Lastly, Fiscber von Eoslerstamm, who discovered that there were 

 two closely allied species, and after declaring that in Schiffermiiller's 

 Collection in Vienna, under the name of tumidana, S.Y., there were 

 two good specimens of a species which agrees well with the description 

 in the Catalogue, instead of calling tliis species tumidana, S.V., he 

 gives it a new name — rubrotibiella. As he says that verrucella, Hb., 

 is tumidella, 7ik. and Treitschke, it proves that he had not read 

 Hiibner's description, and only considered the figure which, it is true, 

 more resembles tumidella, Zk.,than rubrotibiella, F, E/., but the latter 

 species varies very much, and I have specimens which agree very well 

 with fig, 73 of Hiibner. 



Zeller was also of opinion that tumidana, S.Y., is rubrotibiella, 

 F. E-. ; it is, therefore, strange that both he and Fischer von Rosler- 

 stamm should have retained the name of rubrotibiella under the 

 circumstances. 



As we must restore the name of tumidana, S.V., since it is cer- 

 tainly Hubner's verrucella and rubrotibiella, F. E., we cannot retain 

 Zincken's tumidella, which would naturally produce confusion ; in 

 consequence I propose to name the latter Zelleri, in honour of the 

 great Lepidopterist who worked out the FhycitidcB in so masterly a 

 manner. 



The larvae of tumidana, S.Y., and Zelleri, Eag., are very similar, 

 and may be described as follows : — 



Grreenish-yellow, with a purple tint, more intense on the dorssl 

 region than on the sides, body beneath paler ; the five dorsal stripes 

 blackish-brown ; ordinary spots black, indistinct. Head pale yellow, 

 marbled and spotted with black, mouth brownish. Second segment 

 also pale yellow, with the plate above spotted with black, the dorsal 

 line visible beneath. 



Tumidana, S.Y., has the markings very distinct, dark, and the 

 larva has frequently a strong reddish tinge. 



In Zelleri, Eag., on the contrary, the ground colour is yellower and 

 greener, the longitudinal lines are also nearly obliterated anteriorly. 



Acrobasis angustella, Hb. — Zeller, in the Isis of 1848, created the 

 genus Alispa for this species, which agrees with no other Phycid either 

 in the structure of the perfect insect, or in the habits of the larva. 

 Hiibner, thinking that the name angustella might lead to confusion 

 with angustalis, S.Y., changed it in his Catalogue into gracilalis,yf\nQh., 

 however, has never been employed, as angustalis, S.Y., is a Pyralid. 

 The larva feeds in the berries of Euoiujmus europceus, and is well known.
