OF PSEUDOCOCCIDAE & ERIOCOCCIDAE 171 



Genital segment : Genital capsule 137-156 (143)^ long and 73-79 (76)1/ wide, i.e. the ratio 

 its length to its width 1-8-2-0 (1-9) : 1, and its length to total body length 1 : 7-9-8-9 (8-5) ; 

 style undulating in lateral view. Anal opening 18-21 (20) [x in diameter. Ventrally, a median, 

 longitudinal slender ridge present, giving off two lateral branches extending towards the base 

 of the aedeagus. Aedeagus strongly developed and ventrally sclerotized ; also with latero- 

 ventral heavy sclerotizations and a pair of small processes on each side. Setae of genital 

 segment : Dorsally two setae, about 61 jx long always present on each side near the base of the 

 style ; ventrally 5-6 (5-2) setae occur on each side of the genital capsule. 



Material : 10 specimens examined, collected by myself on Araucaria excelsa, 

 in Alexandria, Egypt, U.A.R., during the last week of June and the first week of 

 July, 1961. 



Eriococcus orariensis Hoy 



(Text-figs. 41, 42) 



Winged forms only known ; living specimens not available. The males moderately robust, 

 comparatively small, with short antennae and short legs. Mounted specimens 812-938 (882) ;x 

 long, 224-266 (25o)(x wide at mesothorax and 1652-1848 (1736)^ wing expanse. 



Body setae : Antennae and legs with fleshy and hair-like setae, about 12 and i8(x long 

 respectively ; the body itself with slightly smaller hair-like setae only. 



Head : Subtetrahedron ; subtriangular in dorsal view and rather rounded in front view ; 

 ventral preocular depression hardly indicated in lateral view. Length from apex to post- 

 occipital ridge 70-85 (76)^ ; from apex to neck 1 16-125 i 122 )^ '• width across the genae 156- 

 1 ^>5 ( I 59)M- Dorsal arm of midcranial ridge short, joined to the lateral and the ventral arms 

 at the apex of the head. Postoccipital ridge strongly developed, with the lateral extremities 

 bending posteriorly and giving off a short heavy sclerotization anteriorly. Dorsomedial part 

 of epicranium narrow. Preocular and postocular ridges widely separated ; the latter ventrally 

 articulates with a small additional ridge. Preoral ridge slender. Eyes : Dorsal simple eyes 

 slightly projecting beyond the lateral margins of the head ; their corneae 15-18 (16) ;x in 

 diameter and separated by 85-96 (89) u., i.e. 4-7-6-0 (5-4) times their diameter apart. Ventral 

 simple eyes subequal in diameter and 18-24 t 21 )^ apart. Lateral ocelli anteriorly attached to 

 postocular ridges. Ocular sclerites large. Cranial apophysis apically bifurcate. Tentorial 

 bridge stout. Dorsal head setae 8-10 (9-8) on each side ; each gena with 2-3 (2-7) genal setae. 

 Ventral head setae on each side : 3-5 (4-1) in the area of the ventral preocular depression, 

 forming on both sides a transverse band ; anteriorly a row of 2-3 (2-7) h.s. present on each 

 side of the ventral arm of the midcranial ridge. 



Antennae : Rather moniliform ; normally 10-segmented ; 329-354 (339) [x long, i.e. shorter 

 than half the total length of the body, the ratio being 1 : 2-4-2-8), and about as long as the 

 hind legs, the ratio 1 : 1-1-1-2 (1-15). Scape 31-34 (32) jx long and 34^ wide at base ; always 

 with 4 h.s. Pedicel 43-46 (45)fx long and 27-31 (28) jx wide ; with 4-10 (6-6 f.s., 8-13 (11-3) 

 h.s. and a sensillum placodeum. Flagellum : Flagellar segments 18-2 ijx wide, with the pre- 

 terminal segments becoming slightly wider. Segment III club-shaped and longest of all, the 

 ratio its length to the length of the terminal segment 1-40-1-54 (1-5) : 1, and the ratio its width 

 to its length 1 : 2-9-3-3 (3 -2 )- Segments IV to IX barrel-shaped, the ratio width to length of 

 segment IX being 1 : 1-0-1-4 ( I-2 ) > terminal segment pear-shaped. Segments VIII, IX, X 

 and sometimes VII carry a number of apically knobbed capitate sensory setae. In the following 

 table the lengths of the flagellar segments and the number of setae on each are given :
