At the request of Baron Nordenskiöld I have examined 
the few Neuroptera (sensu Linn.) collected during his voyage 
in 1878—1879. They were received by me from Dr Chr. Auri- 
villius, of the Entomological Museum in Stockholm. All 
arer un falcomol and: are contamed in. 9 glass tubes. Only 5 
species are represented, and of these it is possible to determine 
only two with certainty; these two are Chilostigma preteritum 
Walker and Microsema scissaum Mc Lachlan (sp. nov.), both 
pertaining to the Trichoptera and found in abundance. 
Pseudo-Neuroptera. 
Fam. Ephemeride. 
Baätis, sp.? — Two small nymphs were submitted to the 
examination of Mr Eaton, who says they certainly pertain to 
the genus Baétis; specific identification is not possible. They 
are from Chabarowa, July 31", 1878. 
Fam. Odonata. 
Cordulia (Somatochlora) sp.? — One tube contains the 
posterior wing of a & Cordulia (Somatochlora) from Dickson's 
Haven, August 1878. I know not under what circumstances 
this wing was found, and it is not possible to identify the species 
to which it belonged. The high northern latitude would point 
to Cl archica Zett., but I do not think it belonged to that 
species, for in its general form, &c., it agrees better with C. 
metallica, Van d. Linden. All that can be said is that it is 
the wing of a & Cordulia (sub.-g. Somatochlora Selys). The 
discoidal triangle is empty, and there is an internal triangle.
