17<j Lord WaUingliam — Nuiea on 



I Avrote of T. nivosella, AVkr. : — " At the time [when T had 

 Avrorifjly sunk Tamarrha as a synonym of Psccadia] I liad 

 seen only the type of Walker's other species nivosella, which 

 is a ? .•" Had' I used the word "examined'" for "seen" 

 the meaning of the paragrapli would have heen more 

 apparent. 



Mr. Busck is now able to say that T. gelidella, Wkr., is 

 not a Paecacha (as I had supposed), but is congeneric with 

 the type of Tumarrlia, a conclusion which he founds on his 

 study of West-Indian specimens ; and, after admitting the 

 synonymy of his own genus Buhaiaxa, which consequently 

 sinks, he writes it " is evidently the species which Zeller sub- 

 sequently described as Pstcadia exomatella." 



Zeller described (Hor. Soc. Ent. Ross. xiii. pp. 238-40) 



Psecadia exornata (not exomatella) from two males taken at 



Chanchamayo, Peru, witli which he associated under a separate 



description two smaller males from Cuba, all in Museum 



Staudinger. I have a single male from the same Pcrunan 



collection, purchased from Staudinger in 1891, which agrees 



absolutely with Zeller's figure and with his first description, 



and has a smooth head. It seems more than probable that 



the Cuban specimens are not identical with those from Peru. 



I have also a female from Jamaica in which the costal shade 



reaches the base instt ad of beins: broken up into spots ; the 



central band is distinctly continuous witii the costal shade, 



not separated from it, the white patches much more clearly 



defined and separated from each other; this specimen agrees 



absoliit'dy with the type of T. gelidella, Wkr., and is certainly 



not the Peruvian e.rornata, Zell. It may be interesting to 



observe that the locality " Chanchamayo^' is not to be found 



in maps ; the collector Thaum is known to have referred to 



a valley on the eastern slopes of the Andes; " Dr. Staudinger 



schreibt mir dariiber : Thamm sammelte in den Cordilleren 



in einer Hohe von 2000-3000', selten nnch holier, am 



Chanchamayo, einem Ncbcntluss des sich in den Amazonen- 



strom ergiessenden IJcayale, unter dem 12 Grad siidlieher 



Breite" [Z., Hor Soc. Ent. Ross. xiii. 4 (1877)]. " Chancha- 



niayo" is said tomean "Humming-bird" in the local langua;.;e. 



Such confusion is not uufrequcnt among travellers, as when 



Captain Cook tried to ascertain the native name for a 



well-knoMU animal and received the answer " Kangaroo," 



signifying " I don't know Mhat you mean." 



We now come to Tantarrha nivosella, Wkr., the type of 

 the genus, or, rather, the selected exponent when Tamarrha 

 was revived. Zeller, in describing Ins Psecadia adustella, 

 which 1 liavc identified as a synonym of nivosella, Wkr.,
