Observation .—This new genus resembles Lojohoscelomyia by 
the scales on the terminal segments of the 1 ' abdomen, but it is 
distinguished by absence 6f the scale tufts on the posterior 
femora which characterise the genus. On the other hand it 
resembles Nyssorhynchus, from which you can tell it by the scales 
on the thorax, which are all widely lanceolate on Nyssorhynchus , 
which all slope backwards on the mesonotum, by the scales of 
the head and the position of the scales of the abdomen.
