Female. Front and vertex about three times longer than wide; 

 ocelli in an acute-angled triangle, the posterior pair about one-fourth 

 their own diameter from the eye margin; antennal scrobes broad and 

 rather deep; eyes with an abundant but short, fine pubescence. 

 Antennal scape flattened but not expanded below, a little less than 

 four times as long as wide, widest on the apical half; pedical about as 

 long as the first three funicle joints combined; first four funicle joints 

 subequal in length, the last two about one-third longer, all increasing 

 slightly in width so that the sixth is about one-third wider again than 

 the first; club oval, rounded at apex, nearly twice as wide as the pre- 

 ceding joint and as long as the last five funicle joints combined. 

 Wings uniformly ciliated; oblique hairless streak narrow throughout 

 and interrupted below, the cut-off portion separated from the pos- 

 terior margin of disk. Length, 0.7 to 0.9 mm. 



Front, vortex and upper parts of thorax and abdomen brownish 

 orange yellow, the head brighter, the propodeum and center of abdo- 

 men more brownish; face, cheeks, occiput excepting a black spot on 

 each side above the neck, and underparts paler or more cadmium 

 yellow, the cheeks sometimes faintly tinted with brown next to the 

 occiput; concealed part of pronotum with two small blackish brown 

 spots, and the posterior margin of the collar whitish with a blackish 

 dot on each corner; tegulae concolorous with underparts with their 

 posterior margin brownish. Antennae concolorous with face, with a 

 large blackish spot on lower side of the apical half of scape appearing 

 on both outer and inner surface, basal half and two-thirds of pedicel 

 and club respectively and first four funicle joints black or blackish. 

 Legs concolorous with underparts with the tip of the last joint of 

 tarsi blackish. Wings hyaline, the veins pale yellowish. 



Male. Front and vortex about twice as long as wide; ocelli in 

 an acute-angled triangle, the posterior pair one-half their own diam- 

 eter from the eye margin. Antennae nearly as in the female, but the 

 scape is narrower or linear and the club smaller. Length, 0.5 mm. 



Front brownish orange yellow; most of vertex, the occiput and 

 upper part of thorax and abdomen brownish black sometimes varying 

 to brown, with the sides of mesoscutum and axillae, and lateral mar- 

 gins of the abdomen at the vibrissae narrowly brownish orange yellow; 

 face, cheeks and underparts as in the female except that the venter
