in nature, and Eduardsia has been only superficially viewed. Psyclio- 

 morpha I have had no specimens of that I could denude, but it seems close 

 to Alypia. 



No exotic material has been compared except as above stated, because 

 it was not intended to do more than separate into compact, easily definable 

 groups that composite mass termed in our lists Zygaenidae. 



To resume, my arrangement of the genera here discussed would be 

 provisionally as follows : 

 Zygaenidae not represented. 

 Syntomoidae Didasys Grt., Cosmosoma Hb., Syntomeida Harr., 



Anatolmis Pack., Lycomorpha Harr., Horama Hb. (?), Laemocharis 



H. S. (?) 

 Pyromorphidae Pyromorpha H. S., Harrisina Pack., TriprocrisQvt. 

 Ctenuchidae Ctenucha Kirby, Scepsis Walk. 

 Alypiidae Alypia Hb., Pseudalypia Hy. Edw. (?), Edwardsia Neum. 



(i*), Ps^ychomorpha Harr. 

 Eudryas and allies find a place in the Bomhycidae.
