the genus. At about the same time Dr. Boisduval published the species 

 under the name erato. This was the first known to us of any other name 

 for the insect. In his last work Dr. Boisduval disavows the authorship 

 of phaeton, but adopts the name for the species on our authority. I come 

 to the conclusion that the name " phaeton ' was transferred from some 

 other species by Dr. Boisduvars Californian correspondent, or that the 

 name "phaeton " was originally proposed by some other naturalist, per- 

 haps Dr. Behr or Lorquin. 



Oncocnemis Saundersiana, n. s. 



Fore tibiae with a terminal claw. Allied to Oncocnemis occata from 

 Texas and California. Differing as follows : Head and thorax black. 

 Median space darker than basal and terminal spaces, which latter are 

 washed with white. Median lines twice further apart inferiorly than in 

 occata. Median lines even, not scalloped. Median shade black, not very 

 diffuse. Ordinary spots larger • orbicular with an evident dark centre. 

 The dentations of the s. t. line connected, followed by a vivid white line. 

 Fringes wholly black, not checkered as in occata. Hind wings much as 

 in occata ; a terminal vague broad blackish band, within which is seen the 

 median line ; fringes white. Beneath less brown than in occata. Expanse 

 28 mil. Grimsby (Mr. Pettit). Two specimens. 



This is a very handsome, distinctly marked species, easily recognized 

 by the above contrast with its ally. Named for Mr. Wm. Saunders, of 

 London, Ont. 



Hadena illata. 



Agrotis insignata ||Walk., C. B. M., 353. 

 Agrotis illata Walk, ibid, 742. 



From a specimen in the D'Urban Collection, in the cabinet of the 

 Ent. vSociety of Ontario, deteruiined as "Agrotis illata' by Mr. Walker. 

 I find that the insect is a common Hadena which I had not hitherto 

 identified with certainty. Whether this name can be sustained for the 

 species I am doubtful, Mr. Walker's description being vague and even 

 contradictory, except as to color.
