A very handsome black medium-sized species with the bright 

 orange-red pubescence on the face and upper parts of the pleurae, with 

 the white-haired median and lateral spots on the abdominal segments, 

 with the black antennae and legs, with the dark rich brown wings, and 

 with the narrow nearly parallel-sided frontal stripe which contains a broad 

 and long black callus. 



This species is nearly allied to T. pratti, Ricaudo, in colouring 

 but it is at once distinguished by the black antennae and black palpi, and 

 by the more hyaline wings, quite clear at apex. Length 17mm. 



Face brownish yellow, paler at base, with a few black hairs, the 

 bright orange-red pubescence is here confined to the beard. Palpi 

 blackish with black pubescence more pointed than in T. pratti (stout, 

 almost the same width throughout). Antennae wholly black, the first 

 two joints with black pubescence, the third broad at base with a per- 

 ceptible tooth. Subcallus brown. Forehead ashy grey, narrow, the 

 same width throughout and about seven times as long as it is broad, 

 the frontal callus black, almost the same width throughout to within a 

 short distance of the vertex, very similar to that of T. pratti (long 

 and narrow, almost reaching the eyes with a long stout linear exten- 

 tion). Thorax and scutellum in this species bluish black, with ashy 

 grey tomentum, devoid of pubescence on dorsum, sides with long black 

 hairs; breast with similar orange-red pubescence to that of 1 . pratti 

 (with dense orange-red long pubescence). Abdomen black with median 

 white-haired spots, the segmentations white-haired at the sides only, 

 pubescence on the dorsum black ; under side black with white segmen- 

 tations. Legs black with black pubescence, some yellow hairs on the 

 fore coxae and tomentum on the others. Wings marked with dark rich 

 brown colouring, most intense on fore border and across middle of 

 wing, leaving the discal cell all however clear, and not extending beyond 

 the base of fork of third vein, so that the apex is wholly clear, pos- 

 terior border almost wholly clear, veins and stigma blackish, no appendix
