164 PACHYTERIA FASCIATA. 



the identification of the true Fabrician species , regarding 

 an undescribed species as such. Nevertheless I wrote to Mr. 

 Gahan of the British Museum asking him to inform me 

 whether Pachyteria fasciata Fabr. is represented in the Bank- 

 sian collection or not '), calling moreover his attention upon 

 the most striking distinctive characteristics between the spe- 

 cies which I believed to be the true fasciata Fabr. and the 

 one which was regarded as such by Thomson. In answer 

 to these inquiries Mr. Gahan kindly gave me the following 

 results of his observations on Pachyteria fasciata Fabr. : 



»You had no doubt correctly determined this species, 

 and it is not the one so named in Thomson's collection. 

 I cannot affirm that the type of P. fasciata Fab. is in the 

 British Museum collection , but there are two specimens 

 bearing that name in the collection of Banks: there can 

 be no doubt that these are correctly named, and it is not 

 improbable that they may have served as the types. Thom- 

 son's fasciata is , I dare say , identical with the Pachyteria 

 fasciata of Dejean's collection — a species for which I had 

 suggested the name of P. Dejeani." 



As Pachyteria fasciata Fabr. is , up to this day, only 

 very unsatisfactorily described , whilst no description what- 

 ever is published of Thomson's and Dejean's /asa'a to, I 

 will now proceed to describe both species, giving to the 

 latter, which was incorrectly identified by me as Pachy- 

 teria voluptuosa Thoms., the name of Pachyteria calumniata.
