has a single row of pale cilia ; the scutellum bears a single long 

 bristle at each side, and the prosternum a slighter one. The wings 

 are somewhat narrowed towards the base, the anal angle being 

 rounded away, the anal and subanal veins obsolete, the discal 

 transverse vein distant by more than its own length from the hind 

 margin, the subapical vein straight and gradually diverging from 

 the cubital to the end. The abdomen is compressed, merely 

 pubescent, not ciliated at the incisures; of six segments in the 

 female, besides the vagina, and of only as many in the male, 

 including the short hypopygium, which is furnished with a pair 

 of inflected foliaceous, but narrow, pubescent appendages. The 

 posterior femora have a spine in front near the tip, the posterior 

 tibia3 not many spines, and the fore pair are nearly unarmed ; the 

 anterior metatarsi are long, the hind one shorter than the following 

 joint, unarmed. The species are very minute, and the colours 

 not metallic.
