OF PSEUDOCOCCIDAE & ERIOCOCCIDAE 



*77 



Antennal bristles well defined ; segments VII and VIII each with a ventral bristle. Segment 

 IX with three bristles near its base and one apical hair-like seta. 



Thorax : 380-418 (403) ;x long. Prothorax : Pronotal ridges medially interrupted by a weak 

 sclerotization. Lateral pronotal sclerites and post-tergites small. Proepisternum without any 

 ridge-like sclerotization. Prosternum triangular, 24-34 (27)10. long ; prosternal ridge 92-98 

 (95) [x long. Prothoracic setae : Medial, lateral pronotal, posl-tergital and antespiracular dorsal 

 setae absent. One antespiracular ventral seta always present and one prosternal seta usually 

 present (av. 08) on each side. 



Mesothorax : Presculum 67-82 (76) jx long and 1 10-122 (i 16) jj. wide, the ratio being 1 : 15- 

 1-7 (i-6) ; laterally bounded by the prescutal ridges and posteriorly by the prescutal suture. 

 Scutum 43-52 (46) u. long, i.e. the ratio lengths of prescutum to scutum 1-6-1-9 ( r '7) : *■ 

 Prealare, prealar ridge, tegula, anterior and posterior notal wing processes well developed. 

 Scutellum 37-46 (40)1* long and 107-122 (t 16) jj. wide, i.e. the ratio 1 : 2-7-3-0 (2-9), and its 

 length to the length of the scutum 1 : 1-1-1-2 (1-15) ; scutellar ridge distinct. Postalare with 

 the anterior and posterior ridges joined. Postnotal apophysis strong. Mesopleuron : Meso- 

 pleural ridge continuous above the coxal articulation ; basalare slender. Subepisternal ridge 

 well developed. M esepisternum distinct and mesepimeron small. Lateropleurite comparatively 

 large, with an oval membranous area. Mesosternum : Basisternum 92-110 (ioi)u. long and 

 174-189 (180) (i wide ; antero-laterally and latero-posteriorly bounded by the marginal and 

 precoxal ridges respectively. Furca well developed. Mesolhoracic spiracle 15-18 (17)0. wide 

 at opening, with a 27-31 (29) (i. long supporting bar. Mesothoracic setae on each side : Prescutal 

 setae 6-9 (76) ; scutal setae 5-7 (6-i) ; scutellar setae 2-3 (28). Tegular setae 7-9 (79). 

 Anepisternum with 2-3 (2-8) mesepisternal setae. Postmesostigmatal setae in two groups, 3-4 

 (3-4) latero-ventrally and 2-3 (2-6) medially ; basisternal setae 10-15 (n-6). Metathorax : 

 Metapostnotal sclerites small ; metapostnotal ridge absent. Metapleural ridge attenuated as 

 usual towards the small pleural apophysis. Metepisternum and metepinurtni distinct. Precoxal 

 ridge weak and metasternal apophysis small Metathoracic spiracle identical with the meso- 

 thoracic. Metathoracic setae on each side : Metatergal setae 4-5 (4-2) ; metapleural setae 1-2 

 (i-6) ; postmetastigmatal setae 2-3 (2-6). Anterior metasternal setae 2-3 (2-4) and posterior 

 metasternal setae usually absent, although one seta was found in one specimen. 



Wings : 812-924 (868) \i long and 294-350 (322)0. wide ; alar setae almost always absent 

 and only one seta may occur (av. o-i). Hamulohalterae 58-67 (64)^ long and 15-18 (i6)(x wide ; 

 with one apically hooked, 52-67 (58)^ long seta, i.e. the ratio lengths of seta to hamulohaltera 

 1 : i-o-i-i (108).
