YPSOLOPHUS Fabricius. 

 Ypxolophus Fabricius, Supplementuni Ent. Syst., Hafnue, 1798, p. 421, pi. xxxvr. 



Labial palpi long curved, second joint thickened, with dense pro- 

 jecting tuft of long- hairs beneath, sometimes rough above; terminal 

 as long or longer than second, slender pointed. 



Forcwings with 12 veins, 7 and 8 stalked, 2 and 3 stalked; hindwings 

 as broad or broader than fore wings, trapezoidal apex obtusely pointed, 

 tcrmen Mightly sinuate; 8 veins, 3 and 4 connate or stalked. 5 approxi- 

 mate to -t, (> and 7 closel}' approximate, connate or stalked. 



Mr. E. Meyrick made i^othriK Hiibner synonymous with Jjjsolo- 

 phus,^ and the species hitherto placed in that genus in America, 

 which are known to me, conform well with the definition of Ypsolo- 

 phiis, except N'othris malkjemmella Murtfeldt, which is a Blastobasid, 

 lately referred to the genus n<>lcocera Clemens," and Ypmlophus 

 trhmiculelluH Fitch, which has l)een discovered to belong to the family 

 fficophoridic and has been made the type of a new genus E>uiiei/7'icMa 

 Busck.=' 



The other species probably belong in the present genus, but unfor- 

 tunatelj^ some of them are known only from the descriptions, all 

 authentic material being lost. 



By continued breeding of good series of Ypsoloplms, however, all 

 of them may in time be rediscovered, but at present it is not safe from 

 the more or less meager descriptions to even include them in the fol- 

 lowing table, which then onh' contains such species as are recognized 

 at present.
