320 TRANS. ST. LOUIS ACAD. SCIENCE. 



Described from two specimens bred from galls, of the usual 

 Lepidopterous character, on the commoner Western Sunflower 

 in Texas, Aug. 12 and 17, 1873, 



This must closely resemble Steganoptycha variana Clem, and 

 St. lagopana Walsm., but I refer it to the genus Semasia at Prof. 

 Fernald's suggestion. 



Grapholitha GALL^-SALiciANA, n. sp. — r?. Expanse 1 1 mm. White, 

 the primaries blackish on terminal third, the secondaries graj'. Head 

 white, the antennae with a black line beneath. Thorax white : primaries 

 white, tinged with ochraceous along the costabejond the middle and spot- 

 ted with grajish-brown on costa, and, more particularly, towards the inner 

 margin ; the space included between the apical angle, the anal angle, and 

 the middle of the inner margin, fuscous, ocellated spot silvery tinged with 

 lavender, enclosing a gray and one or two jet black spots and preceded by a 

 black transverse spot; a silvery streak from the costa to just beneath the 

 apex, and a shorter parallel silvery streak extending from the middle of the 

 cost*; fringes fuscous with a silvery reflection, preceded by a black mar- 

 ginal line: secondaries iw^coxx?,, fringes silvery : under surfaces fuscous, 

 markings of primaries faintly repeated : legs silvery-white. Abdomett 

 fuscous above, silvery-white beneath, excepting the apical joint. 



Described from two specimens bred June 17, 1873, from galls 

 on willow twigs, St. Louis, Mo. 



At once distinguished from the European campoliliana by its 

 pure silvery or satiny-white coloration imtinged with yellow. Its 

 general color is that of the European Spilonota roborana* Schiff', 

 but it is much smaller and is very differently marked. 



Grapholitha OLIVACEANA, n. s. — (S' • Expanse 18 mm. Thorax oliva- 

 ceous : primaries olivaceous with a pale ochraceous tinge ; an oblique 

 streak from the middle of the costa connecting with a broad, somewhat 

 wavy stripe which extends through the middle of the wing to just before 

 the apex; two spots on inner border, one near base, the other (which is 

 larger and more elongate) toward anal angle, and some costal and apical 

 streaks brown-olivaceous; ocellated spot silvery, the^ centre ochraceous 

 with two black stripes ; a silvery streak extending obliquely from the costa 

 to the posterior margin; fringes ochraceous, tinged with fuscous at apex : 

 secondaries gray, fuscous towards tip ; fringes white, dusky at base : under 

 surface of primaries fuscous; the fringes, except at apex, and some costal 

 spots ochraceous ; secondaries gray. 



Described from one specimen from Illinois (J. R. Muhleman). 



* This is, according to Staudinger & Wocke's catalogue, synonymous with cynosbana 

 Fabr. described in 1775; also with Hiibner's aquana. It Is, beyond much doubt, the same 

 as Hedya scudderiana Clem., Euryptychia saligneatia Clem, and Pcedisca affusana Zell.
