following the same practice : as Amorpha Populi and Populeti, Milto- 

 christa Rosaria and Rosacea, etc. It is also not a very uncommon thing 

 to see the same name used in a family in related genera without any 

 change. As an instance of this, in Dr. Skinner's new catalogue of "North 

 American Rhopalocera," 1898, we find Diadema Misippus, and in the 

 next genus Liinenitis Misippiis. In these species the female of the first 

 is coloured and marked so much like the second in both sexes that they 

 might easily be mistaken for each other by an amateur. Yet the writer 

 has seen no criticism on Dr. Skinner's course in the use of these names. 

 The same thing was found in a catalogue of Star Fishes, where the specific 

 name Miliaris was used in two related genera of the same family. How. 

 ever much we may regret that names with only a slight difference in ter- 

 mination have been used, or the same name for two species in related 

 genera of a family, when the names have been published and used it seems 

 best to the writer to let them alone. Indeed, I do not believe any one 

 has a right to change them. In the case before us there is no danger of 

 confounding Viduaia and Vidua, for the two insects are very different, 



In regard to the two v\z.mes,Judit/i, Strecker, and Levettei, Grote, the 

 dates of the published papers in which the descriptions occur give Strecker's 

 name the priority. We have decided to take the " face of the returns" as 

 evidence in this case without taking up the differences of the two authors. 



In looking over the collection of Dr. William Barnes, of Decatur, 111., 

 a new species was found which the Doctor kindly placed at my disposal. 

 In the description that follows, the writer has dedicated the species to its 

 owner by the use of his name for the species. 

 Catocala Barnesii, nov. spec. 



Expanse, 2.63 inches. General or ground colour of the fore wings 

 rather dark olive gray, not so dark as that of Obsacra, but between that 

 species and the colour of Robinsonii, the lines faint and much the same as 

 they are in the latter species, the insect in general reminding one of 

 Robinsonii, but it is smaller and darker, standing in size between Robin- 

 sonii dixxd Judith. Comparing the markings with those of Robinsonii, the 

 t. a. line is oblique, reaching the posterior margin close to the t. p. line 

 as in Robinsonii, but the costal portion is heavier ; the shade over the 

 reniform is rather heavy ; the reniform with only the inner part of its ring 

 visible This portion black, the rest concolorous, while in Robinsonii the 

 reniform is brovvn ; subreniform whitish, closed or nearly so, in colour 

 paler than in Robinsonii, and in that species it is wide open ; t. p. line
