Lepidoptera of Xew York axd Neighboring States 527 



on veins, the uppermost 1 mm. before the apex; those on CUj, Cu 2 , and A obscure; 

 sub-basal, antemedial. and postmedial black dots in fold, the latter well beyond 

 the series on the veins; and black terminal points. 55 mm. 

 Southern States in June. 



2. S. sordidellus Zincken. Male with blunt squarish wings; dull fuscous; fore 

 wing with black discal and terminal dots; a postmedial series from just before 

 apex to three-fourths way out on inner margin; obscure below. Hind wing con- 

 colorous, slightly paler at base. 30—25 mm. 



Uncus pointed; gnathos emarginate; bearing a spine nearly as long as the 

 uncus; transatilla with rudimentarv free lobes; juxta with a short, pointed ven- 

 tral spine. (Fig. 301). 



Female with narrow, lanceolate wings, the postmedial series reaching inner 

 margin three -fifths way out. normally obscure, or replaced by an obscure dark 

 line, irregular below. Fore wing with ground sometimes heavily dusted on an 

 ochreous base. Hind wing white, _ shaded with gray toward margin. 35-48 mm. 



August; June in the South. 



Southern States; Illinois, Woods Hole. Massachusetts (dwarf). 



3. S. nitidellus Dyar. Male superficially like that of 8. sordidellus, but smaller; 

 fore wing striate in two shades of fuscous; practically immaculate otherwise. 

 25-30 mm. Gnathos not emarginate, running into a short broad spine, half as 

 long as the uncus; transatilla with two heavy backward-directed hooks, juxta 

 with a large blunt spine swollen at the tip. (Fig. 302). 



Female rather larger than male with narrow lanceolate wings, fuscous, or, 

 rarely, clay-color, dusted with fuscous; with a blackish shade from base to apex. 

 Postmedial' line represented by an obscure shade, and a more distinct dot in the 

 fold. Terminal dots weak. 35 mm. (dispersellus Robinson in part?). 



Hampton, Xew Hampshire, to Texas. 



S. clemensellus Robinson is unknown to me; as described, it must be closely 

 similar to the preceding species, but perhaps with more distinct pale streaks on 

 the veins. (Size and locality not given). 



S. roscidellus Dyar, from the Gulf Strip, is also blackish with pale yellow veins, 

 but the hind wing is almost wholly white. If I have it correctly determined the 

 uncus is blunt, the spine on the gnathos almost as long as the uncus and well 

 set off, the hook on the transatilla strong, and the spine on the juxta even in 

 width for most of its length. 



4. S. unipunctellus Robinson. Unicolorous dark fuscous, with a conspicuous 

 black discal dot. Uncus shorter than spine of gnathos, which is even in width 

 and arises from a deep notch in the gnathos. Spine of juxta very, large and 

 pointed; transatilla with a pair of large rounded lobes notched at the apex. 

 The female appears to be dimorphic, as both fuscous and straw-yellow females 

 have been taken with males of this appearance. (Fig. 303). Male 20 mm., 

 female 25 mm. 



Southern States. 



5. tripunctellus Robinson. Powdery fuscous on a cream-colored base, show ■ 

 ing two distinct blackish dots in the fold as well as the discal dot. Uncus short, 

 blunt, and very broad; gnathos deeply emarginate, with a short tapering spine; 

 transatilla bearing very large hooks, and spine of juxta swollen toward the tip. 

 Female straw yellow, apparently indistinguishable from the yellow form of 

 X. innpunctellus. 20—25 mm. 



Southern States. 



5. S. melinellus Clemens. Male straw yellow, with a faint grayish postmedial 

 line extending down from apex, and fading out below : slightly narrower winged 

 than 8. longirostrellus, but not constantly distinguishable on superficial characters. 

 A discal black dot and two dots in fold. Genitalia similar to those of S. tripunc- 

 tellus, but uncus narrower toward the base, spine of gnathos stouter, hooks of 

 transatilla hardly as large, and spine of juxta more swollen at the tip. (Fig. 304).
