THE ENTOMOLOGIST. 



difference in structure and an argument in favour of retaining 

 the genus Goniodoma. 



It will now, perhaps, be instructive to glance at Zeller's 

 diagnosis of the two genera in the ' Linnsea Entomologica,' Bd. iv., 

 191. Beitrag zur Kenntniss der Coleophoren. At page 195 we 

 have the following : — 



Coleophora, H. Z. Dup. — Alse anteriores vel lineatae. Cellula 

 discoidalis venas 7-8 emittet. Metamorphosis intra saccum. 



Goniodoma, m. — Antennae penicillatse, flagello nudo. Al£e 

 anteriores (caudate) postice transverse maculatse. Cellula dis- 

 coidalis venas 7 emittet. Metamorphosis extra saccum." 



" Metamorphosis extra saccum " is now disputed by Mons. A. 

 Constant of millierella, and none of the other terms appear 

 precise enough to separate the genus froiu Coleophora. Some of 

 Zeller's further remarks on the venation I am unable to verify; 

 for example " The median nervure ends unbranched (einfach)," 

 and it therefore appeared advisable to give drawings of the 

 venation, and thus enable others to form an opinion as to the 

 distinctness of the two genera. 



Coleophora lineolella. x 4. 



Coleophora lixella. x 4. 



The venation exhibited by Coleophora lineolella seems to be 

 the prevailing type of the genus, with the fore wings comparatively 

 short and broad. Coleophora lixella has the fore wings caudate, 

 the closed discoidal cell much attenuated towards the base, and 

 the 4th subcostal nervule terminates at or about the apex instead 

 of on the costa. In both these species the discoidal cell in the
