Leucorhinia glacialis Hagen, Proc. Bost. Soc. Nat. Hist., 18, p. 79, 
1875 ; Hagen, Trans. Am. Ent. Soc, 17, p. 234, 1890, 
Abd. male 24—26, female 23—24 ; h. w. male 25—28, female 25—27. 
Male. — Colors yellow and black. Labium black, a white spot at 
the sides, labrum creamy white, face milk white. Thorax yellowish 
brown, a broad mid-dorsal irreg'ular stripe of black, divided by the 
yellow carina, a humeral and lateral irregidar markings black. Legs 
black. Wings hyaline, nervure black, stigma short, fuscous to black, 
a yellow spot at each end in younger specimens, disappearing in fully 
developed imagoes. The costa at the apex yellow above, in front 
entirely yellow. Abdomen black, segment 2 and 3 to median trans- 
verse carina yellow, a yellow spot on the dorsum and the sides just 
beyond. Appendages black, the superiors cylindrical, thickened at the 
apex, with about seven small denticles below. Inferiors two-thirds as 
long, the apex with a shallow angular notch. Genital hamules bifid, 
the anterior branch slender, recurved, the posterior shorter, thicker, 
armed with bristles. 
Female. — Differs from the male by the entirely black labium and 
labrum, the yellow thorax, the yellow spots on segments 5 — 7 of the 
abdomen, and the yellow surrounding the fuscous area of the wings. 
Like the male the triangular anal spot is emarginate just below the 
median space. The abdomen has the venter pruinose, while on the 
male the blue extends over the dorsum also to about the eighth seg- 
ment. Vulvar lamina short, widely separated by a quadrangular notch. 
There seems to be some variety in regard to the vulvar scale, A female 
from Divide, Wis., has the laminse approximated, and the round lobes 
widely divergent. 
Life Zone : Boreal. Possibly also Transition. 
Wisconsin: Vilas Co., Divide, June 24-30, 1907. 
Time and Habitat — June to August along marshy shores of lakes. 
Leucorhinia proxima Hagen. 
Because of the remarkable similarity of the fauna of the White 
Mountains of New Hahpshire to that of Northern Wisconsin, as men-, 
tioned before in this paper, I feel justified in including this in the list 
of our Wisconsin species, as it is quite probable that it occurs ^vithin 
the borders of the state. The species is distinguished by the markings" 
stated in the table. The male has the anterior branch of the genital 
hamule bent strongly backward, the posterior is curved inwaM, both 
branches are without bristles. The vulvar lamina of the female con- 
sist of two very short, approximated tubercules. It is possible that the 
one female glacialis referred to in the description, of that species really 
belongs to proxima, but this I doubt, for the marlcings of the abdomen 
are decidedly diiferent.
