156 LLOYD'S NATURAL HISTORY. 



curved processes on the back, one at the base of the abdomen, 

 and one near the front border of the thorax. Miiller, as quoted 

 by Schatz and Rober, says the pupa has two short horns on the 

 head, and two strong beak-like projections on the second and 

 fifth segments. Bates does not mention horns on the head. 

 More information is much needed respecting the transforma- 

 tions of the various species of Dynamine. They differ con- 

 siderably, and will probably be sub-divided into two genera. 

 The pupa described by Bates belonged to the first section ; 

 that described by Miiller probably to the second. In those 

 of the first section, the sexes much resemble each other. 

 They are white, with black borders, generally with a blue 

 mark at the base, and with some white spots towards the tip 

 of the fore-wings. On the under surface they are coloured 

 nearly as above, but the margins are interlined with reddish, 

 bordered with pale blue, and there are other reddish lines 

 and markings on other parts of the wings. The hind-wings, 

 except the base and margins, and sometimes a reddish blotch 

 on the costa, are usually quite white beneath. These are 

 among the smallest Nymphalince, some of them hardly 

 exceeding an inch in expanse, and might easily be mistaken 

 for Lemoniid(z or Lyccenida at the first glance. 



The species belonging to the second section are larger 

 insects, measuring from an inch and a half to nearly two 

 inches across the wings. The males are most frequently 

 bronzy-green, with the margins, and especially the tip of the 

 fore-wings, black, with green or white, or more rarely, dull 

 yellow spots. In the male of D. erchia (Hewitson) a great 

 portion of the outer part of the wing is orange. The green 

 varies much in shade, being sometimes golden-green, or bluish- 

 green ; but there are two or three species in which the males 

 are of various shades of bright blue, with narrow black borders, 

 and the tip of the fore-wings broadly black, scarcely, if at
