Asterolecanium quadrisetosum, new species 



(Fig. 57, A-E; pi. 5, M) 



Habit. — Living on smooth bark, or in cracks and crevices, margin of test not 

 closely appressed to bark. 



Test of female. — Longer than wide, 1.25-1.75 mm. long, 0.75-1.25 wide ; convex 

 dorsally, occasionally with a faint longitudinal median carina, usually with a low 

 lateral carina, usually with faint transverse striatums which give the lateral 

 carinae the appearance of having minute tubercles on them ; slightly convex 

 ventrally ; brownish or clear yellow, transparent, rather thick ; marginal filaments 

 light brownish or whitish, very short ; circular larval exit ventral, close to margin. 



Adult female. — Longer than wide, 1-1.5 mm. long and 0.65 to 1 wide, posterior 

 end sometimes slightly produced. 



Margin : 8-shaped pores mostly in a double row but the posterior 4-7 pores 

 in a single row, terminating length of an apical seta from setal bases, the 

 posterior pores 9^10 ix long and 6 wide, the other 11-12 /j, long and 7 wide, intervals 

 between the pores within a row one to three times a pore's length, distance between 

 the 2 rows equal to at least a pore's length ; quinquelocular pores in a single row 

 terminating with the 8-shaped pores, one and one-half times as numerous as 

 8-shaped pores of nearer row ; disk pores occurring along 8-shaped pores of 

 dorsal row, and about one-third as numerous as those, terminating near the 

 posterior or penultimate pair of 8-shaped pores, irregularly spaced ; disk pores 

 also among quinquelocular pores and terminating at, or posterior to, the posterior 

 quinquelocular pores, irregularly spaced and less numerous than the qu'nquelocular 

 pores. 



Dorsal surface : Minute 8-shaped pores numerous ; 3 or 4 disk pores near 

 posterior end ; tubular ducts 36 jj. long. 



Ventral surface : Antenna blunt, with 2 setae slightly longer than diameter 

 of antenna ; beak with 3 pairs of setae; spiracle with bar expanded at inner end, 

 and with a sclerotized area extending around opening, atrium slightly enlarged 

 and containing 4-8 quinquelocular pores, 4-8 similar pores extending from 

 spiracle to body margin in a single row ; multilocular pores having 10 loculi, 

 arranged in 6 or 7 complete and 1 or 2 interrupted rows, posterior and penulti- 

 mate rows each with 9-12 pores, each of next 3 rows with 11-17, next with 8-14, 

 and the anterior 2 rows each with 3-7, the total number 75-94; dark-rimmed 

 8-shaped pores scattered loosely each side of beak and arranged in 5-7 transverse 

 rows posterior to beak ; submarginal 8-shaped pores in a single row terminating 

 near the fourth posteriormost pair of marginal 8-shaped pores, as numerous as 

 corresponding 8-shaped pores of nearer row ; submarginal setae in a complete 

 row terminating near the posterior pair of marginal 8-shaped pores ; 2 pairs of 

 setae in the- posterior row of multilocular pores and 1 pair in each of next 3 rows. 



Apex of abdomen : Notch present or absent ; lobes sometimes indicated ; setae, 

 apical 40 n long, interapical 12 //, long, intermediate and outer ventral 4-6 fi long ; 

 anal opening apical ; anal tube sclerotized in a narrow transverse band on dorsal 

 side and in a wider area on ventral side, inner end membranous and smaller 

 than outer ; anal ring with 4 setae 12 fi long and apnarentlv with 6 pores, divided 

 on ventral side ; ventral surface of apex sclerotized, wrinkled. 



Second stacre. — Resembling adult in share, but smaller ; margin with 8-shaped 

 pores in a single row terminating one-half length of an apical seta from setal 

 bases, quinquelocular pores in a row terminating before that of the 8-sbaned 

 pores, and present or absent at anterior end, as numerous as corresponding 

 8-shaned pores; ventral surface with atrium of sniracle slightly enlarged and 

 containing 1 quinquelocular pore, a faintly sclerotized area around opening, 1 

 quinquelocular pore between opening and body margin; apex of abdomen as in 

 adult but all setae about one-fourth shorter.
