Mamestra repentina Morr.

Grayish, pale ; mediaii space fuscous, mecliau lines distinct, geminate. 

 Basal line distinct, geminate, included space fuscous; t. a. line upright,

Expands 33'"°' (1.20 inches). 



Habitat. — West Hoboken, Xew Jersey. 



The 9 type from Mr. Meyer's collection is the only specimen exam- 

 ined. The insect is very different from all its congeners and should be 

 easily recognized. It is passing strange that in a locality so well col- 

 lected over, specimens should not have been found since, and it gives 

 rise to a susiDicion that it is not really an American insect. One col- 

 lector at least, in the good old time, distributed exotics as taken at 

 Hoboken; witness iSphinx Ugustri and convolvuH in my own collection, 

 declared upon the most solemn assurances taken at West Hoboken! 



Mamestra brachiolum Harv. 

 1876. Harv., Can. Ent., viil, 6; Mamestra. 



Dark ash gray, powdery, median space darker, median lines present,

 crenate, parallel with outer margin ; s. t. line pale, sinuate, interrupted; 

 a narrow black terminal line ; an obsolete, irregular black line crosses 

 median space between ordinary spots ; claviform faintly indicated or 

 wanting; ordinary spots moderate, pale; orbicular round; reniform 

 kidney-shaped ; secondaries smoky fuscous, paler at base ; beneath,

Expands 27'""» (1.08 inches). 



Habitat. — Texas, Arizona. 



Bears a resemblance to cuneata in maculatiou, and compared with 

 that species by Dr. Harvey. It is, however, less distinctly marked than 

 that species, though much after the same style. In wing form this 

 species differs also in having the primaries somewhat narrower and
