Figure 20,b; Plate 2, figure 9 



Female (holotype) : Head with vertex yellow, shining; face yellow, 

 labrum with brownish toward anterior margin; palpi yellow; basal 

 segment of antenna yellow, slightly brownish dorsolaterally toward 

 second segment, second to fourth (approximately) segments yellow- 

 ish brown, lighter than the following 20 (approximately) which are 

 dark brown, the next 20 lighter brown (antennae broken, of at least 

 45 segments); legs yellow; pronotum yellowish dorsally, almost as 

 long as wide, with irregular dark streaking, mesonotum and metano- 

 tum yellowish, darker laterally, pleura pale; adbomen yellowish. 



FoREwiNG (pi. 2, fig. 9): Length 4+ mm. (apex broken), width 

 1.4 mm.; membrane yellowish with one prominent brownish black 

 mark, a short, longitudinal, almost straight radiomedial streak, be- 

 ginning a little basad of the point of separation of Rs and MA and 

 extending basally between the two veins for about one-fourth of their 

 lengths before 1st r-m, very little faint light brown streaking between 

 the longitudinal medial veins distally from the outer gradates to 

 margin; pterostigma yellowish; longitudinal veins yellowish or pale 

 basally with short pieces of Sc and Rl just before coalescing brown, 

 distal forks of Rs, MA, and MP from about 1st r-m and 1st m, Cul 

 branches, and distal portions of anal veins darker in general, with 

 macrotrichial pits bordered with brown; outer gradates brown, bor- 

 dered, inner gradates in part brown, other cross-veins pale or yel- 

 lowish; Rs forking basad of level of point of coalescence of Sc and Rl ; 

 MA forking below above point; MPl+2 with first branch of fu-st fork 

 at angle, closer to main stem than second fork; Cul with four branches 

 to margin; three radial cross-veins, the fu-st just distad of end of radio- 

 medial streak to Rs, the second at point of forking of R2 + 3 from 

 R4 + 5, and the third below pterostigma at forking of R2 + 3; 2d m 

 between MA and MPl-f-2 directly below 1st r-m; 3d m directly below 

 2d r-m from MA to MPl+2; three inner gradates and six outer 

 gradates, mcluding sectoral cross-vein. 



HiNDWiNG (pi. 2, fig. 9) : Length approximately 3.5 mm., width 

 1.3 mm.; membrane unstreaked, almost hyaline; pterostigma pale 

 yellowish; veins pale except for brownish short sections of Rl just 

 before and beyond 1st r, both radial cross-veins, 2d and 3d A, which 

 are darker; Rs forking into R2 + 3 and R4-|-5 at a point slightly 

 basad of level of point of coalescence of Sc and Rl; Cul with two 

 branches to margin; six outer gradates. 



Female genitalia (fig. 20, b): Eighth tergite shorter dorsally; 

 ninth tergite with each lateroventral half elongate, anterior margin 

 more than one-half of and posterior margin about one-third of length,
