OF THE FAMILY COCCIDAF 



7i 



those of the ventral eyes 19-23 (average 21) y. in diameter and 2-8-3-3 (average 3-1) times as 

 much apart. Ocellus small. Ocular sclerite well sclerotized and polygonally reticulated 

 throughout. Preocular ridge with ventral part reaching midcranial ridge. Postocular ridge 

 weak dorsally, well developed lateroventrally and narrow but well defined posteromedially ; 

 below ocellus the ridge splits up, with the posterior part weak or lost entirely and the anterior 

 part strong, extending anterior to ocellus. Interocular ridge usually present, narrow, connecting 

 pre- and postocular ridges between lateral eyes (ridge sometimes absent on one side and 

 occasionally on both sides). Dorsal ocular setae absent ; ventral head setae : 3-5 (average 4) 

 h.s., situated on or just anterior to preocular ridge, a pair of these being considerably longer than 

 the others. Preoral ridge absent. Tendon-like apodeme long, arising from the anterior part of 

 an elongated ventral sclerite. Cranial apophysis very short, apex truncate with a large, 

 irregular central lobe. Mouth opening irregular. Anterior tentorial pits situated anterolateral 

 to mouth opening. 



Antennae 10-segmented, filiform ; 1 003-1 144 (average 1101) \i long, i.e. longer than half body- 

 length (ratio 1 : 1-62-1-74, average i-68), longer than posterior leg (ratio 1 : 1-16-1-19, average 

 1-17) and longer than penial sheath (1 : 3-06-3-40, average 318). Scape 61-72 (average 66) \l 

 long and 57-63 (average 60) [i wide, with 3-6 (average 4-1) h.s. Pedicel with distinct, poly- 

 gonal, dorsal reticulation ; 57-68 (average 64) [i long and 53-63 (average 59) u. wide ; with 

 7-14 (average 10) f.s., 8-15 (average 11) h.s. and a sensillum placodeum. Segment III bulging 

 in middle, 1-7-2-1 (average 1-9) times longer than wide (76-95, average 84 jx long and 38-46, 

 average 43 ji. wide) ; with 6-8 (average 7) h.s. and 21-31 (average 24) f.s., the latter, as on the 

 other antennal segments, very short, about 0-4-0-6 (average 05) times as long as width of 

 segment III ; with 1—3 usual sensilla basiconica. Segments IV-IX cylindrical ; lengths of
