Without dorsal secretion. 
Pupa-case yellow, broadly elliptical, convex, 1.15 by 0.83 mm. A 
short, more or Lees slanting, fringe all around of white wax, doubt- 
less homologous with vertical fringe. Vasiform orifice broadly 
ovate, lingula spatulate. Dorsum void of pores and papillae. In 
adults, wings with a distal dusky spot xpirxoides n. sp. (36) 
It has not been possible to indicate in the above table, the Alewrodrs 
ph(rtcmoides of Blanehard, reported from Chile, in 1840. The descrip- 
tion is meager, and based on the adult. In the Division of Entomology 
collection, are specimens of an Aleurodes, received through Professor 
Cockerell, from Mr. F. Lataste, Chile, under the name Alcurod^ 
plmhwoides Lataste. Possibly this is meant for Blanchard's />/m/<i- 
xwidi s. Until more information is obtained on this point, and pending 
the finding of Lataste's description, it may be well not to consider A. 
phalaroides Lataste, as a distinct species. 
1. Aleurodes abnormis n. sp. (Plate I, figures 1-3.) 
Pupa-case, — Size, about 0.7 by 0.55 mm.; dense black, and cleared 
only after prolonged boiling in KOH. Shape, subelliptical, varying 
somewhat in outline. There is no lateral fringe, in the ordinary sense. 
The pupa-case becomes at length comparatively thick, and the dorsal 
disk is larger than the ventral. The marginal rim of wax tubes is 
bent downward and inward to the ventral surface of case, thus con- 
necting, the ventral and dorsal disks by an inward slanting rim. From 
this reflexion of the marginal rim the lateral wax tubes open directly 
against the surface of leaf, and the white cottony exudation of wax 
appears at first sight as homologous to the vertical fringe of wax, or 
palisade by which, in many species, the pupa-case is elevated from 
surface of leaf. This exudation is light, and does not elevate the case 
to tiny extent from the leaf. On the reflexed marginal rim the flirt- 
ings of the wax tubes may be observed with varying distinctness up 
to the dorsal surface of case.. Dorsum void of exudation of any kind. 
In immature specimens dorsum is concave, and there is a furrow all 
around just within margin of dorsum, the rim being quite prominent 
as a raised boundary line. Case at length becomes moderately convex. 
There is a pair of setae on caudal end of case, and a pair just cephalad 
of gasiform orifice. Under hand lens the abdominal segments .appear 
moderately distinct, and the 4 straight suture, extending from third 
thoracic segment cephalad to margin of case, is quite distinct, and 
the margins on either side minutely sculptured. The vasiform orifice 
seen in boiled specimens is small, Bubcircular, with semielliptical 
operculum and small obscure lingula. 
Adult 9 .—Length, about 0.77 mm.; fore-wing, 0.89 by 0.36 mm.; 
hind tarsus, <>. 17 nun. ; hind tibia, 0.2fl nun. ( Jolor of body uniformly 
yellow, legs and antenna' paler. Eyes not quite divided, dorsal lobe
