PLATE XVII 



Fig. I. EuxoA ORBICULARIS Sm.? Pyramid Lake, Nev. $. 



This figure together with figs. 2, 8, 9, 15, 16 form a variable series of 

 what is possibly the above species. We have a colored figure of the type 2 in 

 the Tepper Collection with which these agree fairly well ; Nevada is also given 

 as the type locality. Our series shows considerable variation in the distinctness 

 of the maculation and the bordering of the ordinary spots ; the $ $ show also 

 a distinct reddish tinge in the ground color, lacking in the 5 9; we can, how- 

 ever, find no distinctive features which would warrant a separation. 



2. EuxoA ORBICULARIS Sm. ? Pyramid Lake, Nev. $. 



3. EuxoA sp. Pyramid Lake, Nev. $ . 



It is possible that this and fig. 10 may represent extreme varieties of 

 the species represented by our figs. I, 2, etc. These two specimens, however, 

 have a distinct black transverse line on collar, a black basal dash and traces of 

 black spots before the subterminal line, features all lacking in the former series. 



4. EuxoA DETESTA Sm. ? Eureka, Utah. $ . 



There is considerable doubt as to what the true dctcsta Sm. is. It is a 

 name proposed for the species wrongly identified by Smith in his Revision as 

 choris Harv. and is without a type. We have a specimen from Arizona labelled 

 delcsta by Smith which agrees well with the specimen figured, with the exception 

 of the central shading being more ochreous in the Arizona specimen. The pe- 

 culiar suffused light shading in the central area of primaries render this species 

 easily recognizable. 



5. EuxoA DIVERGENS Wlk. Hymers, Ont. (June 8-15). 2. 

 A very strongly marked and fresh specimen. 



6. EuxoA QUADRiDENTATA G. & R. Truckee, CaHf. (July 1-7). $. 



This and fig. 13 may represent the two sexes of the species recently 

 described by Smith as Euxoa flutca from Sierra Nevada, CaHf. In a series of 

 10 specimens before us, all from Truckee, there is considerable variation shown 

 as regards the distinctness of the saggitate black subterminal marks and the 

 white rays on veins 3, 4, 6 and 7 ; in certain specimens either the one or the 

 other or even both may be scarcely traceable.

Our specimen is almost from the type locality (Brandon, Man.) and
