THE SCALE INSECT GENUS ASTEROLECANIUM 55 



Dorsal surface : 8-shaped pores in a submedian row of 3 and a Lateral row of 



5. on each half of body, the 3 lateral pores less than half the size of marginal 

 pores, others slightly larger than marginal: disk pores between lateral and 



marginal 8-shaped pores. 



Ventral surface: Antennal setae. T. 1: IV. 1: V. 0: VI. 2 long. -J stout. 2 fairly 

 stout. 2 slender: bases of antennae one-third length of antenna apart; beak with 

 2 pairs of apical setae ; anterior spiracle with 1 trilocular and 1 quadrilocular 

 or quinquelocular pore, posterior spiracle with 1 trilocular pore ; log setae, coxa 

 3, femur 1 on inner margin at base, tarsus 1 each on inner and outer margins : 

 tibia one-half as long as tarsus: apparently 9 pairs of submarginal 8-shaped 

 pores: 7 pairs of submarginal minute setae on abdomen, apparently 2 pairs of 

 submarginal larger setae at anterior end ; 3 pairs of setae near antennae. 



Apex of abdomen: Notch present: setae, apical 38 n long, interapical 2.5 y. 

 long, outer ventral 2 m long; anal opening in margin; anal tube very short and 

 slightly sclerotized throughout, but heavily sclerotized in a transverse band 

 near opening; anal ring with 6 setae, each apparently 1.8 /j. long. 



Data. — Described from one unmounted specimen, one mounted fe- 

 male, and three mounted larvae on Quereus bornemsis, Tawao, Elphin- 

 stone Province. British North Borneo. A. D. E. Elmer. October 1922 

 to March 1933. X. Y. B. G.. holotype and paratypes. 



This species seems rather closely related to sumatrae, from which it 

 can be easily segregated by the presence of a sclerotized projection on 

 each marginal 8-shapecl pore. 



ASTEROLECANIUM BRACHYLEXAE Brain 



(Fig. 10, A-E) 



Listed by Brain in 1920, in explanations of plates VII and VIII 

 (12) . as A. pustulous var. brachylenae. Although a section of the body 

 margin, the posterior apex of the body, and a photograph of tests were 

 shown in plates VII and VIII. brachylenae was not mentioned in the 

 text dealing with Asterolecanium {12. pp. 108-115). It differs from 

 pustulans so strongly that it is here given specific rank. 



Habit. — Living on bark, in pits. 



Test of female. — Slightly longer than wide or nearly circular. 1.5 mm. long. 

 1.25-1.5 wide: flat dorsally. strongly convex ventrally : brownish yellow, trans- 

 parent, fairly thin, smooth; marginal filaments whitish, dorsal filaments broken 

 off : elliptical larval exit in margin. 



Adult female. — Nearly circular, posterior end slightly produced: 1.25 mm. in 

 diameter. 



Margin: 8-shaped pores mostly in a double row but the posterior 7-14 pores 

 usually in a single row. terminating twice a pore's length from bases of apical 

 setae. 12-13 m long and 7-8 wide, the spaces between the pores ranging from 

 the width to the length of a pore, the two rows usually a pore's width apart : 

 quinquelocular pores in a crowded single or irregularly double row terminating 

 at, or 2 or 3 8-shaped pores from, the posterior pair of 8-shai>ed pores, one or 

 two times as numerous as 8-shaped pores of nearer row near ends of body, and 

 three or four times as numerous as 8-shaped pores near spiraeular pore bands: 

 disk pores dorsad of 8-shaped pores, terminating at the posterior or penultimate 

 pair of 8-shaped pores, one-third as numerous as 8-shaped pores of nearer row 

 at some points, quite as numerous at other points, also occurring ventrad of 

 quinquelocular pores, terminating at the posterior pair of 8-shaped pores and 

 as numerous as those dorsad of 8-shaped pores 



Dorsal surface: 8-shaped pores numerous, arranged in short transverse 

 along median line, and in circles paralleling the margin elsewhere, 12 13 - long 

 and 7-8 wide: minute 8-shaped and disk pores fairly numerous; tubular ducts 

 32 ij. long. 



Ventral surface: Antenna dome-shaped, with 2 setae slightly Longer and 3 

 shorter than diameter of antenna : 6-8 quinquelocular pores between antenna and 

 margin: beak with 2 pairs of setae: spiraeular bar subcircular; derm around 

 spiraeular opening with a fold containing 2 4 quinquelocular pore-, id 2d similar 

 pores extending to body margin in a row which is usually irregularly single
