shining black and smooth, convex, reaching the base of the an- 

 tennse, where it is rounded and not pointed, and allov^s only a 

 narrow^ streak of the yellow color on each side; antennae short, 

 dark yellow, the third joint almost rounded and brownish; arista 

 brown, microscopically pubescent. Thorax shining black, but 

 there are on the mesonotum before the suture 2 pale yellow paral- 

 lel streaks, which thus give it the appearance of having 3 united 

 black stripes ; pleurae shining brown, with a broad whitish stripe 

 in. the notopleural region, which reaches the middle of the meso- 

 pleura. Scutellum shining black, pale yellow toward the middle 

 above; 2 very strong apical bristles. Halteres pure white. 

 Abdomen shining black, pale yellow on the venter. Legs with 

 the coxae yellow; last tarsal joint blackish; hind femora dark- 

 ened on the last half. Wings as figured by Becker -^ but the 

 black fore border not surpassing the second vein at the base ; api- 

 cal brown spot surpassing the third vein and reaching the middle 

 between the end of the third and fourth veins.

Our specimens agree very well with the description in the color- 

 ing of the antennae, legs, and wings ; but the scutellum is entirely 

 black above, being also as coarsely punctate as the mesonotum, 

 and only below reddish or yellowish; the brown fore border 

 of the wings covers almost all of the third vein.

A female specimen is before me which I take to be the female 

 of Osten Sacken's male, while the female of Osten Sacken's 

 species belongs probably to some other species. This was not 

 known to Becker. From Osten Sacken's description of the male 

 there are the following differences: the basal joints of anten- 

 nas are black; the face and palpi are black; the first abdominal 

 segment and the middle of the second are pale yellow; all the 

 coxae are yellow; middle femora narrowly black near the base; 

 hind tibiae broadly black toward the middle ; hind femora wholly 

 yellow. 



95. Pseudeurina maculata Meij. 1904. 



A very distinct species previously known only from Java. 



96. NotipMla stemalis Thoms. 1869. 



An endemic species and a true NotipMla.
