42 CLASSIFICATION OF THE ALEYEODID^. 
Subgenera of Aleubodicus. 
I. Lingula of pupa case long, spatulate or conical, exserted; lingula of adult 
long, narrow, and included ; compound pores as illustrated in Plate 
III, fig. 2. 
A. Sides of pupa case flat, not deiiexed under ventral surface; vertex of 
adult rounded Subgen. Aleurodicus. 
B. Sides of pupa case deflexed under ventral surface; vertex of adult 
slightly bilobed Subgen. Lecanoideas. 
II. Lingula of pupa case short, conical, usually included ; lingula of adult broad, 
rounded, and exserted ; compound wax pores of pupa case as illus- 
trated in Plate XXVII, figure 3 Subgen. Hetaleurodicus. 
Subgenus ALEURODICUS n. subgen. 
Fore wings with the veins as given for the genus. Vertex rounded, 
antennae of seven segments, of which the third is the longest ; claspers 
of male long and narrow ; penis recurved, usually short ; pupa case 
flat, with a number of large compound wax pores of the type illus- 
trated in Plate III, figure 2, and sometimes a number of small re- 
duced ones. Vasiform orifice with a long, setose, spatulate exserted 
lingula, which is armed with four long spines. Size usually large. 
Type, anonce Morgan. 
Species oe Subgenus Aleurodicus. 
I. Pupa case with seven pairs of compound wax pores, one cephalic pair, and 
six abdominal pairs. 
A. All seven pairs of pores equally developed; size of pupa case 1.33 to 1.5 
mm. long by 0.83 to 1 mm. wide; pores broad and shallow; 
margin of case with irregular rectangular areas and a sub- 
marginal row of strong hairs; outline of case subelliptical to 
ovate; wings white, unmarked destructor. 
B. The two caudal pairs of wax pores and the cephalic pair more fully 
developed than the other four pairs, and with very long ((Mitral 
chitinized processes; size of pupa case 1 by 0.53 mm., shape 
elliptical; edge of case with large crenulatlons ; egg with the 
stalk much longer than the egg itself. Case raised on a vertical 
fringe of white wax and the dorsal surface covered with a plate 
of fused dirty white wax, through which the compound pores 
may be seen Jiolmcsii. 
C. The two caiidal pairs of pores are much smaller than the other fire 
pairs. 
1. Dorsal disk, as well as the submarginal area, covered with numerous 
Simple pores; compound pores very large ami well developed; 
margin of ease entire, with a row of stout hairs just within. 
Lingula long, with four very prominent hairs; operculum with
