NOTES CONCERNING SOME NEUROPTERA IN HELSINGFORS MUSEUM. 
39 
As Mac Lachlan only gives a very short description of the spe¬ 
cies in Latin and a more complete one in the Russian language, I give 
here a re-description. 
Head yellowish; a median longitudinal brownish streak on the face; 
above the antennae a transversely placed brownish streak. Vertex raised 
and with three longitudinal short reddish brown streaks. Antennae short, 
dark brown, pale annulated. Thorax yellowish; prothorax with three 
longitudinal brown streaks; meso- and metathorax with an interrupted 
brownish streak at each side; between the lateral streaks some oblong 
and narrow brownish spots. Venter of abdomen brownish black with a 
narrow interrupted yellowish longitudinal streak. Dorsum yellowish 
with a blackish brown longitudinal median streak, which is narrowly 
interrupted at the joinings of the segments. Between the dorsal streak 
and the pleura several brownish black spots. Venter of thorax with several 
blackish brown irregularly placed spots. Legs pale. Upper side of femora 
with a brov/nish streak; tibiae with an incomplete brown band near base 
and a brown band at the tip; tarsal joints brownish at their tip. Basal 
tarsal joint as long as 2:nd and 3:rd together; 2:nd joint a little longer 
than 3:rd; 3:rd and 4:th equal; 5:th joint almost as long as 2:nd, 3:rd and 
4:th united. No spurs. Wings hyaline, almost whitish. Venation very 
pale, almost whitish, all the longitudinal veins pale. Where the crossveins 
are touching the longitudinal veins, as as rule small brownish spots are 
found. All the furcations along the apical margin with brownish spots. 
In the forewing the cross vein between R and Rs and nearest theptero- 
stigma ,the cross vein between Cu i p and Cu 2 and the cross veins in 
the series of gradate veins are all totally brownish. The pterostigma 
whitish with a brownish spot internally. The margin of both pairs of 
the wings is quite pale with exception of the very small'brown dots at 
the ends of the veins. All the markings on the wings have mostly the shape 
of dots or spots and not of streaks or bands. 
Forewing 18 mm; hindwing 16 mm. 
Euroleon (Myrmeleon) polyspilus G e r s t. (Fig. 3). This species 
was described from a male specimen from Amur. It seems to be a very 
rare species, and I do not know of any later record concerning it. In the 
collection was present a specimen from Ust Vilui, River Lena (B. Pop- 
p i u s leg.). It is a fine species, closely allied to Euroleon europctus Mac 
Lachlan, but easily separated from that species by its more strongly 
marked wings. 
Chrysopa fedtschenkoi Mac Lachlan. (Fig. 4). One specimen from 
Aschabad (A hnge r leg.). The specimen has lost its abdomen, it 
is rather immature and in a poor condition. It is the first time that I have 
seen this species, which is described in »Fedtschenko’s Voyage in Tur¬ 
kestan», pag. 22, t. 1, fig. 1, 1875. Head pale yellowish. A blackish spot 
between the antennae and the eyes, one below each eye, one at each side 
of the clypeus and a median brownish one just below the antennae. Ver¬ 
tex with two brownish irregular spots on the disc and with dark brown 
hind angles. Maxillary palpi pale, third joint with a broad blackish me¬ 
dian band, apical joint almost blackish. Antennae grache and pale; basal 
joint rather stout and with dark markings on its underside. Thorax pale 
and with a broad series of brownish spots on each side. Prothorax broa-
