This little butterfly can be distinguished from all others de- 

 scribed here by its small size, as it expands only from less than 

 one inch to one and one-fifth inches. It is of a pale canary- 

 yellow color, with dark-brown markings. There is a large 

 apical patch on the fore wings, and a broad band parallel with 

 the inner margin ; on the hind wings there is a stripe on the 

 basal two-thirds of the costa, and spots on the ends of the 

 veins ; these are more or less connected on the margin of the 

 wing, especially in the female. 



Caterpillar. — Length, one-half inch; body covered with 

 stiff hairs ; color, dark green with a broad purple stripe down 

 the back and a double stripe of yellow and black along the 

 side. The segment next to the head has a pair of cone-shaped 

 bristly tubercles, reddish in color and projecting forward. 



Food-plants. — The fetid marigold and garden marigold.

 case of the female the yellow deepens to orange,

 color contrasts of the oriole. The species is at
