AMERICAN LEPIDOPTERA. 307 



EPIZEUXIS, Hubner. 



This generic term has priority over Helia, Guenee, and should be 

 retained for our species of which I recognize, with certainty, two in 

 the collection before me from the Atlantic District. 



Mr, Walker's Microphysa ? scriptipennis is a re-description of 

 Helia americalis, Guenee. The Microphysa ? mollifera of the British 

 Museum Lists is also founded on a species of Epizeuxis, but my notes 

 do not indicate the particular species; I think that E. aemulalis is 

 thus re-described. To Mr. Walker is due the credit of having recog- 

 nized Hubner's priority for the generic designation. 



Epizeuxis aemulalis, Hiibner.— % 9 .—Very variable in size and depth 

 of color. Of a rather dark bluish testaceous grey. Transverse line narrow 

 rivulous, black, continued. Reniform yellowish, with a faint interior blackish 

 line, approximate to the diffuse black median shade. Orbicular minute, ap- 

 proximate to the t. a. line, pale. T. p. line succeeded on costa by a pale shade 

 very irregularly and finely dentate. Subterminal line faint, atomical, pale 

 with darker inner edging. A fine very black interrupted terminal line. 

 Secondaries a little paler with three approximate transverse rivulous darker 

 lines, the median usually most distinct, the outer sometimes very distinct, 

 generally fainter than the others. Beneath with double, finely dentate 

 transverse common lines, and two divaricate black discal marks on either 

 wing. Expanse 25 to 30 m. m. 



Habitat. — New York to Virginia. 



Epizeuxis aemulalis is a very variable species in size and color, so 

 that I do not feel authorized to describe as distinct a pale specimen in 

 the collection which differs from all the rest in that the discal spots of 

 the fore wings above are diffusely black. 



Epizeuxis ameriealis, Walker. 

 Ilelia americalis, Guenee. 



% 9- — This brightest and most distinctly marked species of the genus resem- 

 bles the European E. calvarialis, and seems to represent it in our fauna. It is 

 paler, shorter winged and more distinctly lined, especially on hind wings 

 The transverse lines on the primaries differ in detail in the two species. In 

 ours they are more rivulous or dentate, as in E. aemulalis. The median shade 

 in americalis is less diffuse and differently situated, since it runs approximate 

 to the reniform and joins the costa just within the inception of the t. p. line, 

 whereas in calvarialis it crosses the median space centrally. Our species 

 varies in size, but very slightly in ornamentation or color. Expanse 20 to 

 26 m. m. 



Habitat. — Massachusetts to Georgia. The larva has been reported 

 to me to occur commonly on Indian corn; Abbot figures it on an un- 

 published plate on phlox.
