332 THE CANADIAN ENTOMOLOGIST. 



Montreal and Ottawa specimens, some of which can be mated exactly 

 with some from Manitoba and Alberta. As is usual with certain prairie 

 forms, most from the latter places are rather smaller and less distinctly 

 marked than those from the east, but the differences are not constant. A 

 Kaslo series does not differ, but one from Vancouver Island shows a 

 rather strong gray irroration. in some specimens, though nothing to 

 indicate a distinct species. Incidentally, Jiaruspica seems to have been 

 merely a change of name for what Morrison named unimacula the 

 previous year, as his name was in use by Staudinger in the genus in 

 Europe. But Staudinger and Hampson both list unimacula Stand, as a 

 variety oi p/ecta, and Hampson restores Morrison's name, which should 

 now be used for Jiaruspica. Grote's type of Jiaruspica is in the British 

 Museum, and is presumably also Morrison's type of unimacula, though I 

 do not know that for certain. 



Whether sierrce is a distinct species is doubtful. Hampson ascribes 

 to inopinatus an entire orbicular, and an open one to sierrce, of which he 

 has the type from the Sierras. This is a variable character in inopinatus 

 ( = unimacula). I have specimens from Colorado and Utah which seem of 

 rather slighter build, and are rather darker in colour, though with 

 secondaries paler basally, A few have an edging of faint yellowish gray 

 scales to the transverse lines, and a fine continuous line of the same colour 

 at the bases of fringes. But two or three of the specimens seem to stand 

 equally well in either series. 



218. N. unicolor Walk, was described six years previous to clandes- 

 tina Harris, and, following the law of priority, Sir George Hampson justly 

 gives it preference, though the pity is that the change was not made 

 sooner, the synonymy being admitted. Walker's type is a female from 

 ■"iVenton Falls, N. Y. (Doubleday), and is the species universally known as 

 clandestina, of which, however, I have not seen Harris's type. 



219. N. Jiavilce Grt. — I have occasionally taken more specimens of 

 this here, and have some from High River from Mr. Thomas Baird. I 

 have it from San Francisco, and have had a lot from Stockton, Utah, in 

 which unicolor ( = clandestina) was not included. From the latter locality 

 I have one compared with the type, a male from Nevada, in the British 

 Museum. It was originally described as a variety oi clandestina, but though 

 closely resembling that, and easily confused with it, its distinctness is 

 universally admitted. In colour it may be generally described as grayer
