connecting Tincegeria with Eretmocera. 8 



of Tincegeria, Arauzona, and Acridura, and remarks that 

 Acridura combines " the characters of the clear wings 

 with those of the Pyrales and Gelechiidce." He further 

 states that, " A careful study of all the genera which 

 seem to be allied to Acridura has manifested a gradation 

 of structure from the dEgeriidce to the Pyrales, on the 

 one hand, and from the 2Egemidce to the Gelechiidce on 

 the other." He goes on to say : " The difficulty of 

 pointing out the resemblance of the ^Egeriidce to the 

 Gelechiidce is nothing to that of determining where the 

 line of demarcation between the two families is to be 

 drawn : thus Tinceyeria is apparently a small form of 

 JEgeriid with long, slender-curved palpi, and a hairy 

 second joint to its antennae ; it is without doubt allied 

 to Arauzona and to Acridura, less nearly to Tinthia, 

 which is close to Mgeria; on the other hand, the 

 Gelechiid genus Exodomorpha (Staintonia, Staud.) is 

 evidently the African representative of the New World 

 genus Tincegeria; indeed, I have hitherto only found 

 one structural character to distinguish them by, namely, 

 the form of the secondaries; yet Exodomorpha chiefly 

 differs from Gelechia in the hairy second joint to its 

 antennae, and the non-indented apex of its posterior 

 wings." 



Thus it will be seen that in the case of Eretmocera 

 (shown in this paper to represent Exodomorpha, 

 Staintonia, and Castorura), Zeller, Staudinger, Stainton, 

 and Meyrick recognise its affinity to the Elachistidce ; 

 while Walker and Butler agree with each other in 

 referring it to the Gelechiidce, and in pointing out its 

 connection with the JEgeriidce, with which Butler also 

 connects the Pyrales. 



It should be borne in mind that the family regarded 

 by Walker as Gelechiidce included the genus Butalis, 

 since referred to the Elachistidce. Thus Walker's opinion 

 was not at variance with those of Zeller, Staudinger, 

 Stainton, and Meyrick. 



Mr. Butler can scarcely have intended to include 

 Butalis, or any other genus of the now generally recog- 

 nised Elachistidce in the term Gelechiidce, for he expressly 

 mentions the indented hind wings of that family, a 

 character not exhibited by Butalis or its allies. 



In the case of (Edematopoda (shown here to equal 

 Atkinsonia), Zeller and Stainton also agree in referring
