a row 2-4 pores wide, terminating near anterior row of multilocular pores, the 

 rows broken up into groups so that there are 2-4 pores opposite some marginal 

 8-shaped pores and none opposite others ; 2 disk pores each in posterior and 

 penultimate rows of multilocular pores ; submarginal setae in a complete row 

 terminating 2 or 3 8-shaped pores from the posterior pair of marginal 8-shaped 

 pores ; 1 pair of setae in each row of multilocular pores and 1 pair anterior to 

 these pores. 



Apex of abdomen : Notch shallow ; setae, apical 80 n long, interapical 36-40 n 

 long, dorsal 24 /j, long, inner ventral 8 /^ long, intermediate ventral 6-9 n long, 

 outer ventral 12-16 fi long; anal ring with 6 setae 64—72 n long, and with an 

 inner row of 8 and an outer one of 22 pores, tending toward division on dorsal 

 side; ventral surface of apex rather heavily sclerotized around inner ventral 

 setae, surrounding area sclerotized in dentate rows. 



Larva. — Nearly elliptical, both ends slightly narrowed. 



Margin : With 28 8-shaped pores, the posterior 6 pairs slightly smaller than 

 the next 7, the anterior pair a little larger than any others, axes of the posterior 



6 pairs transverse, of the others longitudinal; a pair of minute selae close to 

 each of the posterior 4 pairs of pores ; 4 pairs of setae anteriorly. 



Dorsal surface : Disk pores in submarginal and lateral areas ; 1 pair of setae 

 in submedian area anteriorly. 



Ventral surface : Antennal setae, I, 2 ; IV, 1 ; V, 1 ; VI, 2 long, 2 stout, 3 fairly 

 stout, 2 slender (unusually short) ; antennal bases about one-fifth length of antenna 

 apart ; beak setae, 2 pairs apical, 1 pair basal ; spiracle with 1 quinquelocular pore ; 

 leg setae, coxa 4, femur 1 on inner margin near base and 1 each on inner and outer 

 margins near center, tarsus 2 on inner and 1 on outer margin ; tibia one-half as 

 long as tarsus ; 7 pairs of submarginal 8-shaped pores, none between antennae ; 



7 pairs of submarginal minute setae on abdomen, 4 pairs of submarginal larger 

 setae at anterior end ; 3 pairs of setae between antennae and mouth parts. 



Apex of abdomen : Notch shallow ; setae, apical 120 /j. long, interapical 32 /x 

 long, dorsal 8 n long, inner ventral 6-8 /jl long, intermediate ventral 12 /j- long, 

 outer ventral 16 /* long ; anal ring with 6 setae 28-32 fi long and with an inner 

 row of 6 and an outer one of 14 pores. 



Data. — Described from the following material collected by Ch. 

 Rungs and received from A. Balachowsky ; unmounted specimens, 

 4 mounted females, and 45 mounted larvae on Launea arborescens, 

 "Tagoud, Valley of the ould Draa, Sahara Morocco," February 1934, 

 No. 750, holotype and paratypes; unmounted specimens, 3 mounted 

 females, and 3 mounted larvae on Launea arborescens, "Oasis de Ferkla, 

 Sahara Morocco," May 10, 1934, paratypes. 



This species is closely related to arabidis, fimbriatum, nevadense, 

 and stentae. 



ASTEROLECANIUM LITSEAE Kuwana 



(Fig. 38, A-E; pi. 9, C) 



Described in 1916 (55, p. 149) on Litsea glauca from Matsudo in 

 Chiba-Ken, Japan. 



Habit. — Living on the lower surface of leaves. 



Test of female. — Longer than wide, 1.2-1.5 mm. long, 0.9^1 wide, posterior end 

 slightly produced ; flat dorsally, or very slightly convex, with a faint longitudi- 

 nal median carina, flat ventrally ; very pale yellow, transparent, very thin, shiny, 

 punctate; marginal and dorsal filaments very pale yellow, whitish, or slightly 

 pinkish, the latter scattered, and same length to nearly twice length of marginal ; 

 elliptical larval exit in margin. 



Adult female. — Similar to test in shape, 0.8-1.2 mm. long, 0.75 wide. 



Margin : 8-shaped pores in a single row terminating twice a pore's length from 

 bases of apical setae, posterior pores 9 n long and 6 wide, the others 10 ft long 

 and 8 wide, a pore's width to length apart ; quinquelocular pores in a single 

 row terminating near the posterior pair of 8-shaped pores, and slightly more nu- 

 merous than 8-shaped pores. 



Dorsal surface : 8-shaped pores in median, submedian, and submarginal 

 groups, 11-14 submarginal and 3-5 submedian groups on each half of body, each 

 with 1-4 pores, median group divided into 7-9 fairly definite, transverse rows,
