AMERTOAN LEPIDOPTERA. 357 



vate. Fringes dark, cut with pale scales at the extremity of the iier- 

 vules. Secondaries blackish, becoming paler toward the base. A 

 discal spot and inner transverse line. An outer transverse shade 

 merged in the dark color of the terminal portion of the wing. Fringes 

 much as on primaries. Beneath, the primaries are mostly blackish, 

 sprinkled with whitish scales along the costal region and terminally. 

 Four ante-apical costal whitish dots. A discal annulated spot and two 

 dark transverse shade lines. Secondaries covered with mixed pale and 

 dark scales ; a distinct dark discal lunule and two parallel transverse 

 lines. 



Expanse, 50 ra. m. Length ofhodi/, 18 to 20 m. m. 



Habitat. — Atlantic District. (Penna.!) 



This fine species is of large size and the wings are unusually broad. 

 Hence with its purplish-grey color it has at first sight a resemblance 

 to certain species of Hadena or Eurois. The structural characters of 

 the body parts, however, indicate its position here with a degree of 

 certainty. A cursory examination of a specimen of X. capax, n. by 

 Mr. Lederer in Vienna, resulted in that Entomologist kindly giving it 

 as his opinion, that the generic position we assign to this Noctuid is 

 the correct one. 



ERA STRIA, Ochs. 

 Erastria synochitis, n. sp. 



% 9- Size small. Whitish. Antennae testaceous; the small palpi 

 are obscure testaceous. Collar and thorax whitish powdered with 

 blackish scales; the former edged behind with black and with abroad 

 central line. Under surface of the body and legs obscure whit- 

 ish tinged with testaceous; tarsi subannulate with brownish; hind 

 tibiae with two pairs of thorny subequal spurs. Abdomen crested to- 

 wards the base. Anterior wings pearly white, largely shaded with 

 dark olivaceous green. The transverse lines are obsolete. Basal por- 

 tion, within the orbicular, largely whitish except on costa; this pale 

 portion is margined outwardly and obliquely by the inner edge of a 

 median transverse green band, which fills the entire median space of 

 the wing below median nervure and obtains more narrowly superiorly 

 to costa between the ordinary spots, being limited here outwardly by 

 the short median shade line. The transverse anterior line may be de- 

 tected superiorly within the orbicular; it is more strongly marked on 

 costa; below the sub-costal nervure it seems to form a single inward 

 arcuation to median nervure, thence joining the inner edge of the me- 

 dian green band and running inwardly obliquely to internal margin. 

 The orbicular spot is white, faintly margined, irregularly shaped and with
