65. Aplasta, Ilh. 

 Face smooth. Palpi moderate, porrected, with tolerably ap- 

 pressed scales. Antennae in S' evenly ciliated. Thorax glabrous 

 beneath. Femora slightly hairy ; posterior tibis in ^ not dilated, 

 with all spurs present. Fore wings with 10 absent, 11 anastom- 

 osing with 12. Hind wings with 6 and 7 stalked, 8 approximated 

 to cell towards base, diverging from about middle. 



This genus includes only the one species. Its position 

 is doubtful ; it is in some sense intermediate between 

 this family and the Monoctcniadce, not fully agreeing 

 with either, but capable of being classed with either 

 according as the definition is framed. I have regarded 

 it as to be placed here, though the characteristic 

 structure of the hind wings is not very pronounced, 

 and the absence of vein 10 in the fore wings is an 

 exceptional though certainly not an inconsistent feature. 

 This absence proves that it is not strictly a connecting 

 link between the two families ; but it is not improbable 

 that it represents a small lateral offshoot from the real 

 connecting link. 



ononaria, Fuesl. 



6. SELIDOSEMID^. 

 Hind wings with 5 imperfect (not tubular), very weak or obso- 

 lete, 8 usi;ally obsoletely connected with upper margin of cell near 

 base, approximated to it to near middle, vei-y rarely (only in Axia) 

 to beyond origin of 7, or (only in Narraga) anastomosing. 



The neuration of the fore wings in this family is 

 frequently subject to very considerable variation even 

 within the limits of the same species ; and much caution 

 is therefore required in using it as a generic character. 

 It is, however, not equally variable in all species, and 

 even where it appears most inconstant, it seems to 

 remain fixed in certain details. In order to ascertain 

 the limits of variation as far as possiljle, a considerable
