eye, and 0.43 mm. long in the medial line. Ocellar plate raised. 

 Antennae and maxillary palpi testaceous yellow. Postpedicel 0.23 

 mm. long and 0.18 mm. wide, almost 1.3 times as long as wide; seta 

 shining black, bare, only the basal third testaceous yellow; approxi- 

 mately twice as long as the postpedicel. Labella yellowish brown. 

 Eye in profile 0.85 mm. high and 0.50 mm. wide, 1.7 times as high as 

 wide. Inferior part of cerebral plate very slightly raised, invisible 

 in profile. Genae below the eyes (0.07 mm.) and inferior part of the 

 postcranium in profile (0.11 mm.) very narrow. 



Cephalic bristles brownish yellow, except for black genal bristle; 

 considering the insertion points, the usual garniture present, but 

 nearly all bristles of the type specimen are broken except for lower 

 orbital, ocellar, and occipital bristles. Genal hairs brownish black. 



Thorax with scutellum 1.7 mm. long and 1.5 mm. wide, dark 

 testaceous yellow; mesonotum densely dusted with light brownish 

 yellow, golden iridescent dusting and pale yellow appressed hairs, 

 except for the shining hind margin. Anterior region of mesonotum 

 silky whitish dusted, this whitish dusted area ending posteriorly in 

 two wedge-shaped processes between the dorsocentral bristles, reach- 

 ing level of supra-alar bristles. Mesonotum with the following black 

 spots: the usual pair, each oval one between the prescutellar and upper 

 postalar bristles; one pair of long-oval black spots just before dorso- 

 central bristles, each one at upper termination of short branches of 

 transverse suture; one pair of small wide-oval spots, each situated 

 between presutural and anterior notopleural bristle, and a black dot 

 behind wing base. The special black markings on anterior region of 

 mesonotum make this species easily distinguishable from incompleta. 

 Pleurae shining, except for major part of mesopleuron (anepisternite) ; 

 on central part of sternopleuron (katepisternite) is a large trapezium- 

 shaped black spot, and ventral pleurotergite is almost wholly black 

 except the narrow brownish black upper margin. Scutellum shining, 

 with some appressed brownish yellow hairs. Postscutellum and 

 mediotergite shining golden brown; postscutellum yellowish dusted 

 with lateral parts black in color; these lateral black spots continue 

 in a pair of narrow black vittae which border lateral margins of the 

 shining mediotergite. 



Thoracic bristles brownish yellow; lower mesopleural bristle con- 

 siderably shorter and weaker than superior. Dorsocentrals situated 

 approximately in anterior third of distance between transverse suture 

 and supra-alar bristle, their spacing slightly wider than the prescu- 

 tellars, which stand approximately in posterior fourth of distance 

 between supra-alar and upper postalar bristle. Apical pair of scutellar 

 bristles slightly convergent and two-thirds as long as the divergent 

 basal pair.
