Genus Tachyris 



with white, resembling the chrysalids of the genus Colias, but 

 somewhat more slender. The caterpillar feeds upon conifers. But 

 one species is known.

Butterfly. — The insect on the under side sometimes has the 

 outer margin of the secondaries marked with spots of bright pink- 

 ish-red, resembling in this style of coloration certain species of 

 the genus Delias of the Indo-Malayan fauna. 



Early Stages. — -These have been thoroughly described by Ed- 

 wards in his third volume. The caterpillar infests the pine-trees 

 and firs of the northern Pacific States. The larva lets itself down 

 by a silken thread, often a hundred feet in length, and pupates on 

 the ferns and shrubbery at the foot of the trees. It sometimes 

 works great damage to the pine woods. 



Genus TACHYRIS, Wallace 



" The virtuoso thus, at noon, 

 Broiling beneath a July sun, 

 The gilded butterfly pursues 

 O'er hedge and ditch, through gaps and mews; 

 And, after many a vain essay 

 To captivate the tempting prey, 

 Gives him at length the lucky pat, 

 And has him safe beneath his hat; 

 Then lifts it gently from the ground; 

 But, ah! 't is lost as soon as found. 

 Culprit his liberty regains, 

 Flits out of sight, and mocks his pains." 



Cowper. 



This genus, which includes about seventy species, may be 

 distinguished from all other genera belonging to the Pierince by the 

 two stiff brush-like clusters of hairs which are found in the male 

 sex attached to the abdominal clasps. All of the species belong- 

 ing to the genus are found in the Old World, with exception 

 of the species described in this book, which has a wide range 

 throughout the tropical and subtropical regions of the New 

 World. The peculiarities of neuration are well shown in the 

 accompanying cut, in which the hind wing has been somewhat 

 unduly magnified in proportion to the fore wing. 



Early Stages. — The life-history of our species has not been 

 thoroughly studied, but we have ascertained enough of the early
