reaching as far as the scutellum, the median ones close together, 

 starting from the anterior margin, not reaching quite as far 

 posteriorly as the lateral ones ; pleurae and pectus ochreous or 

 ochreous-brown, the latter with yellow hairs ; a small black spot 

 before the intermediate coxae, and another much smaller almost 

 linear before the hind coxae; scutellum ochreous or brownish- 

 ochre, shining, covered with short black hairs, fringed at the 

 apex with short black bristles ; metanotum shining black. 

 Halteres pale ochre-yellow, more brownish towards the base of 

 the stem. Abdomen shorter than the thorax (in dried speci- 

 mens), as broad as it or a little narrower, brown, more or less 

 castaneous, tinged with ochreous, shining, clothed with short 

 yellow hairs. Legs brownish-yellow, with a dense short yellow

 brown towards the base of the wing ; delicate opaline reflections. 

 Middle transvei'se vein erect ; posterior transverse vein slightly 

 bent, separated from the middle transverse vein a distance equal 

 to scarcely twice its length, and at a point rather nearer to the 

 latter than to the tip of the fifth longitudinal vein (pi. x.,

Larva, long 4^ ; broad If lines. Puparium, long 4; broad 1|-
