bristles (ors) but weaker; anterior pair of ors longer than these and 

 subequal in length to the strongly divergent outer vertical and to the 

 ocellar bristles. 



Thorax 2 mm. long and 1.5 mm. wide, testaceous yellow in ground 

 color; mesonotum evenly covered with pale golden yellow dusting 

 and with short appressed pale yellow hairs, except for the bare and 

 shining ver^^ narrow hind margin ; three structural linear vittae in the 

 dusting of mesonotum, one median and two lateral in line of dorso- 

 central bristles which are visible only from behind. Only the usual 

 pair of black spots present on hind region of mesonotum, each between 

 the prescutellar and upper postalar bristles; behind (and beneath) 

 wing base a small black dot. The commonest three black spots are 

 present on the pleura: one below sternopleural bristle on katepister- 

 num, a large spot above hind coxa, and a double one on inferior region 

 of pleurotergites. Scutellum shining yellow, with some appressed 

 pale yellow hairs on sides. Postscutellum yellow, with a pair of 

 large triangular lateral black spots; medio tergite shining, intensive 

 reddish yellow. 



Thoracic bristles brownish yellow and long. Inferior mesopleural 

 bristle only slightly weaker than superior; dorsocentral pair placed in 

 anterior third of distance between transverse suture and supra-alar 

 bristles and slightly farther apart than prescutellar pair, which is 

 situated far before the level of upper postalar bristles. Apical 

 pair of scutellar bristles parallel and slightly shorter than basal pair. 



Coxae and legs testaceous yellow, except for the last two tarso- 

 meres of midlegs and distitarsus of hind legs, all of which are dark 

 brown. 



Wings with the general pattern of the genus ; costa blackened at tip 

 of humeral cross-vein and at tip of subcosta; a hyaline dot present in 

 apical band at apex of second longitudinal vein (R2+3)- Basal band 

 abbreviated, ending in an oval-shaped translucent brown cloud at tip 

 of anal cell. Subcostal cell (stigma) 2.3 times as long as basall}^ broad. 

 First costal section 0.68, second 1.70, thu-d 0.91, and fourth 0.54 mm. 

 long. Basal section of the fourth longitudinal vein 1.20, penultimate 

 0.48, and ultimate 1.48 mm. long. Inner cross-vein 0.33 mm. long, 

 distinctly shorter than the penultimate section of Mi and more 

 obliquely situated than the 0.63-mm.-long outer cross-vein. Anal 

 cell 1.02 mm. long, 2.5 times as long as the apical process (0.45 nmi. 

 long). 



Preabdomen without ovipositor 1.7 mm. long and 1.7 mm. wide, 

 shining testaceous yellow with appressed brownish black hairs; 

 only second to fourth tergites each with pair of rounded black spots, 

 the pair on third tergite wider spaced than posterior pair, the circular 

 black spots on second tergite very smaU. Fifth tergite (0.27 mm.) 

 distinctly (approximately 1.3 times) longer than sixth (0.20 mm.). 



Hal teres dark testaceous yellow with a brown knob.
