pores in a single row terminating caudad of the posterior row of multilobular 

 pores, nearly as numerous as corresponding marginal 8-shaped pores ; submarginal 

 setae in a complete row terminating caudad of posterior row of multilocular pores : 

 4 or 5 setae in the posterior row of multilocular pores and 2 in each of other 

 complete rows. 



Apex of abdomen: Setae, apical (on ventral surface) 4 ix long, interapical 

 4 ,u long, outer ventral 4 u long ; a cluster of 4 or 5 pores, surrounded by a some- 

 what rectangular sclerotized band, situated between the interapical setae, each 

 of these pores about the same size as the smallest multilocular pores (near genital 

 opening i and apparently with 6 loculi ; a circular opening in ventral surface 

 directly anterior to this group of pores, margin of opening sclerotized. 



Larva. — Nearly elliptical. 



Margin : With 28 8-shaped pores, axes of all longitudinal : a pair of minute 

 setae close to each of the posterior 3 pairs ; 3 pairs of setae anteriorly. 



Dorsal surface: 8-shaped pores in a lateral row of 9 on each half of body, 

 the posterior pores smaller than the anterior ones, the largest about three- 

 fourths the size of a marginal pore; disk pores between lateral and marginal 

 8-shaped pores. 



Ventral surface : Antennal setae, I, 1 ; IV, 1 : V, 1 : VI, 2 long, 2 stout, 3 fairly 

 stout, 1 slender ; distance between antennal bases equal to one-third length of 

 antenna : beak setae, 1 pair apical, 1 pair median, 1 pair basal ; spiracle with 

 2 quinquelocular pores ; leg setae, coxa 3. femur 0, tarsus 1 each on inner and 

 outer margins; tibia one-half as long as tarsus; claw very short; 9 pairs of 

 submarginal 8-shaped pores: apparently pairs of submarginal minute setae, 

 on abdomen and thorax. 1 pair of submarginal larger setae at anterior end ; 

 4 pairs of setae near antennae. 



Apex of abdomen : Lobes indicated ; setae, apical 27 fi long, interapical 4 n 

 long, dorsal 1 n long, outer ventral 1.8 n long ; anal opening apical ; anal tube 

 very short, bulbous, sclerotized ; anal ring a sclerotized band, apparently without 

 setae. 



Data. — Described from 2 unmounted .specimens, 1 intact and 1 

 fragmentary mounted female, and 15 mounted larvae from Livistona 

 merriUL Paracale. Camarines. Luzon. Philippine Islands, Ramos and 

 Edano. November-December 1918. U. 8. X. H.. holotype and paratvpes. 



Asterolecanium shiguJare is unusual in having pores at the apex 

 of the abdomen enclosed in a somewhat rectangular sclerotized area. 

 This pore plate may correspond to the anal ring found in many 

 species. 



Asterolecanium sxaxianae, new species 



(Fig. 65, B-F ; pi. 9, ^Y) 



Habit. — Living on the lower surface of leaves. 



Test of female. — Longer than wide to nearly circular, often irregular in 

 outline owing to growth against hairs on leaf, posterior end slightly produced; 

 1 mm. long and 0.6 wide, or 0.7-1 mm. in diameter : convex dorsally, posterior end 

 flattened, with transverse striatums ; flat ventrally; pale greenish yellow. 

 translucent, smooth, shiny or rather dull: marginal filaments whitish, fragmen- 

 tary; elliptical larval exit in dorsal surface at margin. 



Adult female. — In shape similar to test. 0.6-0.9 mm. long. 0.3 wide. 



Margin: 8-shaped pores_ in a single row terminating about three-fourths 

 length of an apical seta from bases of setae, each pore with a sclerotized tongue- 

 shaped projection on dorsal edge, posterior pores 8 fi long and 5 wide, the others 

 9 fx long and 5 wide, usually from the width to the length of a pore a par I : 

 quinquelocular pores in a single row continuing around apex of abdomen between 

 apical setae, slightly more numerous than corresponding 8-shaped port's. 



Dorsal surface: Minute 8-shaped pores numerous; disk pores fairly numerous; 

 tubular duets 24 /x long. 



Ventral surface: Antenna conical, with 1 seta slightly longer than diameter of 

 antenna: beak with 2 pairs of setae; spiracular bar fairly broad: 1." 20 quinque- 

 locular pores extending from spiracle to body margin in a single row ; multilocular 

 pores, totaling 20 24 and having 7-10 loculi, in 3 complete rows of 5 8 I usually 8) 

 each: a group of 3-6 dark-rimmed 8-shaped pores each side of beak and a few
