ond, a more dorsal exudation, composed of three thick, inward, and, at 
the tip, downward-curving columns. These occur in a triangle, one 
on each side and one at end. These columns of white wax are about 
as high as pupa-case is wide. The pupa-case is almost obscured by 
this exudation, when viewed from above. There is a short vertical 
fringe elevating the case somewhat from the surface of leaf. On the 
dorsum are 5 pairs of cup-shaped compound pores, four pairs on 
caudal third of case, and the fifth pair on cephalic segment, one near 
each cephalo-lateral margin of case. The margin or rim of each cup 
is thickened, and from within the cup there arises a rather large fluted 
cylindrical tube, extending upward, about one-half its length beyond 
rim of cup. Within tube at base is a short conical elevation. The 
entire structure is brownish in color. Dorsum void of well-developed 
sete: save a pair just within caudal margin. <A pair of minute sete 
occur on margin, near caudal end of case. There is, however, just 
within margin of case, all around a sparsely set row of minute, brown- 
ish colored, tubercled setz. Vasiform orifice subcordate, about as 
long as wide, cephalic margin straight, coinciding with cephalic mar- 
gin of operculum. Operculum subrectangular, the lateral margins 
somewhat rounded; considerably wider than long, and with caudal 
margin almost straight. Lingula relatively large, particularly distally, 
where it becomes broadly spatulate; longer than orifice, and bearing 
distally two pairs of sete, the smaller pair proximad. Abdominal 
segments moderately distinct. Rudimentary feet and antenne very 
evident. 
Adult.—The following note is by Mr. Pergande, made at the time 
of receiving the material at the Division of Entomology at Washing- 
ton: ‘‘ Wings of insect, of which one was found, transparent, color- 
less, without any marking, and they are covered with a white secretion, 
which gives them a milk-white appearance. The body is yellow, 
shghtly reddish toward the tip of abdomen. Eyes dark brown.” 
This specimen, mounted on a tag, had, unfortunately, become detached 
before it came into the writer’s hands, but from the general structure 
of the pupa-case, particularly the vasiform orifice, and in the presence 
of the dorsal cup-shaped compound pores, it will probably prove to 
be an Aleurodicus.
