the base of the wing ; 5 weak ; cell open ; 6 out of 7 beyond, not before, 

 a slight projection, on 7, which projection indicates the position of the 

 cross vein. It will thus be seen that the neuration differs sensibly from 

 that of the Bombycice ( Cymatophoridcz H. S.) The position of vein 5 is 

 different from that in the Noctuelitce; but attention is called here to the 

 fact that in the genus Nolaphana (which possesses ocelli) vein 5 is nearly 

 midway between 4 and 6 on primaries. 



Ellida gelida is a gray moth, having a superficial resemblance to 

 Pseudothyatira expidtrix. The collar is discolorous, pale buff, recalling 

 that of Pygaera pucephala, edged with black. The wings are long, costa 

 of primaries convex. Interior line represented by three parallel curved 

 black lines, obsolete inferiorly. A black curved streak in a whitish shad- 

 ing on the disc. Outer and subterminal and basal lines faint. Outer line 

 dentate. Between the subterminal shade and the very narrow even con- 

 tinued terminal line at base of fringes, is a distinct line of blackish brown 

 hue, narrowly interrupted on the veins and inferiorly disconnected in the 

 female specimen before me. Hind wings uniform pale fuscous, with 

 whitish fringes. Beneath whitish fuscous, with a line and spot on hind 

 wings. Expanse 42 mil. 



SYNONYMY OF THE COLEOPTERA OF THE FAUNA 

 BOREALI-AMERICANA, KIRBY. 



BY GEO. H. HORN, M. D., PHILADELPHIA, PA. 



Since the reprint of Kirby's Fauna Boreali- Americana began, much 

 has been learned concerning the species of Coleoptera therein described 

 or mentioned, so that at the present time very few remain unidentified. 

 Through the kindness of the authorities of the British Museum, every 

 facility was granted to Dr. Leconte and myself for the study of Kirby's 

 types, and the results of these studies have already been made known by 

 Dr. Leconte. It will be noticed in very many places that the synonymy 

 here given differs very greatly from that given by Mr. Bethune, who com- 

 piled from the best known sources all that was at the time known or 

 guessed concerning Kirby's species.
