green and dark bro^Yn. They are inhabitants of tropical America 

 and the West Indies, and bnt two species range as far iiorth as 

 southern Texas. The more strikingly marked of these is Colamis 

 juUa, of which figures are here given. It is brownish orange, and 

 sometimes, wlien fresh and perfect, almost red. The wings are mar- 

 gined with black, and a bar of black extends diagonally across the 

 outer and u})per [)ortion of the up})er wing. I>eneath it is tan or 

 rust color with a few darker sliades. One or two faint I'ed spots are 

 located near the base of both wiiio-s. 



Coheiiis delila. 



Our other native species, Cohenis delihi, closely resembles the 

 preceding species, but is without the black markings across the 

 wings, and is paler in coloring. These two insects are very abundant 

 in Mexico, and one rarely receives a box of butterflies from that 

 country which does not contain several specimens. 



Tlie genus Danais comprises a large number of good-sized butter- 

 flies inhabiting almost all portions of the world. Many of the 

 grandest species are natives of soutliern Asia and the Malay Archi- 

 pelago. The ground color of these insects is often brownish orange 

 or reddish brown, Avhile in some of the handsomer species it is green 

 or blue. This color is usually diversified with bars and lines of 

 black, these frequently following the veins and margins of the wings. 

 These butterflies are supposed by naturalists to be protected from
