densely mottled with purple pigment, leaving a straight, pale 

 dorsal line. Tubercles small, black; setae long, pale, dusky. 

 Feet normal, short ; thoracic ones dusky. Tubercles a little ele 

 vated. 



Antispila eugeniella Busck. The larva? are leaf miners in 

 Eugenia (probably E. procera). The mine starts in the sub 

 stance of the leaf, rapidly widens to a blotch, and finally the larva 

 cuts out a case, slightly constricted centrally. The larva is rather 

 short and thick, not moniliform, colorless, the head retracted api- 

 cally, dark ; a dark spot behind it. 



Cosmopteryx ipomcece Busck. The larva? are leaf miners in 

 " morning glory " (Ipomoaa sp.). The mine is an irregular series 

 of blotches and lobes, usually elongate and several partly joined ; 

 taking all the parenchyma between the two epidermes, the skin 

 strengthened by web, so that the surface is wrinkly. Frass partly 

 ejected, held to the leaf by a close web. 



Penultimate stage. Head flattened, rounded, quadrate, clypeus rounded 

 above; greenish, brown on the margin, eye black, jaws brown; width .4 

 mm. Body flattened, subventral fold prominent ; abdominal feet on joints 

 7 to 10 short, rather broad, all alike and equally remotely spaced, the 

 crochets rather numerous in an ellipse; anal feet approximate, crochets in 

 a line. Thoracic feet small, curved. Segments 2-annulate, the segmental 

 incisures marked, both these and the annulet incisures less opaque than 

 the body. A narrow longitudinal, lateral, transparent crease, interrupted 

 by the incisures. Venter 3-annulate; subventral fold double on joints 5 

 to u, notcrossing the annulets; joints 12 and 13 tapering. Cervical shield 

 large, flattened, semicircular, hard, but concolorous ; anal plate as large as 

 the segment but actually small. Translucent whitish, alimentary canal 

 green; rf glands in joint 9 large, annulate, showing four segments. A 

 group of setae before the leg (vii), a tubercle with very minute, rudimentary 

 setae near center of lower subventral fold (vi), two setae and tubercles close 

 together in anterior part of upper subventral fold a little before spiracle 

 (iv -(- vjjthe anterior one very small; spiracle round, iii above and before 

 it, i and ii nearly obsolete, showing as slight scars. Seta iv is the only 

 distinct hair; iii and v are present on thorax. Skin finely reticular sha- 

 greened. 



Last stage. Head flat, mouth projecting, eye black, mouth brown ; width 

 .6 mm. Body and head whitish, a broad dorsal and lateral dark red band 

 on joints 2 to 13 and a faint narrow one on the subventral fold in the center 

 of the body. Otherwise as before. Cervical shield semicircular, the dor 

 sal red stripe staining it posteriori v. Lateral stripe with minute pale dots. 

 Setae moderate, pale.
