:; bis. Catocala Robinsonii, Grote. 



£ £ . — I have alluded to this species above under C. insolabilis. The prima- 

 ries are evenly smooth, pale greenish cinereous, without shades. This is a lit- 

 tle stouter than C. insolabilis ; larger and of a different hue compared with C. 

 retecta. Median lines narrow and black. T. p. line acutely dentate ; subreni- 

 Ibrm open. Median shade perceptible above reniform narrowly on cOsta, else- 

 where not apparent. Median lines accompanied by pale shades. Subterminal 

 indistinct, dentate, consisting of a darker outer and paler inner shade line. 

 Hind wings black with white fringes. Beneath with narrow median white 

 bands on both wings. Expanse 75 mm. 



With the Californian species noticed by Dr. Behr, we have now 

 fifty-eight (58 ) described North American species of Catocala, nine of 

 which remain unknown to me.

Descriptions of North. American NOCTUIDAE.-Bfo. 1. 



BY AUG. R. GROTE. 



The typical specimens described in the present Series of Papers are 

 contained in the Collection of Lepidoptera now belonging to the Amer- 

 ican Entomological Society and separately preserved, formerly the pro- 

 perty of Mr. C. T. Robinson. 



These descriptions have been written preparatory to a Revision of 

 the North American Noctuidae, in which an attempt will be made to 

 define the genera more completely and in accordance with the more 

 recent classificatory views expressed by Lederer. — Dr. Herrich- 

 Schaeffer's system for designating the nervulation has priority, seems 

 the best and is used here. 



1. Hadena (mamestra) badistriga, n. sp. — % 9 —Palpi thickly 

 scaled, third joint small, concealed, maxillae moderate, eyes hairy. % anten- 

 nae simple, hind tibiae with two pair of small unequal spurs. Head and thorax 

 blackish brown, collar pale. Anterior wings pale along costal region to beyond 

 t. p. line. Ordinary spots obsolete. Of the usual lines only the t. a. and t. p. 

 lines evident; these black, narrow, single, continuous, distinct. T. a. line run- 

 ning obliquely outwardly, roundedly projected to base of cell, thence inversely 

 to internal margin. T. p. line evenly and greatly projected outwardly over the 

 Tiervules without the cell, below which it runs inwardly and forms a notch on 

 sub-niediau fold where it meets a broad blackish-brown shadeddash extending 

 from base of wing to this point. A second similar dash along the disc, stretch- 

 ing from t. a. line along median fold. The wing is shaded with brown, more
