less. Shape circular, fiat dorsally but convex 
ventrally, i.e., top-shaped where it fits into a 
pit on the leaf. Bearing a thick dorsal plate of 
wax which covers the body except for the sub- 
margin, orifice, and caudal area. Margin crenu- 
late, anterior and posterior marginal setae pres- 
ent. Submarginal groove present, contouring the 
margin except caudally. Fourteen submarginal 
setae on each side, 5 anterior to thoracic tra- 
cheal pore and 9 posterior. Thoracic tracheal 
fold absent. Thoracic pore (Fig. lOe) flask- 
shaped, reaching mesally nearly to submarginal 
groove; walls thicksided with numerous thick- 
enings, 4 or 5 small teeth on lip of pore which 
is slightly concave. Cephalic, thoracic, and ab- 
dominal areas of dorsal disc covered with dense 
circular simple pores. Lateral arms of transverse 
moulting suture straight meeting in very obtuse 
angle medially. Abdominal area densely covered 
with circular simple pores 0.01 mm. diameter. 
Segments each with a single transverse row of 
pores. Only 7 segments apparent. Eighth ab- 
dominal setae longer than orifice, bases distant 
from rim, and level with anterior margin of 
orifice. Vasiform orifice (Fig. 10/) subcircular, 
0.04 mm. long, 0.037 mm. wide. Operculum fill- 
ing orifice. Lingula subparallel-sided, apex 
rounded. Anal furrow present between posterior 
end of vasiform orifice and caudal setae, the 
ridges conturing the posterior part of the orifice. 
Caudal setae subequal in length to submarginal 
setae, bases nearer to margin than to orifice and 
narrower than orifice. Abdominal tracheal fold 
and pore absent.
