Scamboneura 



nov. gen. 



General appearance of Pachyrrhina, from which however it 

 diflFers in the venation. Rostrum short, with a distinct nasus; palpi 

 long, with a long, whiplash-shaped terminal Joint; antennae 13-jointed, 

 once and a half longer than head and thorax together; first Joint of 

 the flagellum about twice as long as the first Joint of the scapus, cy- 

 lindrical; the following joints gradually decrease in length and have a 

 very slight swelling at the base, which bears a couple of hairs; the 

 whole flagellum is microscopically pubescent; the 13"^ Joint is much 

 smaller than the preceding one. Legs very long and slender, tibiae 

 with minute spurs, which are more distinct on the last pair. Abdomen 

 moderately club-shaped at the end ; the forceps is provided with a pair 

 of small, triangulär foliaceous appendages, which resemble those of 

 Pachyrrhina. Wings: the venation resembles that of Dolichopeza 

 sylvicola, but the praefurca (very short in that species) is entirely 

 obliterated here, and the great crossvein is posterior to the proximal 

 end of the fourth posterior cell; the auxiliary vein is distinct and ends 

 just before the stigma ; the anterior brauch of the second vein is obsolete, 

 and perhaps represented by a slight thickening at the distal end of the 

 Stigma; the discal cell is wanting; the veins, on the distal half of the 

 wing, are finely pubescent.

Scamboneura dotata. 



The venation, the structure of the antennae and the slenderness 

 of the legs, sufficiently prove the relationship of this genus to Do- 

 lichopeza. 



As far as I remember, the Limnobia vittifrons Wk., J. Pr. L. 

 Soc. V, 144 (Amboina), which I saw in the British Museum, is a 

 Scamboneura, but I cannot recognise my S. dotata in Mr, Walker's 

 description. 



Scamboneura dotata n. sp, $ 



Rostrum and palpi yellow; front reddish-yellow with a brown line 

 in the middle; vertes grayish; scapus of the antennae yellow, flagelliun 

 brown, except the distal half of each Joint which is yellow; the extent 

 of this yellow color gradually diminishes on each successive Joint, so
