324 THE CANADIAN ENTOMOLOGIST. 



fuscous ; fringes with a pale line at the base. Beneath, gray powdered. 

 Secondaries usually with a darker discal spot. None of the examples 

 that I have seen had any maculation on the primaries. 



Expanse .80 to i inch = 20 to 25 mm. 



Habit at. ^G\e.nyfood. Springs, Colo., Aug. ; Dr. Barnes. Garfield 

 County, Colo., 6,000 feet; Bruce. Calgary, Canada, July 9th, i6th, 19th 

 and 27th ; Mr. Dod. 



Thirteen specimens are under examination and others are in collec- 

 tions. This is an ally oi Icevigata^ with the same type of maculation; but 

 considerably smaller in size. It is as variable in colour as the other 

 species ; but in this case the females are the darker and smaller as a 

 whole, while the males are brighter and have the contrast much better 

 marked. In all the specimens the black line connecting the ordinary 

 median lines is well marked. In all specimens the dorsal tuftings, par- 

 ticularly in the male, are obvious. 



Lathosea ursiiia, n. sp. . 



Ground colour a very pale whitish-gray, the maculation black or 

 smoky bro\Vn. Head and thorax without markings ; the vestiture very 

 long, hairy, loose, and a little mixed with brown and gray, so as to give a 

 somewhat powdery appearance. The sides of the palpi are blackish. 

 Primaries with all the transverse markings obliterated. The most 

 obvious ornamentation is a series of black dashes in the interspaces 

 beginning between veins one and two and extending to just below the 

 apex ; in all five of these blotches arranged in an oblique series. A 

 brown shade extends through the cell and the median vein is bordered 

 on both sides with blackish. A black basal dash extends a short distance 

 through the submedian interspace, and another black dash marks the 

 internal angle. Vein one is also usually black marked. A brownish 

 shading occupies most of the centre of the wing, leaving the costal 

 and terminal spaces a little paler, though the white powdering sometimes 

 extends also along the internal margin. The ordinary spots are vague, 

 pale, without defining lines : the orbicular transversely oval ; the reniform 

 an indefinite small lunule. The veins are more or less powdered with 

 black. Secondaries smoky gray, with a more or less well-defined discal 

 lunule, which is rather a reflection of what is found on the 'under side. 

 Beneath whitish, powdered with gray, the veins darker marked. The 

 secondaries with a fairly well defined discal lunule in most specimens. 



Expanse 1.40 to 1.60 inches = 35 to 40 mm.
