150 THE CANADIAN ENTOMOLOGIST. 



Four ^ and two 9 examples are at hand. The species resembles 

 Calgary at first sight, but differs in that the median shade line is 

 dislocated on the median vein and, instead of continuing an even course 

 across the wing, resumes it below the reniform and runs close to the t. p. 

 line. There are other superficial differences and the genitalic structure is 

 distinctive: but the character just pointed out should enable the species 

 to be recognized. 



Euxoa pestula, n. sp. — Ground colour a dull smoky luteous, more or 

 less powdered with bluish-gray, brown and black ; but never so as to 

 obscure the luteous base. Head with a dark frontal and inter-antennal 

 line, the dark shade ranging from brown to black. Collar with a some- 

 what obscure brown or blackish median line, surmounted by a distinct or 

 even prominent gray line. Thorax not otherwise definitely marked. 

 Primaries with all the normal maculation well defined, though not promin- 

 ent, and in some examples there is a distinct ferruginous dot or spot at 

 the insertion of the costal margin of primaries. There is no basal dash or 

 mark below the median vein. Basal line distinctly geminate, blackish, 

 included space a little paler than the ground. T. a. line geminate, 

 blackish, a little o'utcurved in the interspaces and, as a whole, a little 

 outwardly oblique. Included space of the ground colour or a little paler. 

 T. p. line geminate, not very well defined, inner portion more or less 

 lunulate, outer more even and tending to form a series of venular points. 

 As a whole, abruptly bent on the costa, outcurved over the reniform and 

 then nearly parallel with outer margin. S. t. line pale, a little irregular, 

 preceded by a dusky costal patch and an ill-defined dusky shading, fol- 

 lowed by a terminal space, which is darker, except at apex. Median shade 

 line distinct, though scarcely prominent. It is single, starts from costa 

 between the ordinary spots, bends to the base of the reniform, then runs 

 parallel with and close to the t. p. line. Claviform rather small, outlined 

 in dark scales, not otherwise contrasting. Orbicular oval, oblique, open 

 to the costa, gray-filled, not otherwise well defined. Reniform large, only 

 a little lighter than ground ; kidney-shaped, tending to a pale annulus. 

 Secondaries yellowish at base, smoky toward the outer margins. Fringes 

 white, or whitish with a dusky interline. Beneath smoky, secondaries 

 paler and more powdery, both wings with an incomplete outer line and a 

 small discal spot. 



Expanse, t. 25-1.50 inches =31-3- mm.
