often 2-5 on one leaf, are oval, glistening white and very large in 

 proportion to the moth. 



The young larva eats into the leaf, forming a short, narrow, 

 serpentine track, which soon broadens out in a large irregular upper 

 blotchmine, often entirely obliterating the early part of the mine. 

 The mines show reddish brown on the upper side of the leaf and con- . 

 trast very conspicuously with the dark-green foliage. The black frass 

 is distributed irregularly in the mine, the inside of which is a dirty 

 domicile for such a dainty creature to issue from. The larva is, when 

 full grown, 5.5 mm. long moniliform, somewhat flattened and taper- 

 ing backwards ; first thoracic segments the broadest, nearly twice as 

 wide as the head. Head light brown, body dark, glossy-greenish with 

 two longitudinal black spots on first thoracic segment ; and legs normal. 

 Often two to five larvae are found within a common large mine. 

 Dr. Dyar has made the following notes : 



" Head flattened, subcircular, labium slightly projecting, clypeus band-shaped 

 but narrowed above, reaching vertex ; paraclypeal pieces large, broad, each nearly as 

 broad as the clypeus itself, narrowed above, reaching vertex and reducing each lobe 

 to about one-fourth of the surface of the head. Ocelli obsolescent, antennae rudi- 

 mentary Body moniliform, joints 2 and 3 large, 4 and 5 smaller, 6 to li larger, 12 

 and 13 tapering rapidly, 13 elongate, divided. Feet normal, thoracic ones small 

 abdominal short with a complete, broad ellipse of small, sparse, scarcely recurved 

 crochets ; those of joints 7 to 10 and 13 essentially alike. Whitish, no marks, no 

 shields, but a paired blackish patch in joint 2. Tubercles absent, set.^ very fine and 

 slender practically absent except laterally, iv and v in line remote, iv a trace dorsad ; 

 only iii and iv are at all well developel. On thorax the subprimaries lu and iv are 

 present."— (Harrison G. Dyar.) 



When fully grown the larva quits the mine through a moon-shaped 

 cut in the upper epidermis and spins a beautiful glistening white 

 brid-ework, consisting of two paralel broad flat silken bands each 

 about ID mm. long and 1.5 mm. wide, connected at the middle, 

 under which the spindle-shaped snow-white cocoon proper is made. 



Several overlapping generations are found during the summer m 

 this locality, the moth issuing from the middle of June to late in Sep- 

 tember. The insect over-winters as imago. Besides two Florida 

 species described by the writer only one other species of this genus is 

 described from this country, namely Leiicoptera {Cemiostoma) albella 

 Chambers, on poplar; but diligent rearing will disclose more unde- 

 scribed species, as I have taken others at light this summer. 



It will be seen from the delineation of the venation ^Plate IX,
