptilus, with which it agrees 

 in neuration, and differs essentially only by the black 

 scales in the cilia of the hind wings ; and even these are 

 sometimes very inconspicuous. In P. hemimctra the 

 frontal tuft appears to be absent, and in some other 

 species it is very short. The scaling of the legs differs 

 specifically, as do also the scales in the cilia of fore 

 wings, but these characters appear too indefinite and 

 unreliable for generic subdivision ; I therefore regard 

 Amhlyptilia, Hb., and CnemidopJtorus, Wailgr., as not 

 distinct genera. I have examined about twelve species. 

 I see no sufficient reason for changing the name of this 

 genus (which is not incorrectly formed) to Platyptilus, as 

 suggested by Zeller ; and the same remark applies to 

 AcijMlia. 



Aciptilia, Hb. 



Forehead without tuft. Antennae in male moderately ciliated 

 (I — 1). Palpi moderate, more or less ascending, filiform, 2nd 

 joint sometimes loosely scaled, terminal joint moderate or short, 

 acute. Posterior tibiie simple. Fore wings bifid, cleft from about 

 middle ; 2 from near angle or out of 4 or absent, 3 absent, 5 and G 

 very short, 7 absent, 9 absent, 10 absent, 11 from a point with 8 or 

 absent. Hind wings trifid, 3rd segment without black scales in 

 cilia ; 2 from middle of cell, 3 absent, 5 and G very short, 7 to apex. 



Apparently derived from Lioptilus. I have examined 

 about a dozen species, of which A. galactodactula was 

 the only one in which vein 11 of the fore wings was 

 present ; this is therefore one of the oldest species.
