A fragment of a pale ferruginous wing, 6°8 mm. long,

See 
Asilus gurnetensis, sp. n. 
so far as visible, is exactly as in the living Philonicus 
albiceps, Mg., but the fossil species is somewhat larger. 
Philonicus is separated from Asilus by abdominal characters, 
so the fossil is referred to Asz/us in the broad sense. 
H. 1174.

Wing greyish hyaline, with dark veins; membrane 
Proctacanthus fractus, sp. 1. 
transversely corrugated. Length of fragment 5 mm., pro- 
bable length of wing 8 or 9 mm., thus very small for the 
genus.
