48 NOVITATES ZOOLOGICAE XXVl. 1910. 



Tipiilomima, Macrotarsipus, etc., the tarsi are very long ; abdomen usually 

 smoothly scaled, in Oligofhlehia vAih hairy dorsal crests, in Sura, etc., with 

 lateral tufts of scales towards extremity, the anal tuft usually large and spreading, 

 but in Aegeria, etc., the abdomen tapers to a small compressed anal tuft ; in 

 Sannina, Episannina, etc., the abdomen ends in pencils of hair ; whilst in Alcathot 

 and CTyptomima there are long roughly scaled dorsal processes from above the 

 base of the anal tuft ; in Tipiilomima, etc., the abdomen is somewhat constricted 

 at base, in Vespanthedon and Similipepsis it forms a slender pedicel. Forewing 

 more or less narrow and elongate, the apex rounded, the termen obliquely curved ; 

 veins 1 b forked towards base ; 1 c absent ; 2, 3 usually separate, but .sometimes 

 stalked or coincident, and in Tradescanticola veins 2, 3, 4 all coincident ; 4, 5, 6 

 usually well separated, in the Aegeria group veins 4, 5 curved downwards ; 7, 8 

 usually stalked, but sometimes coincident or separate ; 9, 10, 1 1 usuallyfrom the cell, 

 but in Aegerosphecia, etc., 9 is stalked with 7, 8, and in Lenyra 10 also is stalked 

 wth them ; whilst in Callisphecia 9is stalked with 8, and 7 from the cell, and in other 

 genera veins 10, 1 1 arc coincident or become coincident towards the costa. Hind- 

 wing with veins 1 a and b present, 1 c absent, 2 usually from well before angle of 

 cell ; 3 and 5 usually stalked or from a point ; but 3 in Paranthrene, etc., from 

 before the angle of cell ; in Melittia, etc., from nearer 2 than 5 ; and in the Tinihia 

 group almost from a point with 2 ; vein 4 coincident with 3 ; 6 usually from well 

 below upper angle of cell ; and 7 from the angle, but in the Bembecia, Tinthia 

 group 6 usually from much closer to the upper angle of cell ; 8 concealed in a 

 fold and closely approximated to the cell and vein 7.
