 nae, cylindrical ; labrum, notched. 



Genus Hemerobius (Linn.). Ocelli, none ; wings, entire ; 

 antennae, sub-moniliform ; labrum, entire.

Mr. Moseley, of Huddersfield^, arranges the Neuroptera as 

 follows : — 



Order, NEUROPTERA. 



Sub-Orders, Trichoptera (Caddis flies) ; Planipennia. 



Families. — PanorpidcB. (Scorpion flies). 

 Hemerobiid(B (Lace-wings). 

 Raphididce (Snake flies). 

 Sialidce (Alder flies). 



Sub-Order, Pseudo-Neuroptera. 



Families. — Libeliulidce (Dragon flies). 

 Ephemeridce (Day flies). 

 PerlidcB (Stone fly). 

 Psocidce (Book-mites). 



Moseley says : — " This order of arrangement is exactly the 

 reverse of that given by the British authority (McLachlan) on 

 these insects. The Trichoptera are so inseparably connected with 

 the Lepidoptera, and the Psocidce so much resemble the Ort/ioptera, 

 that under the present disposition of the orders 1 have been com- 

 pelled to adopt this course." 



Referring to the Heinerobiidce he says : — " The members of the 

 genus Chrysopa are of largish size, delicate green with light gauzy 

 wings, and bright brassy eyes. The species of the genus Hemero- 

 bius are small insects, blackish or huffish, and wings very 

 iridiscent." 



Dr. Hagen, whose series of Synopses of the Neuroptera are 

 standard, gives thirty-two species of the Hetnerobiidce. as British, 

 and classifies them as follows : —
