G. RiCARDO : The Oriental Tahanidac. 341 



somewhat deeper brownish, posterior border of the first segment 

 more broadly reddish, with a triangular grey-haired spot in the 

 middle, round which the reddish colour is conspicuous ; second and 

 third segment with a narrow triangular median, and grey-haired 

 side spots ; the others with only a median spot. Under side grey- 

 haired with a very broad blackish median stripe and narrow red- 

 dish segmentations. Markings of the wings hardly different from 

 those of //. pluvialis. Femora very pale reddish, white haired, 

 apex brown above ; hind tibiae with three brown bands ; the fore 

 tibiae brown, only whitish at the base. In Westermann's collec- 

 tion. Wied., Auss. zweifl. Ins., i, p. 218. 



Two males caught in May and July at Rawas and Silago 

 (Sumatra). The first joint of antennae distinctly thicker than 

 the following ones, and very shining black at the end. The fa- 

 cettes of the eyes with the exception of those of the lowermost 

 third are very large. Tibiae very broad and flat, on each side 

 with thick black-brown pubescence, which is longer on the poster- 

 ior pair. The markings on the wings are, according to Wiede- 

 mann, very distinct ; I will only add that the light band at the 

 apex is double and that a large square pale spot is present on the 

 posterior part which lies in the middlemost basal cell and traverses 

 the middle of the lowest basal cell. V. d. Wulp, Sumatra Exped. 

 Dipt., p. 19. 



The plate given by Wulp shows the apical band double, and 

 light markings below the stigma (which is not shown itself). 



Bigot in BuU. Soc. Zool. France, 1891, p. 74, where he gives 

 a table of Haematopota species, remarks that he does not include 

 H. asiatica (Rondani) in it, as the author attributes it to Wiede- 

 mann, but Bigot cannot find in what paper Wiedemann published 

 it, neither can I. Probably it is an error of Rondani's— he gives 

 the first two lines of the description of " H. javana," from Dipt, 

 exot., p. 100, and then adds a few further particulars. V. d. Wulp, 

 in his Cat. Dipt. S.Asia, says ''asiatica" is 2i lapsus calami. I 

 saw the type in the museum at Genoa ; it was in bad condition, but 

 the face appeared to have no spots, so that it is very prol)ablc that 

 it is not a specimen of H. javana at all. 



The following is the description of H. nigra, Wiedemann, given 

 as a synonym by Kertesz in his Cat. Dipt., 1906, on what autho- 

 rity I do not know, and without an examination of the type it is 

 impossible to decide : — 



Black, the posterior margin of thorax, scutellum and segmen- 

 tations of abdomen white; wings smoke coloured, with white spots. 

 Length 4 lines, from Java. 



Antennae ochraceous, hypostoma greyish white, white haired 

 and on each side between the antennae and eyes is a large l)lack 

 spot; forehead near antennae with a black spot. Thorax black 

 and black haired, sides brown, the posterior border and the scu- 

 tellum white haired. Abdomen a little ochraceous at base ; the 

 under side almost wholly reddish ochraceous. Wings with a median 

 dark band, convex behind, enclosing an obsolete white spot, with
