1542 THE BUTTERFLIES OF NEW ENGLAND. 



closely allied H. syrichtus was noticed by nie in Cuba as living not very 

 swiftly scarcely a few inches above the ground, and with less of the skip- 

 ping movement than is common among the Hesperidae. When it alights 

 in the sun, it expands the wings completely ; when it first alights, the cos- 

 tal edges of the fore wings form a common straight line or they may be 

 slightly advanced : when at more perfect rest, the fore wings ne;u-ly cover 

 the hind pair, so that the costal margins of tiie former make an angle of 

 about 135° with each other ; the antennae then droop at an angle of about 

 45° with the body and spread at an angle of about 150°. 



Desiderata. No facts concerning the distribution of this insect in the Al- 

 leghanian fauna, or west of the great plains, can fail of adding to our very 

 meagre knowledge of the distribution of this butterfly. But what we most 

 need are more details concerning the structure and markings of the insect 

 in its early stages, for the egg and the earlier larval stages are almost en- 

 tirely unknown, and the chrysalis imperfectly described. So, too, no one 

 has attempted to trace its life history, and the sketch given here is only 

 made up from scattered notes of captui'C : not a line has been written of 

 the larval habits nor much of those of the butterfly. And yet in the 

 south it is one of the commonest species and can be easily reared. We do 

 not even know how the winter is passed, judging that it is in the chrysalis 

 only by the analogy of its congenei's which are said to do so.

There is a sleep for all things. On still nights 



There is a folding of a million wings— 

 The purple honey-bees in unknown woods, 

 The speckled butterflies, and downy broods 



In dizzy poplar bci^'bts: 

 Sleep for innuiiirral>li- nameless things, 

 Sleep for the creatures underneath the sea, 

 And in the Earth, and in the starry Air I . . .
