Abdomen : Four segments each with a pair of setae dorsally on lateral margin, 

 2 segments each with a pair of setae in ventral lateral area ; each lobe area 

 with 1 long and 2 short setae ; penis sheath with 2 pairs of setae dorsally near 

 base, and 5 or 6 setae on each side of ventral opening. 



Male nymph. — Distinguishing characters similar to those of adult male. 



Third-stage male. — Resembling second stage in shape ; margin with 8-shaped 

 pores more numerous and more regularly spaced than in second stage, usually 

 once or twice (sometimes as much as six times) a pore's length apart; ventral 

 surface with 3 pairs of legs represented by circular sclerotized areas apparently 

 without claws, but with minute clear areas suggesting setal bases, 2 pairs of 

 setae in median abdominal area ; apex of abdomen as in second stage. 



Data. — Redescribed from unmounted material and the following 

 mounted specimens : Eight females and 6 larvae on Arundinaria sp., 

 Pundaluoya, Ceylon, E. E. Green, received March 12, 1910, and Septem- 

 ber 11, 1911, type material; 2 females, Ceylon, Maskell Collection No. 

 354; 1 female, Ceylon, E. E. Green, Cockerell Collection; 7 females, 

 1 second-stage specimen, 3 larvae, 3 adult males, 3 male nymphs, and 

 1 third-stage male on Arundinaria sp., Pundaluoya, Ceylon ; 3 females 

 and 6 larvae on Bambusa arwndinacea, Ambagamuwa, Ceylon, July 

 1885, U. S. N. H. ; 5 females, 10 larvae, 3 adult males, and 3 male nymphs 

 on Arundinaria sp., Eton, Ceylon, March 18, 1895; 1 female on Bam- 

 busa spinosa, Hue, Annam. Indo-China, A. S. Hitchcock, September 

 26, 1921, U. S. N. H. 



Although the marginal 8-shaped pores are reduced in number, those 

 present are well defined. Green (42, p. 336) expressed uncertainty as 

 to whether there was a complete marginal series. In stained speci- 

 mens at hand the marginal row of 28 8-shaped pores is apparent in 

 larvae inside adults, as well as in those removed from the leaves. Green 

 did not mention these pores in the early larvae, although he did note 

 their presence in the later larvae (42, p. 337) . 



Asterolecanium longum is closely related to miliaris and caudatum, 

 but can be separated from these by its small number of marginal 

 8-shaped pores. 



Asterolecanium luteolum, new species 



(Fig. 39, A-K; pi. 7, B) 



Habit. — Living on the lower surface of leaves in slight depressions, in crevices 

 of rough bark, or in pits in smooth bark. 



Test of female. — Ovoid, 0.65-0.85 mm. long, 0.5 wide ; convex dorsally, sloping 

 to posterior end, flat at tip, with a faint longitudinal median carina and lateral 

 carinae meeting near anterior end and with distinct transverse striations ; 

 slightly convex ventrally ; deep yellow, transparent, thin, shiny ; marginal 

 filaments whitish, shorter near posterior end than elsewhere ; dorsal filaments 

 also whitish, shorter than marginal, located in lateral and submarginal area; 

 semicircular larval exit in margin. 



Adult female. — Ovoid to nearly circular, posterior end slightly produced ; 

 0.6-0.8 mm. long, 0.5 wide. 



Margin : 8-shaped pores in a single row terminating twice a pore's length 

 from bases of apical setae, the posterior pores 6 n long and 4 wide, the others 

 8 fi long and 5 wide, usually about a pore's width apart ; quinquelocular pores 

 in a single row terminating within 8 pores from end of row of 8-shaped pores, 

 as numerous as 8-shaped pores near posterior end, at least one and one-half 

 times as numerous as those pores anterior to posterior spiracular pore bands. 



Dorsal surface: 8-shaped pores scattered in lateral and submarginal area 

 except at posterior end, fairly numerous, the majority 4 /* long and 3 wide, but 

 some 5 jj, long and 4 wide; minute 8-shaped pores numerous in median area, 

 sparse in submarginal area ; disk pores sparse ; tubular ducts 24 p long. 



Ventral surface : Antenna conical, with 2 setae longer than diameter of 

 antenna ; beak with 2 pairs of setae ; spiracular bar slightly expanded at inner
