THE materials for this group are very limited, consisting 
only of one species of Hemerobiide, four of Chrysopide, and 
one of Myrmeleontide. 
The only interesting feature consists in the existence of 
aberrant and probably strictly endemic forms of Chrysopide. 
Hemerobiide. 
Megalomus, sp. 
One ?, gummed on card (Blackburn, No. 25). 
I do not feel justified in naming and describing this insect in 
the absence of the other sex or of more materials, especially 
as there are no striking colour-characters. It is of the size 
and form of the European WM. hirtus, L., and also resembles 
it in colour to some extent; but the transverse markings on 
the anterior wings are less pronounced, and the apical spots 
on the posterior wings are wanting. It would not be safe to 
hazard an opinion as to the species being endemic or other- 
wise. Small Hemerobiide are liable to be carried on plants 
and shrubs when in the pupa state. 
Chrysopide. 
* ANOMALOCHRYSA, n. g. 
Tn form and facies similar to Chrysopa, but the wings have 
three or more series of gradate nervules (at any rate in the 
anterior pair), which are sometimes irregular; dividing ner- 
vule of the third cubital cellule angular beneath (thickened on 
its inner side), so that the cellule it forms is triangular ; sub- 
costa confluent with the costa before the apex of the wing. 
Antenne scarcely longer than the wings. 
Labrum truncate (this character a little doubtful owing to 
the condition). 
Tarsal claws dilated internally at the base. 
Abdomen of male ending in a dilated flattened superior 
plate, beneath which is an elongate triangular infertor appen- 
dage, the whole structure causing the apex to appear dilated. 
The characters emphasized in the foregoing description 
indicate structures aberrant for the family as a whole; but 
nevertheless the two species have the aspect of Chrysopa in 
all respects, and should be placed near Hypochrysa.
