basal third an improminent dark dot, a similar more prominent dot on the middle at 

 the end of the disk, and a third below it, near internal margin. Terminal dots dark 

 fuscous, minute. Posterior wings, fringes and undersiirface of both pairs glossy 

 white. Abdomen and anal tuft white. Expanse 22 mm. Habitat, Texas." 



Robinson wrote the above description from three females in very- 

 poor condition. I now have three males from Texas before me with 

 the tyj)es and would add that fresh specimens have terminal dots on all 

 the wings, a dot on the fold near the base, another on the outer third 

 of the median vein and an oblique stripe from near the apex down to 

 the hind margin through the outer dot on the fold, all of a dark brown 

 color. 



S. melinellus, Clem. 



This species was described by Clemens in the Proceedings of the 

 Academy of Natural Science of Philadelphia for the year i860, p. 205. 

 The following is his brief diagnosis ; 



"Ochreous yellow. Fore wings with a pale fuscous streak along the middle of 

 the fold, extended nearly to the tip, and a faint oblique line of the same hue, from the 

 tip, not extended to the hind margin. Hind wings pale yellowish white. Abdomen 

 tufted." 



The type of this species is not in existence and was probably de- 

 stroyed before the Clemens collection was given to the Am. Ent. Soc. 

 Dr. Clemens does not say whether there are terminal dots or not. It 

 may ha\e had them, since in the same paper he described 6". longirostrel- 

 lus which has terminal dots and he did not mention them. His type 

 was undoubtedly a female since he mentiones the abdominal tuft. 



Robinson in his paper in the Annals of the Lyceum of Natural 

 History of N. Y., Vol. IX, 1870, described what he believed to be 

 melinellus as follows : "Palpi, head and thorax ochreous, the palpi pale 

 internally. Anterior wings varying from pale to dark ochreous, shaded 

 more or less prominently with fuscous above the middle from the base 

 to the apex. A dark fuscous dot, sometimes obsolete, at the end of the 

 cell, and a more or less prominent oblique streak from the apex to the 

 middle of the wing. There are no terminal dark dots before the ochreous 

 fringes. Posterior wings and fringes white or pale yellowish white. 

 Expanse, 9 24 to 28 mm. Habitat, Penn., N. Y. This species agrees 

 most nearly of any in my collection with Dr. Clemens' brief description. " 



I have before me Robinson's two examples from which he wrote 

 the above description and also eight other examples from Mass. and 

 London, Ontario. Robinson lays stress on the absence of terminal 

 points in this species, but in some of the specimens before me there are 

 faint indications of terminal points, and in fact this species grades so 

 imperceptably into dispersellus that I am not able to separate them. It 

 is impossible to say which of these forms Clemens made his description
