236 Teneina of the United States. 



As with the Cosmoptenjx, 1 hardly know whether this insect repre- 

 sents a new species, or is only a variety of some described one. The 

 orhanientation is almost equally like Haivorthana, equitella and impi- 

 gritella. 



LiTHOCOLLETis — L. Rileyella, n. sp. 



This is the nearest and only near ally of L. argintinotella, Clem., yet 

 made known in this country. It is indeed exceedingly close to it, but 

 It is darker saffron, has six instead of five costal streaks, which are 

 (as are also the four dorsal streaks) all dark margined internally and 

 are all very distinct, whilst in argintinotella, the fourth and fifth are 

 small and sometimes obsolete, and the autennse instead of being silvery 

 white, are dark ocherous, with brown annulations. As in argintinotella 

 the face and palpi are white, the vetex yellowish and white, and the 

 thorax and forewings are golden saffi-on. On each side of the thorax 

 just above the patagia, is a snow-white line continuous with the rather 

 wide and distinct snow-white median basal streak of the forewings; 

 which extends beyond the basal fourth and is unmargined. The first 

 costal streak is very oblique opposite the basal position of the first 

 dorsal streak, and is continued very distinctly along the costa to the 

 base, and after it leaves the costa is very faintly, dark margined above. 

 The second costal is less oblique, the third is still less so, the fourth 

 is a hook almost (or quite?) ; meeting the apex of the third dorsal, the 

 fifth is a short line pointing obliquely forward, and the sixth is a 

 small spot close to the apex, and just beyond the minute black cir- 

 cular apical spot ; the first dorsal streak is like that of argintinotella, 

 but is somewhat wider; it is placed about the basal third, is wide upon 

 the costa curving back along the middle of the wing to a point near 

 the apical third, and like all the other costal and dorsal streaks, it \b 

 strongly dark margined, internally its dark margin produced back- 

 wards along the middle of the wing till it joins the dark margin of the 

 second dorsal streak, which is distinct triangular with its dark mar- 

 gin produced beyond it ; the first dorsal streak recalls the similar 

 streak in Glyphipteryx exoptatella and G. Haworthana, but is wider on 

 the base. The third dorsal as above stated is opposite to, and almost 

 confluent with the fourth costal streak ; the fourth dorsal is small and 

 opposite to the minute apical spot : cilia yellowish with a brownish 

 wider marginal line on the base. Abdomen and tuft yellow: hind legs 

 yellowish silvery with the outer surface of the tarsi dark brown. De- 

 scribed from two specimens, received from Prof. Riley and Miss 

 Murtfeklt, from St. Louis, one captured, the other, labeled " tentiform 

 mine on under surface of red oak leaves, " al, ex. of one, \ inch, the 

 other ^ inch.
