OF THE FAMILY COCCIDAE 95 



sclerotized, irregular and exposed ; postnotal apophysis and postalare well developed, the latter 

 densely reticulated distally and without setae. Mesopostphragma with deep emargination. 

 Mesopleuron. Mesopleural ridge strong, not interrupted above coxal articulation ; pleural 

 apophysis and pleural wing process well developed. Hasalare vestigial, incorporated into pleural 

 wing process, not joining the latter with episternum. Subalare small. Epi sternum showing 

 irregular reticulation dorsally and polygonal reticulation ventrally ; subepisternal ridge well 

 developed, but below membranous cleft indistinct and only marked by a band of darker sclero- 

 tization. Epimeron small. Later opleurite not bounded anteriorly by an extension from 

 marginal ridge. Basisternum large, about 182 ji wide and 147 u. long, i.e. 1-20-1-35 (average 

 1 27) times longer than membranous area of scutum ; with strong median ridge and bounded 

 by strong marginal and precoxal ridges ; without setae. Eurca well developed. Mesothoracic 

 spiracle with well developed peritreme ; postmesospiracular setae numerous, consisting of 

 52-75 (average 61) f.s., arranged in a broad band behind the spiracles and prosternum, and with 

 a few on the episternae. Tegula small, membranous bulge with a small weak sclerite posteriorly 

 and with 2-6 (average 4-2) h.s. Third axillary wing sclerite with a small, pointed, ventral 

 projection at its base. Additional sclerite small, well sclerotized. Antemetaspiracular setae : 

 3-4 (average 3-6) f.s. 



Metathorax. Metanotum with posterior margin strong medially ; suspensorial sclerites 

 absent. Postnotum consisting of a small sclerite on each side. Metatergal setae : 1-5 (average 

 3-1) f.s., and usually one (0-2, average 1) h.s. on each side. Pleural ridge 1 onsiderably reduced, 

 extending only a short distance above coxal articulation. Vestigial precoxal ridge present. 

 Episternum reduced to a small subtriangular plate ; epimeron produced posteriorly. Meta- 

 thoracic spiracle similar to mesothoracic one. Dorsospiracultw setae : 10-18 (average 15) f.s. 

 and occasionally one h.s. Postmetaspiracular setae : 8-14 (average 12) f.s. and usually one 

 h.s. ; some f.s. occurring anterior to rest, close behind spiracles. Metasternal plate weak and 

 irregular, but more heavily sclerotized anteriorly. Anterior and posterior metasternal setae : 

 39-54 (average 45) and 12-26 (average 10) f.s. respectively. 



Wings hyaline; of medium length (980-1200, average 1097 (/), but comparatively broad 

 (width 430-520, average 481 a.), ratio width to length being 1 : 2-19-2-31 (average 2-27) ; 

 alar lobe and alar setae absent. Halteres absent. 



Legs long and slender, with fore pair shortest and hind pair longest ; ratio length of hind leg 

 to body length is 1 : 1-58-1-65 (average 162). Length of segments (in u.) :

Coxae with 10-15 (average 12) f.s. on the fore and 16-29 on the middle and hind coxa, and 

 each with 7-10 (average 78) h.s. ; fore coxa with 2-3 (average 23) capitate coxal bristles ; 

 apical seta about § as long as trochanter. Trochanters 19-23 u. wide ; with 6 oval sensilla, 

 9-15 f.s. and 5-7 h.s., the latter including 2 minute setae near basal ridge, one small seta on 

 outer margin and one long apical seta which, on the fore trochanter, is 1-2-1-4 (average 1-3) 

 times as long as width of trochanter. Eemora very slender, 27-34 V- wide, ratio width to length 

 of hind femur being 1 : 61-6-7 (average 6-4) ; with 27-46 f.s. and 8-14 h.s. Tibiae 17-21 (x 

 wide, ratio width to length of hind tibia being 1 : 18-0-20-8 (average 19-1) ; each with 89-114 

 setae of which 17-28 are h.s. and 89-114 f.s., the latter about twice as long as width of tibia ; 

 apical spur about the same size on all tibiae. Tarsi 17-21 (i. wide, hind tarsus 7-8-8-4 (average 

 8-2) times longer than wide ; with 24-42 f.s. and 13-23 h.s. ; tarsal digitules subequal, somewhat 

 longer than claw. Claws of medium length, a little longer than width of tarsus ; slightly curved, 

 with very small denticle near tip ; ungual digitules subequal, about as long as claw. 



Abdomen 400-490 (average 448) \j. long and 230-290 (average 263) \i wide.
