 Alypia wittfeldii Hy. Edw. Taken by Mrs. Slosson. 



NOCTUIDJE. 



Agrotis ypsilon Rott. Taken by Mrs. Slosson. 



Peridroma incivis Guen. Common in the lawns ; the larvae 

 bred both in 1890 and 1900. (See Can. Ent., XXVIII, 18, and 

 Proc. U. S. Nat. Mus., XXIII, 273.) 



Feltia malefida Sn. Taken by Mrs. Slosson. 



Mamestra laudabilis Guen. Two specimens captured. 



Oligia chalcedonia Hiibn. Several examples at light. 



Oligia nudicolora Guen. At light, about as common as the 

 preceding. 



Oligia trientiplaga Walk. A specimen at light. This is the 

 same as aduncula Feld., and was kindly named for me from a 

 Brazilian specimen by Sir G. F. Hampson. 



Lussa nigroguttata Grt. One example at light. 



Magusa dissidens Feld. Rather rare. This species is 

 wrongly placed in our lists among the Quadrifids ; it belongs 

 near Prodenia as placed by Moschler. The following is its 

 synonymy :
