(G. ver-mic-u-la'ta) occurs in Colorado ; it is represented 

 by Figure 385. G. hopf- 

 feri (G. hopf'fe-ri) is 

 found in California, in 

 the foot-hills of the Sierra 

 Nevadas. It has three 

 yellow spots near the mid-

 a transverse row of from

 the outer margin ; on the hind wings there are two spots near 

 the base and another pair between these and the apex of the

Family ARCTIID.-E (Arc-ti'i-dae). 

 The Tiger-moths, or Arctiids (Arc' ti-ids). 



The Arctiidas includes stout-bodied moths, with moder- 

 ately broad wings, which in the majority of cases are con- 

 spicuously striped or spotted, suggesting the popular name 

 Tiger-moths ; some of the species, however, are unspotted. 



A large proportion of 

 the species are exceed- 

 ingly beautiful ; this 

 renders the family a 

 favorite one with collec- 

 tors. As a rule, when 

 at rest, the wings are 

 folded roof-like upon 



the body. The moths 

 fly at night, and are at-

 to see on account of the long hairs with which the head is
