THE CANADIAN ENTOMOLOGIST. 129 



Genus Habrosyne, Hiibner. 

 H. scripta, Gosse. 



Our single species is closely allied to the European H. derasa. Dr. 

 Ottolengui has distinguished a climatic variety in his collection, which is 

 of interest. The larva is known. 



Genus Pseudothyath-a, Grote. 

 Closely related to the preceding. The larva of one form is known, 

 and closely resembles that of Habrosyne. As I have not seen the proof 

 that the two forms classed here are but varieties, I would prefer to give 

 them specific rank. I have seen no intergrades. 

 P. cyniatophoroides, Grote. 



P. exptiltrix, Grote. 



Genus Ejithyatira, Smith. 



The larva of the only known species is widely different from that of 

 the European Thyatira batis. Our larva is a concealed feeder, and 

 without markings, while the European one possesses the structure of 

 Habrosyne, but still further developed. 



E. lorat'i, Grote. 



E. pudetis, Guenee. 



E. semicircularis, Grote. 



The structure of the veins excludes this last species from Bombycia; 

 its markings do not differ essentially from those of Etithyatira. though 

 the outer white patches are all lost, and the wings are rather broad. 



Genus Bombycia, Hiibner. 



Mr. Hampson, in his Moths of India, refers Bombycia to the 

 NoctuidcE, but this is the Bombycia of Stephens, not of Hiibner (type B. 

 viminalis. Fab.). According to Mr. Grote, the type of Bombycia, Hubn., 

 is B. or, of Europe. We have two species, or possibly varieties, con- 

 generic with this type. 

 B. improvisa, Hy. Edw. 

 B. tearlei, Hy. Edw. 



The larvie are unknown. 



The two species numbered 1,467 and 1,469, in Smith's list, have 

 been already removed from the family. Concerning No. i,46-],i)iagnijica, 

 Streck., Mr. Grote writes in the Entomologist's Record and Journal of 

 Variation (Vol. VI., p. 80) : — "Examined by me in 1882, and determined 

 then to be a Cossid." The reference of this species to Cossula by the 

 late Mr. Neumoegen and myself was quite independent of Mr. Grote's 

 observation, and it is interesting to have his positive determination thus 

 corroborate ours, made solely from the description. 



Bombycia Candida, Smith, will require further examination before it 

 can be accurately placed among the Thyatiridne.
