ALEURODICUS (lECANOIDEUS) GIGANTEUS. 71 



There is also a copious secretion of minute cottony wax threads, 

 from a broad submarginal zone or band of small simple pores com- 

 pletely around the case. From the margin or edge of the case there 

 is a secretion from the tubular wax pores (PI. XXIV, fig. 6) which 

 extends downward, more or less, under the pupa case in "the form 

 of an amorphous wax plate. The color is brownish to very dark 

 brown. Some specimens, however, have a distinctly reddish color, 

 though such individuals are comparatively few. The empty case is 

 ver}^ light brown, without distinctive color markings. 

 I The dorsum and margin of case are without spines. On each 

 side of the abdominal region are four compound wax pores (PL 

 XXIV, fig. 5) and a pair of similar though smaller pores occurs 

 on the cephalic end of case. The two pairs of small compound pores 

 present on the caudal end of the case, in many members of the genus, 

 are absent in this species. 



Vasiform orifice (PI. XXIV, fig. 4) subcordate, considerably 

 wider than long. Operculum about twice as wide as long, the basal 

 corners rounded, the caudal margin somewhat concave. 



Lingula large, exserted, spatulate in shape, bearing toward distal 

 end two pairs of spines. On ventral surface, legs and antennae 

 very evident; basal segment of leg large, subglobose. Distal seg- 

 ment of leg longer than basal, finger-like, ending in a single curved 

 claw. 



Adult female. — Length from head to tip of abdomen about 2.75 

 mm. ; length of forewing 3.50 to 3.75 mm. ; width 1.70 to 1.75 mm. 

 (Pl» XXIV, figs. 7 and 8); length of hind tibia about 1.23 mm.; 

 length of basal segment of tarsus 0.32 mm. ; length of distal segment 

 0.16 mm. 



Color of body and head light brownish, the legs and antennae 

 paler; wings white, without markings*, more or less dusted with 

 powdery wax. Ventral surface of body of the insect with light 

 flocculent wax apparently secreted from the abdomen. Some leaves 

 show paths or trails of white wax, evidently made by the adults 

 during the course of their movements (see PI. XXV). Ej^es of the 

 usual constricted form. Antenna? about 1 mm. in length; segments I 

 and II about equal in length to segment VI; segments VI and VII 

 suJIicqual ; segment III about one-sixth shorter than segments IV to 

 VII, inclusive (PI. XXIV, figs. 9-12). 



Male. — Having the general appearance of the female. Genital 

 valves long and slender, penis short and curved near distal end. 



7'ypc. — No. 14767, U. S. National Museum. Described from abun- 

 dant material of eggs and pupa^ on leaves, and adults on card points, 

 and all of these stages in balsam mounts.
