mented by a separate little group on the ventral surface 

 of the ninth abdominal segment. The surface of the 

 pupa may be very simple and smooth, and its texture 

 delicate as in Tinea. It may be covered with a most 

 confusing panoply of hairs as in A. spilodactyla, or have 

 various elaborate hooks and processes as in A. acantho- 

 dactyla. In this case one is reminded, in some degree, 

 of the hooks of C. festaliella, but in ^4. acanthodacfyla, 

 these hooks are recurved, in G. festaliella they are directed 

 simply backwards. Apart from its thorough - going 

 retention of micro characters, it is separated not only 

 from Orneodes, but from Chrysororys also, by the extreme 

 reduction of the dorsal head-piece. So reduced is this, 

 that its presence would be doubted in some species, 

 but that it carries with it the eye-covers as in typical 

 micro dehiscence. 



As a sumniary of the facts and deductions herewith 

 presented, I may recapitulate : — 



A correction as to free segments of Limacodidai. 



A correction as to Nolidm not being " macros." 



A suggestion that sundry families of Palesolepidoptera 

 may be postulated as having once existed. 



That a series (from below upwards) of families origi- 

 nated in MicropteryK, or at any rate in Adelids, 

 characterised by a very narrow prothoracic, and a very 

 large head-plate in the pupa. 



That E'permenia and Orneodes are typical members of 

 this series, and probably also Ghrysocorys. 



That Pterop)liorus is not a member of this series, or, if 

 it is, originated very early in it, and reached its 

 present position by an undiscovered route. 



That Coleophora belongs to this series, and was derived 

 from Adelids by a separate route from Tinea, Eper- 

 menia, etc. 



That the Pyraloids (including vaost Tiv eina with Obtect 

 pupffi) form a higher part of this series. 



Whether these proceed onward to Pyrales (and 

 Geometers) is not fully discussed, and left doubtful.
