71 
cocoons. Specific parts examined under the microscope were boiled 
briefly in KOH and then mounted in glycerine. 
Body (Fig. 5). Length 7 mm; maximum width 2.5 mm. Stout, 
slightly curved, fusiform to subclavate, greatest width somewhat 
beyond middle ; pleural lobes prominent, broadly rounded, those on 
meso- and metathorax oblique and more protuberant; penultimate 
abdominal segment with small pleural lobe; anus ventral, preapical 
and directed ventrad, anal segment rounded smoothly beyond anus; 
integument clothed with abundant minute spinules and sparse setae 
confined mainly to dorsum and pleural lobes; pronotum, mesonotum 
and metanotum with transverse series of 12 or 13 setae along dorsal 
ridge which is free of spinules, thoracic pleural lobes without spinules 
but with 2 or 3 setae, longest seta on thorax about 58 /x; first 
abdominal tergite with transverse row of 10 setae, the longest 35 /x; 
other tergites without conspicuous setae; sternites uniformly and 
thoroughly clothed with minute spinules; spiracles (Fig. 6) small, 
weakly pigmented, posterior ones slightly smaller than anterior ones; 
thoracic spiracular atrium 55 fi in diameter, weakly lined with 
anastomosing non-spinose ridges to form irregular polygons, opening 
into atrium surrounded by circular, non-sculptured area, entrance 
to subatrium simple and unarmed. 
Head (Fig. 7). Height .80 mm, excluding labrum; width .82 
mm. Coronal suture and parietal bands apparently lacking; front 
with two oval longitudinal impressions between antennal orbits; 
epistomal suture indistinct, indicated by a weak transverse impres- 
sion; antennal orbits subcircular, 45-50 /x in diameter, antennal 
papillae lacking, three sensilla in equilateral triangle arising from 
membrane at lateral margin of orbit. Setae on head numerous, 40 
of them distributed rather uniformly on sides and top and above 
bases of mandibles, only 4 setae on frons between antennal orbits, 
the longest 49 /x; clypeus (Fig. 8) with transverse row of 4 setae 
and basal transverse series of 7 or 8 minute “sensory” convexities ; 
head weakly pigmented except for anterior tentorial arms and 
mandibles. 
Mouthparts. Labrum (Fig. 8) .39 mm wide, truncate, with about 
18 setae 28 n long, distributed laterally and anteriorly, several 
smaller setae extending from apical margin medially; apical margin 
bristly except in center; apex of oral surface with median pair of 
minute sensory pegs arising from circular pores; epipharynx papillose 
on basal lateral areas but spinulose elsewhere, center with stout, 
somewhat raised spinules arranged in semicircular pattern; apical
