the antennae; 7 pairs of minute submarginal setae on abdomen, 1 pair of sub- 

 marginal larger setae at anterior end ; 2 pairs of setae between antennae and 

 mouth parts. 



Apex of abdomen : Setae, apical 63 n long, sometimes one 1 or 2 fi long inside 

 or outside apical ; anal opening in margin, circular ; anal tube very short, slightly 

 sclerotized; anal ring a sclerotized band, with 1 or 2 setae 2-3 //. long, or with 

 2 indefinite setal bases. 



Data. — Described from the following material : One poor mounted 

 female on Quercus lusifanica. probably from Spain, U. S. N. H., para- 

 type ; unmounted material, 2 mounted females, and 13 mounted larvae 

 on Quercus pubescens, Laaerberg, Austria, determined as quercicola 

 by Low, loaned by M. Beier, holotype and paratypes. 



Closely related to repagnans, but differing from it in having mar- 

 ginal quinquelocular pores. 



Asterolecanium rubrocomatum Green 



(Fig. 60, E-J; pi. 6, J) 



Described in 1909 {Jp2, p. 316). 



Habit. — Living on both surfaces of leaves. 



Test of female. — Nearly elongate elliptical, posterior end either rounded or 

 rather pointed ; 1.5-2 mm. long, 0.75 wide ; slightly convex dorsally. flat ventrally : 

 brownish yellow, transparent, thin, shiny, punctate ; marginal filaments yellowish 

 to pinkish, slightly longer at anterior end than elsewhere ; dorsal filaments 

 rubbed off ; larval exit apparently a slit in margin. 



Adult female. — In shape similar to test, 1.4-1.8 mm. long, 0.6 wide. 



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

 apical seta from setal bases, 14 m long and 8 wide at anterior end, 12 fi long and 

 8 wide elsewhere, around a pore's width apart ; quinquelocular pores mostly in a 

 single row, but in an irregularly double row at a few points, usually terminating 

 at a point near the fourth to the fourteenth 8-shaped pore from end of row, 

 usually around three times as numerous as corresponding 8-shaped pores, but 

 sometimes no more numerous than the latter posteriorly. 



Dorsal surface : 8-shaped pores in 6-8 transverse rows in median and sub- 

 median area, and in a single or double submarginal row, each of 4 transverse 

 rows with 10-12 pores and each of the others with 2 or 3, the pores in posterior 

 and penultimate rows 6-7 \i long and 4 wide, the majority of the others 8-10 /j. 

 long and 6 wide but a few 12 /x long and 8 wide ; around 26 submarginal pores 

 spaced at fairly uniform intervals, the posterior pore 14 (i long and 8 wide, its 

 axis usually transverse, the other submarginal pores 8-10 ^ long and 5-6 wide 

 and their axes usually longitudinal : minute 8-shaped pores numerous ; disk pores 

 rather sparse; tubular ducts 32 p long; dorsal tubes present. 



Ventral surface : Antenna conical, sometimes slightly sunken in derm, with 

 2 setae longer than diameter of antenna ; beak without setae ; spiracle with 

 bar fairly broad, atrium enlarged and containing 8-14 quinquelocular pores, 

 10-15 similar pores extending from spiracle to body margin in a single or 

 irregularly double row ; legs represented by 3 pairs of fairly small to stout 

 claws each in a circular sclerotized area, anterior claws smaller than the others, 

 and middle claw sometimes smaller than posterior one : multilocular pores, 

 with 9 or 10 loculi, in 4 complete and 4 or 5 interrupted rows, the posterior row 

 with 8-13 pores, penultimate row with 16-21, next with 7-11, anterior complete 

 row with 3-8, and each of interrupted rows with 1-3, the total ranging from 

 45-61 ; 5 or 6 dark-rimmed 8-shaped pores each side of beak, some scattered 

 anterior to mouth parts, a few in lateral area of abdomen, and others arranged 

 in 3 transverse rows near posterior end of abdomen ; submarginal 8-shaped pores 

 mostly in a single row (sometimes irregularly double near posterior end) ter- 

 minating near the penultimate row of multilocular pores, 1 pore opposite each 

 marginal 8-shaped pore; 8 pairs of submarginal setae posterior to anterior 

 spiracular pore bands, the posterior pair near the posterior or penultimate pair 

 of marginal 8-shaped pores ; 1 pair of setae in each of the posterior 3 rows of 

 multilocular pores. 



Apex of abdomen ; Notch present ; lobes indicated : setae, apical 52-56 \x long, 

 interapical 4.2 n long, outer ventral 4 /u, long: anal ring with 2 setae apparently
