 9, 11 often out of 10, anastomosing or connected with or rarely 

 running into 12, sometimes anastomosing or connected with 10 

 also, rarely absent. Hind wings with 6 and 7 rarely stalked, 8 

 approximated to cell to middle. 



Probably a development of Gonodontis. It is a charac- 

 teristically European genus, though straggling into North 

 America. The position of 6 in both wings is not con- 

 stant specifically. The median spurs are absent in the 

 first five species, which are therefore more recent forms. 

 The name Eiujonia, Hb., is preoccupied by Hiibner him- 

 self earlier in the same work, and cannot be employed 

 here.

 Face with dense projecting scales, or rounded-prominent and 

 with tolerably appressed scales {boisdiivaUaria). Tongue more or 

 less developed or obsolete. Palpi moderate, porrected or sub- 

 ascending, with rough projecting scales. Antemiie in ^ bipectinated 

 to apex. Thorax densely hairy above and beneath, sometimes 

 tending to form slight triangular anterior crest. Femora densely 

 hairy beneath ; posterior tibiae in ^ not dilated, with all spurs 

 present. Fore wings in (? without fovea ; 10 often connected or 

 anastomosing with 9, 11 occasionally connected or anastomosing 

 with 10. Hind wings with 8 approximated to cell to middle. 



The genus markedly approaches Prosopoloplia, and 

 probably originates with it from some earlier form. It is 

 doubtful whether it occurs outside the European region.
