AMERICAN LEPIDOPTERA. 83 



Hab. — United States and Canada east of the Kooky Mountains, 

 taken from May to Septembex' in the northern part of its range, 

 March and April in Texas and Florida. 



Walker cites in the synonymy Phytometra minuta Haw., Lep. 

 Britt., 265, with what justice I do not know. 



This species is by all odds the most common representative of the 

 genus as well as the most widely distributed. In the large series 

 before me little real variation occurs. The contrasts may be all 

 sharply defined, there may be a black shade in the darker part of 

 the wing, or everything may. run toward olivaceous or yellowish. 

 Yet the characteristic appearance of the species is not changed. 



The primaries are moderate in length, trigonate, the apices well 

 marked. In the secondaries vein 5 is weak, and from the cross-vein 

 well removed from the median. Veins 3 and 4 separate at varying 

 distances beyond the cell, averaging about one- third of the way to 

 outer margin.

 Size and appearance of candefacta, of which it is a near neighbor. Primaries 

 of a yellowish white, with a basal spot, a subterminal half line and the middle 

 below the cell leaden gray. The latter space traversed by undulated deeper lines 

 and surmounted by a yellow or olive tint that forms a band anteriorly, and cir- 

 cumscribes a semicircular costal space of the ground color, in which are two black 

 punctiform spots, of which the first is often the only one visible. At the apex 

 this shade is tinted with red-brown. Fringe white above, leaden inferiorly. Sec- 

 ondaries yellowish white, uniform, similar in both sexes. Beneath, primaries 

 tinged with reddish, the marks showing through. 



The above is a free translation of Guenee's description of South 

 American examples, and he remarks that he has not seen Georgian 

 specimens. 



I saw these examples at Paris and noted them as having the 

 maculation of candefacta, l)ut a darker color and narrower wings.
