124 Mr. A. G. Butler on the 



The lateral tuft-like processes from tlie subtermlnal 

 segment of the abdomen, in males of the ^geriid genus 

 Tinthia (fig. 8) occur also in Morocosma margaritaria. 

 (Cf. Lederer in loc. cit. pi. 14, fig. 7 ; also fig. 7 of my 

 plate.) 



The tufts and brushes of hair found on the posterior 

 legs of such genera as Eiirgphrissa, Tarsopoda and So- 

 pliona (notably also in Mylittia), are evidently not un- 

 known among the Pyrales. (See Idia? scopipes of 

 Felder, in Reise der Nov. licp. cxxxvi. fig. 39 ; cf. figs. 

 1, 2, 17, 20, 21.) 



Thus I have shown that the whole of the marked 

 structural characteristics of the JEcjeriidcB are to be met 

 with among the Pyrales, and therefore it only remains for 

 me to make good my view of the affinity which they also 

 exhibit to the Gelechiidce. 



The difficulty of pointing out the resemblance of the 

 j^geriidce to the Gelechiidce is nothing to that of deter- 

 mining where the line of demarcation between the two 

 families is to be dra^vn ; thus Tincegeria (fig. 18) is 

 apparently a small form of ^geriid with long slender- 

 ciu'ved palpi, and a hairy second joint to its antenna ; it 

 is, Avithout doubt, allied to Arauzona (fig. 9) and to 

 Acridura, less nearly to Tinthia, which is close to j^geria; 

 on the other hand, the Gelechiid genus Exodomorpha (fig. 

 19) {Staintonia, Stand.) is evidently the African repre- 

 sentative of the New World genus TincBgeria ; indeed I 

 have hitherto only found one structural character to dis- 

 tinguish them by, namely, the form of the secondaries ; 

 yet Exodomorpha chiefly differs from Geleclda in the 

 hairy second joint to its antennae, and the non-indented 

 apex of its posterior wings. 



I think, therefore, however conservative our views may 

 be, the similarities of structure occurring between the 

 Clear-wings and the two groups of moths with Avhich 

 I have compared them above, will make it necessary for 

 us to place them after the Pyrales and before the Gele- 

 chiidce.
