Ixxviii Abstract of Zeller's 



Sp. 22. Valesianella, Heyden. 

 A single specimen in Von Heyden's collection, from the Valais. 



Sp. 23. CoLUTELLA, F. 



Anterior wings bright yellow, with the costa and inner margin silvery ; palpi as 

 long as the head and thorax together. 



A specimen was in the collection of Fischer-von-R6slerstamm. 



Sp. 24. ASTBAGALELLA, F-V-R. 



Closely allied to Vibicigerella, but with the head and thorax pale yellow, conco- 

 lorous with the anterior wings. 



Mann says that the larva is abundant on Astragalus, near Vienna, but difficult to 

 rear. 



Sp. 25. Vibicigerella, Z. 



At once distinguished from the larger Caelebipennella by the costal streak of the 

 anterior wings reaching to the base. The nearly-allied Astragalella has the head and 

 thorax of the colour of the anterior wings instead of white, and the costal line, which 

 in Vibicigerella is of uniform thickness throughout, is in the former suddenly attenu- 

 ated a little way from the base. Pyrrhulipennella (very much smaller and without 

 shining markings), albicosta (rather smaller and with dirty ochreous yellow anterior 

 wings, and the markings hardly shining), fuscociliella (rather smaller and with 

 blunter anterior wings, and the want of a brown wedge-formed streak), and ditella 

 (which is most like in colour, size and form), have all their antennae annulated brown 

 and white, and not unicolorous white. Vicinella only has, like Vibicigerella, a uni- 

 colorous lash to the antennae, but is very distinct, by its blunt anterior wings being of 

 a lively yellow and destitute of the brown wedge-formed streak. 



This species occurs in several parts of Germany and near Glogau : it frequents 

 Artemisia campestris in diy sandy places, in May and July. 



Sp. 26. Ditella, Z. 



Most readily distinguished from Vibicigerella by its annulated antennae ; also 

 smaller, and the costal streak near the base suddenly expands to twice its original 

 size. 



Discovered near Frankfort-on-the-Maine, by Von Heyden. It flies on barren 

 hills, in June : the larva feeds on Artemisia campestris. 



Sp. 27. Partitella, Z. 



Larger than Vibicigerella, from which it is readily distinguished by its deeper 

 yellow colour, the pale hardly loam-yellow wedge-formed streak, and the strongly an- 

 nulated antennae. Its larger size, pale wedge-formed streak, the costal streak not 

 being attenuated at the base, and the discoidal streak not being continued to the apex 

 of the wing, separate it easily from ditella. The much larger size of the anterior 

 wings aud the length of the discoidal streak separate it from the paler-coloured fusco- 

 ciliella and vicinella, which latter has besides unannulated antennas. 



This has occurred at Jena and near Vienna.
