148 EHOPALOCERA. 



about eighty miles between sunrise and sunset, and during the whole of the journey 

 the air teemed with these butterflies, all crossing the river (there from three to five 

 miles broad) in one direction, viz. from north to south. On the Upper Amazons they 

 settle on the moist sands in dense masses of many yards square, all with wings upright, 

 and closely packed together. 



Mr. Butler's representation of C. jada 9 is far too highly coloured ; the wings are of 

 only a slightly more ochraceous tint than those of the form called C. boisduvalii, the 

 basal half being slightly darker than the outer half. 



ANTEOS. 



Anteos, Hiibner, Verz. bek. Schmett. p. 99 (1816). 



We think it advisable to separate the American species usually called Gonepteryx 

 clorinde and Gonepteryx mcerula from the Old World members of Gonepteryx, and for 

 them Hubner's name Anteos seems the oldest available, and from the three species 

 cited by him we select the second, A. mcerula, as the type. 



Anteos differs from Gonepteryx in several particulars. The costal margin of the 

 primaries has a strongly serrate edge caused by closely-set dentate processes along the 

 costal margin ; this margin too is a simple curve, and not concave in the middle as in 

 Gonepteryx rhamni. The second subcostal branch is emitted close to the end of the 

 cell instead of some way before it, the middle discocellular is not much shorter than 

 the lower instead of being only a third of its length. There are also characters in the 

 male secondary organs. The harpagones are much less pointed, and carry a lobe along 

 the dorsal edge and another internal lobe near the middle of the ventral edge. G. rhamni 

 has a simple dependent lobe from near the end of the dorsal edge. 



Anteos contains the two species mentioned below, which are both common in our 

 country, one of them, A. clorinde, having also a wide range in South America.
