[March, 
Chloroperla rivulorutn, Piet. — Generally distributed along the torrents. All 
the specimens collected appear to pertain to this species. 
Isopteryx torrentium, Piet. — Generally, but sparsely, distributed. The examples 
appear to belong here rather than to tripun data , Scop, (f lava, Piet.). 
Leuctra cylindrica, Piet. — Here and there ; a few examples. (It is scarcely 
probable that this is the cylindrica of Do Geer).- L. nigra, Piet. — One example 
from near the Statzer-See should probably be referred here. 
Tceniopteryx preetextata, Burm. ? — Yal Boseg. In the 6ame locality was 
found another species of the genus, which I cannot identify. 
Nemoura inconspicua , Piet. — Yal Koseg. 
Ephemerida:. 
I he few materials for this Family are in Mr. Eaton’s hands, and have not yet 
been fully determined. A large Heptagenia allied to lovgicauda, Steph., was very 
common at the Lake St. Moritz; another species of the same genus, allied to setni- 
colorata, Curt., occurred sparingly in other localities. A JSaelis was found at the 
Statzer-See. 
Odonata. 
Sympetrum stHolatnm, Clip., and S. scoticum, Donov. — Statzer-See. S. 
meridionale, Selys. Sparingly, usually along the road-sides far from water ; infested 
with the red Acari to the attacks of which this species seems so partieularlv liable. 
Cordulia metalhca, Y. d. L., C. alpestris, Selys, and C. arctica, Zett. — Statzer- 
See ( vide ante, p. 141). 
J£schna juncea, L., and jE. borealis, Zett.— Statzer-See (vide ante p. 141). 
Three or four other species of Odonata were seen at the Statzer-See, but could 
not be caught on account of the boggy nature of the ground ; amongst them was 
one of the Agrionidce (probably Enallagma cyathigerum, Clip.).

and the narrower pronotum, with the central longitudinal incision to 
posterior lobe narrower, but more sharply defined.
