brown. Hind and intermediate tibiae cylindrical, hardly broadened in 
their middle part. The body and the legs provided with long brownish 
yellow hairs. Membrane of the wings hyaline with a faintly yellowish 
tinge. The venation a little darker than the membrane. All the longitu¬ 
dinal veins in the forewing with small brown dots, and all the cross veins, 
except that between the stem of M and the R brown and brownish shaded 
3 Rs. The third radial sector with 3 or 4 branches. The cross veins in the 
hindwings hardly darker than the longitudinal veins. The gradate cross 
veins in the forewing placed into two regular and oblique rows. The mar¬ 
gins of the wings and all the veins with long pale hairs. 
Forewing 7,5—9 mm; hindewing 6—7,5 mm. 
1 6 (type-specimen) Ust Vilui (B. P o p p i u s leg.); 4 c? 1 $ Irkutsk 
(A h n g e r leg.).One of the four males (the cotype) is placed in the au¬ 
thors collection. 1 name the species in honour of the well-known 
Finnish Entomologist Dr. B. P o p p i u s, who has collected the type 
specimen. 
At first sight this species has much likeness to Hemerobius humuli, 
but the quite different shape of the anal appendages in the male sex of 
the two species separates them easily. The new species differs also with 
regard to its cylindrical tibiae of the hind and the intermediate legs, with 
regard to the somewhat longer pilosity on the wings and to the pale cross¬ 
veins in the hindwings. In Hemerobius humuli only the apical joint 
of the antennae is darker than the remainder; in H. poppii several of 
the extreme joints are darker. 
Nosybus nobilis (Fig. 5) Navas, Broteria, p. 79, fig. 20, 1910. This 
species is described from specimens from Mozambique, placed in Museum 
Paris, and it seems to be a very rare species. In the collection of Museum 
Helsingfors is found a male specimen from Bulawayo(C.T. Erikson leg.) 
Face yellowish. Clypeus blackish brown. Palpi pale brown (their 
joints can not be counted). Vertex somewhat raised and with long pilo¬ 
sity, yellowish brown and with dark indistinctly bounded spots. No 
ocelli. Between the eyes two, rather large, somewhat globular eleva¬ 
tions, which are strongly haired. Antennae with about 42 joints; basal 
joint very long and stout, as long as 2:nd, 3:rd and 4:th joint united. An¬ 
tennae brown and with short black hairs. Prothorax brown and with 
yellowish lateral margins, almost as long as broad and with rounded front 
angles. Meso-and metathorax brown with more or less yellowish sutures. 
Abdomen pale brown. Legs pale, unmarked, and with very long whitish 
hairs. Fore-and intermediate tibiae as long as—or a Tittle longer than— 
femora; tarsi almost as long as the tibiae. Hind tibiae l 1 ^ times longer 
than femora; tarsi half as long as tibiae. Basal tarsal joint as long as 2:nd 
3:rd, 4:th and 5:th joint united; these joints of equal length. Claws very 
small. Spurs present. The body with long and whitish hairs. In the fore¬ 
wing M and R coalesce for a distance. Cu forks near base, i A and 2 A 
emit both small branches to the hind margin of the wing. 3 A short, 
stout and without branches. In the hindwing M forks ne ar to the base 
of the wing; Cu forks at the base, i A short and unforked. 2 A and 3 A 
not present. The following crossveins are present: one between R and Rs; 
one between Rs and the stem of M; one between R 4 and M 1 , one between 
M i and Cu 1 and one between Cu 1 and Cu 2 .
