 Type.—l^o. 4949, U.S.N.M. 



Described from five specimens, bred Fel)ruary 10 to 20, 1900, from 

 material collected by Dr. Dyar, at Palm Beach, Florida. 



Egg is laid on underside of leaves of Erythrina herhacea, and the 

 mine begins on the upper side as a short serpentine track, but soon 

 l)roadens out in a large irregular blotch, often obliterating the early 

 part of the mine. Frass black, scattered. When full grown the larva 

 is 4.5 to 5 mm. long, cylindrical, somewhat flattened, tirst and second 

 thoracic segments enlarged, body tapering backward. Color white, 

 with light-brown mandibles and two small black lateral spots on tirst 

 thoracic segment. 



Pupates in ^'hammock" outside the mine on leaf in a glistening 

 white oblong cocoon spun under an equally showy white bridgework 

 of longitudinal silken bands. One leaf often contains several mines. 



LEUCOPTERA GUETTARDELLA, new species. 



Antenna yellowish silvery; eyecap shining silvery white. Palpi 

 absent. Head and thorax white. Forewing shining white, from 

 costal two-thirds to middle of dorsal margin an oblique, golden, nar- 

 row fascia, black margined externally; from same point on costa to 

 tornus is another similar golden fascia, also black margined externally, 

 together with the first forming a V turned upside down; parallel with 

 the latter fascia is a green costal str-eak, a little farther out toward 

 apex, and still nearer apex is a small golden spot. At extreme apex 

 is a small circular black dot and at tornus around the base of the second
