THE SCALE INSECT GENUS ASTEROLECANIDM 143 



Closely resembling longuhim, but with a single, instead of a double, 

 row of submarginal 8-shaped pores and with two short, as well as 

 two long, setae on the antenna. The larva is distinguished from that 

 of loncjulnm by having 28, instead of 26, marginal 8-shaped pores, 

 and only 1 pore near each spiracle. 



ASTEROLECANIUM ORAXIAE, 11CW species 

 (Elg. 40, A-F; pi. 9, J) 



Habit. — Living on the lower surface of leaves. 



Test of female. — Elongate ovoid, around 1.4 mm. lo-ng, 0.65 wide; truncate 

 at anterior end, nearly uniform in width on anterior third, tapering gradually 

 to posterior end; dorsally convex at anterior end, sloping gradually to posterior 

 end: flat ventraily; brownish yellow, transparent, rather thick; marginal fila- 

 ments apparently whitish, fragmentary; larval exit not observed. 



Adult female. — Elongate, around 1.25 mm. long. 0.5 wide. 



Margin : 8-shaped pores in a single row terminating twice or three times 

 length of an apical seta from bases of setae, the posterior pores 7 n long and 



4 wide, the others 8 or 9 ft long and 5 wide, a pore's length apart at anterior 

 end. two to six times that distance apart near posterior end; trilocular pores 

 (with some quinquelocular pores intermixed) in a single row from slightly 

 anterior to anterior spiracular pore bands to halfway between posterior spiracular 

 pore bands and the posterior pair of 8-shaped pores, less numerous than 8-shaped 

 pores at ends of rows, one and a half times as numerous elsewhere. 



Dorsal surface; Two and 6 8-shaped pores observed in different specimens 

 of the meager available material, these fairly close to anterior margin and 12 ;x 

 long and 8 wide; minute 8-shaped pores numerous on anterior third of specimen, 

 sparse elsewhere : disk pores sparse; tubular ducts 24 \i long. 



Ventral surface: Antenna circular, slightly raised, with 2 setae slightly 

 longer than diameter of antenna ; beak with 2 pairs of setae ; spiracle with bar 

 expanded at inner end and with atrium enlarged, bag-shaped, and containing 



5 or 6 quinqnelocular pore-. 4-0 similar pores extending from spiracle to body 

 margin in a single row: multilocular pores, with or 10 loculi, in 2 complete 

 rows of 11-16 each. 1 interrupted row of 8 or Id, and 5 interrupted rows each 

 with 2-4. or a total of 47-49; 2 or 3 dark-rimmed 8-shaped pores each side of 

 beak, a few scattered on anterior end. and a few on posterior half of body 

 tending toward arrangement in transverse rows mostly in lateral areas (some 

 in median area close to month parts) ; submarginal 8-shaped pores apparently 

 in a single row, terminating near the penultimate row of multilocular pores; 

 submarginal setae in a complete row terminating halfway between the posterior 

 pair of marginal 8-shaped pores and bases of apical setae; 2 pairs of setae in 

 the posterior row of multilocular pores and 1 pair in each of the next 3 rows. 



Apex of abdomen: Setae, apical 20 y. long, interapical 1-2 n long, outer 

 ventral 4 /jl long; anal opening not cleary differentiated, apparently in margin; 

 anal tube very short or absent; anal ring not clearly differentiated, apparently 

 a somewhat elliptical plate which is sclerotized on ventral side and has 2 

 setae 16 /x long apparently arising from very short, inconspicuous collars, and 

 a clear area suggestive of a pore between base of seta and rim of collar. 



Larva. — Elliptical. 



Margin: With 28 8-shaped pores varying slightly in size, the anterior pair as 

 large as any of the others, axes of all practically longitudinal; a minute seta 

 close to each pore of the posterior 3 pairs: .", pairs of setae at anterior end. 



Dorsal surface: 8-shaped pores, totaling 40-42. in a submedian row of 9-11 

 and a lateral row of 10-12, on each half of body, varying slightly in size, 

 anterior pores of each row usually larger than the others, and nearly as large 

 as marginal pores of same segments ; disk pores near some of the lateral 8-shaped 

 pores. 



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

 fairly smut: antennal bases about one-half length of antenna apart : beak setae, 

 2 pairs apical, 1 pair median; spiracle with 1 trilocular and 1 quinquelocular 

 pore or with 2 quinquelocular pores; leg setae, coxa 3. femur 0. tarsus appar- 

 ently 1 each on inner and outer margins; tibia one-third as long as tarsus; 9 

 pairs of submarginal 8-shaped pores; apparently 7 pairs of submarginal minute 

 setae, on abdomen and thorax. 1 pair of slightly larger submarginal setae at 

 anterior end; 3 pairs of setae near antennae and mouth parts.
