THE CANADIAN ENTOMOLOGIST. 251 



Mrs. Peart made drawings of both Eros and Coalburgh Disippus 

 larva?, after 4th moult, and at same time, and writes me, that in addition 

 to the remarkable difference in the processes on 3, the crests of the dorsal 

 tubercles on Eros are composed of much larger grains and in greater 

 number than in Disippus. She says : " The horns and the clusters of 

 rice-grains, and the color of body are the chief points of difference." 



Certainly a form which presents so conspicuous and permanent differ- 

 ences from Disippus, not only in the imago, but in the larval stages, is to 

 be ranked as a distinct species. 



I only know of Eros being taken in southern Florida, and it is the 

 only form flying there so far as I know. Examples of Disippus, almost 

 as dark as Eros on upper side,* come from northern Florida, and the 

 Gulf States to Texas, but in these the under side of secondaries is but 

 little darker than in many northern examples. (There is a strong con- 

 trast in Disippus in the color of the two wings below, secondaries being 

 yellowish). Whereas in Eros both wings are of one red hue on under side, 

 much like that of cherry wood. 



On turning to the plate of Disippus in Boisduval and LeConte, which 

 is taken from Abbot, I have little doubt that Eros furnished the examples 

 from which the female represented was drawn. The shape is not that of 

 the northern Disippus, as appears most decidedly by the figure of the 

 under side, it being greatly broader, the fore wings less tapering, and so far 

 this figure agrees with Eros. The colors are not deep enough for Eros. 

 but apparently the under side is intended to be of an uniform shade. 

 And inside the black cross stripe seem to be white crescents, very slight 

 and half obscured by red paint in my copy, but they are dotted out by 

 the engraver. In the text nothing is said of these crescents. The figure 

 of the mature larva is roughly done, and can only represent the end of 

 the stage after the colors have all changed, but the processes on 3 are very 

 long and tapering, with separated spurs, and agree pretty well therefore 

 with Eros. Boisduval refers to Fabricius, Ent. Syst. iii. 50 (Misippus), 

 which merely says: "alis repandis fulvis ; margine nigro albo punctato, 

 posticis arcu nigro," and this is understood to cover the northern 

 Disippus.
