306 THE CANADIAN ENTOMOLOGIST. 



(to use the language of the Canon referred to) by Mr. Groie and Dr. 

 Lintner. Therefore, I cannot understand how Guenee's name can be 

 consistently applied to Dr. Lintner's tricosa, and it is not in accordance 

 with the rule of nomenclature just cited. The fact that the form which 

 agrees with the main part of Guenee's description and with his figure may 

 or may not be a synonym oi subgothica, Haw., does not affect the case in 

 any way. I believe Mr. Grote is right in his protest (Can. Ent , XXIII., 

 151) against the resuscitation oi jaculifera at the expense oi tricosa. 



As has been stated. Prof. Smith's synonymy is founded principally on 

 the statement of Mr. Butler that '■'■tricosa, Lint., is \.yp\ca.\ Jaadifera ; 

 herilis is a poor variety." The antennal differences between herilis and 

 tricosa, pointed out by Prof. Smith, show that Mr. Butler did not study 

 the species very carefully. The other point has been discussed by Mr. 

 Grote as follows : " Guenee happens to figure typical jaculifera and he 

 figures typical stibgothica ! Prof. Smith does not quote Guenee's illustra- 

 tion, which contradicts both Butler's statement and his own course. 

 Guenee's types of '■jaculifera,^ or so-called ' types,' were several in 

 number at least, as he included two other species as varieties. One of 

 these so-called types Mr. Butler may have, and this may be a tricosa, 

 Guene'e's var. A. Guenee made three mistakes as to his material : First 

 he described and figured subgothica as jaculifera ; then he described 

 specimens belonging to two different species, tricosa and herilis, as 

 varieties oi jaculifera. Under no circumstances can Butler's statement 

 be correct (Can. Ent. XXIII., 151)." The enlarged figures (twice 

 natural size) of a front and hind wing of each of the three species just 

 discussed show some of their differences and will aid in their determin- 

 ation. I believe the above evidence warrants the following synonymy for 

 these much-discussed forms : 



subgothica, Haw. 



jaculifera, Gn. (type and figure). 



tricosa. Lint. 



jaculifera, var. A, Gn. 



herilis, Grote. 



jaculifera, var. B, Gn., 

 or the same as that given by Dr. Lintner in detail in 1874 (Ent. Cont., 

 III., 161), and accepted by Mr. Grote until recently. 



Shall it be Agrotis, Feltia, or Agronoma subgothica, Haw. } 

 Apparently Mr. Grote and some other systematists are not yet ready to
