NEW SPECIES OF TTXFJD MOTITS—UVSCK. 285 



Family ELACHISTlDyE. 



COSMOPTERYX Hubner. 

 COSMOPTERYX IPOMOEiE, new species. 



AntcniKv dark gTeenish brown with a thin, white, iong-itiidinal line 

 on basal half; the three last joints are white, the five following- ])lack, 

 and the next joint (ninth from apex) is white. Labial palpi, shining 

 greenish black. Head and thorax dark greenish brown, nearly black, 

 with one very faint central line white. Forewing unicolorous with 

 head and thorax. Beyond the middle is a broad, pale straw yellow 

 fascia, slanting from costa outwards. This is preceded I)}' two bright- 

 golden metallic spots, the costal one dark margined, and, on account 

 of the form of the fascia, nearer the base of wing than the dorsal one. 

 On the other side of the fascia is another dark-edged golden costal 

 spot, and right opposite, in the yellow fascia, a dorsal one; between 

 these the yellow fascia flows out in a bilobed process into the dark 

 apical part of the wing. 



In the basal half of the wing are three very faint, thin, white longi- 

 tudinal lines, all more or less interrupted, the central one l^eing the 

 most distinct, and this is continvied on the other side of the fascia to 

 apex as a more pronounced white streak. Cilia dark brown. Hind- 

 wing dark brown, with green reflections; cilia lighter. Abdomen 

 purplish ])lack above, each segment edged with silver; anal tuft sil- 

 very; underside silvery white. 



Posterior tibia black, with a longitudinal, winding, white line; tarsi 

 black with white tips. 



Alar expanse, 8 mm. 



Described from two specimens reared from Ipomcea leaves, collected 

 by Dr. Dyar at Palm Beach, Florida. 

 ' Type.—lSiO. 4943, U.S.N.M. 



The mines were found numerously, together with Bedell la minor 

 Busck (see p. 243), and is somewhat similar to these in appearance, 

 consisting of clear, irregular blotches; Init is distinguished from them 

 by short silk-lined galleries inside the mine, in which the larva retreats 

 when disturbed. 



Larva is, when j^oung, white with yellow head and dark e3"espots 

 and mandibles; when mature it measures about 7 mm., and has three 

 wine-red longitudinal stripes, one dorsal and two lateral, all rather 

 narrow. 



It pupates in an inconspicuous, matted, flat cocoon outside the mine. 



COSMOPTERYX NIGRAPUNCTELLA, new species. 



Antennie drab colored, l)asal half with a thin longitudinal white 

 line, lighter, nearl}^ white, toward tip. The last joint is black, and
