they been identical, as I have captured and seen a considerable num- 

 ber of specimens within the past ten years. My four bred specimens 

 were almost identical (referring to Lecontei) in coloration with that I 

 send you.'" While this is, to a certain extent, presumptive evidence, it 

 does not absolutely settle the question, for in the case of Epicallia 

 virginalis (see pi. 3) there are two forms (fig. 2 and 4) which appear to 

 be constant, and yet are produced from the same brood of larvoe. As 

 then we can derive these various forms of Callimorpha Lecontei from 

 each other, by the expansion or contraction of the brown markings, I 

 retain these different forms as varieties, until the accumulation of inore 

 material, being somewhat confirmed in this course by having seen, 

 while in the Eastern States recently, a specimen in every way answer- 

 ing to the C fulvkosta, Packard, except that the costa was brown, as 

 in C. contigiia, Walker. 



Var. C. Lecontei, Boisduval (PL 9, fig. i4). 



Brown and white. Head and prothorax bright yellow-ochre, im- 

 maculate. Palpi yellow, with black tips. Antenna black. Thorax 

 and patagia white, the former with a brown median stripe. Abdomen 

 whitish, with brown dorsal stripe. Breast yellowish. Legs yellow and 

 dusky. 



Anterior wings clear dark brown, with white markings, as follows : 

 A broad basal longitudinal streak, narrowing rapidly as it approaches 

 the anal angle, where the tip is nearly separated into a distinct spot. 

 Three sub-costal spots between this streak and the apex, the middle 

 one of which is the largest, and is slightly connected with the apical 

 one. A large anal spot, supplemented towards the apex of the wing 

 with two small intervenular spots. 



Posterior wings immaculate milky white. 



Beneath, the brown markings are reproduced, but all are suff'used 

 with ochre, especially along the outer margin and costa, while the 

 brown on the inner margin is exceedingly faint. 



Expatise o/'%ings, i .80 inches ; length of body, o. 70 inch.

Described from a specimen raised from the larva by Wm. Saunders, 

 Esq. This larva is described on page 64, ante. 



Var. C. Contigua, Walker. Head and body like C. Lecontei, just 

 described. Legs white, except coxse of the anterior pair, which are 

 yellow.
