CALLIDRYAS. 2 27 



This genus nearly resembles Catopsilia, but there is no brush 

 of hairs on the wings of the male, though there is a patch of 

 raised scales towards the base of the hind-wings, and the upper 

 radial nervure rises at only one-fourth of the distance beyond 

 the cell. The species inhabit Tropical America, one or two 

 extending as far north as the Southern United States. They 

 are all of a yellow, orange, or red colour, some of them, such as 

 C. solstitia, Butler, from Chili, and C. avellaneda^ Herrich- 

 Schaffer, from Cuba, being blotched with red and yellow in 

 such an extraordinary manner as to look more like clumsily- 

 executed daubs than natural Butterflies. The type of the 

 genus is

This is a common Butterfly in the United States. It measures 

 about three inches across the wings, which are of a fine sulphur- 

 yellow above, unspotted, or with a linear brown border to part 

 of the costa and hind-margin of the fore-wings, and brown dots 

 on the ends of the nervures on the hind-wings. Beneath, there 

 is a brown spot centred with silvery at the end of the cell of the 

 fore-wings, and two larger contiguous silvery spots, in ferruginous 

 rings, on the hind-wings; there are also some irregular brown or 

 ferruginous lines or dots scattered over the under side of the 

 wings. The female is of a somewhat deeper yellow both above 

 and below, with the dark edging of the fore-wings rather broader,
