broad as its length at the hump, with the dorsal hump near the base 

 distinct but hardly pointed or hooked and < bearing some tiny black 

 bristles. 



Thorax brownish or greyish black, slightly shining, with very 

 faint greyish stripes before the suture which are best detected when 

 seen from behind, when they can be traced on the front part as two 

 rathe!v narrow stripes very wide apart with perhaps a middle stripe 

 between them being seen as a very narrow brownish line, but the 

 outer stripes are inclined to curve round in front so as to join the 

 broader grey side stripes which are distinct only before the praealar 

 calli ; praealar calli large and obvious though rather less ferrugineous ; 

 scutellum black, slightly shining, but slightly dusted with greyish on 

 the disc. Pubescence longer and more dense than in the female, but 

 much less composed of pale yellow hairs along the sidemargins, while 

 the disc there are more sparse very depressed thin greyish hairs ; 

 pubescence on the scutellum mainly black about the tip ; that on the 

 pleurae more dark sometimes almost black on most of the mesopleurae, 

 but with less conspicuous large tufts of yellowish or greyish hairs on 

 the pteropleurae and especially on the metapleurae, while pubescence 

 on the intermediate space yellowish. 



Wings, squamae, and halteres as in the female. 



Legs coloured as in the female, but pubescence longer and 

 more conspicuous and less pale on the hind femora and tibiae ; pu- 

 bescence on the front coxae mostly black but intermixed with numerous 

 long and yellowish grey hairs about the outer basal part ; the tiny 

 pubescence on the front tibiae mainly black throughout but on the 

 extreme base there is a few pale one intermixed, and on the middle 

 tibiae with long delicate not dense black pubescence all over, but 

 especially brneath and outside (though not so conspicuous) as in T. 

 tropicus; hind tibiae with short pale pubescence at just the base, and 

 with the dorsal ciliation much strong and coarse, black all the length 

 except at just the base, and with a finer less conspicuous partly pale
