Genus Lycaena 



(/) Southern form piasus, Plate XXXI, Fig. 10, $. This 

 form, which is uniformly darker blue on the upper side than the 

 others, is found in Arizona. 



There are still other forms which have been named and 

 described. 



Early Stages. These have been traced through all stages with 

 minutest care. The egg is delineated in this book on p. 4, Fig. 7. 

 The caterpillar is slug-shaped, and feeds on the tender leaves and 

 petals of a great variety of plants. 



The range of the species is immense. It extends from Alaska 

 to Florida, and from Anticosti to Arizona.

Butterfly. Closely resembling L. comyntas, of which it may 

 be only a slightly modified Western form. Until the test of 

 breeding has been applied we cannot be sure of this. The fig- 

 ures in the plate give a very good representation of the upper 

 side of the wings of this species. 



Early Stages. But little has been found out concerning these. 

 It ranges from the eastern foot-hills of the Rocky Mountains to 

 the Pacific in British America and the northern tier of Western States.

Butterfly. The blue of the upper side of the 

 male in the plate is too dark; but the female and 

 the under side of the wings are accurately deline- 

 ated. The species is generally tailed, but speci- 

 Neuration 37 of mens without tails occur. Expanse, i.oo-i. 10 inch. 

 Lyccena comyn- Early Stages. These are well known and have 

 Typical" of g fhe ^ een ^ U ^Y described. The caterpillar feeds on legu- 

 subgenus Ev- minous plants. 



This delicate little species ranges from the val- 

 ley of the Saskatchewan to Costa Rica, and from the Atlantic to 

 the foot-hills of the Western Cordilleras. It is common in the 

 Middle and Western States, flitting about roadsides and weedy 

 forest paths.
