Apex of abdomen : Notch present ; setae, apical 65 fi long, interapical usually 



6 fi long, dorsal 2 n long, inner ventral 5.4 n long, outer ventral 5.4 /x long ; anal 

 ring with 6 setae 16.2 /x long and with an inner row of 6 and an outer one of 

 apparently 12 pores, divided on dorsal side and tending toward division on 

 ventral side ; ventral surface with a sclerotized, irregularly elongate area anterior 

 to base of each apical seta, median area faintly sclerotized in dentate rows. 



Data. — Redescribed from two tests, two mounted females (apex of 

 abdomen missing in one), and seven mounted larvae on Samolus 

 repens, Warrnambool, Victoria, Australia, November 1914, from E. E. 

 Green, type. 



Closely resembling stypheliae, but with many more marginal quin- 

 quelocular pores, with the tubular ducts 32 instead of 28 //, long, with 



7 to 11 pores in the atrium of each spiracle, and with 116 multilocular 

 pores. The larvae of the two species exhibit only minor differences. 



Asterolecanium nevadense Balachowsky 



(Fig. 44, A-F; pi. 4, D) 



Described in 1935 (-5, pp. 239-21$). 



Habit. — Living on stems, leaf petioles, and leaves. 



Test of female. — About 2 mm. long and 1.5 wide ; posterior end produced and 

 turned straight up, or hooked with tip nearly reaching dorsum of test ; strongly 

 convex dorsally, flat or concave ventrally ; pale whitish yellow, transparent to 

 translucent, rather thick, smooth, shiny ; marginal and dorsal filaments whitish, 

 the latter in an inconspicuous tuft along median line and scattered to margin, 

 the median filaments same length as marginal filaments, the others shorter ; 

 larval exit narrow elliptical, in margin. 



Adult female. — Somewhat ovoid, posterior end slightly produced; 1.7-1.9 mm. 

 long, 1-1.3 wide. 



Margin : 8-shaped pores in an irregularly double and single row terminating 

 around twice length of pore from bases of apical setae, irregularly or regularly 

 double from anterior end to slightly beyond posterior spiracular pore bands 

 and usually single from there to end of row, the pores usually alternate rather 

 than opposite when row is double, the intervals between them varying from 

 the width to the length of a pore, and the space between the rows about equal 

 to the width of a pore, individual pores measuring around 12 /x long and 8 wide; 

 quinquelocular pores in a single row interrupted for 40-50 8-shaped pores at 

 anterior end and terminating at about the twentieth pore from the ends of the 

 row of 8-shaped pores, about 1 quinquelocular pore to 1 8-shaped pore of nearer 

 row; disk pores dorsad of 8-shaped and ventrad of quinquelocular pores, each 

 row terminating near apical setae, the pores irregularly spaced, for the most 

 part about half as numerous as corresponding 8-shaped pores. 



Dorsal surface : 8-shaped pores in 5 or 6 groups in median area and dis- 

 tributed from these groups to margin, the median groups arranged transversely, 

 the other pores tending toward arrangement in transverse rows, the pores vary- 

 ing in size, those of the posterior 2 groups usually 10 /x long and 7 wide, the 

 majority of pores making up the other groups 12 /x long and 8 wide, most of 

 the scattered pores 9^10 n long and 6 wide ; minute 8-shaped pores absent ; disk 

 pores numerous ; tubular ducts 40 /x long. 



Ventral surface: Antenna a roughly circular area, with 2 setae slightly longer 

 and 3-6 usually much shorter than diameter of antenna ; beak with 2 pairs of 

 setae ; spiracle with bar very broad, with a sclerotized subcircular area around 

 opening, 4-6 quinquelocular pores in sclerotized area and 20-30 (usually 20-25) 

 extending to body margin in an irregularly double or triple row ; multilocular 

 pores in 3 complete rows near genital opening and 1 interrupted row anterior 

 to posterior spiracles, the posterior row with 8-12 pores, penultimate with 

 14-19, anterior complete with 7-11, interrupted row with 3-8, or a total of 41-43,. 

 majority of pores of complete rows with 8-11 loculi, those near spiracles occa- 

 sionally with only 5 loculi ; 5-10 dark-rimmed 8-shaped pores each side of beak, 

 a few scattered anterior to mouth parts, and a few posterior to beak in median 

 area arranged roughly in 4-6 transverse rows; submarginal 8-shaped pores in 

 an irregularly single to triple or rarely quadruple row terminating near a trans- 

 verse line drawn through the twenty-fifth from the posterior pair of marginal
