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 lifth pair on cephalic segment, one m ar 
each cephalo-lateral margin of ease. The margin or rim of each cup 
is thickened, and from within the cup then 4 arises a rather large fluted 
cvlindrical 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 
setae save a pair just within caudal margin. A pair of minute setae 
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 seta3. Vasiform orifice subcordate, about as 
long as wide, cephalic margin straight, coinciding with cephalic- mar- 
gin of operculum. Operculum sub rectangular, the lateral margins 
somewhat rounded; considerably wider than long, and w ith caudal 
margin almost straight. Lingula relatively large, particularly distally, 
where it becomes broadly spatula te; longer than orifice, and bearing 
distally two pairs of setae, the smaller pair proximad. Abdominal 
segments moderately distinct. Rudimentary feet and antennae 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 airy marking, and they are covered with a white secretion, 
which gives them a milk-white appearance. The body is yellow, 
slightly reddish toward the tip of abdomen. Kvos 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-ease, particularly the vasiform orifice, and in the presence 
of the dorsal cup-shaped compound pores, it will probably prove to 
be an Alturodivus.
