between the two species are too marked to leave any doubt of their being 

 distinct. Mr. Hermann Strecker informs me that he has never heard of P. 

 cecropia being taken west of the Mississippi River. The example of 

 Anthocharis ausonides differs somewhat from my specimen of that species 

 from California, and resembles more the European Anthocharis belia.

Dear Sir, — 



In reply to the synonyms selected by Mr. Morrison (on page 79 of 

 this volume), from my frequent papers during the last thirteen years, I 

 wish to state that Orthosia ferrugineoides Grote ex. Guen. is a different 

 species from Orthosia ralla Grote ex. G. & R. ; the latter differs by the 

 pellucid yellowish hind wings, not clouded with fuscous, and the black 

 dots of the subterminal line, among other characters. Plusia on is twice 

 the size of P. fratella, and I have seen no intermediate specimens. It is 

 not right to express oneself in such a manner, that my synonyms in the 

 Noctuidae, occurring from time to time during the description of over four 

 hundred new species (in the face of the difficulties imposed upon students 

 by the works of Guenee and Walker) over a long period of time, appear 

 to be charged as committed within six months. Of the six synonyms I 

 am charged with, one is an error of Mr. Morrison's, and only two were 

 published in 1874 ; the remaining three species were published and figured 

 by me in 1863, 1864 and 1870 respectively. I also have shown Tricopis 

 and Euleucyptera to be distinct, and I take issue with Mr. Morrison as to 

 the validity of Bol'uia nigrescens as distinct from faseiolaris, and on the 

 authority of my catalogue names. 



Mr. Morrison remarks (p. 79) that " in ignoring (?) Mr. Grote's genera 

 Eueoptoenemis, Exyra and others (?) I simply follow the example of Dr. 

 Speyer,'' etc. Now, the fact is, that on the only occasion which Dr. 

 Speyer has yet had to refer to one of these genera of mine, it is adopted, 

 not ignored (vide Leucobrephos Speyer, Stett. Ent. Zeit., 1875, 175). There 

 are, however, only three such names in my whole List, viz., Conservula. 

 Exyra and Leueobrephos. The diagnosis of TricJwlita is given by Mr. 

 Morrison under the term " Perigrap/ia," which applies to a different 

 form ; Eucoptocnemis is distinctly and properly founded on structural 

 characters given by Guenee to the single species : fimbriaris. The other 

 generic names of mine without diagnosis in the " List" replace, for one 

 sufficient reason or another, a name previously used.
