which hardly extend beyond the apex of the head for more 
than a quarter of their length, surface deeply punctured, 
without erect pubescence. Species dimorphic ; in the deve- 
loped form with the membrane as long as the apex of the 
abdomen, in the undeveloped with the membrane very 
short; legs simple, anterior femora unarmed. ‘There is 
only one European species of this genus.
