66 ENTOMOLOGICAL SOCIETY 



The following table may assist in separating the species of 

 Hemiceras at present described. H. obliquicola Walker, H. 

 pulverula Guenee, H. buckleyi Druce, and H. egregia Dognin 

 are not included, as there exist no figures and the several 

 descriptions are not sufficiently detailed to enable me to place 

 the species in the table. The species not referred to in Mr. 

 Schaus's revision of the Notodontidae were published in the 

 Transactions of the American Entomological Society, Volume 

 XXX, pp. 147-148, 1904. 



Epicoria gemina Walker is referred to Hemiceras by Mr. 

 Schaus ; but as Walker states that the male antennae are setose, 

 it would seem better placed in another genus. I have no speci- 

 men certainly identified.
