Genus Trichoprosopon. 
A single species only so far has been received. As only one 
£ is present in the series I have not been able to dissect it, and 
so cannot see the structure of the genitalia. 
Mr. Urich has found the breeding-place of the species, so 
I hope soon to have an opportunity of describing the larvae.
