NEW SPECIES OF NORTH AMERICAN LEPIDOPTERA. 



BY WILLIAM BARNES, S. B., M. D., DECATUR, ILL. 



(Continued from page 173.) 



Mamestra elsinora, n. sp. — Expanse : 37 mm. 



General colour very dark blackish brown, with a slight purplish tinge, 



quite smooth and somewhat shiny. Ordinary markings jet black, but not 



conspicuous, owing to the similarity in shade with the ground colour. 



The distinct black, more or less solidly filled claviform and the yellow- 

 filled reniform are the most conspicuous features in the maculation. 

 Basal line present though fragmentary, represented by two blackish dots 

 on costa, in one specimen with some whitish scales between them, 

 forming a more or less evident dot, in the other specimen this is not so 

 noticeable, the line is also evident between the median and submediaii 

 veins, though in a lighter, diffused sort of way. Just above the median 

 vein is a small yellow point, quite distinct in one specimen, faint in the 

 other. T. a. line transverse, more or less outwardly scalloped between 

 veins, in a few places, especially on the costa, showing as a double line, 

 with a somewhat paler filling. The outer line is the more easily traced, 

 but even this is not very distinct without a lens. A narrow median shade 

 can be made out running from costa downward and outward to lower 

 edge of reniform, thence to inner margin very close to termination of t. a. 

 line. T. p. line only moderately exserted over cell, thence parallel to outer 

 margin in a quite direct line to inner margin, inwardly scalloped between 

 veins. An outer accompanying line is only indicated here and there by a 

 few scales and a tendency to a lighter filling between the two is evident 

 though very faintly marked. S. t. line fragmentary, wavy, showing a 

 mixture of black and yellow scales, with the naked eye the yellow can be 

 traced as a faint fragmentary line across the wing and the black as two 

 closely approximate sagittal dashes opposite cell, extending almost to 

 reniform and usually one smaller one just below costa. With the lens 

 these sagittal marks can be traced more or less plainly across the wing, 

 and the yellow scales seem to be imbedded in them. There are fine 

 yellow points at the termination of veins, which have a tendency to 

 extend outward, more or less completely through fringe, giving it a faintly 

 checkered appearance. Fringe concolorous, with a very faint, wavy, 

 lighter mesial line. Orbicular moderate in size, narrowly black ringed, 

 within which the lens shows indications of a fine yellowish line.
