Africa, intercepted at Washington, D. C, H. L. Sanford, February 

 23, 1935, holotype and paratypes. 



This species resembles tramsversum, but differs from it in several 

 characters, the most important being the terminating point of the 

 marginal quinquelocular pores, which is much farther from the pos- 

 terior pair of marginal 8-shaped pores than in transversum, the pres- 

 ence of 22 to 32 pores in each spiracular pore band instead of 9 to 16, 

 more than 100 multilocular pores instead of less than 90, and a dorsal 

 seta on the apex of the abdomen. 



Asterolecanium euryopis Fuller 



(Fig. 22, M; fig. 23, B-J ; pi. 1, D) 



Described and named in 1899 (38, pp. 93-95; 39, p. 818). 



Habit. — Living on bark. 



Test of female. — Practically circular, posterior end slightly produced and 

 slightly to distinctly upturned ; 2-2.5 mm. in diameter ; strongly convex dorsally, 

 flat ventrally ; clear yellow, transparent, fairly thin ; marginal filaments whitish, 

 varying in length, and not differentiated from dorsal filaments, which are so 

 numerous that test cannot be seen in unrubbed specimens, and which are some- 

 times replaced by a thin sheet of glassy material at any one spot although with 

 many distinct filaments present ; elliptical larval exit in margin. 



Adult female. — Shape similar to that of test, about 1.5-2 mm. in diameter. 



Margin : 8-shaped pores in a single row terminating around five times the 

 length of apical seta from setal bases, the row poorly defined, not distinct from 

 dorsal pores, and particularly difficult to observe at anterior end ; pores slightly to 

 deeply invaginated, 20^28 /a long and 12-13 wide, the posterior pores as small as 

 any, one to three times a pore's length apart ; disk pores on either side, or at 

 end, of 8-shaped pores, terminating fairly close to apical setae, as numerous as 

 8-shaped pores. 



Dorsal surface : 8-shaped pores scattered, and very numerous except close to 

 posterior end, the majority distinctly invaginated, 20-28 m long and 12-20 wide ; 

 minute 8-shaped pores absent ; disk pores rather sparse ; tubular ducts 46 n long. 



Ventral surface : Antenna normally a dome-shaped stub with 3 setae nearly 

 as long as diameter of antenna ; beak with 2 pairs of setae ; spiracle with bar 

 greatly enlarged at inner end, with atrium not enlarged and not containing pores, 

 but derm surrounding opening and adjacent to bar sometimes sunken, pocket- 

 like, and filled with quinquelocular pores, 75-125 pores extending from opening 

 to body margin, either in an even band or in an irregular band which is broad 

 near opening, then narrows and then broadens to as much as 6-12 pores wide ; 

 multilocular pores, totaling 145-170, with 6-10 (usually 10) loculi, in 4 complete 

 and 1-3 interrupted rows, the posterior row with 26-31, penultimate with 42-55, 

 next with 49-56, next with 13-24, and each of interrupted rows with 1-4 ; a loose 

 group of 10-15 dark-rimmed 8-shaped pores each side of mouth parts, a few 

 scattered on anterior end, and many in lateral area arranged in rather indffinite 

 longitudinal rows 2 or 3 pores wide, and extending across median area in 5 or 6 

 transverse rows ; submarginal 8-shaped pores in a single row terminating near 

 first row anterior to penultimate row of multilocular pores, well removed from 

 margin, slightly less numerous than marginal 8-shaped pores ; submarginal setae 

 absent ; 3 pairs of setae in posterior row of multilocular pores and 1 pair in 

 penultimate row. 



Apex of abdomen : Notch present ; setae, apical 18-20 fi long, interapical 12.6 

 fj. long, dorsal 9-10.8 n long (close to, and outside apical, sometimes missing on 

 1 side of body), inner ventral 5.4 /m long, intermediate ventral 5.4 jj, long, outer 

 ventral 7.2-9 fi long ; anal ring with 6 setae 72-80 m long, with around 40 pores 

 tending toward arrangement in an inner row of 6 or 8 and an outer one of around 

 30; ventral surface of apex sclerotized close to margin of notch. 



Larva. — Nearly elongate elliptical, posterior end narrowed. 



Margin : 8-shaped pores 28 in number, axis of the posterior pair transverse, 

 of the others slightly diagonal or longitudinal ; 2 or 3 setae at anterior end 

 (sometimes as nearly submarginal as marginal). 



Dorsal surface : 8-shaped pores, totaling 44-48, in a submedian row of 9 or 

 10 and a submarginal row of 13 or 14, on each half of body, the submarginal
