as numerous as 8-shaped pores, situated dorsad of them and terminating near the 

 posterior pair. 



Dorsal surface: Minute 8-shaped and disk pores numerous; tubular duets 

 36 fi long: dorsal tubes present. 



Ventral surface: Antenna rough, dome-shaped, with i' setae Longer and 2 

 shorter than diameter of antenna: beak without setae: spiracle with bar broad 

 and with wrinkles in derm around opening: 12-25 quinquelocular pores extending 

 from spiracle to body margin in an irregularly double or triple row; multilocular 

 pores in 8 rows. 5 or 6 of which are complete and 2 or :; interrupted, posterior 

 row with 14 pores in each of the 2 available specimens, penultimate 18 and 25. 

 respectively, next 15 and IS, next 9 and 11, next 5 and 8, next 2 and 8, next 2 and 

 4, and anterior row with 2. the individual pores with 8-10 loculi ; 1 or 2 dark- 

 rimmed 8-shaped pores each side of beak, a few scattered on anterior end, some 

 arranged roughly in a single longitudinal lateral row and in 4 transverse rows 

 among multilocular pores ; submarginal 8-shaped pores in a single row termi- 

 nating near the posterior row of multilocular pores, usually about half as 

 numerous as marginal 8-shaped pores: >; pairs of submarginal setae on abdomen, 

 the posterior pair near the third posteriormost pair <>f marginal 8-shaped pores; 



1 pair of setae in each of the posterior 4 rows of multilocular pores. 



Apex of abdomen : Notch present : setae, apical 28-30 /j. long, interapical 7.2 and 

 12.0 fi long, respectively, in the 2 specimens studied, outer ventral 5.4 and 9 u 

 long : anal ring with 6 setae 30-34 u long and with an inner row of and an 

 outer one of an indeterminable number of pores, divided on dorsal side and 

 tending toward division on ventral. 



Larva. — Elliptical. 



Margin : With 28 8-shaped pores, the posterior pair slightly larger than next 

 5 pairs and about the same size as the sixth, which is slightly larger than the 

 next 6 pairs, anterior pair slightly larger than the posterior pair: axes of the 

 posterior 6 pairs longitudinal or slightly diagonal, of the others longitudinal; 



2 pairs of setae anteriorly. 



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

 about three-fourths the size of marginal pores of same segments; disk pores 

 in submarginal area and a few in lateral area. 



Ventral surface : Antenna indistinctly 6 segmented ; antennal setae, I. 1 : IV, 

 1: V. 0: 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 ; spiracle 

 with 1 quinquelocular pore: leg setae, coxa 4. femur 1 on inner margin at base 

 and 1 each on inner and outer margins near center, tarsus 2 on inner and 1 

 on outer margin : tibia one-half as long as tarsus : 9 pairs of submarginal 8-shaped 

 pores; 6 pairs of submarginal minute setae on abdomen. 3 pairs of submarginal 

 larger setae at anterior end ; 1 pair of setae between antennae and mouth parts. 



Apex of abdomen: Notch present: setao. apical 40 m long, interapical 12.6 m 

 long, outer ventral 3.6 /j. long: anal ring with 6 setae apparently 4 ,u long, 

 apparently without pores. 



Male nymph. — Antenna 10-segmented : 5 segments of abdomen each with a 

 seta dorsally on lateral margin; each lobe area with 1 short and 2 very short 

 setae: other characters indeterminable. 



Data. — Redescribed from one mounted female and one male nymph 

 on Arundinaria sp.. Naam Kwan Shan, Sheung Pino-. Lung Moon 

 district. Kwangtung. China. F. A. McClure, April 28, 1931, and one 

 test, one mounted female, and one mounted larva on bamboo. Nagasaki. 

 Japan. I. Kuwana collector, from E. E. Green, possibly type. 



The specimen from China is slightly smaller, and has fewer quin- 

 quelocular and multilocular pores and shorter interapical and ventral 

 setae than the specimen from Japan. The specimen from Japan is 

 doubtless from the type material, though it is not so labeled.

 (Fig. 40, G-M ; fur. 4t. .4 ; pi. S, J) 



Habit. — Living on bark. 



Test of female. — Broad elliptical, 1.5-1.75 mm. long. 1.25-1.5 wide: convex 

 dorsally. with a longitudinal median and a submarginal carina, usually with 

 transverse striatums crossing earinae: tlat vent rally : light brownish, transparent.
