present. Halteres brown. Described from only one female from Pankio 

 (Formosa). 



I have no specimens, but saw this type in the British Museum 

 a few years ago. It is much more closely allied to T. sauteri, Ricardo, 

 than pratti, Ricardo, and I thought this species might be a local or 

 seasonal variety of the former. I am, however, obliged to take the 

 name of fuscicornis, as the specific one, until a number of this form is 

 collected. T. fuscieornis may be distinguished from sauteri, by its 

 broader frontal stripe and consequently broader frontal callus, by its 

 much more greyish thorax almost bare from pubescence (probably 

 denuded), and by its darker coloured wings ; these characters sometimes 

 appear in 7". sauteri.

Ann. Hist.-Nat. Mus. Nat. Hung., XI, p. 171, 1913 ; Suppl. Entom., 



Ill, p. 64, 1914. 



A blackish medium-sized species with a row of greyish white or 

 yellowish triangles and the similar-coloured bands on the black abdomen, 

 with the brown wings and the blackish legs, and with the very long 

 (from just above the frontal triangle to near the vertex) brownish black 

 frontal callus on the narrow nearly parallel-sided frontal stripe. 



Female. Head rather large, broader than the thorax, moderately 

 arched. Frontal stripe rather narrow, nearly parallel-sided but incon- 

 spicuously narrowed towards below, about seven times as long as its 

 narrowest part (I have not seen the species which has so narrow frontal 

 stripe as Miss. Ricardo described in Ann. Mus. Hung., XI, p. 171* 

 1913) or about five and a half times as long as its broadest part, cloth- 

 ed with yellowish brown tomentum which becomes yellowish grey 

 on the upper part, and covered with very short somewhat conspicuous 

 black pubescence which extends nearly throughout the whole Lngth of 

 the frontal stripe and becomes more conspicuous about the middle and
