and appaiently becoming coalescent with the subcostal; 

 radial and cubital veins simple, but connected by a per- 

 pendicular cross-vein ; discal cell nearly triangular, with 

 three issuing veinlets, which are all complete ; anal vein 

 indistinct, but reaching the wing-margin ; first basal cell 

 slightly longer than the second, the second slightly longer 

 than the third. 



This genus may be recognised by the very distinct vena- 

 tion, also by the unusually long antennal style. Only one 

 species is at present known, 



Texontomyia gracilipes, vSp. nov. (Fig. 45.) 



Thorax light brown ; abdomen dark brown, with black 

 lateral bristles ; femora, tibiae, and tarsi light brown, the 

 tarsi apically darkened ; wings tinged with brown, and 

 with a light brown stigma. 



Length. Male, 5.5 mm. 



Hab. Mangalore and Northern Tasmania. 



Male. Face and front brown. Proboscis orange-brown, 

 thickened, and a little shorter than the height of head. 

 Eyes separated. Antennce black, of the form described 

 under the generic characters. Thorax light brown, un- 

 striped, devoid of pubescence, but with two rows of fairly 

 long black dorsocentral bristles, and long black lateral 

 bristles; scutellum with four black marginal bristles. 

 Abdomen dark brown, with a few black lateral hindmar- 

 ginal bristles. Legs very slender, bare, light brown, with 

 the tarsi apically darkened. AVings with the venation 

 described under the generic characters, tinged with brown, 

 and with a pale brown stigiiia. 



Of this species I have personally only come across a 

 single specimen, which occurred in the bush at Mangalore 

 on September 25, 1912, but Mr. Littler has kindly sent 

 me for examination several specimens from Northern Tas- 

 mania, so the species is probably more common in that 

 part of the island.

Proboscis long ; wings with the cubital vein unforked, 

 and not connected with the radial by any cross- vein. 



Head small and almost globular. Eyes either joined or 

 narrowly separated in the male, always separated in the 

 female. Antennae with the first two joints short, the third 

 conical and provided with a short style. Thorax rather 

 arched, with or without bristles. Abdomen slender, con- 

 sisting of eight segments; genitalia of male varying con-
