H. 39. I had concluded that this must represent a new 
Cossid genus, but should have hesitated to publish it but 
for the kind advice of Mr. J. H. Durrant, who carefully 
examined it with me and gave me the benefit of his wide

knowledge of Lepidopterous venation. It is certainly 
Lepidopterous, although in Trichoptera only three veins 
usually arise from the areole (discoidal cell), and there is a 
general similarity to the type of venation represented by 
Limnephilus. The position of R; below the areole disagrees 
with Jefferis Turner’s hypothetical ancestor of the Cosside, 
but agrees with the Tineid Nemophora swammerdamella (di.)8 
OrTHOPTERA.

It is very interesting to find tegmina of male crickets 
quite as specialised as those of to-day, and apparently not 
differing from the modern genera. There is no advantage in 
trying to describe the complicated patterns in words, as the 
figures show what there is to be seen.
