52 THE DIPTERA-BRACHYCERA OF TASMANIA, 



Subfamily AntissinSB. 



7. Antissella, Gen. nov. 

 Britrht metallic flies. Antennae nearly twice the length of 

 liead ; eyes joinincr and hairy in the male, widely separated 

 and practically bare in the female ; scutellum unarmed or 

 with rudimentary spines ; wings with costal margin inflated 

 in the male.

Hend broader than long. AntennaB situated ab'-ut the 

 middle of *be head in profile, and nearly twice the length of 

 the head ; first and second joints <>f almost equal hngth, and 

 somewhat cup-shaped, third jidnt anuulated, rather longer 

 than the first two joints togetiier, ;ind provided with a blunt 

 style. Eyes joining and hairy in the male, widely separated, 

 and almost bare in the female. Thorax broadening behind; 

 scutelluu) unarmed or with rudimi nlary spines, whose posi- 

 tion is merely indicated bv a serration of the margin of the 

 scutellum. Al)don)en somewhat ovate, considerably broader 

 and a little longer than the thorax. Lf^-gs simple. Wings 

 with the mediastinal and subcostal veins apparently coalesceiit, 

 the radial very indistinct, the culiital with a long fork, the 

 lower branch being slighly longer than the stem, and more 

 than twice the length of the upper l»ranch ; discal cell with 

 four issuing veinlets, the first, second, and fourth reaching 

 the wing margin, the third only half wav to the wing ma gin. 



This genus is proposed tor a Sj.ecie that occurs hoth in 

 Victoria and Tasmania. It seenis to come near to Antissa, 

 created by Walker fo a West Australian sp- cies, but Antissa, 

 according to Walker's descripiion, has the antennae much 

 shorter than, instead of nearly twice the length of, the head.
