one. In the third-stage male the anal ring has pores even though 

 these are absent in the larvae and adult females. 



Asterolecanium rubrocomatum is rather closely related to exiguum 

 and udagamae, but can be separated from these by the presence of 

 claws. 



Asterolecanium sabalis, new species 



(Fig. 61, A-E; pi. 5. G) 



Habit. — Living on both surfaces of leaves. 



Test of female. — Elongate elliptical, posterior end tapering slightly ; 1.5-1.75 

 mm. long, 0.5-0.6 wide ; slightly convex dorsally, sometimes with a faint longi- 

 tudinal median carina ; flat ventrally ; bright deep yellow, transparent, thin, 

 punctate ; marginal filaments cream color ; elliptical larval exit in margin. 



Adult female. — Elongate elliptical, posterior sixth tapering slightly ; 1.25-1.5 

 mm. long, 0.5 wide. 



Margin : 8-shaped pores in a single row that is briefly interrupted, usually 

 twice, near posterior end, and terminating one and one-half times a pore's length 

 from bases of apical setae, the pores 9 ^ long and 5 wide, less than a pore's 

 width apart on lateral margin, and slightly more than that distance apart an- 

 teriorly ; trilocular pores in a single row starting near antennae and ending 

 near anterior interruption in row of 8-shaped pores, as numerous as corre- 

 sponding 8-shaped pores at ends of row, two or three times as numerous as that 

 elsewhere. 



Dorsal surface : Minute 8-shaped and disk pores sparse ; tubular ducts absent 

 along median line, except near anterior margin, scattered elsewhere, 24 n long. 



Ventral surface: Antenna flat, with 3 setae slightly longer than diameter of 

 antenna; beak apparently without setae; spiracular bar expanded at inner end; 

 15-25 trilocular pores extending from spiracle to body margin in an irregularly 

 single row ; multilocular pores, with 10 loculi, in 3 complete and 3 or 4 inter- 

 rupted rows, the posterior row with 4-6 pores, the other complete rows each with 

 9-11, and each of the interrupted rows with 2, the total number 32-37 ; a group 

 of 8-15 dark-rimmed 8-shaped pores each side of mouth parts; submarginal 

 8-shaped pores in a single row terminating directly anterior to apical setae, about 

 one-third as numerous as marginal 8-shaped pores; apparently 7 pairs of sub- 

 marginal setae on abdomen, the posterior pair anterior to the penultimate pair 

 of marginal 8-shaped pores ; 3 pairs of setae in posterior complete row of multi- 

 locular pores, 2 or 3 in median row, and 1 pair in anterior row. 



Apex of abdomen: Lobes indicated; setae, apical 60 /x long, inner ventral and 

 outer ventral each about 3 n long; anal opening ventral, circular, its margin 

 sometimes faintly sclerotized. 



Larva. — Nearly elliptical, posterior end narrowed. 



Margin: Wih 28 8-shaped pores normally (sometimes only 27), the anterior 

 pair slightly larger than the others, axes of the posterior 8-11 pairs transverse, 

 of the others longitudinal ; usually with a minute seta close to each pore of the 

 posterior 3 pairs ; 3 pairs of setae at anterior end. 



Dorsal surface : 8-shaped pores in a submedian row of 4-10 (usually 8 or 9) 

 and a lateral row of 8 or 9, on each half of body, two-thirds as large as posterior 

 marginal pores: disk pores between lateral and marginal, and occasionally 1 

 between submedian and lateral 8-shaped pores. 



Ventral surface : Antenna 5-segmented ; antennal setae, T, ; IV, 1 ; V, 3 long, 

 2 stout, 2 fairly stout; antennal bases one-half length of antenna apart; beak 

 setae, 2 pairs apical, 1 pair basal ; spiracle with 1 trilocular and 1 quinquelocular 

 pore ; leg setae, coxa 2, femur 1 on inner margin near base, tarsus 1 each on 

 inner and outer margins : tibia one-half as long as tarsus ; 9 pairs of submarginal 

 8-shaped pores ; 10 pairs of submarginal minute setae, on abdomen, thorax, and 

 head ; 2 pairs of setae near antennae. 



Apex of abdomen : Lobes sometimes indicated ; setae, apical 45 n long, inter- 

 apical 5.4 w long, inner and outer ventral each 1 fi long; anal opening apical, 

 circular, its margin membranous. 



Test of male. — Elliptical, 1 mm. long, 0.5 wide; slightly convex dorsally, with a 

 faint longitudinal median carina ; flat ventrally; bright yellow, transparent, thin, 

 shiny ; marginal filaments rubbed off. 



Adult male. — 0.75 mm. long.
