40. Argyramoeha melania , n. sp. 



(Plate 5, fig. 8). 



Atra opaca'i facie ^ collare, pleuris et utrinque abdominis 

 segmentis 1 , 4 ei 5 niveo-pilosis ; alarum, dimidio hasali 

 nigro, colore nigra linea valde obliqua et in medio gradata 

 terminata. — cT (?)• Long. 13 mm. 



Dull black. Front narrowed behind, longitudinally groo- 

 ved , with a black pile ; face scarcely prominent , with a 

 white pile. Antennae black, short, pyriform , with a short 

 style, the end of which (when seen through a lens) shows 

 some minute hairs. Eyes angularly incised behind; the 

 broad and convex occiput black , with a whitish reflex. 

 Thorax with a black pile ; the collar , the posterior border 

 and the pleurae with a white pile ; on both sides before 

 the root of the wings some black bristles ; hind margin of 

 the scutellum and the first abdominal segment with a white 

 pile; in the middle of the hind margin of the second seg- 

 ment a short white hair-stripe ; the lateral pilosity of the 

 first, the fourth and the fifth segments a little longer, 

 accumulated and snow-white. — Legs black, the posterior 

 ones with small bristles. Halteres black, the tip of the 

 knob whitish. Wings hyaline with the basal half black 

 or brownish-black; this dark color does not quite reach 

 the hind margin , it covers the basal half of. the discal 

 cell and extends from there obliquely to the costa, about 

 as far as the end of the costal cell; the extremity of the 

 third basal cell (anal-cell) remains hyaline; the discal cell, 

 the two inferior basal cells and the fourth posterior cell 

 have a clearer disk ; the upper branch of the cubital vein 

 is angular at its base, with a recurrent vein. 



I received two specimens (which I believe to be males), 

 captured in Java by Mr. Piepers.
