HYPOCERA RECTANGXJLATA, new species. 

 Plate 35, fig. 9. 



Female. — Yellow; frons yellow, post-antennal bristles of moderate 

 size, frontal bristles large; front row situated close to the edge of 

 frons, wliich is convex; second row convex, ocelli distinct; ocellar 

 region darkened; antennae yellow; third joint of moderate size, nearly 

 round, arista yellow, pubescent, first and second joints swollen, 

 distinct; palpi yellow, moderately bristled. Thorax with four 

 indistinct brownish stripes, the lateral pair abbreviated in front 

 and broadest; one pair of dorso-central bristles,^ scutellum with 

 four bristles, the anterior pair hardly more than coarse hairs; abdo- 

 men with the hind margins of the segments bro^vnish-black; on 

 the third to sixth segments this is carried forward in denticulate pro- 

 jections, leaving only small, yellow, triangular patches laterally 

 and centrally; basal segment with a fringe of rather strong, closely 

 placed bristles on the hind lateral margin, second segment with a 

 lateral group of rather weaker bristles about the middle, legs entirely 

 yellow except for the dorsal surface of hind tibia, front tibia with 

 one spine at about the middle of the antero-dorsal surface, mid tibia 

 with two strong spines at about the basal third (one antero-dorsal 

 and one postero-dorsal) and one on about the apical third (antero- 

 dorsal), the portion of dorsal surface above the basal pair covered 

 with several transverse rows of closely placed short black bristles; 

 hind tibia without spines, but the whole dorsal surface clothed with 

 transverse rows of short black bristles ; wing with costa to beyond the 

 middle, costal vein distinctly, but not greatly, thickened, especially 

 at the junction of the first vein, first section one-half the length of 

 second, second thick vein bare, not so thick as costal vein, first 

 thin vein leaving thick vein at right angles, running straight into the 

 disk of the wing, then with a very abrupt turn continuing with a 

 gentle curve to the wing tip, second thin vein nearly straight and 

 running almost parallel with the first to near the wing tip, fourth thin 

 vein distinct, tip of wing infuscated; halteres yellow, darkened at 

 the tip. 



Length, 5 mm. 



Locality. — Tjibodas, Mount Gede, Java (altitude, 5,000 feet), 

 Bryant and Palmer, collectors. One specimen.

» There is in this specimen an extra bristle on the right side which I take to be abnormal.
