with scarcely defined white spots and fasciae placed as follows: 

 a spot in the fold near base; a quadrate spot on basal third of dor- 

 sum reaching just beyond fold; just beyond middle a transverse 

 fascia; at apical fourth of costa a spot reaching about halfway across 

 the wing. Hind wings and cilia gray, darker than the fore wings, 

 with purplish iridescence, thinly scaled. Legs gray. Expanse, 15 

 mm. 



Type (cf ), Two Medicine Lake, July 16; in dry meadow^s. 



In this specimen, veins 7 and 8 of the fore wing are coincident 

 as in Greya, but the other characters and the general habitus of the 

 insect are those of Lampronia. As shown bj'- the following species, 

 such individual variations occur. 



Lampronia variata n. sp. 



Palpi brownish gray, labial palpi wdth whitish scales above; an- 

 tennae black; head brownish, some whitish hairs on the face. Tho- 

 rax and fore wings shining bronzy brown; at basal third of dorsum 

 a pale yellowish spot reaching the fold; just before tornus a pale 

 yellowish spot reaching two-thirds across the wing. Tips of cilia 

 whitish. Hind wings dark browai wdth a faint purple luster. Legs 

 c/ ark brown. Expanse, 11 mm. 



Type (cT), Two Medicine Lake, July 16; paratypes (cf and 9), 

 Two Medicine Lake, July 15, in forest openings. 



In some of these specimens 7 and 8 of the fore wings are coin- 

 cident. 



Lampronia politella Walsingham. 



Three males, Two Medicine Lake, July 15, Going-to-the-Sun, 

 July 21, collected in early morning in the dry meadows. The ex- 

 panse, 18-20 mm., is somew^hat more than that given by Walsing- 

 ham; but in other respects, these specimens agree closely with the 

 description, showing very markedly the aeneous tinge of the fore 

 wings. 



Lampronia piperella Busck. 



Two Medicine Lake, July 15, in dry meadows; one female speci- 

 men which has all the veins of the fore wing present and palpal 

 characters as in the other species of the genus, and not as described 

 for the very similar Greya punctiferella Walsingham. 



CHALCEOPLA nom. no v. 



This generic name is proposed to replace Cyanauges Braun (Ohio 

 Jour. Sci., XX, 24, 1919), preoccupied by Cyanauges Gorham in 

 the Coleoptera.
