Watr.—Leaf-mining Insects of New Zealand. 683 
segments, occasionally as long as or slightly longer than body ; antennae 
narrow, segmented, extending beyond abdomen; forewin ngs occupy only 
about one-fourth of ventral aspect of pupa, and extend to junction of fifth 
and sixth segments. 
Dorsal aspect: Front possesses two well-developed setae, one on either 
first segment covered wings, absent in 9 and 10, those on 8 smaller and 
situated more ventrad than the rest; a pair of dorsal setae on every 
segment excepting last four, a long slender dorso-lateral seta on each 
segment below and behind spiracle, and a smaller lateral one below and 
in front of the spiracle in segments 2-6 inclusive; on upper part of 
dorsum of segments 2-8 inclusive is a narrow belt of two or three irregular 
series of short stout bristles directed caudad, and over remainder of dorsum

Dehiscence. (Plate 68, fig. 2.) 
Pupa extruded as far as seventh or eighth abdominal segment. Me ast 
splitting takes place dorsally along mid-line of vertex, prothorax, and m 
thorax, but not extending into metathorax. -The front, with mi эана 
portion of eyecaps, mandibles, maxillae, and labial palpi, becomes almost 
totally removed, being retained only by caudal extremities of maxillae.
