each side of beak and a few on abdomen tending toward arrangement in transverse 

 rows ; submarginal 8-shaped pores in a double row, the pores of outer row about 

 twice as numerous as those of inner row and about half as numerous as the 

 marginal 8-shaped pores with which they terminate ; 5 pairs of submarginal 

 setae on abdomen, the posterior pair about two-thirds length of an apical seta 

 from bases of apical setae, 7 setae arranged in 2 transverse rows posterior to 

 genital opening, 2 setae anterior to opening, 2 anterior to those. 



Apex of abdomen: Lobes barely indicated; setae, apical (tips broken) 52 /* 

 long, interapical 8 fi long, intermediate ventral 5 n long, outer ventral 6 m long ; 

 anal opening ventral, close to body margin, circular, its margin membranous. 



La rva.— Elliptical. 



Margin : With 28 8-shaped pores, posterior pair smallest, the others gradually 

 larger to the anterior pore, which is twice the size of the posterior one, axes 

 of all longitudinal; 3 pairs of setae anteriorly. 



Dorsal surface: 8-shaped pores in a submedian row of 2 (1 near each end 

 of body) and a lateral row of 8, on each half of body, about as long as the 

 width of a posterior marginal pore ; a few disk pores between lateral and marginal 

 8-shaped pores. 



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

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

 but not elongate, with 2 pairs of setae at tip and 1 pair in median area ; spiracle 

 with bar very small, and with 1 trilocular and 1 quinquelocular pore ; leg setae, 

 coxa 4, femur 1 on inner margin near base and 1 each on inner and outer margins 

 near center, tarsus 1 each on inner and outer margins ; tibia one-half as long 

 as tarsus ; 9 pairs of submarginal 8-shaped pores ; apparently 6 pairs of sub- 

 marginal minute setae on abdomen, 3 pairs of submarginal larger setae at 

 anterior end ; 2 pairs of setae near antennae. 



Apex of abdomen : Lobes barely indicated ; setae, apical 40 /j. long, interapical 

 8 fi long, intermediate and outer ventral each 3 /* long ; anal opening a short, 

 narrow incision in margin ; anal tube sclerotized, larger at inner than at outer 

 end ; anal ring a sclerotized band. 



Data. — Described from 3 tests, 1 mounted female, and more than 

 50 mounted larvae on Schizostachyum sp., Bikal, Philippine Islands, 

 F. A. McClure, October 25, 1925, holotype and paratypes. 



This species is most unusual in lacking a well-defined bar on the 

 spiracle of the adult female. 



Asterolecanium singulare, new species 



(Fig. 64, F-Q; fig. 65, A; pi. 9, B) 



Habit. — Living on bark. 



Test of female. — Somewhat elliptical, posterior end slightly narrowed; 1.6-1.75 

 mm. long, 1.25-1.35 wide ; slightly convex dorsally, flat ventrally ; pale brownish 

 yellow, transparent, punctate, shiny ; marginal filaments fragmentary, apparently 

 same color as test ; elliptical larval exit in dorsal surface at margin. 



Adult female. — Nearly elliptical, posterior end narrowed, produced, and truncate ; 

 1.6 mm. long, 0.95 wide. 



Margin :: 8-shaped pores in a single row terminating at produced area of 

 abdomen, individual pores measuring 11-12 fi long and 8 wide, usually a pore's 

 length apart ; quinquelocular pores in a single row terminating with the 8-shaped 

 pores, 2-5 (usually at least 3) near each 8-shaped pore. 



Dorsal surface: Minute 8-shaped pores numerous; disk pores rather sparse; 

 tubular ducts 32 fi long. 



Ventral surface : Antenna globular, with 2 setae slightly longer, and 3 much 

 shorter, than diameter of antenna ; beak with 3 pairs of setae ; spiracle with 

 bar fairly slender, slightly expanded at inner end, atrium enlarged, bag-shaped, 

 and containing 11-13 quinquelocular pores, 13-16 similar pores extending from 

 spiracle to body margin in an irregularly double or triple row : multilccular 

 pores, totaling 76, and with 9 or 10 loculi, apparently arranged in 4 complete and 

 4 interrupted rows, the posterior row with 26, penultimate row with 17, next with 

 13, anterior complete row with 4, and each of interrupted rows with 4 : a group 

 of 10-12 dark-rimmed 8-shaped pores each side of beak, a few scattered on anterior 

 end, and many posterior to beak, some scattered in lateral area and others tending 

 toward arrangement in at least 6 transverse median rows ; submarginal 8-shaped
