 TROPiN.E. By Sir George Hampson_, Bart., F.Z.S. 



[Received Februaiy 19, 1918 : Read March 5, 1918.] 



Proboscis aborted or absent ; palpi upturned, oblique or down- 

 curved, the males of the species with the maxillary palpi brush- 

 like and contained in a hollow of the labial palpi usually having 

 the palpi oblique in the male and downcurved in the female ; 

 maxillary palpi small and filiform, well developed and more or 

 •less dilated with scales at extremity, or brush-like and contained 

 in a hollow of the labial palpi ; frons smooth, with tuft of hair, 

 or prominences of various forms ; antennae of male ciliated, 

 laminate, serrate or pectinate with uniseriate bi-anches, the 

 basal joint often dilated and the shaft often downcurved at base 

 with a ridge of scales in its sinus; the build slender; tibise with 

 all the spurs present ; abdomen smoothly scaled. Fore wing 

 narrow ; vein 1 a separate from 16; 1 c absent ; veins 2, 3 

 rarely stalked ; vein 4 often absent or stalked with 5, 3 and 5 

 stalked or from the cell; 6 from below upper angle; 7 absent; 

 8, 9 and often 10 stalked or 9 absent, rarely 10 also absent, 

 8 given off before or after 10; 11 from cell. Hind wing with 

 the median nervure pectinated on upper side ; veins 1 a, b, c 

 present; 2 from near or well before angle of cell; veins 3 and 4 

 sometimes absent, or 3 and 5 stalked or from the cell, 4 often 

 absent, or 3, 4, 5 all present, 4 stalked with 5 or from cell ; 6, 7 

 stalked or from upper angle of cell ; 8 anastomosing with 7 or 

 approximated to it but free. 



The larvte of very few species are known; these live on 

 Graminacece and pupate in the ground in a chamber formed 

 by agglutinated particles of the soil ; Einmalocera depressella, 

 however, is injurious to sugar-cane, the larva feeding in its 

 roots. 



The su1)family is a development from the Anerasticmce — Ane- 

 rastia Hiibn. Yerz. p. 367 (1827), type dignella Hiibn. — from 

 which it differs only in the proboscis being absent or aborted 

 and non-functional. 



The types of the new species are in the British Museum, the 

 species of which the types are in the collection are mai'ked with 

 a t, and those not in the collection with a *.
