connecting Tincegeria ivith Eretmocera. 9 



sufficient grounds for separating this species from the 

 genus Tincegeria. 



(Edematopoda, Zeller, possesses all the structural 

 characters relied upon by Stainton in defining his genus 

 Atkinsonia ; the strong scaling of the spurs occurs again 

 in this genus, and in this character, as in the long 

 elevated fringe of the antennae, it is merely a question 

 of degree as between Zeller's and Stainton's types. 

 Eretmocera ignipicta, Butler, agrees entirely with 

 (Edematopoda, and is separable from the true Eretmocera 

 by the shape of the discal cell in the fore wings, as 

 well as by the characters mentioned above, which do not 

 occur in that genus. 



In Trans. Ent. Soc. Lond., 1881, p. 271, I have 

 already pointed out that Staintonia and Exodomorpha 

 can only be regarded as synonyms of Eretmocera ; to 

 these must now be added Castorura, Meyrick, Without 

 committing Mr. Meyrick to any approval of the classi- 

 fication suggested in this paper, so far as regards the 

 affinities of the different genera, I may mention that he 

 quite concurs in regarding Castorura as identical with 

 Eretmocera. 



Felder and Rogenhofer figure, in the * Eeise Novara,' 

 the following species under the name "Eretmocera?" : 

 — E. ceneicepSy which is obviously Tincegeria ochracea ; 

 E. sesioides, which is certainly Snellenia lineata ; and 

 E. flavipennis, the figure of which differs from that of 

 sesioides only in its more yellow colour, in the dark 

 veining of the anterior wings being interrupted by a pale 

 space across the middle, and in the colour of the abdo- 

 men, which in sesioides is figured of a uniform dark 

 tinge, and in flavipennis is yellow, with the apex only of 

 a darker colour. 



The figures are not satisfactory but they indicate 

 these points of difference with sufficient clearness ; and 

 in the letterpress the locality iox flavipennis is " Amer. ?," 

 of sesioides, " Sidney." Snellenia lineata^ sesioides is 

 from Sydney, Australia, and is so labelled in the British 

 Museum, as in my own collection ; but, in describing 

 the species. Walker states that his specimens were from 

 " Para, Bates' coll." This, although evidently an error 

 as regards the actual specimens now existing, seems to 

 increase the suspicion, founded upon Felder's " Amer.?," 

 that a somewhat similar species does occur on the
