This pretty species, with much of the form of jS. hisig7iatth may be dis- 

 tinguished from all our other t()rms I)y the large brown spots in tlic; middle 

 of the out(M- third of the wing, subdivided by tlii' pate venides into five or six 

 spots. It varies a good deal in its markings. The Texan example is l)rowner 

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

 for comi)arison from M. Guenee's M. evotata from Northern Brazil, Amazon, 

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

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

 among the few Lep/dopfe/a^wh'wh range from Brazil to Maine. This is also so 

 close to Walker's exam])le of S. enota'a from Santarem (Bates) (hat I should 

 not venture to separate if. It is very closely allied to the European Semiothisa 

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