Erythkopogon,* Glen. nov. 

 This genus is proposed for an undescribed Tasmanian 

 species. It is most nearly allied to Brac/iyrrhopala, but is at 

 once distinguished from that genns by the extremely long 

 antennae. The abdomen is an elongated club-shape, with a 

 long narrow stalk, a feature that, in conjunction with the 

 long antennse, gives it a close resemblance to one of the 

 hymenoptera. 



* Face long and flat, descending in a straight line from the 

 antennse to the moustache; the latter very small, and con- 

 fined to the oral margin. Antennae are placed extremely 

 high, and project horizontally forwards in a line with the 

 vertex ; they are four times the length of the head, the first 

 joint twice as long as the second, the third three times the 

 length of the first and second together, much broader than 

 either of them, and terminated by a rounded tip, that seenm 

 somewhat separated from the rest of the joint, although it 

 does not form a distinct style. Thorax has the shoulders 

 produced into prominent tubercles. Abdomen long and club- 

 shaped, much constricted towards the base, and more petio- 

 late than in Brachyrrhopala. Legs : Front tibiae with a small 

 and inconspicuous apical curved spine; femora practically 

 bare; tibi» with a few bristles. Wings large, with all the 

 posterior cells open.
