on the edges of the streams or flying back and forth in the sunshine 

 over the pools and brooks with the same hurrying direct flight as 

 the kite swallowtails. But on first acquaintance they look as they 

 flit about more like dragonflies than butterflies. 



SOME OTHER STRANGE SWALLOWTAILS 



In northern Australia and New Guinea there lives a butterfly 

 {Ev/pycits eressida, pi. 4, fig. 9) which, except that it is brownish 

 instead of white in color, suggests a parnassian. It is very common 

 in suitable localities and sometimes swarms about the flowers of the 

 Eibcalyptus. It is curious in having the female smaller than the 

 male. The flight is direct and rather feeble. The caterpillars feed 

 on Aristolochia. 



Somewhat similar are two other butterflies, one with tails and one 

 without, belonging to the genus Emn/ades. These live along the Rio 

 Parana and its tributaries in Paraguay and Argentina in southern 

 South America. 



STILL STRANGER SWALLOWTAILS 



From Nepal to Tenasserim and northward to central China there 

 lives a curious stout-bodied butterfly {Teinopalpus imperialis^ pi. 2, 

 figs. 3, 4) that is very widely different from all other swallowtails. 

 The male has one and the female two long tails on each hind wing. 

 The males have a very swift flight and usually keep high above the 

 ground, flying about high trees, in their actions as well as in their 

 form resembling large and powerful nymphalids much more than 

 they do swallowtails. The females are seldom caught. This butter- 

 fly is very local and there are several local races. It lives in moun- 

 tain forests usually at an altitude of between 6,000 and 10,000 feet. 



Very curious butterflies are the two species of Armandia, one, a 

 large and handsome insect {Armandia Udderdalei, pi. 5, fig. 14), 

 living in northwestern Burma and Bhutan and thence to western 

 China, the other {Armandia thaidina), smaller, occurring in Sze- 

 chuan. The smaller species {A. thaidina) has three tails, one very 

 long and spatulate, and two shorter ones between this and the anal 

 angle. The larger (A. Udderdalei, pi. 5, fig. 14) has still another tail 

 just in front of the longest one. These butterflies fly in summer, 

 sailing about with a slow and undulating flight like that of the 

 "ghost butterflies" {Hestia) high up among the tree tops, often 

 permitting themselves to be carried by the wind, so that they appear 

 more like falling leaves than they do like butterflies. 



From Amurland southward to Japan and westward to central 

 China live the three forms of the single species of the curious genus 

 Luehdorfta (pi. 7, figs. 24, 25). These are medium-sized butterflies
