Margin: 8-shaped pores in a single row interrupted at anterior end for a 

 space equivalent to that occupied by about 5 pores and terminating length of 

 an apical seta from bases of setae, posterior pores 8 /* long and 4.5 wide, the 

 others 12 /j. long and 6 wide, around a pore's width apart; quinquelocular 

 pores in a single row starting slightly posterior to antennae and ending slightly 

 nearer to the posterior pair of 8-shaped pores than to the posterior spiracular 

 pore bands, a little more numerous than corresponding 8-shaped pores. 



Dorsal surface : Minute 

 long; dorsal tubes present. 



Ventral surface: Antenna short, crater like at end. with 2 setae longer than 

 diameter of antenna ; beak without setae ; spiracle with bar fairly broad, atrium 

 slightly enlarged and containing 3 or 4 quinquelocular pores, 16-21 similar 

 pores extending from spiracle to body margin in an irregularly double row; 



1 or 2 dark-rimmed 8-shaped pores each side of mouth parts and a few in 

 lateral area of abdomen ; submarginal 8-shaped pores in a single row terminat- 

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

 marginal 8-shaped pores ; 4 pairs of submarginal setae on abdomen, the posterior 

 pair slightly behind the posterior pair of marginal 8-shaped pores; 1 pair of 

 setae posterior and 1 pair anterior to genital opening. 



Apex of abdomen : Notch present ; lobes indicated ; setae, apical 54 \i long, 

 interapical 5.4 //. long, intermediate ventral 3-3.6 /* long, outer ventral 5.4 ^ long : 

 anal ring with 6 setae 27 n long and with an inner row of 6 and an outer row of 

 14 pores, apparently not divided. 



Larva. — Elongate elliptical. 



Margin : With 28 8-shaped pores, the posterior, penultimate, ninth from 

 posterior, next to anterior, and anterior pairs fairly large and nearly uniform 

 in size, the others also uniform in size and as long as the width of the larger 

 pores, axes of the posterior 6 pairs slightly diagonal or longitudinal, of the 

 others longitudinal ; 3 pairs of setae anteriorly. 



Dorsal surface : A submedian row of 5-8 8-shaped pores and 1 lateral pore, 

 on each half of body, smallest pores slightly larger than smallest marginal pores 

 and largest pores slightly smaller than largest marginal ; 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-fourth length of antenna apart ; beak setae, 

 2 pairs apical, 1 pair median ; spiracle with 1 trilocular and 1 quinquelocular pore : 

 leg setae, coxa 4, femur 1 on inner margin near 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, 2 pairs of submarginal larger setae at anterior end ; 



2 pairs of setae between antennae and mouth parts. 



Apex of abdomen : Notch present : setae, apical 40 (j. long, interapical 9 ix long, 

 intermediate ventral 2 n long, outer ventral 3 \i long; anal ring with 6 setae 9 fx 

 long and apparently with 6 pores. 



Data. — Described from 1 test destroyed in mounting, 1 mounted 

 female, and 18 mounted larvae from Dinochloa sp., Naam-fung, 

 Hainan, Kwangtung, China, F. A. McClure, 1929, holotype and 

 paratopes. 



This species is most closely related to bambmicola, but differs from 

 it in having the marginal row of 8-shaped pores terminating the 

 length of an apical seta from the bases of the apical setae, in having 

 16 to 21 instead of 60 to 100 quinquelocular pores in each spiracular 

 band, and in lacking a group of 10 to 11 setae posterior to the genital 

 opening, as well as in less conspicuous characters.

 palm from Mauritius. 



Habit. — Living on the upper surface of leaves. 



Test of female. — Lanceolate, 1.5-2.5 mm. long, 0.75-1 wide ; flat dorsally. 

 with a faint longitudinal median carina ; flat or slightly convex ventrally ; bright
