312 MOTHS AND BUTTERFLIES. 



Tlie colors are black and yellow, tlie wings being frecj^uently edged 

 with a narrow line of pink. The rather vague and fanciful resem- 

 blance of the 3'ellow patch on the upper wing to an animal's head has 

 given the insect the common name of the dog"s-head butterfly. The 

 insect is yellow beneath, with spots as sliowii in the illustration. 



MegaiiosloiuM ciL-souia. L'lider sitie. 



The sexes differ little in coloring. This s})ecies is much more 

 abundant in the south and southwest tiian in the east and north. I 

 have never taken it in New England, Init found a good many 

 specimens near Iowa City, Iowa, in August. It is a good flyer, and 

 one is obliged to move rapidly and use the net skilfulh- to capture 

 many specimens. 



A very beautiful species of this genus, MegayioHtoma eurydlce, 

 a native of C/aliforiiia and tlie Pacific coast, displays in the male 

 insect bright pink and piuple iridescence almost dazzling to the 

 eye. 



The genus Goui'pfcri/x contains some large and very showy 

 l)utterflies. Tlie shape of the wings is peculiar, in that they are 

 angular and look as if trinnned with the scissors, the upper wings 

 having the itp[)er margin strongly bowed and ending in a l)lunt 

 })oint, while the lower pair have a decided point midway on the 

 outer margin. The veins of the wings are large and raised, and 

 from the under side the insect bears a striking leaf-like look. lUit 

 two of the large and handsome species of this genus are fotmd in 

 this country north of Mexico, and they must be regarded as strag- 

 glers from more tropical climes.
