7. Aleurodicus minima ii. Bp. (Plate VI, figures 63-67.) 
Pupa-case. Size about 1.17 by 0.71 nun., subelliptical, many speci- 
mens are somewhat narrowed cephalad. Case usually widest across 
region of second abdominal segment. Color yellowish, varying to 
brownish. Empty Case semi-transparent, except for the irregular 
brown coloration on margin, and at the dorsal pores. Margins 
slightly crenulated, with very shallow indentures between the lateral 
wax tubes. There is do marginal rim. Just within the margin, all 
around, is a closely set row of short disk-like tubercles or papillae, 
from which is produced a fringe of almost straight, tapering, glassy 
waxen rods from one-third to one-half as long as pupa-case is w ide. 
On the more ((Mitral dorsal region a light mealy waxen exudation may 
occur. Pupa-case slightly raised from surface of leaf by vertical 
fringe of wax. which usually remains attached to leaf on removal of 
dried specimens. On the dorsum, nearer the margin than center, is a 
row on each side of seven round and well-defined compound pores. 
Considered transversely, these occur in pairs; a pair on cephalic seg- 
ment; a pair on me ta thorax; three pairs along the abdominal segments, 
and two pairs in the region latero-caudad of the vasiform orifice. The 
caudal pair is somewhat the largest, with the cephalic pair next in 
size; the rest are subequal. These pores, individually, consist of a 
cylindrical, brownish-colored rim with a central, white, rod-like struc- 
ture. On cephalic margin of case is a pair of seta' and a pair on the 
caudo-lateral region, a seta on each side. There is a pair of small, 
tubercled seta' jr t within caudal margin. Around the margin, just 
within the submarginal series of papillae, is a row of small tubercled 
seta', usually from 24 to 28 in all. 
Vasiform orifice elongate-cordate; about three-fourths as broad as 
long; cephalic margin straight, caudal end bluntly rounded. Oper- 
culum, subelliptical, cephalic margin straight, about one-third as long- 
as oitfice. Lingula usual, broad, extending quite to caudal end of 
orifice, hearing two pairs of setae distally. On ventral surface, rudi- 
mentary feet and antenna' quite distinct. 
Adult $ . — Length, about 0.80 mm.; fore-wing, 1.1 by 0.52 mm.; 
length of hind tarsus, 0.21 mm.; Length of hind tibia, 0.38 mm.; Length 
of hind femur. 0.26 mm. : color, -yellowish white, with dorsum of thorax 
brownish. Eyes reddish, undivided, though with a pronounced con- 
striction. Joint 1 of antenna' short, not one-half the length of second. 
Joint 2, narrow at base, truncate at distal end, widest centrally. Joint 
3 long, longer than remaining joints together, distal joint ending in 
an attenuated process, hearing a terminal seta. Anterior tarsus about 
three-fourths length of posterior. Distal tarsal joint of firsl pair legs 
two-thirds length of distal joint of mentum. Wings slightly clouded 
around margin and w ith a very dilute oblique transverse hand centrally: 
at fork of distal branch of vein i- a pronounced spot of brow nish-black
