THE SCALE INSECT GEXUS ASTEROLECANLUM 93 



ASTEROLECANIUM FLAGELLARIAE, new species 

 (Fig. 25. A-H ; pi. 7. X) 



Habit. — Living on both surfaces of leaves. 



Test of female. — Elongate ovoid. 0.7-0.9 mm. long, 0.5-0.75 wide: nearly flat 

 to slightly oval dorsally. sometimes with faint transverse striations, flat ven- 

 trally; pale greenish yellow, transparent, shiny: marginal filaments deep sal- 

 mon : elliptical larval exit in dorsal surface at margin. 



Adult female. — Elongate ovoid, posterior end sometimes slightly produced; 

 0.65-0.85 mm. long. 0.5-0.7 wide. 



Margin: 8-shaped pores in a single row. interrupted near posterior end for a 

 space <>f 1D-20 pores (1 of specimens examined, without interruption), contin- 

 ued for 2-12 pores beyond interruption and terminating one to three times a 

 pore's length from bases of apical setae. 7 or 8 ,u long and 3 wide, about the 

 width of a pore apart ; trilocular pores in a single row between spiracular pore 

 bands, and 15-25 pores outside those bands, one and a half times as numerous 

 as 8-shaped pores. 



Dorsal surface: Minute 8-shaped pores in lateral areas, sparse; disk pores 

 sparse: tubular ducts 20 fi long. 



Ventral surface : Antenna slightly raised, more or less crenulate. with 2 

 setae as long as diameter of antenna ; spiracle with bar very slender, atrium 

 enlarged, bag-shaped, and containing 5-S quinquelocular pores, opening broad, 

 extending into a furrow which flattens out near margin, 8-15 trilocular pores 

 extending to body margin in an irregularly single or double row; multilocular 

 pores, totaling 20-26 and with 6-11 (usually 10 or 11) loculi, in 3 complete and 

 1 or 2 interrupted rows, posterior row with 8-10, penultimate with 8-12, next 

 with 5-7, each of interrupted rows with 2 : a group of 2-5 dark-rimmed 8-shaped 

 pores each side of mouth parts, a few anterior and a few posterior to beak, 

 mostly in lateral area, and a few in median area near or among multilocular 

 pores : submarginal 8-shaped pores in a single row terminating near the posterior 

 pair of marginal 8-shaped pores, about half as numerous as marginal 8-shaped 

 pores; 3 pairs of submarginal setae on abdomen, the posterior pair fairly near 

 the posterior pair of marginal 8-shaped pores ; 2 pairs of setae in the posterior 

 row, 1 pair in each of the other complete rows, and 1 pair in each of the 

 interrupted rows of multilocular pores. 



Apex of abdomen : Lobes barely indicated : setae, apical at least 36 ^ long 

 (tips broken), probably not more than 40, interapical (directly anterior to 

 apical) 1-2 fu, long, outer ventral 1-2 ,u long: anal opening dorsal, close to body 

 margin, circular, its margin membranous: anal tube membranous, cylindrical: 

 anal ring a sclerotized band. 



Larva. — Elliptical. 



Margin : With 2S 8-shaped pores, their axes transverse, anterior pair the 

 largest : a pair of minute setae close to each of the posterior 3 pairs of pores ; 

 3 pairs of setae at anterior end. 



Dorsal surface: 8-shaped pores, totaling 2^ or 30. arranged in a snbmedian 

 row <>f 8 or 9 and a lateral row of 6 or 7 on each half of body, and apparently 

 about two-thirds the size of a posterior marginal pore: disk pores sparse, between 

 submedian and lateral and lateral and marginal 8-shaped pores. 



Ventral surface: Antenna! setae. I. 1 : IV. 1: V. 1: VI. apparently 2 long. 2 

 stout, 3 fairly stout. 1 slender: bases of antennae one-third length of antenna 

 apart; beak apparently with 1 pair of setae at tip and 1 pair near base: spiracle 

 with 1 trilocular and 1 quincpielocular pore: leg setae, coxa 3. femur 1 on inner 

 margin near base and 1 on outer margin near ••enter, tarsus 2 on inner and 1 

 on outer margin: tibia one-third as long as tarsus; pairs of submarginal 

 8-shaped pores ; submarginal setae apparently in 11 pairs, occurring on abdomen, 

 thorax, and head: 3 pairs of setae between antennae and mouth parts. 



Apex of abdomen : Lobes barely indicated; setae, apical 50 u long, interapical 

 3.6 /u long, outer ventral minute, broken; anal opening in margin, circular: anal 

 tube sclerotized near opening, membranous at inner end, fairly small at opening, 

 then enlarged but constricted in center, large at inner end: anal ring sclerotized. 



Test of male. — Elliptical, 0.7.V1 mm. long. 0.45 wide : flat dorsally and ventrally ; 

 pale greenish yellow, transparent, thin: marginal filaments rubbed off. 



Adult ))ia1e.—0.95 mm long.
