itself, continued as far as the base of the third segment ; sides of 

 abdomen brown, in the middle of the under side of abdomen an 

 abbre\'iated brown band. Abdomen of the female more brownish, 

 the first segment pale, the second paler still, almost whitish anteri- 

 orly, the spots as in the male, but not continued to the third 

 segment. All segmentations broadly paler, the first brown in the 

 middle. Wings perfectly hyaline, on the fore border from the base 

 to the apex, brown, below the cross-veins at the base is a some- 

 what oblique small inconspicuous band ; the larger band has a 

 deep incision on the inner border. Legs bright rusty yellow. In 

 Fabricius's, Westermann's and my own collection. Wiedemann, 

 Auss. zweifl. Ins., i, p. 196. 



x\ female specimen from Java in the collection of M. Serville 

 differs from Wiedemann's description by the shining blackness of 

 the face, with a grey spot on each side ; by the grey forehead 

 with two black calli, by the posterior border of thorax with 

 golden yellow hairs, by the black scutellum, by the fawn-coloured 

 legs with black coxae, and also the posterior femora. Macquart, 

 Dipt. exot. i (i), p. 163. 



According to Wiedemann the spot or rather the brown bifid 

 stripe ot the abdomen extends over the second and third segment 

 of the male, it does not extend beyond the second one in the 

 female. We have observed five females and two males in which 

 the stripe is equally present on the second and third segments. 

 From Java. M. Pa3-en's collection. Macquart, Dipt, exot, vSuppl.

Seven females from Buitenzorg, Java (1875) (Ferrari). The 

 identification is certain, although there are discrepancies, especi- 

 ally in the description of the face. Macquart notices the same 

 differences in Dipt. exot. i, p. 163. Osten Sacken, Ann. Mus. 

 Civ. Genova, xvi, p. 418. Roder, Ent. Nachricht, p. 234, records 

 the species from Ceylon. 



Six females from different places (in Sumatra). The above 

 specimens differ from the description and from most specimens 

 from Java by their darker colour, especially by the black 

 scutellum and the black- brown posterior femora. The posterior 

 tibiae in this species are broader in their whole length, and each 

 side with a short fine fringe of hairs. The face is very shining.

The figure of Haematopota liinata is evidently that of a 

 specimen of Chrysops dispar. No description is given. Chrysops 

 Hiatus, Wlk., from Bengal is only a rather pale-coloured specimen 

 with some lighter spaces in the wing-cells. Chrysops semicirculus. 

 a female in very bad condition, is, I now believe, only a poor 

 specimen of this species with the black markings of the abdomen 

 obsolete or almost so. Chrysops tcrminalis, Wlk., is a pale-coloured 

 specimen with the black bifid stripe not reaching beyond the 

 second .segment, as in Wiedemann's original description of 

 Chrysops dispar. Walker identified several specimens as Wiede- 

 mann's species and then described his two new species, placing
