anterior ones, all practically same size as marginal pores of same segments ; 

 disk pores between submedian and lateral, and between lateral and marginal, 

 8-shaped pores. 



Ventral surface : Antennal setae, I, apparently 1 ; IV, 1 ; V, 1 ; VI, all broken, 

 but at least 7 of good size ; antennal bases apparently lengtb of antenna apart ; 

 beak setae, 2 pairs apical, 1 pair basal ; spiracle witb 2 quinquelocular pores ; leg 

 setae, coxa apparently 3, femur 1 on inner margin near base and 1 on outer mar- 

 gin near center, tarsus 1 eacb on inner and outer margins ; tibia one-third as 

 long as tarsus ; apparently 9 pairs of submarginal 8-shaped pores ; at least 8 

 pairs of submarginal setae, possibly more, tbe exact number not ascertainable 

 from tbe available material ; larger setae present at anterior end, but number 

 and position indeterminable. 



Apex of abdomen : Distorted, apparently with a shallow notch ; lobes barely 

 indicated ; setae, apical broken, interapical broken, inner ventral 5.4 ^ long, outer 

 ventral apparently 5 i* long ; anal ring with 6 setae apparently 4 fi long. 



Data, — Described from unmounted material, two mounted females, 

 and one mounted larva on an unknown host, Darling River, Bourke, 

 New South Wales, from W. W. Froggatt, received in 1910, Froggatt 

 No. 40, holotype and paratypes. 



This species is unusual in having the marginal quinquelocular pores 

 well removed from the 8-shaped pores, and in having large quinque- 

 locular pores replacing the multilocular pores on the abdomen. It 

 appears most closely related to midtiporum, stypheliae, and ungulatwn,. 



Asterolecanium largum, new species 



(Fig. 36, F-N) 



Habit. — Unknown. 



Test of female. — Nearly elongate elliptical, posterior end somewhat pointed ; 

 4 mm. long, 1.75-2 wide ; presumably nearly flat or very slightly convex dorsally, 

 flat ventrally ; yellow, transparent, fairly thin ; marginal and dorsal filaments 

 broken off ; larval exit possibly elliptical, in margin. 



Adult female. — In shape similar to test, 3.8 mm. long, 1.75-1.9 wide. 



Margin : 8-shaped pores in a single row terminating about one and a half 

 times the length of apical seta from setal bases, 16-20 a long and 8-10 wide, 

 usually around a pore's width apart; quinquelocular pores in a crowded single 

 or irregularly double row terminating at the third or fourth 8-shaped pore from 

 end of row, usually two and one-half times as numerous as 8-shaped pores ; 

 disk pores dorsad of, and much less numerous than, 8-shaped pores, terminating 

 near posterior quinquelocular pores. 



Dorsal surface : 8-shaped pores in 9 groups along median line, anterior group 

 with 28 and 38, respectively, in the 2 available specimens, next with 28 and 38, 

 next with 31, next with 24 and 39, next with 21 and 37, next with 8 and 32, next 

 with 19 and 31, next with 18 and 22, next with 16 and 20, or a total of 203 and 

 292, the 2 anterior groups somewhat longitudinal, the others rather transverse, 

 individual pores measuring 16-20 ji long and 8-14 wide, the majority 18-19 /j- 

 long and 12-13 wide ; minute 8-shaped pores not observed ; disk pores numerous ; 

 tubular ducts numerous except in groups of 8-shaped pores, 40 /j. long; dorsal 

 tubes present. 



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

 antenna and 1 or 2 very short ; 5 or 6 quinquelocular pores between antenna 

 and margin ; beak mutilated, presence or absence of setae indeterminable ; 

 spiracular bar nearly subcircular ; 40-60 quinquelocular pores extending from 

 spiracle to body margin in a row 2-5 pores wide ; multilocular pores, with 8-12 

 loculi, probably arranged in at least 3 or 4 complete, and certainly in 4 and 

 possibly in 5 interrupted rows, with a total of 162 pores observed, probably not 

 more than 200 in perfect specimens ; 5 or 6 dark-rimmed 8-shaped pores each 

 side of beak, some in inner submarginal and lateral areas arranged in 3 or 4 

 rather indefinite longitudinal rows, others in at least 2 transverse rows on 

 abdomen ; submarginal 8-shaped pores in an irregularly double row apparently 

 terminating near the seventh from the posterior pair of marginal 8-shaped pores, 

 at least as numerous as marginal 8-shaped pores ; submarginal setae in an 

 interrupted row, but number and terminating point indeterminable ; 6 setae 

 observed among multilocular pores, their arrangement indeterminable.
