APHEISSA. 147 



the place where the triangle is attached to the harpagones there is a smaller projection 

 also serrate on its outer edge ; the ventral edge of the harpagones is produced to a point, 

 the upper edge of the projection forming an irregular lobe with a slightly serrate edge. 

 The primaries have a well-defined patch of closely felted scales on the under surface 

 in the angle between the median and submedian nervures, and there is a corresponding 

 patch on the upper surface of the secondaries between the costal and subcostal nervures.

On comparing typical males of A. statira with the various supposed species called 

 Callidryas boisduvalii, C. neleis, and C. jada great differences are observable in the 

 general tint of the upper surface of the wings, and this extends to both sexes ; but on 

 amassing a large series of specimens it is not difficult to select examples blending all 

 these forms together. Though they are not confined to any special localities, occurring 

 indiscriminately nearly throughout the whole range of the species, we note, however, 

 that on the whole the variation is greater in Colombia, Central America, and Mexico, 

 while in the Amazons valley the typical form predominates. 



A. statira is an exceedingly abundant species wherever it is found. Mr. Bates says 2 

 that in the Amazons valley the females are confined to the thin parts of the forest and 

 its margins, where they may be seen depositing their ova on low trees of species of 

 Mimosa. The males congregate by myriads in company with an almost equal num- 

 ber of C. eubule, and a few of all the other species of the genus, on the moist sand 

 or mud on the river-bank. In the height of the dry season (October) very extensive 

 migrations take place. He once travelled with a fair wind on the Lower Amazons
