[107] NORTH AMERICAN COLEOPTERA. 263 



tails concerning the locality and other circumstances have 

 been sent to the Entomological Society of Washington. 



IX. 



The statement of Dr. Horn (Proc. Ent. Sec. A. N. S. 

 Phil. ; June, 1886, p. xiii) concerning the identity of 

 Platycerus Agassii Lee. and califomicus Cas. is erroneous. 

 These two species are mutually more dissimilar in outline, 

 punctuation and general appearance than even oregonensis 

 and depressus. Before describing califomicus I had access 

 to a very fine series of ten specimens of Agassii in the cab- 

 inet of Mr. C. Fuchs, a specialist in this family, who had 

 previously written a synopsis of the American species 

 (Bull. Bk. Ent. Soc. V., p. 57). The specimens of this 

 series agree perfectly with Mr. Fuchs' description of the 

 type of Agassii, and also with the description recently given 

 by Mr. F. Blanchard (Tr. Am. Ent. Soc, XII. p. 169). 



Such absolute and unqualified assertions as the one re- 

 ferred to on the part of Dr. Horn, unaccompanied by any 

 comparative statements and hastily made without examining 

 the type or even an authentic representative of the species 

 condemned, are entirely uncalled for and generally of very 

 little scientific value. 



ADDENDUM. 



As the present paper was passing through the press, it was found that the 

 specific name exilis had already been employed for a species of Heterothops, 

 and I therefore substitute the word occidentis.
