OF PSEUDOCOCCIDAE & ERIOCOCCIDAE 143 



Abdomen : 464-585 (502)0. long and 274-304 (289) y. wide. Tergites of segments I and II 

 small ; those of segments VIII and IX + X large and well sclerotized. Sternites of segment 

 VIII ill-denned. Ostioles well developed, 40-46 (43) n long at orifice. Abdominal setae on each 

 side : Dorsal setae : Fleshy setae 1-3 on segment I, usually 2-5 on segments II to VII (some- 

 times i on segment II and 6 on segments V and VII), and 1-3 on se ment VIII ; hair-like 

 setae 0-2 on segment I, 2-4 on segments II to VII, and 0-3 on segmeni VIII. Pleural setae : 

 Fleshy setae 0-4 on segments I to VIII ; hair-like setae 2-4 on segment 1, 3-5 on segments 

 II to VII, and 2-5 on segment VIII, including one slightly longer seta. Ventral setae : Fleshy 

 setae 1-2 on segment II, and usually 2-4 on segments III to VIII (sometimes 5 or 6 on segments 

 VI and VII, and only 1 on segment VIII) ; hair-like setae usually 2-4 on segments II to VII 

 (sometimes 3 or 5 on segment III), and 0-1 on segment VIII. Abdominal pores : Segments I 

 to VII with 6-10 (7-5), 0-2 (03), 0-2 (05), 0-2 (0-5), 0-1 (08), 1-3 (15), and 2-4 (28) pleural 

 pores. One dorsal pore may also occur on segments I and II, and one ventral pore on segments 

 II and III. 



Setae of glandular pouch consist of a pair of 397-488 (424)^ long tail setae and one seta about 

 40^1 long, i.e. the ratio length of the tail setae to the total length of the body 1 : 27-37 (3-2). 



Genital segment comparatively small ; subtriangular in dorsal view ; style slightly curving 

 upwards in lateral view. Penial sheath 140-153 (150)1* long and 82-795 (89)1* wide, i.e. the 

 ratio length to width 1-5-1 -9 (17) : 1, and the ratio its length to the total length of the body 

 1 : 87-10-3 (9-1). Basal ridge of penial sheath and its projection well developed ; process of 

 penial sheath absent. Aedeagus relatively wide at its basal rod, becoming narrower towards 

 its pointed apex. Setae of genital segment on each side : 3 setae always occur dorsally near 

 the base of the style ; 3-4 (3-8) smaller setae and 3-4 (32) setal sensilla present ventrally on 

 the penial sheath. 



Material : 8 specimens examined, collected by myself, 20. i v. 1964, on a bunch of 

 bananas bought in a London fruit shop, imported from the Canary Islands ; the 

 females were identified by K. Boratynski and confirmed by Dr. D. J. Williams. 



SACCHARICOCCUS Group 



SACCHARICOCCUS Ferris, 1950 



Saccharicoccus sacchari (Cockerell) 



(Text-figs. 27-30) 



Both macropterous and apterous forms of this species were available. 



(A) The macropterous form (Text-figs. 27 and 28). 



Living specimens light brown. A narrow and slender species, comparatively large, with 

 short antennae and short legs. When mounted, total length of body 1260-1400 (1316)^1, 

 width at mesothorax 252-280 (226) (i and wing expanse 1764-2072 (1932) ji. 



Body setae and pores : Antennae and legs with numerous fleshy, 2 1-27 \i long setae, and a 

 few hair-like, slightly longer ones. The body itself with fine hair-like setae only. Quadri- 

 locular and occasionally quinquelocular disc pores always present on head, thorax and abdomen, 

 about 6 [A in diameter. 



Head : Subtetrahedron ; subtriangular in dorsal view ; dorso-ventrally flattened in front 

 and lateral views ; ventral preocular depression entirely absent. Length from apex to post- 

 occipital ridge 122-137 ( I 3 I )i A '< from apex to neck 159-180 (171)^ ; width across the genae 

 180-198 (192) (i. Dorsal arm of midcranial ridge marked only by slender sclerotization, some-
