JL HIS genus contains but few species, the most 
remarkable of which is the Raphidia Ophiopsis of 
Linnaeus; a smallish fly, with rather large trans- 
parent wings, and a narrow thorax, stretching for- 
wards in a remarkable manner. It is found on 
trees, &c. in summer, but is rather a rare insect: 
the pupa, according to Linnaeus, resembles the 
complete insect, but is destitute of wings. 
Raphidia cornuta is a large species, equal in size 
to one of the larger Dragon-Flies, and is distin- 
guished by its very long, horn-like jaws, which 
extend far beyond the thorax, and are terminated
