 smaller than the others), and fifth tergite with a pair of narrow vittalike 

 spots that do not attain the hind margin; fifth tergite 1.7 times

Figures 99,f,g: 102, t; Plate 24, figure 19 



A very distinct large species with special characters; similar to 

 tripunctata Hendel, but differs from all known species by having on 

 sides of the mesonotum only the pair of long-oval black spots, each 

 above the wing base (below the supra-alar bristle). 



Female: Length of body 6.0 mm.; wing 6.2 mm. long and 2.8 mm. 

 broad, 2.2 times as long as broad. 



Head 1.07 mm. long, 1.75 mm. wide, and 1.52 mm. high, testaceous 

 yellow with brown marldngs, symmetrical on both sides of inferior 

 part of postcranium. Frons at vertex 0.80 and at anterior margin 

 0.59 mm. broad, and in median line 0.66 mm, long; parafacial plates, 

 which widen considerably towards antennae, and a median vitta, 

 including the slightly raised ocellar plate, distinctly silky white 

 pruinose, much narrower than the bare testaceous-yellow vittalike 

 lateral parts of the frontal vitta. Antennae and the almost straight 

 subtriangular maxillary palpi testaceous yellow, labella yellowish 

 brown. Oral margin of mesofacial plate raised and considerably 

 prominent. Postpedicel long-oval, 0.32 mm. long and 0.22 mm. wide, 

 approximately 2.5 times as long as wide; setae bare, shining black, 

 except for the testaceous yellow basal sixth, approximately 2.5 times 

 as long as postpedicel. Inferior part of cerebral plate raised. Eyes 

 in profile 1.32 mm. high and 0.70 mm. wide (or long), nearly 1.9 times 

 as high as wide. Inferior part of postcranium in profile 0.27, genae 

 below eyes 0.13 mm. wide. 



Cephalic bristles brownish yellow and somewhat flattened; con- 

 sidering the insertion points, the usual garniture present but almost 

 aU the bristles of the type specimen are absent. No distinct genal 

 bristle; the short hairs on genae and on inferior part of postcranium 

 shining brownish black. 



Thorax with scutellum 3.0 mm. long and 2.0 mm. wide, testaceous 

 yellow in ground color; mesonotum covered with whitish pruinosity 

 and with appressed short yellowish hairs except for the bare and shin-
