7G THE CANADIAN ENTOMOLOGIST. 



inqucesita, necopina and nitela. This appears to me a reasonable view 

 when we consider the markings of the Noctuids as a whole. 



It is a delicate question whether we should prefer the name given to 

 the variety, when described on the same page as the species, merely 

 because it stands first. I do not think it subserves the practical ends of 

 science. For instance, I prefer the name Orthosia ferrugineoides for our 

 common species, and record bicolorago as designating the aberration, 

 although the latter stands first in Guenee. It is pushing priority beyond 

 what the law intends. But if nebris and bicolorago were first described by 

 another author and in another book, their priority for the species would 

 be undoubted. 



I was also much interested by Mr. Lyman's paper in the January 

 number. In the Annals of the N. Y. Lyceum N. Hist., Vol. VIII., 1866, 

 will be found a paper by Grote and Robinson, Lepidopterological 

 Contributions, with three coloured plates, in which we originally drew 

 attention to Abbot's figuring two species on Plate 78 of the Insects of 

 Georgia. We then gave the following synonymy on page 374, /. c: 



(1) Lophodonta georgica. 



Phalcena angulosa, Ins. Ga., 78 [S3], J , upper left-hand figure (1797). 

 Notodonta georgica, H.-S., Ex. Lep. 3S4, $ ( x ^55)- 



(2) Lopliodonta angulosa. 



Phalcena angulosa, Ins. Ga., 7S [83], $ ?, lower right-hand figure (1797). 



Lophodonta angulosa, Packard, P. E. S. P., 358 (1864). 

 It is not certain that the lower right-hand figure represents a female. 

 We gave particulars which render it possible that this figure also 

 represents the male sex. The name angulosa became restricted to this 

 species by Herrich-Schwffer's description of georgica. 



CHANGES IN ENTOMOLOGICAL FAUNA OF NORTHERN 



ILLINOIS. 



BY F. M. WEBSTER, WOOSTER, OHIO. 



Among the ways I find that one can study the changes in the insect 

 fauna of a locality as years go on is to occasionally go back to some such 

 section where one has years ago been familiar with the insects to be found 

 there and note the number of newcomers or, possibly, the passing of some 

 of the old ones, though these last are by far the less numerous of the two.
