42 INSECUTOR INSCiTI/t MENSTRUUS 



I have associated with this three specimens, in general similar. One, 

 La Florida, Costa Rica, March, 1907 (W. Schaus), has the hind wing 

 darker, the disk closely reticulated and not appearing conspicuously 

 lighter. The second, Cordoba, Mexico, May, 1 9 1 (L. O. Howard), 

 has the hind wing still darker, the reticulations forming a solid shade with 

 punctiform spaces, tlie pale ray from discal spot to inner margin nanow 

 and contrasted. The third specimen is from Peru (Schaus collection) 

 and is large, the hind wing especially strongly shaded with coppery red, 

 the costa not contrastingly dark ; discal spots rather large. 



Dysodia thyridina Felder & Rogenhofer. 



Dysodia thyridina Felder & Rogenhofer, Reise Novara, Lep., pi. 117, f. 20, 



1873. 

 Dysodia thyridina Warren, Nov. Zool., xv, 334, 1908. 



Described from French Guiana. The figure is very similar to D. angu- 

 lisola, described above, and may be the same, but the apical dark mark 

 is shown attached to the margin, which does not occur in angulisola. 

 Hampson referred this as a synonym of speculifera, but I cannot so con- 

 sider it. Warren also separates it, but I cannot decide from his remarks 

 whether this is the same as angulisola or not. 



Dysodia speculifera Sepp. 



Phalaena speculifera Sepp, Surin. Vlind., iii, pi. 135, 1830. 



Varnia aequalis Walker, Cat. Brit. Mus., Lep. Het., xxxiii, 825, 1865. 



Specimens are before me from French Guiema and Venezuela. 

 Walker's aequalis was described from the United States, presumably 

 Florida. I have seen no specimens from our territory. Sepp figures the 

 larva in a rolled, partly cut off leaf, but he does not mention the name of 

 the food plant. He says: "Cette retraite est composee d'une feuille 

 liee etroitement et dont le bout est decoupe a demi pour former une 

 ouverture, servant d'issue aux excrements. EUe quitte cette demeure 

 pour chercher sa nourriture, et apres avoir satisfait ce besoin elle s*y retire 

 pour se reposer." 



Dysodia pyrsocoma, new species. 



A development of speculifera wath the bands broadened, the wings 

 narrowed and suffused with fiery red. It is probably a form of confusata 

 Warren, near to olivescens Warren, but bright red instead of brown. I 

 list it as a species, as I have not seen Warren's two forms and may pos- 

 sibly have misinterpreted the descriptions.
