THE SCALE INSECT GENUS ASTEROLECANIUM 149 



Larva. — Nearly elliptical, posterior end slightly narrowed. 



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

 larger than the others, axes of the posterior 2 or 3 pairs transverse, of the next 

 2 or 3 pairs somewhat diagonal, and of the others longitudinal ; 3 pairs of setae 

 at anterior end. 



Dorsal surface: 8-shaped pores in a suhmedian row of 4 or 5 on each half 

 of body, the anterior pore and the second from it one-third or one-fourth larger 

 than the others, the largest pores slightly larger than marginal pores of same 

 segments, the others smaller; disk pores in lateral area. 



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

 stout, 1 slender ; antennal bases one-third length of antenna apart ; beak setae, 

 2 pairs apical, 1 pair median; 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 one-half as long as tarsus; 

 9 pairs of submarginal 8-shaped pores ; 6 pairs of submarginal minute setae on 

 abdomen, 3 pairs of submarginal larger setae at anterior end; 1 pair of setae 

 between antennae and mouth parts. 



Apex of abdomen : Notch present ; setae, apical 27 m long, interapical 5.4 n long, 

 inner and outer ventral each 3.6 /jl long ; anal ring with 6 setae 3.6 n long. 



Data. — Described from one parasitized test, two mounted females, 

 and two mounted larvae on Bambusa sp., Kachek, Hainan Island, 

 China, A. S. Hitchcock, October 13, 1921, U. S. N. H., holotype 

 and paratypes. 



Closely resembling mhnitum and 7iiinusculum, but differing from 

 them in having the marginal row of 8-shaped and quinquelocular 

 pores terminating the length of an apical seta from bases of setae, 

 instead of three to six times that distance, and in the tubular ducts 

 being only 12 /x long. Larvae of parvum have one trilocular pore 

 near each spiracle instead of two near the posterior spiracle as in 

 mr/fv/w/u and nine dorsal 8-shaped pores instead of four as in 

 minmcidum.

(Fig. 48, H-O; pi. 9, D) 



Described by Kuwana and Cockerell in an article published by 

 Kuwana in 1909 (54, p. lo2) . 



Habit. — Living on the lower surface of leaves. 



Test of female. — Elongate ovoid, 1.6 mm. long, 1 wide; slightly convex dor- 

 sally, with a longitudinal median carina and faint transverse striations ; flat 

 ventrally; bright yellow, transparent, shiny, slightly punctate; marginal fila- 

 ments pale salmon; circular larval exit in margin. 



Adult female. — Elongate ovoid, 1.10 mm. long, So wide. 



Margin: 8-shaped pores in a single row terminating one-third length of an 

 apical seta from bases of setae, each pore with a short, sclerotized, tongue- 

 shaped projection on dorsal cd^o, posterior pores 8 u long and 5 wide, others 9 ,u 

 long and 5 wide, usually around a pore's length apart near anterior end and a 

 pore's width apart near posterior end; quinquelocular pores in a single row 

 terminating within 20 8-shaped pores from end of row, usually at leasl as 

 numerous as corresponding 8-shaped pores, but sometimes the row interrupted 

 anteriorly. 



Dorsal surface: Minute 8-shaped pores numerous; disk pores fairly numerous; 

 tubular ducts 24 n long. 



Ventral surface: Antenna short, with 2 setae as long as diameter of antenna: 

 beak apparently with 2 pairs of setae; spiracular bar fairly bread: a group 

 of 3 or 4 quinquelocular pores sometimes at spiracular opening, but in any 

 case with 2'-:;o quinquelocular pores extending from opening to body margin 

 in an irregularly single row; multilocular pores, with 10 loeuli. in 4 complete 

 and 4 interrupted rows, the posterior row with 10-12 pores, each of the other 

 complete rows with 4-9, and each of the interrupted rows with 4 or 5, the total 

 being approximately 36; 2 or 3 dark-rimmed 8-shaped pores each side of mouth
