UNIDENTIFIED BOMBYCIDS. 



Sir: Concerning Prof. Smith's note on page 164 of June Can. Ent., 

 it is, perhaps, unprofitable to enter into a discussion as to whether the 

 generic names from Hubner's Tentamen should be adopted or not ; but, 

 as far as our Bombyces are concerned, there are only four of these names 

 with which we have to do. They are : (1) Nycteola, Hubn., for Sarrothripus, 

 Curt.; (2) Hypercompa, Hubn., for Zoote, Hubn. (Verz.), for Euprepia 

 caja, Linn.; (3) Dasychira, Hubn., for Dasychira, Steph.; (4) Melalopha, 

 Hubn., for Ichthyura, Hubn., (Verz.). The third of these introduces 

 only a change in the name of the author ; Euprepia cannot stand for caja 

 anyway, since it must be used for the species of " Arctia " according to 

 Mr. Kirby's method of fixing types, which seems eminently proper. The 

 name Arctia., Schrank, has for its type A. villica, Linn., replacing Epi- 

 callia, Hubn. Our species, E. virginalis, by the way, is not congeneric 

 with A. villica, nor with C. dominula, as Kirby puts it ; but it seems 

 hazardous to change it till the European genera have been revised. If 

 we discard Hypercompa (Hubn., Tent ), for caja, the name Zoote (Hubn., 

 Verz.), comes next in order. Thus there are only two of the Tentamen 

 names which supplant names now in use, and only one which supplants a 

 name by a different author. It seems to us more satisfactory to adopt these 

 names and end controversy about them, especially as they have been 

 adopted by Kirby in his work where the Bombyces of the world are brought 

 together in a uniform system. We dislike to depart from this standard 

 without conclusive reason. Harrison G. Dyar. 



AGASSIZ ASSOCIATION. 

 Sir, — The Henry Edwards Entomological Corresponding Chapter of 

 the Agassiz Association invites entomological students who read this 

 notice to join its ranks. Members are expected to keep each other in- 

 formed of the progress of their work in special lines of study, and to 

 contribute to the published reports. During the winter one or more 

 courses in Elementary Entomology will be conducted. The initiation fee 

 is 50 cents. For further particulars, address the Secretary,
