tunnel. At margin of leaf a narrow slit is prepared by larva prior to 
pupating. This slit is 2-3 mm. long and is em d slightly on under-surface 
of leaf. Tunnel is about 1 cm. in length and 3-4 mm. in diameter; the 
slit at its termination is not protected by silk but remains naturally 
closed. Frequently the leaves containing the cocoons wither and fall to 
the ground. The cocoon proper is about lcm. in length and posu 
is closely invested with frass-granules; a slight curtain of silk se 
anterior end from tunnel: In dead leaves containing cocoons, t тын а 
their tunnels ean readily be detected from. the exterior on both aspects 
of the leaf since the surrounding cuticle becomes shrunken and so анн 
them in relief. 
The Pupa. (Plate 30, figs. 5-7.) 
Pupa small but stoutly built, bluntly rounded cephalad, abdominal 
segments becoming attenuated caudad and terminating in a bluntly-poin 
cremaster. Lateral wing-margins relatively straight and parallel, ventral 
profile of thoracic —Á" well rounded, most prominent at level of 
second abdominal segment. 
Head—front situated more dorsad than ventrad, possessing a pair of 
short dorsal setae; vertex not very distinctly defined ; clypeus possessing 
pairs of minute setae as shown in Plate 30, fig. 5 ; labrum with a slight 
tendency to be bilobular; eye but little covered by antenna ; mandibular 
area relatively large and clearly defined; maxillary palpi short, situated 
caudad to eye and occupying short interspace above first leg between antenna 
and maxilla; labial palpi short and narrow ; maxillae broad above but 
constricted caudad, about twice as long as labial palpi ; antennae of about 
equal width throughout, not markedly segmented, do not extend beyond 
second legs in either sex, and are slightly longer in male than in female ; 
first legs short and stout and about half vaen of second, their caudal 
extremities separated by second coxae; between maxillae and first legs, 
but not extending beyond the latter, lie the коа of first legs ; second 
legs have a narrow strip above, are widest in mid-third, and, meeting in 
mid-line, lie closely adjacent in their caudal third, terminating about 
central point of pupa ; forewings extend as far caudad as fifth abdominal 
segment, below second legs they are separated in mid-line by a small 
strip of hindwings, appearing from beneath which are the caudal extremities 
of hindwing appears caudad to fore rothorax narrow, restricted 
in mid-dorsal region, and somewhat expanded laterad ; mesothorax with 
distinct mid-dorsal suture berets also into metathorax. Beyon 
a ien ca microscopical roughness ae pilini there is no sculpturing. Spiracles 
mall, circular, and slightly elevated, those of first a e 
omo by hindwings. Abdominal segments 2-8 inclusive possess tw 
nrbe: rows of dorsal fme anterior row cds slightly waved ud 
possessing a single line of small stout spines, posterior row gri ini 
extends Slightly farther ted than anterior, and its spines are 
minute and more numerous ; in second segment anterior row is ism ону 
developed, whereas as posterior row is most poorly developed in segment 8 ; 
row is present on segment 9 in male only and is pend developed. 
Cremaster flattened dorso-ventrally and bluntly rounded at apex, bears 
a small seriés of 6-8 slender hooklets, mostly situated ventrad. Genital 
rture apparently situated on segment 8 in female and on segment 9 in 
иа, well developed ; anal aperture well marked on segment 10
