seem to associate it with the TripJiosa group; the single hind tibia left 

 on the specimens is very long, with two pairs of spurs and bent or 

 curved in a peculiar manner which may or may not be normal. 



Lygris (neolexia) xylina serrataria var. nov. (PL XXI, Fig. 9). 



In a previous paper we had restricted the type of xylina Hist, to 

 the S from New York in the Hulst Collection ; this specimen has 

 strongly pectinate antennae. In a series of 4 $ 's and 1 $ before us 

 from the vicinity of Ottawa, Ont. (Meach Lake, Que.), collected by 

 Mr. C. H. Young in July and received by us with the Taylor Collec- 

 tion, the antennae in the $ 's show very short pectinations, in fact they 

 can scarcely be termed more than strong serrations. The type of 

 maculation is distinctly the same as in typical xylina with brown median 

 band and basal area, the antemedian and submarginal areas being tinged 

 with yellowish ; on the secondaries the postmedian dark line is very 

 distinct, sharply dentate and scarcely at all shaded outwardly with 

 white. In view of the distinct difference in the S antennae we be- 

 lieve the form worthy of a name and propose using serrataria. For 

 the form found in the vicinity of Calgary, Alta. in which the $ an- 

 tennae are rather intermediate between serrataria and xylina in the 

 length of the pectinations and which shows a purplish tinge to the 

 median band the name speciosa Hist, may apparently be used although 

 the name is based on a rather aberrant specimen with reduced median 

 band ; at the time we referred speciosa as an aberration of xylina we 

 had overlooked the structure of the $ antennae. 



Thera georgii benesignata var. nov. (PL XIX, Fig. 3). 



Georgii Hist, was described from specimens from California, 

 Nevada, Washington, and Vancouver Is., B. C. The type in the Hulst 

 Collection is from Nevada and we would propose restricting the name 

 to this form which is the one found commonly all through the Sierras 

 (PL XIX, Fig. 4), being rather unicolorous smoky with the brown 

 median and basal bands poorly defined. The form found in Van- 

 couver Island is in general larger and much paler, the ground color of 

 primaries being at times almost white and the median and basal brown 

 areas contrasting strongly with the remainder of the wing ; we propose 

 the above name for this race ; the type $ is from Wellington, B. C. 

 (July 28, 1905) and the type 9 from the same locality (Sept. 12, 

 1903) ; we have besides 4 $ and 4 9 Paratypes from this locality 

 and from Duncans, B. C.
