scutellum black; abdomen black, the segments ver}^ narrowly 

 bordered with yellowish white, a large band of the same colour at 

 base of second segment; coxae black, femora reddish, the posterior 

 ones black exteriorly, tibiae dilated, reddish, blackish exteriorly, 

 tarsi reddish with the apex blackish; squamae greyish, club of 

 halteres brown ; wings whitish, blackish exteriorly, from the base to 

 the apex included, with a large median cross-band of the same 

 colour. Philippine Islands. One specimen. Bigot, Mem. Soc. Zool. 

 France, v, p. 602. 



I have examined the type (female) from the Philippines lent 

 me by Mr. Verrall ; it is darker than the three other species with 

 black bands, and the yellow colour of the abdomen is not 

 diaphanous; it is nearly allied to C. fasciatus, Wied,, and 

 C. signifer, Wlk., but the abdomen is darker and the black bands 

 broader. 



I believe it to be the same as C. clavicnis, Thomson, from 

 Malacca; and if this proves to be correct, Bigot's name must 

 be sunk. 



The original description may be amended thus : — 



Face black, yellow at the sides, and with a central short 

 57-ellow stripe. Ahdonien with the first segment pale yellow and a 

 narrow black posterior border; the second is pale yellow on its 

 anterior border; the black band posteriorly is nearly equal in 

 width to the yellow colour; the third segment is almost wholly 

 black, with only a narrow yellow border anteriorly; the two black 

 bands join at the sides, but the second band is entirely straight 

 on its posterior border, thus differing from C. signifer, Wlk., 

 which is deeply indented in the centre; the fourth, fifth, sixth 

 and seventh segments are reddish yellow, with obscure black 

 square spots in the centre of the fourth and fifth. The wings are 

 clear, dark at the base and along the fore border to the apex, 

 and with the usual transverse band which extends to the posterior 

 border. Ricardo, Ann. Mag. Nat. Hist. (7), ix, p. ^J^. 



Black. Antennae, head and palpi yellow, legs brown, anterior 

 femora and tarsi testaceous, anterior tibiae club-shaped, fusiform; 

 wings hyaline, with the marginal border and an oblique median 

 band brown. Abdomen at apex brownish, at base honej^-yellow, 

 pellucid, with black median band. 

 $ . Length 10 mm. Malacca. 



Related to Chrysops rufitarsis, Macquart, Dipt. exot. vSuppL
