By the kindness of Professor YNGVE SJOSTEDT, Stockholm, I have had 
the pleasure to look over some Neuropterous insects, collected by Professor Dr. 
SKOTTSBERG's expedition. 
LONGINOS NAVAS, Zaragoza, has worked out material from the same source, 
and in this work, Vol. III, Nr. 16, he gives descriptions of four species, viz. 
Hemerobius Skottsbergi, Hemerobius Sjostedti, Chrysopa annularis and Chrysopa 
puerula. The descriptions of the two last named species are based on mate- 
rial in the larval stage, and I regret that these two descriptions have been 
published. The genus Crysopa contains several hundreds of species, but the 
development is only known of quite a few. The confusion in the genus as 
to the synonymy is at present overwhelming, and when descriptions of new 
species, only known in the larval stages and from out-of-the-way localities, 
increase the number of difficulties, it will be almost impossible to arrange such 
a genus in systematical respect. 
The material here at hand contains two species of the genus Chrysopa, 
one species of the rare and very interesting genus Gayomyza and three species 
of the genus Hemerobius. 
It is quite possible that one or both of the larvz, described by NAVAS 
as new species, may belong to the below named species, but at present it is 
impossible to settle that question. 
Chrysopa lanata Banks, Proc. Ent. Soc. Wash., XII, 154, Igto. 
One specimen from Easter Island, June (BACKSTROM leg.), was present. 
This species is a very wide-spread one in South America, and I possess 
a rather long series of specimens from different localities. It is easily known 
by its long slender and rather acute wings, the venation of which is strongly 
haired. J/, and J, in the forewing coalesce before the basal crossvein between 
Rs and M. Gradate veins rather numerous and placed in almost straight 
directions. Venation greenish, but the gradate veins and the crossveins between 
Cu, and Cz, in the forewing sometimes brownish. The genae reddish, a faint
