Asterolecanium parvum, new species 



(Fig. 48, A-G; pi. 9, BB) 



Habit. — Living on the lower surface of leaves. 



Test of female. — Virtually circular, 0.6 mm. in diameter ; strongly convex 

 dorsally, sides nearly vertical, top nearly flat, with a low, fairly wide longitudinal 

 median carina, a curved submarginal carina, a slight furrow between the carinae, 

 and with faint transverse striations across median carina; flat ventrally; green- 

 ish yellow, transparent, thin, shiny ; marginal filaments fragmentary, apparently 

 same color as test, dorsal filaments broken off, apparently around 17 in number 

 placed at fairly uniform intervals in submarginal area, and 1 or 2 in submedian 

 or lateral area ; elliptical larval exit in dorsal surface at margin. 



Adult female. — Nearly circular. 0.5 mm. in diameter, posterior end produced. 



Margin : 8-shaped pores in a single row terminating slightly more than length 

 of an apical seta from bases of setae, 5.4-6 m long and 3.6 wide, usually two to 

 four (sometimes as much as eight) times a pore's length apart; quinquelocular 

 pores in a single row terminating at the posterior pair of 8-shaped pores, or with 

 1 beyond, usually 1 near each 8-shaped pore when the latter are twice a pore's 

 length apart, and at about the same intervals where 8-shaped pores are farther 

 apart. 



Dorsal surface : 8-shaped pores placed at fairly uniform intervals in sub- 

 marginal area and a few in lateral area, the total being approximately 19, most 

 of the pores 9 y. long and 7.2 wide, with only 1 or 2 slightly smaller than that; 

 minute 8-shaped and disk pores fairly sparse ; tubular ducts 12 n long ; dorsal tubes 

 present. 



Ventral surface : Antenna a circular disk, with 2 setae slightly longer than 

 diameter of antenna ; beak without setae ; spiracular bar rather slender ; a single 

 row of 5-10 quinquelocular pores extending from spiracle to body margin ; 2 or 3 

 dark-rimmed 8-shaped pores each side of beak, a few in a single row in lateral 

 area, and a few in 2 transverse rows anterior to genital opening ; submarginal 

 8-shaped pores in a single row terminating near the posterior pair of marginal 

 8-shaped pores, the intervals between them twice the length of a marginal 8-shaped 

 pore; 5 pairs of submarginal setae on abdomen, the posterior pair at base 

 of produced part of abdomen ; 1 rair of setae posterior to genital opening, 1 pair 

 anterior to opening, and 1 pair anterior to those. 



Apex of abdomen : Setae, apical 56 m long, interapical 7.2 fi long, inner ventral 

 3.6 n long, outer ventral 4.5 n long; anal ring with 6 setae 23.4-26 fi long and with 

 an inner row of 6 and an outer one of 12 pores ; ventral surface of apex sclerotized 

 and rugose.
