AET. 17 MASKELL ASTEROLECANnisrAE MORRISOlSr 27.1 



specimens are included in the unmounted material of the species to 

 which has been assigned the lot No. 500, The redescription which 

 follows is based chiefly on supplementary mounts prepared from this 

 unmounted material. 



Adult female. — See Maskell and Froggatt references for descrip- 

 tions of test and of external appearance of insect ; body, as mounted, 

 elliptical, longer than wide in early adult to stout, nearly circular or 

 broader than long in mounted examples of old shriveled specimens, 

 length and width of early adult 1.5 and 1.2 mm. ; of old adult 1.6 

 and 1.8 mm.; derm membranous throughout; antennae fairly well 

 developed, normally 8 to 9 segmented, about 196/a long, the three 

 apical segments bearing stout sensory setae ; legs wanting ; spiracles 

 not unusual in shape, size, or position, marginal setae fairly stout, 

 with large bases, total length about lO/t, width of base 7/ji, not 

 numerous, not conspicuous, with two anterior spiracular spines, these 

 conspicuously differentiated in size, one about 70^, the other about 

 35/x, but with only a single posterior spine, this approximating the 

 larger anterior in size, about TO/x, and with only a single band of 

 disk pores leading from posterior spiracle to body margin, instead of 

 the two diverging bands usually present ; dorsal surface of body with 

 a very few relatively large, short, stout setae, about 9/x long, and so 

 approaching the marginal in size and appearance; ventral surface 

 with a submarginal row of moderately stout setae immediately adja- 

 cent to the marginal row and about as long as the dorsal, with a 

 pair of much larger setae anterior to the anal region, each about 90/* 

 long, and with a few slender, delicate setae scattered elsewhere, more 

 abundant in the genital region; 8-shaped pores of derm small, 

 numerous and rather uniformly distributed dorsally, with a loose 

 triple row along the body margin somewhat larger, largest at margin 

 immediately adjacent to the ends of the spiracular pore bands, ventral 

 submarginal area with still smaller 8-shaped pores, these apparently 

 lacking over the mid- ventral area ; tubular ducts large and numerous 

 dorsally, although not so abundant as the 8-shaped pores; with sev- 

 ,eral (up to seven) transverse segmental rows of multilocular disk 

 pores, each pore normally with 10-11 loculi, ventraUy on the abdo- 

 men; spiracular disk pores in a single band from each spiracle to 

 margin, each normally with five loculi ; with a few minute simple disk 

 pores ventrally near margin ; cribriform plates small but evident, not 

 minute and inconspicuous as in acacme, normally in two rows of four 

 each; anal area as in other species but with the upper half of each 

 plate distinctly imbricate-reticulate, the upper edge of each bearing 

 two moderately stout setae about 20)li long; anal ring narrow, bear- 

 ing eight setae ; apical seta relatively conspicuous, rather slender, but 

 llOli long.
