name is suppressed. It was listed as a synonym of pnbricdwm by 

 Lindinger in 1912 (67. p. 360). 



Habit. — Living on twigs, sterns, and leaf pet! 



Test of female. — Usually broadly pyriform. posterior end slightly produced and 

 often upturned: 2-3.5 nun. long. L5-2.5 wide, usually -1.5-3 mm. long, 2-2.5 wide; 

 strongly convex dorsally. posterior tip flattened, flat or very slightly convex 

 ventrally; whitish, brownish, or pale yellowish, translucent to nearly opaque; 

 rather thick, slightly punctate: marginal and dorsal filaments whitish, the latter 

 in a conspicuous tuft along median line and sometimes scattered elsewhere, the 

 median dorsal filaments longer and the others shorter than the marginal, all 

 dorsal filaments tending toward arrangement in transverse rows, but this tend- 

 encv most apparent along median line : larval exit elongate elliptical, in margin. 



Adult female. — Broadly pyriform, 1.75-3.25 mm. long. 1.25-2.25 wide. 



Margin: 8-shaped pores mostly in a double or (for a short distance) in a 

 triple row. but posterior 15-32 pores usually in a single row. terminating one to 

 two times a pore's length from bases of apical setae. 16-18 ,u long and 10-12 wide,, 

 usually around a pore's length apart : the rows usually separated by a space equal 

 to a pore's width: quinquelacular pores usually in a double or irregularly triple 

 row (rarely in a crowded single row i in lateral area, but single at ends of row, 

 terminating 15-32 8-shaped pores from the posterior pair of 8-shaped pores, the 

 row usually interrupted for 3-25 8-shaped pores anteriorly ; cpiinquelocular pores 

 usually as numerous as 8-shaped pores at ends of row and two or three times as 

 numerous as 8-shaped pores between and outside of spiracular pore bands : disk 

 pores irregularly spaced dorsad of, and less numerous than. 8-shaped pores, either 

 terminating with the latter or extending to apical se:ae and continued anterior to 

 them near edge of anal opening: disk pores also ventrad of quinquelocular \ 

 terminating near apical setae, as numerous as those dorsad of 8-shaped per - 



Dorsal surface: 8-shaped pores in 5-7 transverse groups in median area, some- 

 times also in inconspicuous transverse rows between median groups and margin, 

 majority of median pores 16-18 u long and 12 wide, a few in median posterior 

 group and the majority of the others 12 ,u long and 8 wide, although some are 

 only S-10 ix long and 5-6 wide : minute 8-shaped pores numerous between median 

 8-shaped pores and margin, or absent if large 8-shaped pores are scattered be- 

 tween median groups and margin ; disk pores fairly numerous ; tubular ducts 

 40 /x long. 



Ventral surface : Antenna roughly circular, with 2 setae longer and 2-7 shorter 

 than diameter of antenna ; 0-3 quinquelocular pores near antenna : beak with 2 

 pairs of setae: spiracle with bar broad: a subcircular sclerotized area around 

 spiracular opening. 1-10 quinquelocular pores in sclerotized area and 30-60 (usu- 

 ally around 50, very rarely with less than 40 ) extending to margin in an irregu- 

 larly single to quadruple row. making a total of 34-70 in group and row combined : 

 multilobular pores, having 6-11 loculi. in 3 or 4 complete and 2-4 interrupted 

 rows, the anterior interrupted row anterior to posterior spiracles, posterior row 

 with 16-32 pores (usually 22-271. penultimate with 19-52 (usually 24-38), first 

 row anterior to penultimate with 9-51 (usually 23-33 i. next with 1-28 (usually 

 3—8), without other rows posterior to spiracles or with 1 or 2 additional rows 

 each with 1-10 (usually 2-5). row anterior to posterior spiracles with 1-12 (usu- 

 ally 3-7). making a total of 55-180 (usually 95-125) : 4-10 dark-rimmed 8-shaped 

 pores each side of mouth parts, some scattered on anterior end and others 

 arranged in 6 or 7 transverse rows on abdomen: submarginal 8-shaped pores in 

 an irregularly double to quadruple row terminating near anterior complete row 

 of multilocular pores, the row broken up into groups which are placed irregularly. 

 so that there are no pores opposite some marginal 8-shaped pores and 1-5 opposite 

 others: 1-6 disk pores in each spiracular quinquelocular pore band and usually 

 1-4 in each row of multilocular pores except the anterior row, sometimes occurring 

 between fourth and anterior rows of multilocular pores : submarginal setae in a 

 complete row terminating opposite the penultimate pair of marginal 8-shaped 

 pores; 1-3 setae in each of posterior 3 rows of multilocular pores and - 

 fourth row. 



Apex of abdomen: Usually slightly concave: setae, apical 1c 128 Long, inter- 

 apical 32-40 u long, dorsal 24-36 u long, inner ventral usually 6-9 a lore (12 - 

 long on 1 half of type specimen), intermediate ventral 8-12 a long, outer ventral 

 10-16 u. long: anal ring with 6 setae - long (usuall3 vs - 2 and with 



approximately 46 pores: ventral surface of apex heavily sclerotized about inner 

 ventral setae, the surrounding area lightly sclerotized in dentate rows.
