260 THE CANADIA.N ENTOMOLOGIST. 



indicated by a few black scales. T. a. line geminate unusually far from 

 base, outer defining line blackish, inner scarcely traceable, except for 

 the somewhat paler included shade, outwardly oblique, irregularly out- 

 curved in the interspace, and reaching the inner margin at about its middle. 

 T. p. line geminate, not much out-curved over the cell, and only a little 

 in-curved below ; inner defining line blackish and partly lunulate, outer 

 even smoky, broken and almost lost below vein 3. S. t. line very even, 

 of the ground colour, defined by the darker terminal space and a dusky 

 preceding shade. A series of black, small, terminal lunules. Orbicular 

 . barely indicated by a few blackish scales. Reniform large, upright, sub- 

 quadrate, as a whole paler than the ground colour, so as to be relieved 

 and somewhat prominent. Secondaries smoky, fringes whitish. Beneath 

 smoky with pale powderings, a common outer line, and on secondaries 

 with a discal spot. Vestiture of the legs and breast with a reddish tinge. 



Expands 1.60 inches = 40 mm. 



Habitat : Garfield Co., Colorado, 6,000 feet (Bruce). 



A single female which has been awaiting a mate some ten years 

 or more. The species has the wing-form and general habitus of 

 passer, Gn., but it is unlike any of the forms of that variable species. It 

 has scarcely a trace of a claviform, and the complete neatly defined s. t. 

 line, and very oblique irregular t. a. line, will serve as further distinctive 

 features. 

 Hadetia aliecto, n. sp. 



In maculation almost like madata, all the observed differences 

 being well within the range of variation ; but without a trace of the 

 reddish or brown shadings of the old species ; all is black and gray. 

 The median space is the darkest part of the wing, the ordinary spots 

 being very large and of the paler ground, save for a central filling in the 

 orbicular. 



Expands 1.40 inches = 35 mm. 



Habitat : Calgary, Sept. 17 (Dod) ; Brandon, Manitoba (Hanham); 

 Volga, So. Dakota (Truman). 



Six specimens, representing both sexes, are before me, and do not 

 vary a single mm. in expanse. I considered them for a long time as a 

 local race of madata, and so named them for my correspondents who 

 have other specimens of this species. In actual ornamentation there is no 

 appreciable difference, but the difference in colour is constant, and the 

 genitalia of the male confirm the distinctness of the more western form, 

 though the general type is the same.
