174 R. Newstead: On a Colleetion of Coceidae and Aleurodidae, of the Berlin Zoological Museum. 
Aleurodes filicicola n. sp. (Newstead). 
Puparium ellipsoidal, flat; without secretion of any kind; black, with a relatively 
broad margin of pale smoky-brown merging into the blackislı area. Dorsal hairs very 
slender, their position indicated by minute pale dots; of these there are for submedian 
rows and one submarginal, six rows in all. Margin with a few short slender spines; 
outer edge faintly and irregularly erenulated; inner edge of ventral „flange“ (fig. 12d) 
deeply and regularly crenulated, with the incissions deep and acute; caudal setae in 
a single pair. Vasiform orifice sub-pyriform; opereulum filling the posterior third; 
lingula with the basal portion bilobed and furnished with two, possibly four, short 
spines, not reaching beyond the orifice; the form of the operculum and especially 
also that of the lingula varies considerably, so that too much importance must not 
be attached to these characters.

This inseet belongs to that section of the genus in which the puparium is 
without waxy secretion of any kind; its distinguishing features also being the short 
ingula, and the minute dorsal hairs. A large percentage of the inseet were destroyed 
by a white fungus.

Larvae and ova only submitted for examination. T'he material is, therefore, 
insufficient for diagnostic purposes.

Material insufficient for diagnostic purposes. 
Many large black puparia of a species of Aleurodes were found in the glass 
ar containing the examples of Stietococcus dimorphus, Newst. The external fringe had 
been so completely destroyed in the alcohol as to render it quite impossible to 
determine the insect.
