AKT. 17 MASKELL ASTEROLECANnNAE MORRISON 29 



present but poorly and faintly developed, elongate cones with the 

 joints indistinctly, and claw poorly developed; beak short conical, 

 1-segmented; marginal setae rather short and stiff, each perhaps 

 I7ia long, but not stout, few in number, and accompanied by a few 

 somewhat smaller ventral submarginal setae; the two anterior 

 spiracular spines placed together, at most only somewhat unequal 

 in length, the longer about 43/^, posterior two on each side widely 

 separated, approximately equal in size, about 38ju, long; dorsal and 

 ventral surfaces with a few tiny, slender setae, these longer below 

 and most numerous around genital opening, the pair of much elon- 

 gated slender setae usually found ventrally just anterior to the anal 

 complex wanting or much reduced in size ; with small 8-shaped pores 

 scattered rather thickly and uniformly over the dorsal surface, 

 with definitely but not conspicuously larger 8-shaped pores in one 

 longitudinal and one transverse band dorsally forming a distinct 

 cross, in a submarginal row joined at intervals to the margin and 

 in a band along the margin, most of these larger pores somewhat 

 invaginated; this arrangement most obvious in early adult females, 

 rather obscured in the fully matured examples; tubular ducts elon- 

 gate, slender, numerous, more abundant towards margin; multiloc- 

 ular disk pores present in eight transverse rows on the ventral ab- 

 dominal segments, the anterior ones only a single pore wide, the 

 posterior ones fairly broad bands, these mostly with 10 loculi; 

 spiracular disk pores normally quinquelocular, those at margin dis- 

 tinctly larger than those near spiracle, the anterior band fairly wide, 

 the posterior split, the halves running diagonally to each spiracular 

 spine; tiny simple pores widely but sparsely distributed over the 

 dorsum and at margin, apparently wanting ventrally; cribriform 

 plates small and inconspicuous, resembling those of acaciae, nor- 

 mally in two rows of four each; anal area not peculiar, the plates 

 heavily wrinkled and ridged but not areolate, with two stout setae 

 near to but not on the upper margin of each, these about 14/t long, 

 anal ring narrow, with 10 somewhat swollen setae with delicately 

 produced tips, apical seta not differentiated from marginal, not 

 very stout, short, about 14/a long. 



Preadult female.— In general much as in adult, but less developed; 

 amply figured in the illustrations accompanying the paper, so not 

 described. 



Larva. — Elliptical, length as mounted 430/x, width 215/;i; anten- 

 nae 6-segmented, the apical longest, the three apical bearing stouter 

 sensory setae, total length about 165/^; posterior spiracular spines 

 relatively inconspicuous, other structures as shown in figures ; length 

 of largest spira(?ular spine about 8/x; anal plates faintly wrinkled but 

 not areolate.
