pink on pink test, slightly longer at ends than elsewhere ; larval exit a slit in 

 margin. 



Adult female. — Elongate elliptical, 2.5 mm. long, 1.4 wide. 



Margin : 8-shaped pores in a single row usually terminating less than a 

 posterior pore*s width from bases of apical setae, the posterior pair of pores 

 14-15 fi long and 7.2 wide, next 10-15 pairs 15-16 ll long and 8 wide, the remainder 

 16.2-18 fi long and 9 wide, all nearly contiguous ; quinquelocular pores mostly in 

 a single row but sometimes crowded so as to make the row double here and 

 there, terminating at or near the posterior pair of 8-shaped pores, 1 opposite 

 each 8-shaped pore near end of row, more numerous elsewhere, there being 

 usually 2, and sometimes 3 or 4, opposite each 8-shaped pore from a point 

 slightly posterior to posterior spiracular pore bands to near antennae, and 

 usually 2 opposite each 8-shaped pore at anterior end ; disk pores dorsad of, 

 and somewhat less numerous than, 8-shaped pores, terminating near the posterior 

 or penultimate pair of those pores. 



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

 tubular ducts 44 /x long ; dorsal tubes present. 



Ventral surface: Antenna dome-shaped, with 2 setae slightly longer and 2 

 much shorter than diameter of antenna ; 1-8 quinquelocular pores between 

 antenna and margin ; beak without setae ; spiracle with bar rather broad, a 

 sclerotized area extending around opening and 2-8 quinquelocular pores on 

 edge of opening, 39—75 similar pores extending from spiracle to body margin in 

 a row 2-6 pores wide; multilocular pores having 5-10 loculi (usually at least 

 6) in 2 rows, each with 3-6 pores ; 1-4 dark-rimmed 8-shaped pores each side 

 of beak, some scattered in a wide, irregularly double row entad of submarginal 

 area (except near posterior end), and others arranged in 2 or 3 sparse, transverse 

 rows near posterior end of abdomen ; submarginal 8-shaped pores in an irregu- 

 larly single row terminating near posterior row of multilocular pores, nearly 

 as numerous as marginal 8-shaped pores ; 7 pairs of submarginal setae on abdomen, 

 the posterior pair near the fourth posteriormost pair of marginal 8-shaped pores ; 

 1 pair of setae in posterior row of multilocular pores, 1 pair in anterior row, 



1 pair anterior to these, and a pair sometimes anterior to the last. 



Apex of abdomen : Notch small ; setae, apical 23.4-27 fi long, interapical 9 ft 

 long, inner ventral 4-6 xi long, outer ventral 7.2-9 fi long (actually anterior to 

 posterior marginal 8-shaped pore) ; anal ring with 6 setae 32.4-36 ix long, and 

 with an inner row of 6 and an outer row of apparently 14 pores, apparently tending 

 toward division on dorsal side ; ventral surface of apex sclerotized on margin. 



Larva. — Nearly elongate elliptical, posterior end narrowed. 



Margin : With 28 8-shaped pores, anterior pair distinctly the largest, the next 

 pair smaller than anterior pair but slightly larger than the others, axes of all 

 longitudinal ; 3 pairs of setae anteriorly. 



Dorsal surface : Disk pores in submarginal and lateral areas. 



Ventral surface: Antennal setae, I, 1 : IV, 1 ; V, ; 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 basal ; spiracle with 1 trilocular 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 ; 7 pairs of submarginal minute setae on 

 abdomen, 2 pairs of submarginal larger setae at anterior end ; 1 pair of setae 

 between nntennae and mouth parts. 



Apex of abdomen: Notch minute; setae, apical 72 ll long, interapical 18 ll long, 

 inner ventral 2 ll long, outer ventral 5.4 ll long; anal ring with 2 setae apparently 

 2.5 ll long, and four 5.4 ll long. 



Data. — Described from the following material: One mounted 

 female on Amwlinaria amabilis, Koo Shui, Kwong Nino- district, 

 Kwangtung, China, F. A. McClure, March 24, 1929, paratype; three 

 unmounted specimens, three mounted females, pnd eight mounted 

 larvae on bamboo, China, intercepted at Seattle, Wash., E. I. Smith, 

 May 26, 1937, holotype and paratypes. 



This species is rather similar to subdolum.
