 triangular, disk moderately convex, lateral borders 

 nearly j)eri)endicular but willioul dislinct dursal 

 cariiiae, Plem'a (pi. 2o, (ig. S) less tomenlose and 

 pubescent; prothoi'ax with two or tlu'ee tiiick, whitisli, 

 short bristly setae; sternoj)leurou wilh black hairs 

 along \enlral margin. All l)rislles black: scapulars not 

 distitu'l ; huinersd slightly sliorler tli.'Ui anterior noto- 

 pleural or ])resulural; postei-ior Udlnplciual \ory sjiort, 

 1/2 as long as anterior; dorsocenlr^ds very slightly 

 divergent, on a line comiecting anterior supra-alars, 

 a little sliorler Ihan I he latter; prcscutellars very 

 slightly divergent, on a level witli inner j)osterior 

 supra-alars, distinctly sliorler tlian lallei-; scutellars 

 one ])air, jiarallel, situaled al niichlle ol' lateral borders 

 of scutelhim, conspicuously long; nu'sopleurals one or 

 sometimes two, in the latter case the lower one verj' 

 weak; pteropleural and sternopleural liristles distinct. 



Abdomen (])1. 21], fig. 9) shorter tlian hciid and thorax 

 together, as wide as thorax, shining ])lack, very slightly 

 whitish tomentose, rather sparsely cohered \\ith black 

 fine pubescence; genitalia black, not cons])icuous; 

 venter black, yellowisli pubescent. 



Wing (pi. 23, fig. 1) distinctly longer than body, 

 comparatively narrow, nearly three times as long as 

 wide, with apex rather narrowly rounded, black, with 

 seven hyaline indentations and two round spots as 

 follows: three costal indentations; the basal one in 

 second costal cell near base smallest, extending to rs, 

 a faint hyaline oblique line from here to extreme base 

 of Cu, its posterior end suddenly widened as a small 

 clear dot; the second just beyond ])terostigma, ex- 

 tending to R4+5 near r-m, largest and triangular; tlie 

 tliird very close to second indentation, smaller than 

 latter, extending to below Ro+a- Four posterior mar- 

 ginal indentations; two apical ones in 2M2, of which 

 the ])asal one is longer and reaches to just below an- 

 terior basal corner of cell, and remaining one at middle 

 of cell is long-triangular; two in Cu, of which the apical 

 is at middle of a])ex and not extendhig to cu, the basal 

 at tip of anal vein reaches cu. Two round spots; the 

 first in R5 before the middle, longer than the other; 

 the second in iMj close to r-m. Anal lobe more or less 

 paler, with base and apex quite hyaline. Costal spme 

 conspicuous; R, dii-ected abruptly toward costa apically ; 

 R2+3 distinctly undulate; R4f5 nearly siraiglit, extreme 

 basal portion and apex of rs with bristles; r-m straight, 

 perpendicular; m-cu moderately convex; pterostigma 

 nearh' one-third as long as second costal cell; anal cell 

 shorter than basal cell, ajjical nuirgin more or less 

 concave. Halteres liglit yellow, stalk reddish brown; 

 squamidae blackish, margin j-ellowish. 



Legs blackish brown, lil)iae and tarsi light yellowish, 

 black i)ubcscent. Foreleg (pi. 23, fig. 11) conspicuously 

 shorter tlian posterior paii's; femur with two or three 

 black bristly bans on ai)ical half of externodorsal 

 margin, two black long bristlj- haii's on apical half of 

 externoventral marghi; tibia slightly shorter than 

 femur; tarsi conspicuously longer than tibia, first seg- 

 ment slightly shorter than the four following segments 

 together, yellowish short bristles along ventral margins, 

 second to fourth segments with one pan- of black sphie- 

 like short bristles on ventral apex. Midleg (pi. 23, fig. 12) 

 as long as hindleg; femur as long as tibia, with very 

 sparse fine black bristly hairs on externoventral margin; 

 tibia with a nither short black apical spur, in addition 

 two short black spmelike bristles on external apex; 

 first tarsal segment distinctly longer than the four 

 following segments together, with two rows of light 

 yellow bristles on ventral surface, three ])airs of very 

 short black S])inelike bristles at ventral apex, second 

 to fourth segments with two rows of black short spine- 

 like bristles. Hindleg (]il. 23, fig. 13) somewhat thicker 

 tlian others; femur very slightly shorter than tibia, 

 pubescence as on midfenuu-; tibia slightly cui'xcd, 

 external apex with one distinct but rather fine black 

 bristle; tarsi as long as tibia, first segment as long as 

 the four following segments together, all segments 

 pubescent and bristled as in midtarsus, the last two 

 segments blackish. 



Length: Body 2.8-3.2 mm, w^mg 3.2-3.5 mm. 



Female. — Similar to the male. Sixth abdominal 

 tergum (pi. 23, fig. 10) slightly shorter than preceding; 

 basal segment of ovipositor shinhig black, very sparsely 

 black pubescent, nearlj^ as long as four preceduig ab- 

 dominal terga together, depressed, with distinct lateral 

 carinae; second segment shining blackish brown or 

 black.
