BRUES: PARASITIC HYMENOPTERA. 103 



aciculations curving upwards to meet those of the vertex; cheeks 

 smooth. Antennae sHghtly longer than the body, flagellar joints 

 regularly decreasing in length; first one fourth longer than the second; 

 maxillary palpi nearly twice the length of the head. Prothorax with 

 the posterior margin strongly carinate. Thorax long and narrow; 

 mesonotum slightly longer than the propodeum and one half longer 

 than wide, its surface shagreened; parapsidal furrows deep; coalescing 

 at the middle to form a transversely areolate depression. Scutellum 

 with six small elongate pits at the base, its surface shagreened. Pro- 

 podeum transversely rugose-reticulate; with a median carina that 

 forks just before the middle to form a long petiolar area extending to 

 beyond the middle; spiracle small, circular; below it a complete 

 carina with an incomplete one below that. Pro- and mesopleura 

 irregularly striate and reticulate, the mesopleura with a shagreened 

 area at the middle below. Petiole of abdomen as long as the thorax 

 from posterior angle of propleura to tip of propodeum; slender, 

 scarcely bent, slightly widened at the spiracles and again after pos- 

 terior fourth, the apex twice as wide as at spiracles which are at basal 

 third ; its surface rugose medially, striate-reticulate on the sides, more 

 finely striate toward apex. Second segment microscopically trans- 

 versely aciculate, more distinctly so at base, as long as wide at apex 

 which is twice as wide as base; third to fifth minutely roughened with 

 a polished band at base; sixth polished; seventh longitudinally striate 

 on basal half. Legs comparatively slender; hind coxae finely sha- 

 greened above, their femora four times as long as thick. Front tibiae 

 finely spinulose on their anterior surface; middle ones minutely den- 

 ticulate; hind ones minutely tuberculate on hind edge. Submedian 

 cell slightly longer than the median, recurrent nervure received at base 

 of second cubital cell; subdiscoidal vein interstitial. 



This species is quite distinct in size and color from any others known 

 from the Indo-Malayan region.

9 . Length 2.7 mm.; ovipositor 1 mm. Honey-yellow, the thorax 

 somewhat darker than the head, abdomen, and legs; antennae black- 

 ened beyond middle; wings yellowish hyaline, with a faint cloud just 

 before and another just beyond the middle. Head as broad as thick, 

 scarcely widened behind the eyes, hind margin strongly carinate.
