growth against host, pores normally around 8 /* long and 5 wide and the majority 

 of them with a very short, sclerotized, tongue-shaped projection on dorsal edge. 

 Dorsal surface: Minute 8-shaped pores numerous: disk pores fairly numerous; 



tubular ducts 20 m long. 



Ventral surface: Antenna globular, with 2 setae slightly Longer than diameter 

 of antenna: beak apparently without setae: spiracular bar sometimes slightly 



expanded at inner end, more or less globose; 10-14 quincpielocular pores extending 

 from spiracle to body margin in a single row: multilocular pores, with 6-10 

 (usually 10) loculi, in 4 complete rows of 6-8 pores each: 1 or 2 dark-rimmed 

 8-shaped pores each side of beak and a few scattered in submarginal area: 

 submarginal 8-shaped pores in a single row terminating near the penultimate 

 row of multilocular pores, about one-half as numerous as corresponding marginal 

 8-shaped pores: submarginal setae in a complete row terminating nearer to apical 

 setae than to marginal 8-shaped pores: 2 pairs of setae in posterior row of multi- 

 locular pores. 1 pair in each of the other rows, and 1 pair cephalad of the 

 anterior row. 



Apex of abdomen : Lobe barely indicated : setae, apical 36-40 n long, interapicfll 

 2 n long, outer ventral 2.2 fj. long ; anal opening apical, circular, its margin 

 sclerotized. 



Larva. — Short elliptical. 



Margin: With 2s 8-shaped pores, posterior pores slightly smaller than the 

 anterior ones, axes of all longitudinal; 2 pairs of setae at anterior end. 



Dorsal surface : 8-shaped pores in a submedian row of 5 and a lateral row of 

 9, on each half of body, about one-half the size of marginal pores: disk pores 

 between submedian and lateral, and a few between lateral and marginal. 8-shaped 

 pores. 



Ventral surface: Antenna! setae. I. 1: IV. 1 : V. : VI, 2 long, 2 stout, appar- 

 ently 1 fairly stout. 2 slender; antennal bases nearly one-half length of antenna 

 apart: beak setae, apparently 4 pairs near tip: anterior spiracle with 2 quinque- 

 locular pores, posterior spiracle with none; leg setae, coxa 3. femur 1 on inner 

 margin near base, tarsus 1 each on inner and outer margins; tibia one-four:h 

 as long as tarsus: 9 pairs of submarginal 8-shaped pores: 7 pairs of submarginal 

 minute setae on abdomen, 5 pairs of submarginal larger <etae at anterior end; 

 2 pairs of setae between antennae and mouth parts. 



Apex of abdomen: Lobes barely indicated: setae, apical 36 n long, interapical 

 around 3.6 u long, outer ventral 2 /j. long; anal opening apical: anal tube short, 

 sclerotized, bulbous; anal ring a sclerotized, circular band with 2 setae 3.6 u 

 long. 



Data-. — Described from one unmounted specimen, two mounted 

 females, and one mounted larva from Pasama polystachya^ between 

 Takaw and Meh Soi, Chieng Mai Province. Siam. J. F. Rock. Janu- 

 ary 4. 1922, U. S. X. H.. liolotype and paratopes. 



The chief differentiating character between this species and 

 castaneae, the most closely related form, is the absence of marginal 

 quinquelocular pores in semisepultum and their presence in eastern

 (Fig. 63, F-0 ; pi. 8, D) 



Habit. — Living on leaves, twigs, and nuts. 



Test of female. — Longer than wide, ovoid, or irregular in outline, owing to 

 position on host, posterior end narrowed and produced; specimens on smooth 



surfaces 1.5-2 mm. long, 1-1.5 wide, specimens on rough surfaces around l.-" 

 mm. long. o.."-0.7o wide; flat to slightly convex dorsally, flat ventrally; pale 

 greenish or clear yellow, transparent, thin, smooth, shiny: marginal filaments 

 whitish to slightly pinkish: elliptical larval exit in margin. 



Adult female. — Varying in outline like test. 1-1.75 mm. long. 0.5-O.95 wide. 



Margin: In normal specimens B-shaped pores in a single row briefly inter- 

 rupted at produced area, but 4-10 pores beyond interruption, and terminating 

 one-half to the length of a pore from bases of apical setae, rarely extending 

 between setae, pores anterior to interruption 7 u long and 4 wide, the others 

 S-9 fj. long and 5 wide, approximately a pore's length apart ; owing to growth 

 against rough places on the host, the row sometimes with short or long inter
