very long; pvt. parallel, short; the bristles of the occipital row not long, but well 

 developed; genal bristle rather developed. 



Thoracic chaetotaxy complete, all the bristles black but not very strong ; 2 mpl. ; 

 pt. very long; scutellum light yellow, with four bristles, very broad at the base. 

 Abdomen narrow-elongate, bristly on the sides and at the end; ovipositor longer 

 than the last three abdominal segments. Legs rather long but not weak ; front 

 femora with a row of bristles beneath ; middle tibiae with a single spur ; bristle-row 

 of the hind tibiae very short. 



Wings proportionally long, with very small or indistinct costal bristle; first vein 

 not elongate, ending before the small cross- vein; second vein straight; third vein a 

 little curved, bristly over its whole length; small cross- vein after the middle of the 

 discal cell; posterior cross-vein short, perpendicular; anal cell drawn out into a long 

 point, longer than the second basal cell. Pattern of the wings like the type of hyaline 

 indentations and spots ; the hyaline indentations of the hind margin bearing a brown 

 triangular spot in the middle. 



Type : Phaeospila varipes, n. sp. 



This genus has a rather isolated position, the pattern of the wing being, how. 

 ever, not unlike that of Rioxa; in some respects the type species is not unlike the 

 European Platyparea discoidea.

 (PI. ix, fig. 30.) 



Very distinct by reason of the black body with yellow scutellum , by the legs 

 being variegated with black and by the black spots in the hyaline indentations of the 

 hind border of the wings. Length 6-7 mm., including the ovipositor. 



Head yellow, opaque, cinereous; frons darkened above the antennae and with 

 an ocellar black dot; antennae dark yellow, with short black hairs on the basa 

 joints; palpi and proboscis yellow, pale-haired, the palpi with some black bristles; 

 some short black bristles on the vibrissal edges ; hairs of the lower portion of the 

 occiput long and pale ; the third lower or. shorter than the other. 



Thorax black, shining, with pale pubescence ; the humeri and a small streak near 

 the external tips of the transverse suture dark yellow ; in the middle of the dorsum 

 are two longitudinal cinereous stripes ; metanotum black ; the anterior margin of the 

 hypopleura yellowish. Scutellum flat, broad, triangular, wholly yellow; bristles very 

 long, the apical parallel, the basal divergent. Squamulae white; haltères yellowish. 



Abdomen wholly black, rather shining, with pale pubescence; the bristles are 

 black; ovipositor black, the apical segments yellow; venter yellowish at the base. 

 Legs yellow, the coxae also; the apical half portion of the four posterior femora black 

 and the four posterior tibiae darkened at the base; femora with black hairs, row of 

 bristles on the front femora numbering 6 to 7. 



Wings blackish brown, with the following hyaline markings on the fore border : 

 the costal cell, an indentation below the base of the stigma, two approximate in- 

 dentations beyond the stigma, reaching the third vein ; on the hind border : three
