same size as marginal pores of same segments, lateral pores about half the size 

 of marginal pores of same segments; disk pores occurring fairly close to margi- 

 nal 8-shaped pores, and between submedian and lateral 8-shaped pores. 



Ventral surface : Antennal setae, I, apparently 1 ; IV, 1, V, ; VI, 2 long, 

 2 stout, 2 fairly stout ; antennal bases about one-half length of antenna apart ; 

 beak with 2 pairs of setae at tip; spiracle with 2 quinquelocular pores; leg 

 setae, coxa 3, femur 0. tarsus 1 on inner margin ; tibia one-half as long as tarsus ; 

 10 pairs of submarginal 8-shaped pores; 8 pairs of submarginal minute setae, 

 on abdomen and thorax. 2 pairs of submarginal larger setae at anterior end ; 1 

 or 2 setae between antennae. 



Apex of abdomen : Setae, apical 45 \i long, interapical 5.4 n long, outer ventral 

 apparently 5 \i long ; anal ring with 6 setae 2 fi long. 



Data. — Described from one test (partially destroyed in mounting 

 insect), one mounted female, and two mounted larvae from Quercus 

 hystrix, 'Toetoepan,'' Tapanuli. Sumatra, H. S. Yates. N. Y. B. G.. 

 holotype and paratypes. 



Asterolecanium thespesiae Green 



(Fig. 71, B-F; pi. 6. X) 



Described in 1909 (±2, p. 3S1). 



Habit. — "On small branches of Thespesia populnea. Jaffna. March. The 

 insects occupy small depressions in the bark." (' f 2. p. 331.) 



Test of female. — Broadly ovoid, posterior end very slightly produced; L85-2 

 mm. long, 1.25-1.75 wide; nearly flat dorsally. lateral margins sometimes slightly 

 raised, thereby giving the effect of marginal carinae, usually with a low, rather 

 indistinct longitudinal median carina and faint transverse striations ; usually 

 distinctly convex ventrally, sometimes nearly flat : brownish yellow, transparent, 

 fairly thick; marginal filaments whitish, fragmentary; dorsal filaments whitish, 

 very short ; elliptical larval exit in margin. 



Adult female. — Nearly circular, posterior end slightly produced; 1.25-1.75 mm. 

 in diameter. 



Margin : 8-shaped pores in a double row (the row sometimes triple for a few 

 pores) terminating twice a pore's length from bases of apical setae. 10-12 n long 

 and 8 wide, the intervals between them varying from the width to twice the 

 length of a pore, the 2 rows about a pore's width apart : quinquelocular pores in 

 a single row, often crowded with the row appearing double in lateral area, 

 terminating with the 8-shaped pores or beyond, at least as numerous as cor- 

 responding 8-shaped pores of nearer row at ends of body, two or three times as 

 numerous as 8-shaped pores in crowded lateral areas; disk pores in a rather in- 

 definite row dorsad of 8-shaped pores, irregularly spaced and rather sparse, also 

 in a single row ventrad of quinquelocular pores, not quite so numerous as 

 8-shaped pores of nearer row. and terminating near end of that row. 



Dorsal surface : 8-shaped pores numerous, present except near posterior end 

 and close to margin, median pores tending toward arrangement in longitudinal 

 rows, the others toward arrangement in transverse rows. 9-12 m long and 6-8 

 wide, the median pores as large as any of the rest: minute 8-shaped pores nu- 

 merous; disk pores fairly numerous: tubular ducts 30-32 fx long. 



Ventral surface: Antenna bluntly conical, with 2 setae slightly longer, and 3 

 a little shorter, than diameter of antenna: 3 or 4 quinquelocular pores between 

 antenna and margin; beak with 2 pairs of setae: spiracle with bar subcircular. 

 atrium enlarged, shallow, and containing 6 quinquelocular pores, 6 (at anterior 

 spiracle) to 15 (at posterior spiracle) similar pores extending from spiracle to 

 body margin in a single row; nmltilocular pores, totaling 177-190 and with 7 It) 

 toculi, apparently in 7 or 8 complete rows, the anterior row apparently anterior 

 to posterior spiracles, posterior row with 15-17 pores, penultimate row with 

 20-27. next with 31-37. next with 30-36. next with 26-31, next with 19. next with 

 14. and anterior row with 15; 1-4 dark-rimmed 8-shaped pores each side of beak. 

 a few scattered anterior to mouth parts, and a few tending toward arrangement 

 in 5 or t; transverse rows posterior to mouth parts: submarginal 8-shaped pons 

 in a double row terminating near posterior row of nmltilocular pores, 2 opposite 

 each or every other marginal 8-<haped pore : submarginal setae in a complete
