whitish ; dorsal filaments either absent or 1-10 on median line, whitish ; elliptical 

 larval exit in margin. 

 Adult female. — In shape similar to test, 0.7-0.9 mm. long. 0.3 wide. 

 Margin: 8-shaped pores in a single row terminating two and a half times 

 the length of apical seta from seta! bases, posterior pores 6-7 m long and 4 

 wide, others 8 /j. long and 4.5 wide, usually a pore's length apart; cpi in quel ocular 

 ' pores as numerous as corresponding 8-shaped pores and arranged in a single 

 • row extending from slightly anterior to anterior spiracular pore bands i" a 

 point beyond posterior spiracular pore bands, which is nearer to the posterior 

 spiracular pore bands than to the posterior pair of 8-shaped pores. 



Dorsal surface: 8-shap .1 pores absent, or 1-10 such pores on median line, 

 these 10-12 fi long and 6-8 wide; minute 8-shaped pores fairly numerous; disk 

 pores sparse; tubular ducts 24 u long: dorsal tubes present. 



Ventral surface : Antenna short, with '1 setae longer than diameter of antenna ; 

 beak without setae; spiracle with bar very short, and atrium slightly enlarged 

 and containing 1 or 2 quinquelocular pores. 4 or 5 similar pores extending to 

 body margin in a single row : 2 dark-rimmed 8-shaped pores each side of beak,. 



1 or 2 anterior to mouth parts, and 2-4 in each of 2 transverse rows anterior 

 to genital opening; submarginal 8-shaped pores in a single row terminating 

 near the posterior pair of marginal 8-shaped pores, nearly as numerous as 

 marginal 8-shaped pores: 6 pairs of submarginal setae on abdomen, the posterior 

 pair the length of apical seta from bases of apical setae ; 1 pair of setae posterior 

 to genital opening and 1 pair anterior. 



Apex of abdomen : Notch present ; lobes indicated : setae, apical 40 \i long r 

 interapical 8 m long, inner ventral 5.2 ft long, outer ventral 6 /x long : anal ring 

 with G setae 28-30 \x long and an inner row of 6 and an outer row of 12 pores, 

 divided on dorsal side and tending toward division on ventral. 



Larva. — Elliptical. 



Mai gin: With 2S 8-shaped pores, the posterior 6 pairs slightly smaller than 

 next 7. anterior pair slightly the largest, axes of the posterior 6 pairs slightly 

 diagonal, of the others longitudinal: 3 pairs of setae at anterior end. 



Dorsal surface: 8-shaped pores in a submedian row of 11 on each half of body, 

 gradually increasing in size from posterior to anterior end of row, all distinctly 

 larger than marginal pores of same >egments : disk pores in lateral area. 



Ventral surface: Antennal setae, I, 1; IV, 1: V. 1: VI. 2 long. 2 stout, 3 

 fairly stout. 1 slender ; antennal bases one-third length of antenna apart : beak 

 setae. 2 pairs apical. 1 pair median: anterior spiracle with 1 trilocular pore, 

 posterior spiracle with 1 trilocular and 1 quinquelocular pore; leg setae, coxa 

 3, femur 1 on inner margin near base and 1 on outer margin near center, tarsus 



2 on inner and 1 on outer margin ; tibia one-half as long as tarsus : 9 pairs of 

 submarginal 8-shaped poies; G pairs of submarginal minute setae on abdomen, 

 1 pair of submarginal larger setae anteriorly : 2 pairs of setae between antennae 

 and mouth parts. 



Apex of abdomen : Notch present ; setae, apical 27 ll long, interapical 7.2 n 

 long, inner ventral 3 y. long, outer ventral 3.6 /j. long ; anal ring with 6 setae 9 m 

 long and with an inner row of 6 and an outer row of 6-S pores, divided on 

 dorsal side and tending toward division on ventral. 



Data. — Described from unmounted material and the following 

 mounted specimens : Four females and 4 larvae on bamboo. Hong 

 Kong. China. G. Compere. Compere Xo. 242; 19 females and 17 larvae 

 on bamboo. Hong Kong. China. C. W. Howard. April 2G and August 

 11, 1030. Xos. 176 and 191; 1 female, Tung Heung near Kwong Xing, 

 Kwangtung. April 25. 1925. and 4 females and 3 larvae. An Tsui. Foo 

 Chiu Haang, Kwangsi, November 5, 1928 (including holotype), 

 collected by F. A. McClure in China on Barmbusa. 



Similar to pseudoJonceoJatum, but differing in being smaller, in 

 not having two quinquelocular pores posterior to the genital opening, 

 and in its shorter apical setae. Furthermore, the larva has only 

 three setae on each coxa whereas there are four in pseudolcanceolatwm. 



Specimens from stems either have no dorsal 8-shaped pores or only 

 one to three, whereas specimens from leaves have at least five and 

 usually nine such pores.
