the larvK recorded by him as feeding in the bases of the flowers of 

 evening primrose. Winn (Lep. Quebec) states that it occurs at 

 Montreal, Canada, September lo, the food of the larvae being the 

 seed capsules of evening primrose. It is not recorded by Smith in 

 his " Insects of New Jersey," and this seems strange in view of the 

 fact that we have found this species to be generally distributed over 

 New Jersey, the larvae living in the flower buds and causing them to 

 swell conspicuously. 



Egg. — Length 0.42 mm. Width 0.26 mm. Oval, yellowish- white, 

 translucent, larva showing through transparent chorion which is 

 apparently smooth. 



Ftill Grown Larva. — Length 10 mm. Width 1.7 mm. Elongate, 

 cylindrical, tapering slightly anteriorly and more so posteriorly. 

 Ground color light yellow. All body segments broadly, transversely 

 banded with pink, this band being not so apparent on anterior seg- 

 ments because of it being more diffused. Pink coloration varies 

 considerably and in some specimens is barely visible so that the larva 

 has a light creamy-yellow appearance. Head brown, somewhat mot- 

 tled and variable in intensity, dark around the margins. Ocelli lat- 

 eral, six in number, grouped around a dark center. Head and each 

 body segment bears a few minute hairs, some of which are arranged 

 in a more or less transverse row. Head bears several long hairs. 

 Cervical shield brown, covering much of middle portion of dorsal 

 surface of prothorax, front margin straight, posterior margin 

 rounded, divided longitudinally in center. 



Pupa. — Length 5.5 mm. Width 1.6 mm. Elliptical, smooth, 

 chestnut-brown. 



Adult. — Mompha stellella. Busck's description follows: "An- 

 tennae unicolored, 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, mottled with brown and black scales, costal edge 

 evenly mottled with black and entire aprcal part of .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
