cut with black on the veins. S. t. line irregular yellowish or gray, puncti- 

 form or continuous, preceded by a darker brown to black shading, the 

 terminal space usually paler. A series of brown or blackish interspaceal 

 terminal lunules. Orbicular rather large, oval, somewhat oblique, con- 

 colorous or a little paler, rather prominently ringed in yellowish or gray. 

 Reniforrn moderate in size, kidney shaped, gray or yellowish ringed, more 

 or less pale powdered, and sometimes completely yellowish. No clavi- 

 form. Secondaries rather even smoky brown, with a reddish tinge in the 

 male, especially defined on the fringes. Beneath rosy gray to reddish ; 

 primaries with disk smoky, secondaries paler basally and powdery. A 

 common extra discal line. Primaries with the s. t. line marked ; second- 

 aries with a discal spot. The male is more coppery red than the female. 



Expands i. 30-1. 50 inches = 32-37 mm.

Two males and five females, and each different from every other. 

 One male is almost uniformly carneous gray, the lines are not prominent, 

 the reniforrn contrasting yellowish. One female is evenly blackish brown, 

 the median lines reduced to the pale included spaces, and the ordinary 

 spots narrowly pale ringed. A third form has all the maculation sharply 

 defined as described, and the terminal space is decidedly paler than the 

 rest of the wing. Between these three types the variation ranges. The 

 cell may be also darker, even blackish, or may be entirely concolorous 

 with the remainder of the wing. One specimen recalls Platagrotis condita, 

 another resembles Adelphagrotis stellaris. 



The specimens were sent me by Dr. Fletcher, who tells me that he 

 knows the early stages, and that Mr. Young has bred some of the examples 

 submitted to me. It will be his pleasure to add to the history of this 

 unusually variable and interesting species. The dates on the specimens 

 before me range from August 19 to September 7. 



Camcades infusa, n. sp. — Ground colour smoky brown, varying a little 

 to a violaceous shading. Head and collar a little paler, the latter with a 

 slender obscure black transverse line. Thorax concolorous, posterior tuft 

 tending to become a little discoloured. Primaries with costa a little 

 paler, tending to yellowish at the base, not discoloured or strongly con- 

 trasting. The median lines are practically wanting. A curved black 

 mark at base below median vein does not quite reach the place of the t. a. 

 line. T. a. line marked by a black spot in the cell, by a cross-line closing
