except pulchella^ terminata and maculipennis n. sp.. in the first tarsal 
joint in all % 9 being as long as the second, instead of being some¬ 
what shorter, joints 1—4 being subequal, 4 a trifle the shortest. I met 
with a single 9 subimago of this species in 1862, and laid it aside as a 
“ nondescript.’’ In 1863 the species was abundant in June, near one of 
our saw-mills. No less than 5 of the S specimens described have the eyes 
fully rounded out, which is the surest sign of maturity both in Ephe- 
merina and Odonata, so that they cannot be considered as immature and 
colorless individuals of some other species. The colorless specimens 
of terminata described by me have their anterior tarsi as long as fully 
colored specimens. 
H. cruentata, n. sp.— Yellowish. Head with the eyes in the living insect 
pale bluish gray, a black line dividing the upper f from the lower ocelli 
fuscous; vertex sanguineous; seta dusky, whitish at tip. Upper surface of tho¬ 
rax sanguineous. Dorsum of abdomen sanguineous, the overlapping portion of 
the segments darker. Anal appendages pale, fuscous at tip; setse whitish, the 
incisures fuscous and towards the base alternately wude and narrow. All six 
legfi with the terminal ^ of the femora, and the basal ^ and terminal \ of the 
tibise. pale sanguineous, the sanguineous part of the femora darker at each ex¬ 
tremity, so as to present a narrow medial and terminal dark annulus; all the 
six tarsi with their claws and incisures dusky. Wings hyaline; veins and 
cross-veins moderate, the veins finer than the cross-veins, all fuscous except at 
the extreme base of the wing and the basal § of the costa, where the veins are 
respectively hyaline and yellowish ; the costal cross-veins all, including the 
oblique basal vein, of uniform coarseness, and the costa uniformly tinged with 
yellow. Half way to the tip of the front wing the 2nd costal vein is thick¬ 
ened and obfuscated for the length of half a millimetre, as infiavescens Walsh, 
and generally i\\ pulchella Walsh. 
The 9 is occasionally paler than %, and occasionally the venter is sanguine¬ 
ous. In two specimens there is a pair of subobsoiete pale dorsal vittse on each 
abdominal joint. The hyaline portion of the wing-veins extends a little fur¬ 
ther than in'^, particularly in the hind wings.—Length % —8 mill. 9 ^ 
mill. Exp. % 19 —20 mill. 9 22—23^ mill. Seta '^25—27 mill. 9 —20 mill. 
Ant. leg % mill. 9 (larger) 7^' mill. 
Two S ) three 9 . 
The % subimago, from which I have bred the imago, differs as usual. 
The setae are tinged with dusky, the fuscous incisures less obvious. In 1 
specimen the markings of the legs are much paler. In both, the wings, 
as well as all their veins and cross-veins, are dull opaque yellowish.— 
Length % 7 mill. Exp. S 20—21 mill. Seta % 12—14 mill. Two % ; 9 
unknown.—Closely allied to flavesceyis Walsh, but much jmaller, and 
the eyes are not bright greenish yellow as in that species. Differs also
