GENUS MEGANOSTOMA REAKIRT (THE DOG-FACE BUT- 

 TERFLIES) 



Closely resembling the insects of the next genus, from which 

 they may be distinguished by the more pointed fore wings, 

 and the fact that the rude outlines of the head of a dog are 

 shown in yellow silhouette upon the fore wings. There are 

 two species in our territory, one of which, M . eurydice Bois- 

 duval, found in California, may be distinguished from the other 

 by the splendid purplish iridescence of the fore wings of the male. 



(1) Meganostmna ccesonia (Stoll), Plate CIV, cT (The South- 

 ern Dog-face). (See p. 180.) 



The sexes are much alike in this species, which ranges from 

 Florida and the Gulf States northward as far as southern 

 Illinois. Expanse 2.25 inches. 



GENUS COLIAS FABRICIUS (THE SULPHURS) 



Medium-sized butterflies, yellow, orange, and sometimes 

 white or greenish yellow with dark-bordered wings, the borders 

 generally heaviest in the female. Eggs spindle-shaped, taper- 

 ing at top and bottom, and attached to the surface where laid 

 by a flat disk-like expansion; vertically and horizontally ribbed.
