FAMILY IX 



THE METAL-MARKS 

 Family Riodinidae (Ri-o-din'i-dae) 



The metal-marks are small butterflies, which bear some 

 resemblance to the gossamer-winged butterflies and were 

 formerly classed with them. They 

 are distinguished from the gossamer- 

 winged butterflies by the presence 

 of a humeral vein in the hind wings, 

 and from them and all other butter- 

 flies by the presence of what appears 

 to be a well-preserved costa of the 

 hind wings. In some genera this 

 costal vein is free at the tip and 

 projects (Fig. 39). 



Only twelve species are found in 

 America, and nearly all of these are 

 from the far West or Southwest. The 

 two following species occur in the 

 East.
