running closely parallel to outer margin, to anal angle. Two parallel lines 

 trisect the space between the subterminal line and the apex, but fade out below, 

 leaving a narrow continuous white margin. Terminal line fine, black at costa 

 only, faintly continued to the notch. A yellow marginal shade below the 

 notch, containing three black dots, in cells M3, Cuj, Cuo, the middle spot 

 notably weaker than the other two. Fringe white above notch, with a faint 

 yellow tint, lead-gray below, but shading into white again at anal angle. Hind 

 wing yellowish white, with pure white fringe. Under side of fore wing dirty 

 yellowish white with the three black marginal dots larger but less intense ; 

 hind wing white. 11 mm. Two males, Schriever, La., June 17, 1917, taken at 

 light at edge of woods. Cornell U. type and paratype number 464. 



In Fernald's key this species will run to C. pusionelhis, but it is 

 much smaller, there is a distinct black spot on the middle of the wing, 

 and the st. line is single except toward the costa, and much nearer 

 the outer margin. From C. albellns it differs in wing-form, in having 

 only three marginal dots above and below instead of five, in the two 

 median black dots, and the white hind wings. 



Crambus immunellus ZelL, new race minor. 



Our specimens are evidently varietally distinct from Zeller's South Amer- 

 ican C. immunellus (Stett. Ent. Zeit., 1872, PI. 2, {. 6; Horae Soc. Ent. Ross., 

 13, 47, 1877), but seem more closely related to it than to the northern C. 

 elegans. This form is smaller than elegans or immunellus, the ground largely 

 whitish with a rather distinct blackish shade along the costa, which is cut by 

 the strong oblique white median and subterminal bars, but extends well beyond 

 the latter. The blackish marking on the inner margin is smaller than in 

 elegans and tends to be divided on A, but is black rather than brownish. The 

 submarginal line is suffused except at the costa, with only traces of a pale 

 center-line, and tends to be a little dentate, especially on its inner border. 

 It turns sharply away from the outer margin toward the costa and meets the 

 costa barely four fifths way out. The terminal dots are much heavier than 

 in C. elegans, the first two being elongate and almost running together. The 

 hind wing and under side appear paler than in elegans, and the labial palpi 

 are white with heavy blackish bars covering half the surface of the second 

 and third joints, instead of the solidly darker outer face of elegans. From 

 typical immunellus the form may be distinguished by the suffused, mostly dark 

 submarginal line, the smaller size, and probably more intensely black dorsal 

 crescent; from C. polingi by the small size and separate terminal dots. 10 

 to 12 mm. Two males, both at light. Type Biloxi, Miss., June 13, 1917; 

 paratype Schriever, La., June 17, 191 7, Cornell U. number 465.
