178 THE CANADIAN ENTOMOLOGIST. 



compared, and if it can be made to apply to any one example, then 

 ochrogaster may be confined to the species ; if not, then it seems to me 

 not. As to ///a/a, Walker, Canadian specimens seen by me so labelled 

 were suffusca, to which Walker's description might well apply. It would 

 require evidence to make me believe that Walker's supposed type in B. 

 M. is authentic. 



" A little larger than plecta, which it resembles in markings." (It 

 seems to me this cannot well be said of iurris.) "The red of primaries 

 is paler" (this is, then, a reddish form, like gu/ar/s), "and the sub- 

 terminal line is well marked by a dark blackish shade. The terminal 

 dots are rounded and separate ; the fringe is divided by a dark line ; the 

 spots are much larger ; the reniform less constricted, and the median 

 vein evenly white." (This latter does not seem to agree with gu/ar/s.) 

 " Hind wings with a very distinct terminal series of rounded dots. 

 Collar ochrey white, as also the abdomen, which is unicolorous and with- 

 out the terminal reddish tuft (/. e., of plecta). Am. Sept.; coll. Bdv.; one 

 male." 



The comparison by Guene'e with plecta led me to seek for a form 

 more resembling plecta than either turris or gu/ar/s. This is a matter to 

 be left to some unprejudiced observer, who will compare sufficient 

 material with above description. Agrotis turris seemed to me allied to 

 the Californian, A. Wilsoni. 



3. Catoca/a microuympha, Guene'e, III., 102. 



"Shape and form of protonympha, which it is very near, and from 

 which it is only distinguished by slight, though constant, characters- 

 Such are the more pointed apices, more brownish shade of colour, the 

 shape of t. p. line, the band of hind wings more angulate, the [markings 

 of the] base of primaries beneath, the thinner palpi, etc. Fore wings 

 slightly dentate, costa arching outwardly, apex quite sharp ; of a chest- 

 nut brown, varied with whitish-gray and blackish. The two median 

 lines distinct, but narrow, separated above and approaching below ; the 

 t. p. line forming, at end of cell, a strong bend, with two teeth, of which 

 the inferior is almost obsolete, after which the line is nearly regularly 

 waved, without any inward bending below submedian vein, which latter 

 is shaded with black throughout its length. Reniform replaced by a 

 simple black mark. Median shade well marked, but interrupted on cell, 

 and turning thence towards terminal margin, where it stains with blackish
