pores ; four pairs on abdominal segments and one pair on cephalic region. 

 Cephalad of vasiform orifice is a pair of minute bristles. Vasiform orifice 

 elongate cordate (Fig. 3), about 0.09 mm. wide at base, and about o.i mm. 

 long from base of operculum to tip of lingula ; cephalic margin straight, 

 caudal and evenly rounded. Operculum subelliptical nearly one-half as 

 long as orifice. Lingula broad, extending well beyond caudal end of 

 orifice, on distal fourth which usually lies beyond caudal end of orifice 

 with two pairs of comparatively long set^. Rudimentary legs and antennae 

 as usual. 



From wax pores on dorsum, there may be frequently seen protruding 

 white glistening waxen rods which frequently break ofi" and fall about the 

 pupae as in P. perseœ. The dorsal surface of case usually becomes, 

 especially towards maturity, well dusted with a thin coating of white 

 secretions, and at times a very narrow, downwardly directed marginal 

 fringe may be seen outside the vertical fringe. 



Adult. — Length, c? , about i.io mm. Forewing, 9? i-39 i^i»""- by 

 0.62 mm.; length hi?id femur, 0.26 mm. Length hind tibia, 0,35 mm.; 

 length hind tarsi, 0.18 mm.; length claws, 0.08 mm.; ? proportionately 

 larger. Yellow, covered with whitish waxen secretions ; eyes red, not 

 divided, but distinctly constricted. A line extending along side of head, 

 interrupted by upper portion of compound eye, the lateral callosities of 

 prothorax, indistinct traces along suture of proximal segments of abdo- 

 men, and portions of vasiform orifice, all blackish. Wings beautifully 

 irridescent, with deep violescent reflections, a small prominent round 

 brownish spot about 0.06 mm. in diameter (Fig. 4) on each fore and hind 

 wing just behind the posterior distal branch of vein, usually enveloping 

 vein but never filling the angle between veins as shown in A. mifuos 

 (Tech. Bull. 8, Div. Ent., Dept. Agric, PI. VI, Fig. 6), wings otherwise 

 unmarked. Antennae (Fig. 5) seven jointed, the comparative lengths of 

 the various segments as follows : 



Segments -^, -|-, ^, -i-, ^, ^, ^ 



Segments 3 to 7 show usual corrugations ; segment 7 with constriction 

 on distal half at which point is borne a distinct bristle.
