OF PSEUDOCOCCIDAE & ERIOCOCCIDAE 175 



Genital segment : Genital capsule elongate, 119-134 (128)51 long and 43-49 (46) ;x wide, the 

 ratio being 2-6-3-0 (2-8) : 1, and the ratio its length to the total length of body 1 : 6-2-7-8 (6-9). 

 Style rather straight in lateral view, with a pointed apex. Anal opening about i2y. in diameter. 

 Aedeagus with a well sclerotized ventral margin and a sharply pointed tip. Setae of genital 

 segment : Dorsally 2 comparatively long setae always present on each side of the style at about 

 half its length. Ventrally 4-5 (4-6) similar setae occur on each side of the genital capsule. 



Material : 10 specimens from two lots examined, all of which entirely agreed 

 with each other. The specimens of one lot were collected by J. M. Kelsey, on 

 Leptospermum scoparium, in Ashburton, New Zealand, 10. vi. 1948 ; the other 

 specimens were collected by J. M. Hoy, on the same host plant, in Palmerston 

 North, New Zealand, 21.iii.1956. 



Eriococcus buxi (Fonscolombe) 

 (Text-figs. 43, 44) 



Macropterous males only known ; living specimens not available. The males moderately 

 robust, comparatively small, with short antennae and moderately long legs. When mounted, 

 942-1050 (980) [i long, 266-294 (280) u. wide at mesothorax and 1862-2100 (2002) u. wing 

 expanse. 



Body setae : Antennae and legs with about i8(ji long fleshy setae and somewhat longer hair- 

 like ones ; both types of setae hard to separate. Body itself with hair-like setae only. 



Head : Subtetrahedron ; subtriangular in dorsal and front views ; ventral preocular 

 depression hardly indicated in lateral view. Length from apex to postoccipital ridge 67-76 

 (70)51 ; from apex to neck 140-150 (144)1,1 ; width across the genae 174-183 (180)51. Dorsal 

 arm of midcranial ridge short, joining lateral and ventral arms at the apex of the head. Post- 

 occipital ridge well developed, laterally giving off two branches, one anteriorly and the other 

 posteriorly. Dorsomedial part of epicranium slightly raised. Preocular and postocular ridges 

 well separated ; ventral part of the former atrophied. Preoral ridge slender. Eyes : Dorsal 

 simple eyes not projecting beyond the outer margins of the head ; their corneae 18-24 ( 2I )( Jl 

 in diameter and separated by 58-61 (59)51, i.e. 2-4-3-3 ( 2 "7) times their diameter apart. Ventral 

 simple eyes 21-24 ( 22 )i JL an ^ 18-21 (20)51 apart. Lateral ocelli closely attached to postocular 

 ridges. Ocular sclerites large. Cranial apophysis apically truncate. Tentorial bridge stout. 

 Dorsal head setae 11-15 (12-8) on each side ; each gena with 9-15 (n-8) genal setae ; setae of 

 ocular sclerites 10-13 ( II- 6)- Ventral head setae on each side : 2-3 (2-6) between the ventral 

 eyes ; 11-15 (13-2) in the area of the ventral preocular depression, forming on both sides a 

 transverse band ; 4-5 (4-2) on each side of the ventral arm of the midcranial ridge. 



Antennae : Rather filiform ; 9-segmented ; 458-506 (476)51 long, i.e. about as long as half 

 the total body length, the ratio being 1 : 2-0-2-1 (2-05), and slightly shorter than the hind legs, 

 the ratio 1 : 1-1-1-3 ( I-2 )- Scape 37-40 (39)51 long and 34-37 (36)51 wide at base ; always 

 with 4 h.s. Pedicel 43-49 (46) ji long and 31-37 (34) 51 wide ; with 2-5 (3-5) f.s., 10-16 (13-3) 

 h.s. and a sensillum placodeum. Flagellum : Flagellar segments 21-2451, wide, with segment 

 III somewhat wider and segment IX somewhat narrower. Segment III club-shaped and 

 longest of all, the ratio its length to the length of terminal segment 2-6-2-9 (2-8) : 1, and the 

 ratio its width to its length 1 : 3-2-3-6 (3-5). Segments IV to VIII rather barrel-shaped, the 

 ratio width to length of segment VIII being 1 : 1-5-1-9 (i-6) ; terminal segment pear-shaped, 

 shortest of all and always with 5-6 apically knobbed capitate sensory setae. The following table 

 shows the lengths of the flagellar segments and the number of setae on each :
