THE SCALE INSECT GENUS ASTEROLECANIUM 179 



<> y. long and four IS fj. long, apparently with a tendency toward division on 

 dorsal side: ventral surface of apex sclerotized in a narrow transverse band 

 along margin and in a short linear band extending anteriorly from base of each 

 apical seta, area between sclerotized linear bands lightly sclerotized in dentate 

 rows. 



Larva. — Nearly elongate elliptical, posterior end slightly narrowed. 



Margin: With 28 8-shaped pores, the posterior and penultimate pairs slightly 

 larger than the next 4 pairs, which are the smallest of the row, the nexl 5 

 pairs gradually increasing in size anteriorly, and the anterior of these 5 the 

 largest of the row, the anterior 3 pairs about the same size as the pair behind 

 the largest, axes of the posterior 6 pairs slightly diagonal, axes of others 

 longitudinal : 3 pairs of setae at anterior end 



Dorsal surface: 8-shaped pores in a submedian row of 10 and a lateral row 

 of 2, on each half of body, the anterior 3 submedian pores slightly larger 

 than the others of that row. anterior pore of lateral row slightly larger than 

 posterior one and practically same size as anterior submedian pore, all pores 

 about three-fourths the size of marginal pores of same segments : disk pores 

 fairly close to marginal 8-shaped pores. 



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

 fairly stout. 1 slender; antenna! bases one-third length of antenna apart: beak 

 setae. 2 pairs apical. 1 pair median : anterior spiracle with 1 trilocular or 

 quinquelocular pore and 1 multilocular pore (having 8 loculi), posterior spiracle 

 with 1 trilocular pore; leg setae, coxa 4, femur 1 on inner margin near base 

 and 1 each on inner and outer margins near center, tarsus 2 on inner and 1 

 on outer margin: tibia three-eighths as long as tarsus; 9 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; 3 pairs of setae between 

 antennae and mouth parts. 



Apex of abdomen: Setae, apical 2." \i long, interapical apparently 3.6 fx. long, 

 outer ventral 3.6 m long; anal ring with 6 setae apparently 5 m long. 



Test of male — Elongate elliptical, 1 mm. long, 0.5 wide ; dorsal surface slightly 

 convex on anterior third, flat elsewhere, with a longitudinal median carina not 

 reaching anterior margin; flat ventrally : very pale yellow, transparent, thin, 

 slightly punctate ; marginal filaments whitish, apparently slightly shorter near 

 posterior end than elsewhere; dorsal filaments dark orange, in a dense group on 

 each side of median line on anterior third, apparently about as long as the anterior 

 marginal filaments. 



Male nymph. — Antenna apparently 9-segmented ; abdomen with a seta dorsally 

 on lateral margin of each of 5 segments and with a seta in ventral lateral area 

 of each of 2 segments : lobes indicated, each with 1 large and 2 small setae. 



Third-stage male. — Resembling adult female in shape, but smaller: margin 

 with 8-shaped pores terminating about twice, and quinquelocular pores about once, 

 an 8-shaped pore's length from bases of apical setae, the quinquelocular pores 

 about one and a half times as numerous as the 8-shaped pores ; dorsal surface 

 with 25-30 8-shaped pores in a curved group (ends of curve toward margin ) each 

 side of mouth parts, sometimes with a few in submarginal area posterior to those 

 groups: the pores comprising the group usually as large as anterior marginal 

 8-shaped pores, submarginal pcres about three-fourths as large as the largest 

 dorsal pores; ventral surface with atrium of spiracle slightly enlarged and con- 

 taining 1 quinquelocular pore, 1-5 similar pores in each spiracular pore band, 

 anterior and middle pairs of claws small, the posterior pair fairly large and 

 sharply pointed; apex of abdomen with setae arranged as in adult female, apical 

 setae broken, interapical and ventral same length as in adult female: anal ring 

 with 6 setae 20 ft long and with an inner row of probably (J and an outer one i>\ 

 an indeterminable number of pores, divided on dorsal side. 



Data. — Redescribed from specimens (six females, two larvae, one 

 male nymph, and three third-stage males, mounted) on bamboo. Yati- 

 yantota. Ceylon, from E. E. Green, letter of March 12. 1910. type. 



Attention is here called to three errors contained in the original 

 description of this species (i-. />. 31€) . There are three pairs of claws 

 rather than two, as stated, six setae on the anal ring instead of none. 

 and in the third-stage male, erroneously called second stage by Green, 

 there are three pairs of setae on the apex of the abdomen, rather than
