ventral &-li\6 m long; anal ring with 6 setae 28-36 m long and with an inner row 

 of 6 and an outer row of 14 pores, divided od dorsal and ventral sides; ventral 

 surface of apex slightly sclerotized in dentate rows. 



' Second stage.— Resembling adult female, but smaller: margin with quinque- 

 locular pores less numerous than in adult; dorsal surface with 8-shapod pores 

 much less numerous than in adult, arranged in a median, and a sparse sub- 

 median. row: ventral surface with 2-4 quinquelocular pores in each spiracular 

 row. dark-rimmed S-shaped pores very sparse, U pair- of setae in median 

 abdominal area : apex of abdomen as in adult but all setae about one-fourth 

 shorter. 



Larva. — Ovoid. 



Margin: With 28 8-shaped pores, the posterior pair smallest, next 6 or 7 pairs 

 gradually increasing in size, and slightly smaller than the anterior 4 or 5 pairs, 

 axes <>f the posterior 6 pairs transverse, <>f the others longitudinal: 3 pairs of 

 setae at anterior end. 



Dorsal surface: 8-shaped pores in a submedian row of 9 and a lateral row of 

 10 or 11. on each half of body, 2 or 3 pores of lateral row outside a straight line 

 and suggestive of a submarginal row. posterior pores of each row the smallest, 

 the re-r gradually larger toward anterior end of row. the anterior 3 pores of 

 each row practically uniform in size, all pores about one-fifth to one-third smaller 

 than marginal pores of same segments; disk pores between submedian and lat- 

 eral, and between lateral and marginal, 8-shaped pores. 



Ventral surface: Antenna! setae. I. 2: IV. 1: V. 0: VI. 2 long, 2 stout. 3 fairly 

 stout. 2 slender: antennal bases about one-third length of antenna apart: beak 

 setae. 2 pairs apical. 1 pair basal; spiracle with 1 trilocular and 1 quinque- 

 locnlar pore: log 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-third as long as tarsus: 9 pairs of submarginal 8-shaped pores ; 

 9 pairs of submarginal minute setae, on abdomen and thorax. 2 pairs of sub- 

 marginal larger setae at anterior end: 2 pairs of setae between antennae and 

 mouth parts. 



Apex of abdomen: Notch present: lobes indicated: setae, apical 50 m long, 

 interapical 11 fx long, dorsal 3.G jj. long, intermediate and outer ventral 5.4 m long; 

 anal ring with 6 setae 20 m long and wi h an inner row of 6 and an outer row of 

 12 pores, divided on dorsal and ventral side< ; ventral surface of apex slightly 

 sclerotized in dentate rows. 



Test of male. — Nearly elliptical. 1.2 mm. long. 0.75 wide: slightly convex dor- 

 sally, with a rather broad, flat, longitudinal median carina, and sometimes with 

 a faint lateral carina: flat venrrally; greenish yellow: marginal filaments very 

 pale golden yellow: dorsal filaments same color as test, most numerous in median 

 and lateral areas, shorter than marginal filaments. 



Adult male. — 1 mm. long. 



Head: Antenna broken, only 2 segments remaining: basal bars diagonal; 12 

 setae between ventral ey^spots and antennae: 2 setae en dorsal surface. 



Thorax: Bar between wing bases nearly rectangular, three and one-half times 

 as long as wide: tibia about as long as tarsus. 



Abdomen: Five segments each with a pair of setae dorsally on lateral margin; 

 2 segments each with a pair of setae in ventral submedian area : lobes indicated. 

 each with 1 long and 3 short setae: penis sheath with 2 setae dorsally near base, 

 and 9 or 10 on each side of ventral opening. 



Male nymph.— Distinguishing characters similar to those of adult male. 



Third-stage male. — Resembling second stage, but nearly elliptical : dorsal surface 

 with 8-shaped pores more numerous than in second stage, arranged in a median 

 and a submarginal row and in a large group at anterior end : ventral surface' with 

 legs represented by 3 pairs of sclerotized areas, each with a straight, elongate 

 claw; apex of abdomen as in second stage, but slightly sclerotized on ventral 

 surface and with a short, irregular, sclerotized area anterior to each interapical 

 seta.
