THE SCALE INSECT GENUS ASTEROLECANIUM 43 



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

 stout, 2 slender ; bases of antennae one-fifth length of antenna apart ; beak setae, 

 2 pairs apical, 1 pair basal ; spiracle with 1 trilocular (occasionally 1 quinque- 

 locular) 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 three-fifths as long as tarsus ; 7 pairs of submarginal 8-shaped pores, none 

 between antennae ; 8 pairs of submarginal minute setae, on abdomen and thorax, 

 4 pairs of submarginal larger setae at anterior end; 3 pairs of setae between 

 antennae and mouth parts. 



Apex of abdomen : Truncate or slightly concave ; setae, apical about 126 /* 

 long, interapical about 25 ix long, dorsal about 5.4 //. long, inner ventral 7.2 n 

 long, intermediate ventral 9 n long, outer ventral 10.8 /x long; anal ring with 6 

 setae 28-30 n long, and an inner row of 6 and an outer one of 14 pores ; ventral 

 surface of apex slightly sclerotized near margin. 



Data. — Redescribed from unmounted material, 1 mounted female, 

 and 22 mounted larvae on Cuius salviaefolius, Azazga, Kabylie, Al- 

 geria, A. Balachowsky, December 13, 1936. 



Material at hand has been placed as algeriense on the basis of com- 

 parison with Newstead's description. Although Newstead described 

 stages which he called "larva" and " 5 second stage," both descriptions 

 apparently referred to the larval stage. He stated that the second 

 and fourth segments of the antenna had each a single hair, and the 

 sixth one long and two shorter ; the second segment has two long setae, 

 and the sixth more than one long and two short setae. 



Although listed as a synonym of fimbriatum by Lindinger in 1912 

 (67, p. 360), algeriense is not a synonym of fimbriatum or of arabidis, 

 to which it is more closely related. The adult female is difficult to 

 differentiate from arabidis, but the dorsal 8-shaped pores are more 

 numerous than in most specimens of that species, and those between 

 the median groups and the body margin tend to be larger than those 

 in the same area in arabidis; the marginal quinquelocular pores are 

 interrupted for a slightly greater distance at the anterior end and 

 terminate a little farther from the apical setae than in arabidis. 

 Larvae of the two species differ distinctly, algeriense having one and 

 arabidis two pores near each spiracle. 



Asterolecanium amboinae, new species 



(Fig. 5, E-J; pi. 9, R) 



Habit. — Living on the lower surface of leaves. 



Test of female. — Distinctly longer than wide, posterior end narrowed, some- 

 what produced and upturned, margin sometimes indented by growth against 

 hairs on leaf; 1.25-1.35 mm. long, 0.6 wide; very slightly convex dorsally, flat 

 ventrally; pale yellow, transparent, very thin, slightly punctate; marginal and 

 dorsal filaments whitish, the latter fragmentary, but much longer than marginal, 

 present in submarginal area ; larval exit apparently elliptical, in margin. 



Adult female. — Shape similar to that of test, 1.25 mm. long, 0.5 wide. 



Margin : 8-shaped pores in a single row terminating around the length of apical 

 seta from setal bases, posterior pores 8 fi long and 5 wide, the others 9-10 /u long 

 and 5.4 wide, about a pore's width apart; quinquelocular pores in a single row 

 from opposite antennae to halfway between posterior spiracular pore bands and 

 the posterior pair of 8-shaped pores, as numerous as 8-shaped pores near ends of 

 row, and one and a half times as numerous as 8-shaped pores between, and tor a 

 short distance outside of, spiracular pore bands. 



Dorsal surface: 8-shapod pores in a submarginal row of 25. a few 12 ft bum 

 and 8 wide, but the majority 16 m long ami 10 wide: minute 8-shaped' pores 

 sparse; disk pores fairly numerous; tubular duets ;V2 ,u long; dorsal tubes 

 present. 



Ventral surface: Antenna short, with 2 setae longer than diameter of antenna ; 

 beak without setae; spiracle with bar fairly slender, with atrium slightly
