186. 0. cibalis Grt.? — Sir George Hampson makes the Calgary form 

 "Subspecies i of cibalis, describing it by comparison : Thorax and fore 

 wing grayer, the latter more uniform, and without the whitish patches in 

 the interspaces ; the dentate black marks before subterminal line more 

 developed between veins 6 and 2 ;.tegulae produced to a dorsal ridge." 

 He figures as typical cibalis a male from Glenwood Springs, Colo. The 

 figure shows a strong rufous brown shade over a large portion of the 

 primaries, which, however, he does not mention in the description. I 

 compared the specimen with his figure, and made no criticism upon the 

 latter. Moreover, I have a good series from Eureka, Utah, which fit the 

 figure perfectly. 



My note on Prof Smith's material reads : "Utah and Colo, specimens 

 are more pale streaked than my form, but one from Colo, grades in.'' 

 This is in accordance with Hampson's diagnosis, nor do I seem to have 

 observed brown shades shown in his figure and in my Eureka series. At 

 Washington I wrote : "One 'Colo.' and one 'Glenwood Springs' are like 

 Hampson's figure. But two Denver males, one of them labelled 'W. S. 

 Foster,' are exactly like Calgary specimens here, and I should say these 

 are almost certainly two species." My own Calgary and Utah series sug- 

 gest the same, very strongly. But which is cibalis remains to be discov- 

 ered, as I have not seen Grote's description, and the type, which Prof. 

 Smith's Catalogue states to be from Colorado, and in the Graef collection, 

 I appear to have overlooked. Holland's figure represents the Calgary 

 form (which also occurs in Manitoba) exactly. The origin of the speci- 

 men figured c^n only be surmised by his statement on page 176 : ''The 

 only specimens so far have been taken in Colorado." 



187. Rhynchagrotis gilvipeimis Grt. — Prof. Smith in his "Revision 

 of Agrotis" places gilvipennis first in his then new genus RhynchagrotiSy 

 considering it, it is to be supposed, the most typical, making our species 

 a synonym oi chardinyi Bdv. He remarks on page 14 : "Mr. Grote first 

 stated that the fore tibite in his specimens were spinose, but I have never 

 been able to discover any." In his reference to chardiiiyi he merely fol- 

 lows Morrison and Grote. In his Catalogue he corrects this and makes 

 gilvipefuiis a good species. Sir George Hampson places most of our 

 species q{ Rhynchagroiis'vci Triphaiia Hiibn., but retains Smith's genus for 



September, 1911
