This latter determination is clonbtfnl us yet; the Californian spe- 

 cies strongly resembles A. Cochrani from the Eastern slope but seems 

 stouter and looks like Herrich-Schaeffer's figures above cited. 



Mamestra distiucta. 



Hadena distincta (Hiibn.) Grote, List. N. Am. Noct. p. 15. 



At the time I prepared the List I had no specimens of this species 

 for examination. I owe a specimen to the kindness of Dr. Ilagen, 

 taken in Texas, and which enables me to correct my former generic 

 reference. 



Mamestra vicina Orote. 



A species of medium size ; with liairy eyes and unarmed tibiae, apparently 

 related to M. davixilena. The costa is a little depressed and the apices produced. 

 The color is blackish gray, not blackish brown as in its ally. The narrow, 

 basal, longitudinal black streak is evident. Basal half line widely geminate. 

 The median lines are approximate inferiorly below the median vein, narrowing 

 the median space and, on the submedian interspace, the large black outlined 

 and shaded claviform spot attains the t. p. line. The ordinary spots are rela- 

 tively large, pale, whitish, very faintly warm tinted, the orbicular rounded 

 ovate, proportionally large, the reniform inwardly distinctly black margined, 

 but slightly outwardly constricted and here more vaguely defined. The t. p. 

 line is scalloped interspaceally, apparently geminate with included whitish 

 gray shade, but the outer component line is lost. The subterminalline is nar- 

 row, whitish gray, not very distinct, irregular, forming no W mark, preceded 

 and succeeded above internal angle by a distinct black dash on the submedian 

 interspace. An even continued blackish terminal shade ; the veins terminally 

 marked Avith blackish ; the fringes narrowly pale opposite the extremity of the 

 veins. Hind wings pale fuscous with soiled veins ; fringes whitish with an in- 

 ternal line. Body parts concolorous ; abdomen tufted on the dorsum, especially 

 centrally ; ovipositor not exserted.

Hadena castauea Orote. 



3 $ . — Allied to the European Hadena ruhrirena, compared with a specimen 

 of which and llerrich-Schaeffer's fig. 57, our Californian species seems a wider 

 winged and heavier insect, less brightly marked and with a dark streak along 

 the submedian fold on the median space wanting in the European species. 

 Fore wings dark brown ; blackish along the terminal space. The ordinary 

 lines are black, obsoletely geminate, much as in the European form. Ordinary 

 spots large, concolorous, the claviform outlined, the reniform very large and 

 with a more or less decided ycdiow stain resolved into Gortyna-like spots out- 

 wardly. A black shade along the submedian fold on the median t^jiace. Sub-
