* This generio name should probably be rejeoted for the speoies here mentioned ; 

 it was proposed (Ann. Soo. Ent. Fr. 1st, ii, 136), for species with ramose antennae; 

 the universally known and common species, atra Fabr., is not mentioned among 

 them, and is referred to by Laporte under Lucernuta, the second division of 

 Photinu.t, as No. 25, P. laticorni.i, ibid. 144. It is quite evident that the super- 

 ficially observed characters used by him, like those of Motschulsky, can have no 

 significance in a system like that which I have here attempted to introduce, for 

 the very next species of Photinus {Lucernuta), is described as having a " luminous 

 spot at the middle of the fourth ventral segment." This position of the light- 

 organ, barring the error in the numbering of the segments would place at least 

 that speoies of Lucernuta in the neighborhood of Pyractomena. In the confusion 

 of nomenclature thus produced it would perhaps be easier to retain for our species, 

 and for as many from tropical America as are found to be congeneric with them, 

 the Dejeanian name Lychnuris, fir.st defined by me in Proc. Acad. Nat. So. Phila. 

 ii, 332. Since, however, I am neither a "purist," nor " resurrectionist," but an 

 humble conveyor of thought, endeavoring only to state distinctly the relations 

 of the objects of which I have occasion to write, I leave this and many similar 

 questions for those whose tastes lead them in another direction.
