TABANUS MULTIPUNCTATUS. 73 



nigricantihus quatuor in singulis segmentis; ventre castaneo; 

 oculis nudis; antennariim articulis basalibus rufescentibus , 

 articulo tertio nigro ; palpis pallidis ; pedibus rujis , albido- 

 puberulis ; halteribus nigris; alis siMyalinis. — Q. Long. 

 21 mm. 



Face with whitish dust, ou the lower part with a dense 

 white pilosity ; palpi pale yellow ; front moderately broad , 

 light grey , between the corners of the eye with a round- 

 ed, shining, reddish-brown knob, which in the middle is 

 grooved and extends upwards in a narrow line, ending in 

 a blackish spot on the vertex. Eyes bare, dark coppery, 

 and without crossbands even after having been moistened. 

 The two basal joints of the antennae reddish ; the second 

 very short and embraced above by the first joint ; the third 

 one black, rather slender, its upper angle with a slightly 

 projecting tooth. — Thorax, scutellum and abdomen with 

 compact light-grey dust, on the thorax four ill-defined 

 brown longitudinal bands , the two central ones of which 

 are confluent posteriorly , whilst the two outermost are 

 beginning but behind the suture. Abdomen conical , but 

 little convex; on the front margin of the second and fol- 

 lowing segments a pair of blackish spots, placed close 

 together, and a pair of lateral ones, being a little larger; 

 undersurface of the abdomen of a chestnut color. — Legs 

 uniform brownish-red, in some directions grey, owing to 

 the whitish dust by which they are covered ; the tarsi 

 a little darker ; hind tibiae with a delicate , short , dense , 

 erect pile. Halteres fuscous. Wings with a greyish tinge; 

 veins dark-brown , bordered with pale brown , especially 



criptions. On account of the exceedingly great number of species belonging 

 to this genus (I think there are about 900), it is very diflicult to decide 

 with certainty whether a species is already described or not. It therefore 

 would be of no use to science, to add new species to them; I think how- 

 ever that an exception can be made with regard to the species which I 

 have described in this paper, because they are more recognizable than most of 

 the others. A general revision of the exotic species of Tab anus , in the same 

 way as Prof. Brauer h;is done it with the European ones, is very urgent.
