THE SCALE INSECT GENUS ASTEROLECANIUM 39 



Apex of abdomen : Slightly concave. lobes indicated; setae, apical ~G a long, 

 interapical 9 n long, intermediate ventral (close to margin) 4 /x long, outer ventral 

 7.2 u long ; anal ring with 6 setae, each 28 /j. long, also with an inner row of 6 and 



an outer row of 14 pores, possibly divided on dorsal side. 



Larva. — Elliptical. 



Margin: With 28 8-shaped pores, the anterior 3 pairs slightly larger than 

 others, axes of the posterior 6 pairs diagonal, the others longitudinal ; apparently 

 3 pairs of setae anteriorly. 



Dorsal surface: 8-shaped pores in a submedian row of 8 on each half of body, 

 anterior pore largest and practically equal in size to marginal pores of same 

 segment, the others as long as the width of marginal pores of same segments ; 

 disk pores in lateral area. 



Ventral surface : Antennal setae. I. 1 : IV. 1 very short : 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 on outer margin near 

 center, tarsus 1 each on inner and outer margins : tibia onedialf length of tarsus ; 

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

 abdomen, apparently 3 pairs of submarginal larger setae anteriorly; 1 pair of 

 setae between antennae and mouth parts. 



Apex of abdomen : Slightly concave : setae, apical 36 jjl long, interapical 9 /j, 

 long, intermediate ventral (rather close to median line) 2 a long, outer ventral 

 3.6 fj. long: anal ring with 6 setae 14 y. long, and with an inner row of 6 and an 

 outer row of 12 pores, possibly divided on dorsal side. 



Data. — Described from unmounted material, seven mounted females, 

 and three mounted larvae on Bambusa sp., Antipolo. Luzon. Philippine 

 Islands. A. S. Hitchcock. June 9. 1921. U. S. X. H.. holotype and para- 

 types ; unmounted specimens, four mounted females, and five mounted 

 larvae on Bambusa blumecma^ Balic-Balic. Luzon. Philippine Islands, 

 A. Loher. June 20. 1893. U. S. X. H.. paratypes. 



Closely related to pseudomilums, but adults differ from those of 

 pseudomiliaris in having multilocular pores, and larvae of acutulum 

 have one instead of two pores near the posterior spiracle. 



Asterolecaxium adjunctum, new species 



(Fig. 3, L-Z; pi. 9, DD) 



Habit. — Living on twigs. 



Test of female. — Elongate, tapering toward posterior end. posterior tip broken 

 off, margin indented by growth against hairs on twigs: broken tesr 0.95 mm. 

 long. 0.5 wide; strongly convex dorsally. Mat ventrally; bright yellow, trans- 

 parent, rather thick, shiny, smooth: marginal and dorsal filaments rubbed off; 

 larval exit absent from broken test. 



Adult female.— Elongate, 0.9 mm. long. 0.5 wide. 



Margin : 8-shaped pores in a single row terminating two-thirds the length of an 

 apical seta from seta! bases, each pore with a conspicuous, sclerotized, tongue- 

 shaped projection on dorsal edge, posterior pores u long and 4 wide, the others 

 gradually increasing in size anteriorly to 9 m long and 5 wide, approximately a 

 pore's length apart: quinqueloeular pores in a single row. interrupted at anterior 

 end opposite about 10 8-shaped pores, and terminating about 8 8-shaped pores 

 from the posterior pair of those pores, about as numerous as 8-shaped pores at 

 ends .,f row. slightly more numerous before ends of row, and at least twice as 

 numerous as 8-shaped pores near spiracular pore bands. 



Dorsal surface: 8-shaped pores somewhat scattered but tending toward ar- 

 rangement in Longitudinal rows, fairly numerous, 3.6 7.5 u Long and 2.5 5.5 wide. 

 with the majority of lateral and submarginal pores 4r-5 u Ion- and J .":, wide 

 and majority of submedian pores T.ii u Long and 4 wide: minute B-shaped pores 

 very sparse, present only in posterior median area; disk pores fairly numerous; 

 tubular ducts ~S.\ u Long. 



Ventral surface: Antenna roughly conical, with 1 or possibly 2 setae: beak 

 apparently without setae; spiracle with bar expanded at inner end, with atrium 

 Slightly enlarged and containing 2-4 quinqueloeular pores, and with 9 or 10 

 similar pores extending to body margin in an irregularly single or double row:
