INVESTIGATIONS OX SCIAPHILA WAIILCOMIANA, ETC. OO 



In tlie genera that follow after Sciaphila : Sjthaleroptera 

 alpicolaiia, Hiib.; Chcimatophila tortricellct, Huh.; Oxi/p- 

 teron impar, Stdgr.; Exapate congelatella, CI., have like- 

 wise the same form of ovipositor as we see in Sc. WaJil- 

 bomiaiia, and this also occurs in Tortrix {Lophodei^us, 

 Stph.) oxi/acanthana, H.-S. 



Olindia hybridana, var. albidana, Tr., has again the 

 pointed, naked ovipositor as in Sc. minusculana, and we 

 find a qnite similar formation in that of EpJiestia ehitclla, 

 Hiib. But the Olindia ulmana, placed in the same genus 

 with hybridana, has on the other hand an ovipositor totally 

 different from the forms I have already described, which, 

 however, I have not at present space to describe here. 



More detailed investigations, which I propose in time to 

 carry out, will no doubt show many repetitions of the same 

 form of ovipositor in different other genera of Tortricidce or 

 Blic ro-L ep idop)tera . 



At any rate it may already be seen from the few examples 

 above given, that the difference of form of the ovipositor may 

 under circumstances furnish an excellent character for the 

 separation of very closely allied and very similar species, 

 as in our Sc. Wahlbomiana, L., and Sc. minusculana, but 

 that these differences seem less adapted to be used as generic 

 characters, since even in species so closely allied as Sc. 

 Wahlbomiana and Sc. minusculana, the difference in the 

 form of this organ is so great. 



From the investigations above recorded Sc. minorana, 

 H.-S. {inimisculana, Zell.), with its variety incertana, Tr,, 

 must be separated as a distinct species from Wahlbomiana, 

 L., and its varieties, a result, which we shall presently see, 

 is confirmed by other investigations.
