250 REVISION OF MAMESTRA SMITH. 



aries smoky fuscous. Beneath, powdery, secondaries with double outer 

 lines more or less evideut, and dark discal spot. 



Expands 27-30'^"> (1.08 to 1.20 inches). 



Babitat. — New Jersey, West Virginia. 



A single, poor specimen from New Jersey is in the Museum collec- 

 tion (C. V. K.). 



1 have seen the types of both Morrison's and Grote's species and 

 they are identical in specific characters. The species is readily known 

 by the bright coloration and the prominent yellow s. t. line. 



The harpes are semi-chitinous, inferiorly with a thickened chitinous 

 margin. The tip is somewhat narrowed, lappet-like. From the cor- 

 neous inferior margin arises a short, cylindrical, corneous clasper, and 

 behind this a small beak-like process. 



Group RENIGERA. 



The four species that are placed in this group, though very distinct 

 in color and maculation, are yet closely allied in structure. They are 

 all small, rather plump forms, with short, obtuse primaries, fringes 

 rather long and thoracic tuftings distinct. The abdomen is tufted only 

 at base, and that indistinctly, but is furnished in the male with evident 

 lateral tufts. The male antennae have the joints well defined and 

 ciliated, without being serrated. The male genitalia are alter the one 

 type. The harpes are broad at base, suddenly narrowed or deeply 

 emarginate at upper side, leaving an acute, pointed tip, inwardly mar- 

 gined with spiuules. The clasper is a long, slender, curved hook. 



Benigera is darkest, with i)romineutly marked green reniform. There 

 is a green patch at base and another near hind angle. The claviform 

 is black. 



Egens is usually paler, lacks the green patches, but has the reniform 

 outlined in white. The claviform is not at all prominently marked. 

 Tlie darker forms are Mr. Grote's cinnaharina^ the paler forms have 

 been named ferrea, also by Mr. Grote. 



Spiailosa is a very pretty species, diftering from the preceding by 

 the distinct median lines and neatly outlined ordinary s])ots. The 

 reniform is not prominently white marked and the veins are pale through 

 median space, 



Circumcincta is marked like egens, but has the gray color and super- 

 ficial appearance of olivacea, connecting the two groups. 



A table is scarcely necessary for the definition of these forms.
