We have before us specimens from Merida, Yucatan, contained 

 in the Hebard Collection, which agree absolutely with the original 

 description of miles. The material from Argentina and Paraguay 

 shows certain constant differences which have already been empha- 

 sized by Pictet and Saussure.^^ Any expression of the exact rela- 

 tionship of the material from the two regions seems best withheld, 

 until at least sufficient series from other localities can be examined, 

 thus enabling us to judge more clearly how constant over definite 

 regions apparent differences are. The Merida individuals, seven in 

 number, are constant and typical. All of the Argentine and Para- 

 guayan specimens seen are duller with the pale maculations more 

 orange-rufous than yellow, the wings with the pale areas brick red 

 or orange, the pale occipital bars narrower and the pale areas of the 

 caudal margin of the pronotum usually not continuous, but broken 



28 In studying the present series of this species we have made a rather extensive 

 re-examination of our material of this and allied forms, as well as the literature 

 bearing on the subject. It is in consequence necessary to correct certain previous 

 references which are erroneous on account of a confusion of 7niles and stolli. 

 Bruner's first reference of stolli (Sec. Rep. Merch. Locust Invest. Coram. Buenos 

 Aires, p. 60) should be credited to tniles, as material before us studied and deter- 

 mined by him at that time shows. Specimens of stolli from British Guiana, also 

 from him, we find labelled 7niles in his handwriting. The present author, partly 

 by following these determinations, is responsible for the following misidentifica- 

 tions, which should refer to C. miles.
