II. Abdomen black with a yellowish 

 band on the second segment. 

 Small species .. .. fiavocincta, ^xQ^xdo. 



^OT-E.—Chrysops flaviventris, Macquart, is not included owing 

 to the insufficient description. The only species of Chrvsops recor- 

 ded from New Guinea is Chrysops albicinctus , V. d. Wulp (Tijd. 

 Ent. xi, p. 103,1868), which Osten Sackcn in Ann. Mus. Civ. 

 Genova' xvi, p. '418 (1882), remarks may be the same as C. pellu- 

 cida, Fabr., but if V d. VVulp's figure of the wing is correct it is 

 quite distinct from any species of the Oriental Region, the w^hole 

 apex of the wing being brownish grey, bearing between it and the 

 transverse dark band a hyaline streak. 



Chrysops manilensis, 9 , Schiner.

Thorax and scutellum black, with slaty grey tomentum, the 

 former with two other indistinct contiguous pale grey stripes and 

 on each side a rusty yellow spot ; in front of the scutellum 

 appears a conspicuous band of golden yellow hairs ; similar hairs 

 appear on the rusty yellow spots (perhaps in well-preserved speci- 

 mens they are spread over the whole thorax) . Breast sides blackish , 

 a yellow callus beneath the base of wings. Abdomen black with 

 an oblique grey band at the bases of the first two segments, 

 the second and third segments with a similar coloured median line, 

 the following segments rusty yellow, the under side chiefly yellow on 

 the middle, blackish at the base and apex (" mitte " is given in 

 the original, probably an error). The abdomen is somewhat com- 

 pressed in both specimens, it may therefore be somewhat different 

 in design in well-preserved specimens. Head black, the face with 

 golden yellow puljescence on each side and in the middle, so that 

 the shining black tubercle takes the shape of a Latin V. Forehead 

 with yellowish grey tomentum, with a large convex shining black 

 callus above the antennae, impressed in the middle, and a shining 

 black spot at vertex. Antennae unusually long and very slender, 

 the joints almost equal in length, the two basal joints 5^el]owish, 

 the third brown. Palpi bright red-3'ellow. Legs red-yellow, the 

 femora at their extreme bases, and the posterior ones almost 

 wholly, brown. Tarsi blackish on the last joints. Fore tibiae a 

 little curved. Wings hyaline, the fore border and a median band 

 pale brown, the outer border of the latter concave, posteriorly 

 with a bluntly triangular hyaline incision. The lower margin of 

 the brown fore border is paler on the other side of the median 

 band. Two females from Manila. Length 3 lines. 



The species could only be compared with Chrysops bifasciatus, 

 Macq., but this species has a reddish yellow scutellum and the 

 markings of the under side of abdomen are different; there can be
