78 ERAX RUFINUS. 



with VViedemaun's description; I raust however observe 

 that uot only of the black coloured hind-tarsi, but also 

 of the other tarsi (which are rufous with hairs of the 

 same colour and black bristles) , all the joints are very- 

 short and broad. The antennae are slender; the antennal 

 bristle is longer than the third joint. Wiedemann calls 

 the hairs of the palpi fox-red: in all the specimens I find 

 them black , which , according to ' Schiner , also occurs in 

 the typical specimens of the Vienna Museum. Macquart 

 sees a sexual difference in the colour of the hairs of the palpi 

 and describes them as yellow in cf , black in 9 ^ which 

 however is contrary to my experience. I see nothing of 

 the yellow hairstripe on the hind- tarsi, mentioned by 

 Wiedemann.

A male and two females from Brazil (Mus. Berol.). 



The characters given by Wiedemann are present in these 

 specimens. The antennae are pale reddish-yellow; the 

 first joint is the longest, cylindrical and beset with black 

 bristles, on the underside over the whole leugth, on the 

 upperside only at the end ; the second joint is short , and is 

 also provided with black bristles ; the third is not much 

 longer , lanceolate , with a black dorsal stripe and a black 

 endbristle, which is at least as long as the second and 

 third joint together. The face is not broad and becomes 

 narrower yet towards the vertex. I do not see the brow- 

 nish colour in the middle of the raetathorax, which Wie- 

 demann mentions. The bristles of the thorax and of the 

 legs are black. The mediastinal cell is blackish brown 

 and forms a dark stripe along the costa; the upperarra of 

 the cubital fork is at its base somewhat angulous, but in 

 none of my specimens it has a recurrent vein.
