Note. Leptalis Cyra E. Doubleday, Ann. A r at. Hist. xiv. 418. (1844), is probably a Heliconian. 



The scales of the silvery portion of the under surface of the anterior wings in the male of Leptalis Nemesis are 

 exceedingly minute and of rather peculiar form. They do not exceed the sLx hundred and fiftieth part of an inch 

 in breadth, or the four-hundredth of an inch in length. They are heart-shaped, deeply lobed at the base, more or 

 less rounded at the apex ; varying a little in the proportions of the length to the breadth. The lobes at the base 

 project much more than the length of the little footstalk by which they are attached to the wing, which has its 

 origin at the deepest part of the notch between the lobes. It is consequently bent, to allow of its attachment to the 

 wing. These scales are scarcely imbricated. The fuscous chalky spot in the middle of this silvery patch is composed 

 of scales of ordinary form, more erect and more imbricate than is generally the case. 



The form of the scales on the silvery portion of the wings much resembles that of those which are found at the base 

 of the anterior wings in the males of many species of this family, and of the Ileliconida? ; but they want the fringe at 

 the apex, which the latter possess. The variations in the form of the scales will be treated of more fully in an 

 introductory chapter, when, aided by the researches of my friend Mr. A. Ingpen, I hope to give much interesting 

 matter on this subject.
