116 On some new Species of Newropterous Insects. 
A variety has both series of gradate veinlets in the anterior wings 
margined with blackish ; between them on the costa is a large sub- 
hyaline space without markings, and there is also a somewhat con- 
spicuous black spot near the base. 
I have no doubt that the two insects described above are varieties 
of one variable species. This and the next are allied to D. binocula, 
Newman, from Australia, which also seems to vary considerably. 
Hemerobius flavicornis, Walker, and H. hamatus, Walker, from 
America, which much resemble these in the shape of the wings, have 
no recurrent vein at the base of the costal area, and have been placed 
by Dr. Hagen in the genus Micromus (Neurop. N. America, p. 198). 
D. humilis. (Pl. VI. fig. 5.) 
D. ochracea, sparse pilosa; antennis pallide ochraceis; prothorace et 
mesothorace utrinque fuscescentibus ; pedibus pallide ochraceis, tarsis 
fuscescentibus: alis anticis ad marginem apicalem vix excisis, subhya- 
linis, griseo-ochraceo nebulosis, punctis raris fuscis, marginibus apicali- 
bus dorsalibusque fuscis albo punctatis, venis longitudinalibus fusco 
punctatis, venulis gradatis in serie interna novem, externa tredecim ; 
posticis hyalinis, pterostigmate ochraceo.

Hab. Australia (Moreton Bay) (Mr. Diggles); New Zealand (Otago) (Mr. 
Oxley), (Auckland) (Colonel Bolton). In my own Collection, and in 
that of the British Museum. 
Ochreous, slightly pilose; antennze pale ochreous; eyes lurid; pro- 
and meso-thorax somewhat fuscous at the sides; legs pale ochreous, 
tarsi fuscescent: anterior wings slightly excised at the apical margin, 
subhyaline clouded with greyish ochreous, and with a few scattered 
black dots most numerous along the costal margin; apical and inner 
margins narrowly fuscous, spotted with white ; longitudinal veins with 
fuscous points, 9 veinlets in the inner gradate series, some of which are 
fuscous, 13 in the outer; posterior wings hyaline, pterostigma ochreous. 
In the New Zealand examples the posterior wings have a fuscous 
dash at the anal angle, but they do not sufficiently differ from the 
Australian to warrant their separation specifically.
