THREE SPECIES OF MOTHS NEW TO OUR FAUNA. 



BY HENRY EDWARDS, NEW YORK. 



After all, the geographical range of our fauna, as regards the distribu- 

 tion of insects, is but incompletely marked, and the fact that artificial 

 lines cannot limit the habitat of a species is every day made more appar- 

 ent. The Florida coast is constantly turning up species properly belong- 

 ing to the fauna of the West Indies, and Texas and Arizona are as often 

 adding Mexican forms to our list. It is, nevertheless, somewhat strange 

 that three such conspicuous species as those hereafter noted should have 

 only recently appeared within our limits, or at least for so long a time 

 have escaped the watchful eyes of our numerous observers. They may 

 all be cited as examples of the Mexican fauna, though Psendosphinx 

 Tetrio is also found in the W. Indies, and on the continent reaches as far 

 south as the Argentine Confederation. As the insects are probably not 

 known to our local collectors, I have thought it advisable to append 

 descriptions of each. 



FAM. SPHINGIDjE. 



Pseudosphinx Tetrio, Linn. 



Whole upper surface light gray, the lines and markings brownish black, 

 The basal half line is whitish, with a black dash behind it obliquely. 

 Between it and the median line are some waved brownish indistinct 

 streaks, reaching only from the costa to the middle of the wing. There 

 is a very prominently marked discal spot, and a sub-triangular brown
