38 CLASSIFICATION OF THE ALEYRODIDiE. m 
being provided, like the others, with a pulvillus, but only with a 
robust claw. 
These characteristics, I suppose, are constant in the species which 
form the group Aleurodicus, because I find them also in the species 
which I shall describe after this, of which there is no doubt that it 
is an authentic Aleurodicus, as it presents very distinctly all the 
specific characteristics which serve to keep distinct from others the 
forms composing this group. This will be confirmed, I repeat, by 
other observations which will be able to furnish a perfect diag- 
nostic characterization, notwithstanding the fact that by the absence 
of the adult forms the corresponding stage of the insect here de- 
scribed presents the other characteristics little conspicuous, so as 
to leave the author in doubt in regard to the place which ought to 
be assigned to the species. 
Length of body 1.520 mm.; width of body 1.000 mm.; length of 
waxy filaments exceeds 1 centimeter; thickness of waxy filaments 
0.080 mm. ; length of the conical process which supports the waxy 
filament 0.200 mm. 
Adult female. — The general shape of the body conforms to that 
of the congeneric species. The wings are well developed, the an- 
terior being much larger than the hind wings. They are covered 
with a very thin, whitish, waxy secretion. 
The forewings as well as the hind wings present numerous brown 
spots of varying size and with a contour more or less notched, as 
can be seen from figure 2, No. 8 [fig. 4, 8] . 
The legs are rather long, of medium thickness, subequal, the an- 
terior pair being shorter. The variability of the length of the legs 
is due chiefly to the difference in length which exists between all the 
joints of the tibia and the tarsus, while the coxa, the trochanter, and 
the femur in all three pairs of legs are of equal length. All the joints 
of the legs are furnished with cilia which, on the whole, are short 
and slender. Those inserted on the coxa are more delicate but more 
numerous, while those inserted on the tibia are more robust and 
shorter in length. The tibia near its distal apex presents also two 
pin-; of considerable size. The tarsus at its apex is provided with 
two long, robust claws, one of which at its internal margin is 
furnished with a tooth, the other being unarmed. Between the two 
claws there is an empodium in the shape of a foliate lamina in which 
the external marginal edge is furnished with numerous fine hairs. 
The hind end of the abdomen terminates in an ovipositor consisting 
of foui- pices the outside two of which present a dentate externa] 
margin. The last sternite shows a certain number of hairs system- 
atically arranged. (Fig 2, No. 11 [fig. -1, 11]).
