are situated in the outer (third) line. Subapical hollow deep; fringe elsewhere 

 eoneolorous with the wings, in the excavation dusky, with a deep-brown hue 

 ,11 base. Hind wings eoneolorous with the anterior pair, with two transverse 

 lines, the outer double and with brown venular dots; the lines vary much in 

 width and distinctness. A distinct diseal dot ; none on the fore wings. A 

 marginal line of brown dots on both wings. Beneath, pale ochreous-while, 

 with scattered dark specks. Two common lines, the inner distinctly waved, 

 the outer narrower, bent on the eosta on the fore wings, and opposite the 

 diseal dot on the hind wings, and accompanied by a broad, irregular, ochreous 

 shade, sometimes consisting of isolated patches; fringe and marginal line as 

 on the upper side. The diseal dots are large, dark, and very distinct. Legs 

 pale, spotted with ochreous.

This pretty species, with much of the form of »S'. bisignata, may be dis- 

 tinguished from all our other forms by the large brown spots in the middle 

 of the outer third of the wing, subdivided by the pale venules into five or six 

 spots. It varies a good deal in its markings. The Texan example is browner 

 than in northern examples. I was unable to distinguish the specimen I took 

 for comparison from M. Guenee's M. enotata from Northern Brazil, Amazon, 

 and Surinam, not finding any specific differences, and shall conclude, until 

 more material comes in from South America, that the present species is 

 among the few Lepidoptera which range from Brazil to Maine. This is also so 

 close to Walker's example of S. enota'a from Santarem (Bates) that I should 

 not venture, to separate it. It is very closely allied to the European Semiotkisa 

 notata. I have examined Mr. Morrison's type, and also Professor Zeller's.
