serrated. To this Dz Haan gave the generic name Sialis. That genus 
(Sialis De H. not Fawr.) is the same as Newromus Rampur, Neuropt. 
p. 441, which ought not to be separated from Chauliodes ; the species which 
T have indicated is Newr. ruficollis of Rampur. Another genus of 
Ramer, Dilar, unknown to me, with pectinate antenne in males, appears 
to be related, but has a greater affinity, as I conjecture from the descrip- 
tion and figure, with the Hemerobii. 
Hemerobius L., Fasr. (exclusive of species). Palps with last 
joint thicker, elongo-ovate. Prothorax small, shorter than the 
other segments of thorax. Wings ample, lanceolate, with costal 
border broad. Antenne: filiform or setaceous, mostly long. Tarsi 
with two claws, and intermediate pulvillus. 
a) Ocelli none. 
Sub-genera: Hemerobius Leacu, Drepanopteryx LEACH, Megalo- 
mus Ramp., Sisyra Burm., Chrysopa Leacu, Polystachotes Burm. 
Nymphes Leacu. (With antenne short, wings narrow, elongate ; 
habit of lion-ant.)

These broad-winged insects are provided with eyes shining with gold 
during life; the delicately latticed wings, as transparent as fine gauze, 
present the colours of the rainbow. The larva lives on plants, and 
resembles that of the lion-ant ; it feeds on leaf-lice, and is covered with a 
mealy substance, to which the cast-off skins of the leaf-lice adhere, so that 
the true form of the insect is often quite irrecognisable ; the small, oval, 
white eggs are seated on long thin pedicles upon twigs and leaves,

Osmylus LatR. 
Nemoptera LAtr., Nematoptera Burm. (species of Panorpa L.,
