The Falcate Orange-tip, AnthocJiaris genutia (An-thoch/- 

 a-ris ge-nu'ti-a). — In this species the apex of the fore wings 

 is hooked, reminding one of the Hook-tip Moths. In the 

 males there is a large apical orange patch. This butterfly 

 is found throughout the southeastern part of the United 

 States, not including Florida. It occurs as far north as 

 New Haven, Conn. It is nowhere abundant. 



Synchloe olympia (Syn'chlo-e o-lym'pi-a). — In this species 

 the orange patch is wanting in both sexes. There is a con- 

 spicuous black bar at the end of the discal cell of the fore 

 wings, and the apical portion of these wings is gray, includ- 

 ing a large irregular white band (Fig. 463). 



This species occurs in the Mississippi Valley. 



III. The Yellows. — The Yellows are easily recognized by 

 their bright yellow colors, although in some species whitish 

 forms occur. They abound almost everywhere in open 

 fields, and are common about wet places in roads. To this 

 group belong the larger number of our Pierids. 



The Clouded Sulphur, Eurymus pliilodice (Eu'ry-mus phi- 

 lod'i-ce). — The wings above 

 are rather pale greenish yellow, 

 with the outer borders black- 

 ish brown. Figure 464 repre- 

 sents the male ; in the female 

 the border on the fore wings 

 is broader, and contains a sub- 

 marginal row of yellow spots. 

 The discal dot of the fore 

 wings is black, that of the 

 hind wings is orange. The under surface is sulphur-yellow. 



This species is dimorphic. The second form is repre- 

 sented only by the female sex, and differs in having the 

 ground-color of the wings white instead of yellow. 



The Clouded Sulphur occurs from the mouth of the St. 

 Lawrence to South Carolina and westward to the Rocky 

 Mountains. Its larva feeds upon clover and other Legu- 

 minosae.
