III. On synonyms of Heterocei'oiis Lepidoptera. By 

 Arthur G. Butler. 



[Read March 3rd, 1880.] 



In the hope that the following notes on synonyms may 

 prove useful to Lepidopterists I venture to publish them ; 

 and, much as I must deprecate the want of care which has 

 been the cause of their creation, I nevertheless am willing 

 to believe that the authors who have thus sinned will in 

 future take more pains than they have hitherto done to 

 prevent a repetition of the error. 



Whilst correcting the specific names applied for a 

 second time to the same insect, I think it Avill be advisable 

 to help one writer whom I here criticise to an identifica- 

 tion of the genera to which his other species are refer- 

 able. As it is not conceivable that any Lepidopterist now 

 living can honestly desire to restore the nomenclature to 

 the simplicity of almost Linnean times, and as nevertheless 

 species have been referred by Herr Snellen to the typical 

 genera of families (such as Euj^roctis, Limacodes, &c.), 

 Avhen the insects described are manifestly not closely allied 

 to these genera, I can only suppose that this Entomologist 

 is Avaiting for the identifications in order to classify them 

 in their proper groups. 



At present I regret that I have only time to note the 

 synonyms in one of Herr Snellen's most recent memoirs, 

 I refer to that on the Lepidoptera of Celebes (Part II.), 

 in the Tijdschrift voor Entomologie for 1879, pp. 61 — 

 126. 



Nyctemera latistriga, Snellen (PI. VI. fig. 5), is pro- 

 bably N. lacticinia of Cramer, and certainly not N. latis- 

 triga of Walker. 



Nyctemera ahraxata, Snellen (fig. 6), is Pitasila guttu- 

 losa of Walker. 



Cltalcosia appendiculatn is a Heteropaa, scarcely differ- 

 ing from H. scintillans of Walker. 



Aganais vitessoides is a Hypsa close to H, silvandra of 

 Cramer. 



Digama piepersiana is probably the female of D, mar- 

 morea.
