ScENOPINIDiE. 
Scenopinus fenestralis. Perris (1. e. pp. 226-232, pi. 3, figs. 103 & 104) re- 
describes this species, figuring details of the larva and pupa, and noticing 
the apparently polyphagous habits of the former, which occurs in boleti 
attacked by other larvaj, in the hairs of furniture-stuffing, in swallows’ nests, 
and in dead worm-eaten wood. He reviews the various positions assigned 
to the family, and, from the almost perfect affinity between the earlier stages 
of S. fenestralis and Thereva conjinis^ has no hesitation in considering that it 
must be placed next the Therevidce.
