A New Deltoid. 



By A. R. Grote. 

 Megachyta gypsalis, n. & 



q 7 ^. Male antennre ciliate, bristled, and with a median scaled 

 notch on flexure. Size of liturali* and Zeller's (leceptricali*, with den- 

 tate outer median line like the latter, while differing from both in 

 color and detail of markings, while much nearer to deceptricaJis. 

 Chalky white, the base of primaries shaded with ochery, the termi- 

 nal and s. t. spaces sprinkled with brownish black. Inner line with 

 but a moderate costal thickening, forming three lobes. Outer line 

 with the costal portion only moderately thickened but much curved 

 an 1 outwardly projected, denticulate to internal margin. A straight 

 denticulate s. t. line, the dark terminal space cut by the pale veins. 

 The s. t. line white, bordered outwardly by black. Hind wings whit- 

 ish with double fuscous lines ; the black terminal line sub-continu- 

 ous. Beneath with dots and well-marked fuscous median lines. The 

 greater projection of the line, as compared with deceptricalis, shows 

 also beneath. 



Expanse, 22 mil. North Carolina, Mr. Morrison. 



The costal spots are much reduced in this, the third described 

 species of the genus.
