confluent yellow spots in the forewing. On the hinclwing the black marking is broader and occupies nearly 



tridachjla. half the wing. — In tridactyla Dew. (36 b), from Colombia, there is a yellow macular band behind the discocel- 



lular of the hindwing, similar to that of Hirsutis liecalesina, and the base of the hindwing is black-brown. 



phagesia. C. phagesia Hew. (36a), from Ecuador, has similar markings; at the base of the forewing there is a 



red-brown stripe, and the spots are larger and dirty white. In the hindwing the area before the apex is trans- 

 parent whitish. 



mecjaleas. C. lliegaleas Godm. S Salv., from Panama, is said to have in the forewing a red-brown base, 6 yellow 



submarginal spots and a yellow oblique band. The hindwing is red-brown with narrow black distal margin. 



schulzi. ■ C. schulzi Hsch. (36 b), from the Lower Amazon, has large yellow spots in the forewing, and the basal 



third red-brown. The hindwing has a median macular longitudinal band and large marginal teeth with yellow 



alexinhoe. dots. In the ^ the anterior half of the hindwing is transparent yellowish, in the $ red-brown. ^ In alexirrhoe 



Bates, from the Uppe'r Amazon, near S. Paulo, the ground-colour is darker red-brown. The hindwing is 



zeuxippe. not yellowish-transparent and the marginal dots are white. — zeuxippe Bates, from the Cupari (a tributary of 



the Amazon), has at the base of the forewing broad black margins. The apex is dark brown, with 3 yellowish 



thornax. spots and red-brown margins. — thornax Bates, from the Upper Amazon, near Tabatinga, has blackish apex 



with 4 yellowish spots and 6 brownish marginal spots. Hindwing with black teeth at the distal margin. — 



butes. butes Godm. d- Salv., from the lower Napo in Ecuador, is said to be similar to the preceding, but to have 



yellowish spots in the apex of the forewing and a broad, dentate black distal margin to the hindwing. — 



Philomela, philomela Godm. & Salv., from Colombia, is said to approximate to zeuxippe, but to have narrower forewing, 



whilst the hindwing is semitransparent with black apex. The black macular band is placed nearer to the lower 



end of the cell. — The last 5 forms all intergrade more or less with one another, being apparently local forms 



still in course of development, so that it is very difficult to refer the transitional specimens to the individual 



infuscata. forms. — On the Ucayali in Peru there is further a pecivliar form, which I call infuscata form. nov. Here the f6re- 



wing is yellow-brown with dark margins and in addition to the black median spot in the cell a roundish spot 



is placed in the end of the cell and 3 — 4 oblong spots in the apical third. The hindwing has 2 macular bands, 



in the disc and at the anal angle. This form recalls Hyposcada rezia. 



hijdra. C. hydra Fldr. (= valera Stgr.), from Venezuela, has blackish forewing with 3 yellow macular bands 



beronilla. and brownish base. The hindwing is red-brown with dark distal margin. — In the somewhat larger beronilla 



Hew. (36 c), from Colombia and Ecuador, the central macular band is absent and the proximal one is not divided 



pannmensis. by a triangular black spot, as in hydra. — The nearly allied panamensis Godm. <& Salv., from Panama, 



has a broad yellow oblique band, in which several roundish black spots are placed. The hindwing is broadly 



black at the apex and distal margin. 



procne. C. procne Godm. d- Salv., from Colombia, is said to have the apex of the forewing black as far as 



the end of the cell, and a broad yellow oblique band, which is divided bj^ a red-brown stripe over the 2. median 

 , vein. 



villula. C. villula Hew. (36 c). This interesting species has exactly the markings and colouring of certain Cera- 



tinia, e. g. praxilla and ocna; but it may be recognised by the angled middle discocellular, resp. not angled 

 lower one. On the under surface the hindwing has a white double spot at the costal margin near the middle 

 and 6 white distal-marginal dots. Colombia. 



15. Genus: Ceratinia Hhn. 



This genus contains numerous species of very varied appearance, mostly of medium size. It may 

 be recognised by the very long cell of the forewing (especially in the ^) with angled lower discocellular, yet there 

 are differences in the neuration even in specimens of the same species. The species of this genus occur from 

 Mexico to Brazil and Argentina. Many forms of the plains are at times very common, whilst others from 

 the valleys of the Andes are quite local and rare. The wing-pattern and colouring in Ceratinia is very varied. 

 Although the Ift/corea-habitus predominates, jet there are also many forms with vitreous or otherwise marked 

 wings, so that similarities to almost all the markings which occur in other Ithomiid-genera may be found. 



poliimnides. C. polymtiides Hsch. The marking is similar to that of Mechanitis polymnia, with broad yellow 



median band, without subapical spot on the forewing and with 2 black-brown zigzag bands in the disc and 



at the anal angle of the hindwing. "Upper and lower surface are without distal-marginal dots. In Central 



vuiiaits:. Colombia. — In menans Hsch., from the same localities, the forewing has moreover 6 yellow distal-marginal 



dots, which are largest in the apex. In the (J the costal margin of the hindwing is lighter and transparent.
