6'. stabnlari^ seems to Ijeloug to those iusects, wliicli 

 easily move their headquarters and follow man everywhere; 

 usually we find it more in our houses than out of doors. 

 Osten Sacken reckons it under the North-American species 

 (see his Catalogue) ; Schiner (Dipt. Nov. Reise p. 304) men- 

 tions a specimen from Auckland , and according to Mac- 

 quart (Dipt. ex. Supp. 4. 256) the Paris Museum contains 

 specimens from Australia.

Aeneo-nigra ; capite, antennis, coxis anticis, genubus, 

 tarsorumque articulis duobus basalibus rufis; abdominis basi 

 flava diaphana ; alis fasciis quatuor fuscis ; prima basali ;

Metallic greenish black , shining. Head a little broader 

 than the thorax, brownish red as are also the antennae, 

 the proboscis and the palpi. Face short, enlarged towards 

 the underside, impressed in the middle, projecting at the 

 oral margin. Third joint of the antennae ovate; arista 

 long, thin and straight. Abdomen attenuated towards the 

 end ; the two first segments reddish-yellow and transpa- 

 rent. Legs piceous; the front coxae, the knees and the 

 two basal joints of the tarsi brownish red. Wings hyaline 

 with four darkbrown cross-bands ; the first close to the base, 

 the second issuing from the mediastinal cell (at about half the 

 length of the wing), striking along the medial cross- vein 

 and dilated towards the hind border of the wing, the 

 third band going obliquely over the discal cross-vein and 

 at the costa coalescing with the fourth band, which forms 

 a broad margin at the tip of the wing. 



A single specimen (which I take to be a cf on account 

 of the absence of the ovopositor) from the isle St. Martin , 

 presented by Mr. Rijgersma.
