angle of this diamond gives off 6, ihe tip of cell 7 and derivatives, the 

 upper angle gives off 10. In a specimen in which the angle of the dia- 

 mond is more near the middle, vein 10 while still arising from the upper 

 angle, will also arise from the middle. To make so much of so little 

 illustrates the character of Mr. Grote's entire criticism. Finally Mr. Grote 

 utterly fails to state that in most, if not all the ArctiidiC with accessory 

 cell the neuraiion is practically the same as in the Noctuidce, except in 

 one imporiant particular, for while in the Noctuidce the dorsal or internal 

 vein is forked at base, in the Arciiidce and Lithosiida; it is simple. Now 

 of these two really family characters, viz: character of dorsal vein of 

 primaries and origin of subcostal of secondaries which make this genus 

 distinctively ^rc/eii/ Mr. Grote says absolutely nothing, while "from 

 memory " he allies it in venation to Grotella et al, with which it has not 

 even a habital resemblance. 



The characters of head structure and tibial armature are Noctuiform 

 as Mr. Grote says, and when I first called attention to this insect as a 

 new Arctiid, before the Entomological Society Washington, Prof. Riley 

 at once challenged the location on these grounds. I proved to his and 

 my own satisfaction that this structure was not controlling, and he at 

 once agreed that I was probably correct. 1 cite this as showing that the 

 point was not overlooked. The tibial armature is not unique — several 

 of the /irc/2V(5? genera, including Ocnogyna hdiWQ z. similar armature — nor 

 indeed is the clypeal structure, for Cydosia has almost identically the 

 same — a point probably unknown to Mr. Grote. 



1 have gone fully into tliib matter in a paper presented 8-10 months 

 ago tor publication in the U. S. National Museu»i, but not yet reached. 

 Wherever Cerathosia goes there must Cydosia g^ also. 



I have replied thus at length to Mr. Grote's remarks because they 

 were so utterly absurd that their very baselessness might challenge belief. 

 Also to prove that "memory", is a bad staff to rely on in scientific work, 

 and especially when it is in the form of criticism of another's work.
