PSYCHE.
NOTES AND r>ESCRIPTIOKS OF SOME NORTH AMERICAN LIBELLULINA.
BY HERMANX AUGTJST HAGEN, CAMBRIDGE, MASS, f . (:ELITHEMIS EPONINA nr~~y.
I first established Celithemis for this
species which is found everywhere in
the LJnited States, east of the Rocky
Mountains from Minnesota to Florida
and Texas; it also occurs in CLI~~. Lt
is rather variable in the spots of the
wings.

the exhibition of Canadian insects
(IS%) in London, England, a young
tnale said to be from Toronto, Ontario,
was labelled by myself C. azm (no
description), aftei- two males from En-
terprise, Fla. The female is unknown
to me. I believe this species is near to c. ejonina of which 1 have befo-e me
a large n~nnber from Enterprise. The
discovery of the female is still needed. 3. CELITHEMIS ELISA Hagen.
I have placed this species in my Syn-
opsis (1861, p. 182) in DijZax followed
by D. omafa and D. amazda, of which
I had then before me very insuficient
material. Wdsh directly referred D.
elisa to ceZithenzir and Kirby (I. c., p. 275) proposed the same for D. oy~ata
and D. mzanda. I have now before
me a Iasge ~naterial ranging from Can-
ada to Georgia. The species is very
remarkable in I~aving the tips of a11 the wings blackish as in C. fasciata; all
the other spots ase more OY less variable. 4. CELITHEMIS BALTEATA Hagen.
I have described the young fe~nde
from western Texas in my Synopsis
(I 861, p. I 40) anlong Tetyagmzeuria
with the remai-k, '&Does it belong to this genus?"
Later I sent this female and
the only male from Cuba {Poey) to
DeSelys and he answered '& a Libell&
but difficult a placer. " I have since
received both sexes and fi~lly colored
specin~ens from Key West, Fla. There
is no doubt but that the species belongs here and stands, though a little larger, between C. elisa and C. omata. By
a curio~~s, cllance this species is omitted from my Synopsis of 1875. A new
and full description is needed.

5. CELITHEMIS ORsAT'A Rz11nb.
Instead of two specimens mentioned
in my Synopsis (1861, p. 182) I have a
large numher from the eastern parts of
the tJnited States and I have been told
by Mr. Cdvert that it 11as been collected in Maine.
6. CEI~ITHEMIS AMANDA EIage11.
I have in my Synopsis ( i 86 I, p. I 83) described this species after the type ( 9) of Burineister from Georgia (his Libel-
Zzdo fmZcheZZa, a name used long before) as the next to D. onzata, llaving 6nly
two series of discoidal areolets. I 11ave now before me a larger inaterial, some
collected with D. omata and I think it
very probable that both forms may be
the same species and perhaps may be
fo~~nd in South An~eric:~ also.
The other species C. szlje&z given
in my Synopsis, (1861, p. 148) of which
I had then only a female is now referred to a separate genus, PseudoZeo~ Icirby.
There are believed to exist four species, of which I can not now give an opinion.
T believe tlmt it is very near to CeZi-
themis.

A pair caught in cop~~la at San Diego,

sepal-ate them as species. The size and
external appearance is similar to
D. madr'da. The wings are hyaline,
with the anterior margin to the mediana
ancl a sinall space at the base of the hind wings flavescent. The male is similar
to D. madida but tlie superior append-
ages have about a dozen sinall teeth on
a line beneath the apical half. The
female has on each side of the thorax
an oblique pale band, better defined and broader near the legs ; on each side
along the abdomen a black band is
indicated and is more developed at the
apex of the segments ; the dorsal median

segments, the vulvar lamina with the
lobes more pointed on the tip, and
bettes separated at the base.
If D. $mz'cos~a, as I believe, is
merely a variety of D. wadi&, four
smaller females fsom Victoria,

separated. The smallest is 31 mm. in
length ; alar expanse sonxn. ; pterostig- ma 2 min.
The wings are fumose, the
anterior margin flavescent in one,
another has the base to the nodus or
only beyond the triangle flavescent ;
the anterior pale band on the sides of
the thorax is plainly visible ; a large
black band on each side of the abdomen
is con2plete ; in one female the black

SYhTON17~MY OF THE HOMOPTERA DESCRIBED BY SAIF, HARRIS AND FITCH.
BY E. P. VAN DUZEE, BUFFALO, N. Y.
In the ho?mo$twa as in other branches
of OLIS favorite science a so1id fwnda-
tion was laid by. that illustrio~~s pioaeer of American entoinology, Thomas Say,
whose brief but concise clescriptions of many of our native insects ha\7e eli-
cited universal commendation from latei- st~~dents. Scarcely inferior to that of
Say is the work clone many yeass later
by Asa Fitch most of whose numerous
species may be readily recognized from
his short7 clear cliagnoses. Intermediate in point of time comes the work of
Tl~addeus William Harris to whom,
however, we owe the desci-iption of but
vesy few homoptero~~s insects. In the
psesent paper I propose to give the cor- .
rected nomenclat~~i-e of the homo$ie?-a
cicadbzae described by these honored
leaders of American entoinology so far
as it is known to myself or has been
made known by recent wsiters.
Many of these names have been in
common use for years, but a number
are to be fo~~nd only in rare or little
lcnown papers, and not a few are now
for the first time systematically placed. In a few cases where I still feel in do~~bt the reference is fdlowed by a question
point.
Of the 71 species described by Say
60 ai-e known to me ; a11 of those cle-
scribed by Harris7 6 in immber, and all
b~tt 15 of the 74 species describecl by
Fitch. Two of those. described by Say,
viz., 3'assus sanctas and Mem6racz's
suhalata, are, so far as I can learn, un- known to our later entoinologists. In
the cicadidae ancl ty$Alocy6idae I have
quoted all references from the studies
of Messss. Ulder and \Voodwosth
whose valuable sponymical notes on
these families may be found in Ent.
