DYNAMINE. 155 



after Doubleday's death Dy Westwood, and was illustrated 

 throughout by Hewitson. It is therefore probable that Hewit- 

 son had already commenced the formation of his collection 

 before that time, especially as he began to publish his own 

 "Exotic Butterflies" as early as 1S51, and before the actual 

 completion of the " Genera." 



But to return from this digression, into which the recollec- 

 tion of an old friend has allured us, to the American genus 

 Adelpha. These Butterflies are of moderate size, generally 

 measuring about two or two and a half inches across the wings. 

 The fore-wings are short, and the hind-wings are generally 

 rather long, and sometimes dentated towards the anal angle, 

 which is more or less produced. Most of the species have a 

 transverse white or, more rarely, a green band across both wings, 

 or on the hind-wings only ; sometimes this is reduced to a 

 large spot on the latter. On the fore-wings there is usually a 

 tawny band or large blotch towards the apex or surmounting 

 the white band ; other species have brown hind-wings, and the 

 fore-wings have an oblique red or white band, or a straight 

 ferruginous one. Bates describes them as having a sailing 

 flight over bushes and low trees ; like Limeniiis, also, some 

 of the species will sometimes settle on the ground in moist 

 places. 



The genus Dynamine, Hiibner, occupies rather an isolated 

 position in the series of South American Butterflies. Bates 

 placed it near Pyrrhogyra, and states that the flight is similar, 

 but much weaker, and that the pupa is similar ; but Schatz 

 and Rober refer the genus to the neighbourhood of Limeni- 

 tis, on account of the short bristle-bearing warts, and the 

 absence of horns on the head of the caterpillar, which is 

 shorter and more cylindrical than is usual in the Nymphalidce. 

 Bates describes the pupa of his D. leiuothea as green, with 

 he dorsal surface of the abdomen reddish, and with two short
