fHE CANADIAN ENTOMOLOGIST. 12a 



Alar expanse, 13-14 mm. 



Habitat: Plummer s Island^ Maryland; Pittsburg, Pennsylvania; 

 Jiuie. U. S. Nat. Mus. Type No. 9795. 



Nearest in general habitus and coloration to the group of G. 

 mediofuscella, Clemens ; Pennsylvanica, Dietz, etc., but quite distinct in 

 design. 



Mompha stellella, new species. — Antennae unicoloured, dark brown. 

 Labial palpi whitish ochreous, sprinkled with black scales, and with a 

 black annulation just before the tip of terminal joint. Face silvery white. 

 Head and thorax light ochreous. Fore wings light ochreous, mottled 

 with brown and black scales, costal edge evenly mottled with black, and 

 entire apical part of the wing sprinkled with sparse black scales, two 

 oblique, ill-defined and indistinct shades of light brown stretch across the 

 wing, one from the base, the other from the middle of costa. There are 

 six tufts of raised ochreous scales in two longitudinal rows, one through 

 the middle of the wing, the other below the fold. The central of the 

 latter tufts, which is found just before the tornus, is the largest of them, 

 and is terminated by and followed by intense black scales, the most con- 

 spicuous marking on the rather evenly mottled wing Abdomen ochreous. 

 Legs ochreous, mottled with black. 



Alar expanse, 11-12 mm. 



Habitat: Pennsylvania, District of Columbia, August. U. S. Nat. 

 xMus. Type No. 9796. 



The larvae feed in the base of the flowers of Evening Primrose 

 {Oenothera, sp.). The insect has long been in the Museum collection, and 

 was passed upon already in 1886 by Lord Walsinghain as Laverjia, 

 n. sp. 



It is nearest and quite similar to the other Oenothera-i^.editv, Mompha 

 breviviitella, Clemens, but lacks the longitudinal black streaks on the 

 fore wings, and is at once recognized by the black tornal patch. 



Mompha Engelella, new species. — Antennae dark purplish brown, 

 with silvery-white tips. Labial palpi golden yellow, tip of terminal joint 

 shaded with purple. Face, head and thorax dark purplish brown, 

 iridescent. Basal part of fore wings concolorous with thorax, and limited 

 outwardly by a narrow oblique fascia of bluish metallic scales, beginning 

 just before the middle of costa, and reaching the dorsal edge at basal 

 third. Apical fourth of the wing is of this same dark purple colour, and 

 the intervening middle part of the wing is bright golden. On this
