upper angle of the cell, which is closed; as one radial is lost and the 

 habitus phycid there remains nothing to associate the genus with the 

 Crambinse, and it will go to the Anerastiinse. 



Ml (6) hind wing widely separated from Sc (8) at the level of the end of 

 the cell, cell closed, female frenulum simple (Ancylolomiini), 

 Fore wing without any indication of notch at middle of outer margin ; R 

 well separated from Sc toward base in hind wing, Ri free in fore wing ; 



M3 lost Euf emaldia. 



Fore wing (in our species) with a more or less distinct notch at middle of 

 outer margin (very weak in Surattha, which has M, present). 

 Base of R widely separated from Sc. terminating practically opposite M,. 



Mesolia. 

 Base of R terminating well above origin of Mi, usually closely approxi- 

 mated to Sc. 



Rj free, notch slight Surattha. 



Rj normally anastomosing with Sc, notch stronger. 



Fore wing five times as long as broad, outer margin strongly 



oblique Pseudoschoenobius. 



Fore wing about three times as long as broad, each half of outer 

 margin of fore wing nearly vertical. 



Upper discocellular long Prionapteryx. 



Upper discocellular very short or absent, Mi normally ap- 

 parently continuous with base of R Mesolia. 



Ml approximate to Sc + R at end of cell or stalked (Crambini). 



A secondary apex developed at M^. the true apex truncate, obscure. 



Loxocrambus. 

 Apex normal, at R3 or R4. 

 Rb stalked. 



Two radials and a medial of fore wing and Sc and a medial of hind 



wing lost Raphiptera. 



Venation complete or practically so. 



Antennae uni-, or bipectinate in male Thaumatopsis. 



Antennas laminate or simple Crambus. 



R5 from cell. 



Ri anastomosing or connected with Sc. 



R2 stalked with R3_5 ; ocelli lost lesta. 



Ra from cell, sometimes imperfectly fused with stems of Ra-j but 

 separate at origin. 

 Ocelli absent ; tongue obsolete, palpi three times as long as 



head Diatraea. 



Ocelli present. 



Tongue present, though weak ; palpi three times as long 

 as head ; Sc of hind wing typically with free part very 

 short Haimbachia.
