The marginal baud on the anterior wings is not dentate between the 

 veins as in »S'. th^sbe Fab., from which the present is amply distinct by 

 its smaller size, differently colored legs and free discal cell, while we 

 have above discussed its structural position as forming a Group in the 

 present genus. 



This species is evidently the S. rujicaudis of Mr. Walker, judging 

 by the description in the British Museum Lists. It can in no event 

 be reo-arded as a variety of *S^. thiyshe, while we call the attention of 

 Lepidopterists to the formation of the inner margin of the outer band 

 on the anterior wings as affording specific character, in separating the 

 species of this genus. In IT. tlujshc it is very dentate inwardly on the 

 interspaces. 



Haemorrhagia raficaudis, Kirby. sp. non alior. 



The description of this species given by Kirby, reads as follows : — 

 •' Body yellow-olive, underneath pale yellow. Antennas black ; prima- 

 ries reddish-brown, hyaline in the disk, with the hyaline part half di- 

 vided towards the base, with a costal bar, covered with yellow olive 

 hairs at the base; underneath the costa, the posterior margin and the 

 nervures are dark ferruginous ; there is also a yellow stripe on the in- 

 ner side of the base; secondaries hyaline in the disk; base externally 

 and costa yellow; internally the base is ferruginous ; underneath the 

 dark part of the wing is ferruginous, and the base pale-yellow : two 

 first segments of the body yellow-olive, two next black, the rest ferru- 

 ginous with pale yellow lateral spots. This species appears to be the 

 American representative of Scuia fudformls which it greatly resembles, 

 but differs in the color of the tail and the base of the secondaries." 



Wer; we satisfied as to the species Kirby intended by S. facifor- 

 mu, the present species might be regarded as related to S. (liffintu 

 Boisd. sp. As it is, we think that a species of Hxmorrhagia is meant, 

 while the species has not been since identified. Kirby 's descri])tion 

 presents too many points of difference with //. /jraci/is, to allow us 

 to refer that species as intended, while Mr. Walker evidently describes 

 our species as intended by Kirby. Dr. Clemens is autoptically ac- 

 quainted with neither species while, properly keeping Mr. Walker's and 

 Kirby's descriptions apart. In dismissing the present genus from con- 

 sideration, we remark that the Asiatic .S'. radidim Walk., may belong
