26 LEPIDOPTKRA. 



The pupa has the limbs folded upon the sides and breast ; the whole 

 being enclosed in a hard skin. 



The members of this order are, as a whole, terrestrial, and injurious to 

 vegetation. 



Papilionid.E {Butterflies, or Diurnal Lepidoptera). 



Butterflies may be di.stintruished from moths by the 

 following characters:— In butterflies the antenna; are 

 knobbed;* the body is smaller, especially the abdo- 

 men ; the anterior wings, in all, and the posterior 

 wings in most species, are carried erect when at rest ; 

 the wings of each side are not held together by a hook 

 and bristle. The larva; always have five pairs of pro- 

 legs, and very seldom spin cocoons. The pupa; (chry- 

 salides) are usually angulated. 



The genus Papilio includes the " Swallow-tail " but- 

 terflies of which there are many species. 



Papilio Asterias Drury is a familiar example of this 

 group. This butterfly is black, " with a double row 

 of yellow dots on the back ; a broad band, composed 

 of yellow spots, across the wings, and a row of yellow 

 spots near the Ijind margin ; the hind wings are tailed, 

 and have seven blue spots between the yellow band 

 and the outer row of yellow spots, and, near their 

 hinder angle, an eye-like spot of an orange color with 

 a black centre ; the spots of the under side are tawny 

 orange." The female is larger than the male, and has 

 the yellow spots less conspicuous. The wings expand 

 from three to four inches. (2, 263 ; i, 245). 



The larvae are green, with each segment marked by 

 a transverse band of black, upon which is a row of yel- 

 low spots. When irritated they push from the pro- 



* 1 he antenna: of some butterflies are nearly filiform ; while a few moths (Castnia) ha 

 knobbed antenna:.
