THE present " Synopsis of North American Neuroptera" has
been prepared by Dr. Hermann Hagen of Konigsberg (one of the
highest living authorities on this subject), at the special request
of the Smithsonian Institution, from materials in considerable
part supplied by the collections of the Institution, or furnished for
the purpose, by correspondents, at its request. It is hoped that
the publication of this work and its distribution throughout the
country will call attention to the insects of this order, and result
in the collection of fuller materials, to be used hereafter in the
preparation of a more perfect report.

For the purpose of making the present work serve the purpose
of a report on the Neuroptera of the New World, a list of the
names of the known South American species has been added.
Some of these have not yet been published, but descriptions of
them will shortly be presented to the world by Dr. Hagen in some
one of the German scientific journals.

The manuscript of this work was furnished by Dr. Hagen in
Latin, and it has been translated into English by Mr. P. R. Uhler
of Baltimore. To him, and to Baron R. Osteu Sacken, the Insti-
tution is under obligations for the careful examination and cor-
rection of the proof sheets.

PREFACE.

THE following Synopsis of the Neuroptera of North America
has been prepared in accordance with the desire of the Smithsonian
Institution, and contains all the known species found hitherto in
the United States, in the English and Russian colonies, Mexico,
Central America, and the West Indies. Many species described
originally as belonging to the last-named countries, may hereafter
be found in the southern parts of the United States.

The materials upon which the Synopsis has been based are the
following: —

1. Species furnished by the Smithsonian Institution, chiefly
Odonata, collected by Capt. J. Pope, U. S. A., on the Pecos River,
Western Texas (lat. 32°, long. 104°), by Dr. Berlandier and Lt.
Couch, U. S. A., at Matarnoras, and by Dr. Engelmann at St.
Louis.

2. The very numerous species collected by Baron Osten Sacken
in different parts of the United States, particularly at Washington,
at Trenton Falls, at Savannah and Dalton in Georgia, at Berkeley
Springs in Virginia, in Florida, in Cuba, on the St. Lawrence
River, and at Chicago.

3. A considerable number of Odonata, collected by Mr. Abbot
in Georgia, and furnished by the late Mr. Escher-Zollickofer of
Zurich.

4. A considerable number of Odonata, collected by the late Mr.
Guex at Bergen Hill in New Jersey, and communicated by Prof.
Schaum of Berlin.

5. A considerable number of Neuroptera from California, Ma-
ryland, Illinois, and North Red 'River (from Mr. Robert Kenni-
cott), furnished by Mr. P. R. Uhler of Baltimore.

6. Some species collected in Florida by Mr. Norton, and at
New York by Mr. Calverly.

VI PREFACE.

7. Other species collected in South Carolina by Mr. Zimmer-
mann, and furnished by the late Prof. Germar of Halle.

8. A considerable number of Neuroptera collected in Cuba and
furnished by Prof. Poey of Havana.

9. A considerable number of Neuroptera collected in Mexico
and supplied by Mr. de Saussure of Geneva.

10. My own collection, containing the types of Winthem, de-
scribed by Prof. Burmeister, and some species furnished by the
late Mr. Say.

11. Many species collected in the Russian colonies and in Cali-
fornia, communicated by Mr. Meuetries from the Imperial Museum
of St. Petersburg, and by Colonel Motschulsky.

12. The Neuroptera of North America of the Museum at Ber-
lin, furnished by Dr. Gerstaecker.

13. The Neuroptera of North America of the Museum at Yi-
enna, communicated by Mr. Kollar".

14. The Neuroptera of North America of the collection of the
Baron Selys Longchamps at Liege, with the types described by
Messrs. Ratnbur, Latreille, Palisot de Beauvois, contained in Ser-
ville's collection, and some supplied by Mr. Asa Fitch.

15. Some types, chiefly from Labrador, described by Mr. Bur-
meister, and contained in the collection of Mr. Sonirner at Altona.

16. The very great number of Neuroptera of the British Museum
in London, described by Mr. Fr. Walker, chiefly from Canada and
the polar regions, which I examined at London in 1857, with the
kind permission of Dr. J. E. Gray.

I have endeavored to cite the literature of the subject as com-
pletely as possible. Besides the printed works, I have taken ad-
vantage of written communications made by Mr. Haldeman and
Mr. Uhler on those species, which had been described by them. The
rare memoir of the late Mr. Say, "Godman's Western Quarterly
Reporter, Vol. II," could not be procured, except in a manuscript
copy kindly communicated by Baron Osten Sacken.

An exclamation mark (!) has been added to every species con-
tained in my own collection, or described by me from actual exa-
mination.

Where an (!) has been added to the name of the author, I have
seen the types which he described.

The foregoing statements show that the Synopsis has been prin-
cipally composed from species which I myself have examined, and

PREFACE. Til

which can be considered as undoubtedly fixed. There are, how-
ever, some, especially from the British Museum, which are not
entirely certain, the time I could spend at London not being suffi-
cient to determine all the species. The number, however, of spe-
cies mentioned in the Synopsis not examined by myself is but
small.

I have added a Catalogue of all the species of South American
Neuroptera hitherto described, and of the new species contained
in my collection. All the yet undescribed species have been added
to the present Catalogue, as their publication, which has already
partly been effected (Gomphidae), will soon be terminated.

There can be no doubt that the species named in the Synopsis
and in the Catalogue constitute only a fraction of the Neurop-
terous Fauna of America; may its incompleteness be soon shown
by a multitude of new discoveries.

DR. H. HAGEN.

KOENIGSBERG, 8th April, 1860.

Note. — The measurements given are in millimetres. A millimetre is
equal to .039 of the English inch, or about .04 (= z';). Multiplying,
then, any number of millimetres by four, and setting off two places of
decimals, will at once give us the inches and fractions.

Male imagines from Chicago seem to differ a little, the colors
are much paler, the apex of the penis is incurved, the basal half
of the antennce is black, the setae yellowish and the apex of the
articulations has a fuscous ring. P. bilineata from Washington
and P. limbata from New Orleans certainly are distinct species ;
the species from Chicago is colored very much like P. limbata, but

the penis is incurved. P. lilineata Say, from N. Red River (de-
termined by Mr. Uhler), is colored more like P. limbata from Chi-

BAETIS. 45

I have seen a specimen (9 Imago) from the Vienna Museum;
it may be the one described by Pictet (although the setse are longer,
14 millim.). As that female pertains, undoubtedly, to B. inter-
punctata, probably, therefore, B. flaveola is nothing but a female
B. interpunctata Say. On account of a slight fold in the anterior
margin of the wings the submarginal line is seen with difficulty.

I have seen a mutilated, smaller, female subimago from Ten-
nessee (with the wings expanding 18 millim.), which may be a dis-
tinct species.

Two specimens from Maryland agree with the description, ex-
cept in the color of the veins of the wings; the marginal ones are
black, or rather fuscous. Is the description good ? It should be
observed that the species of Baetis are very difficult to separate,
and perhaps some species heretofore described may be only syno-
nyms of others. A further acquaintance is necessary. A male and
female from Dalton, Georgia (Osten Sacken), and Washington (id.)

I have seen mutilated male and female imagines from Trenton
Falls ; are they the true B. canadensis Walker? A larger female,
expanding 30 millimetres, is pale yellow, wings hyaline, veins yel-
low ; the head and abdomen are wanting. In London I noted
nothing about Mr. Walker's species, except that it was "allied to

conclude that, not the first and second segments, but the second

Agrions.

The length of the second segment in Agrion antennata Say,
shows that it does not belong to the genus Agrion in its stricter

head fuscous, a transverse streak at the base of the antennae, and
another, occipital, sometimes absent, black ; antennae fuscous, base
and extreme apex yellowish ; prothorax varying in robustness,
anteriorly broadest, upon the middle transversely rugose, narrower
between the anterior and posterior tubercles, fuscous; with a
broad, transverse, yellow band behind the black anterior margin ;
or with a triangular yellow spot at base, before a black band; or
with the middle also yellow; mesothorax fuscous, or fuscous mar-
gined with yellow; abdomen fuscous or yellow, base above and
beneath black; anterior feet entirely rufo-fuscous, or with the
femora black, tibiae black inside, outside sometimes with a longi-
tudinal black stripe ; intermediate feet yellowish-red, with the
femora obscure, or yellowish, the femora black, with the apex
yellowish; tibiae behind the base, banded with fuscous ; tarsi some-
times (perhaps the other sex) with two broad lamelliform, yellow-
ish lobes, which are rounded at the apex ; (I have not seen this
to be the case but in two specimens ; types of M. brunnea Erich-
son, and of Uhler ;) posterior feet the same color as the intermediate
ones, with no lobes ; wings fuscous, the posterior half hyaline.

America.

I have seen many specimens ; I believe the species of Say and
Erichson not to be different ; Mr. Say describes both sexes, but
does not appear to have observed the remarkable lobes of the tarsi.

(The tarsal lobes are not characteristic of sex, but are found
present in both males and females ; the membranous character of
these lobes, and their great delicacy seems to render them liable to
disappear, by shrinking or accident; this probably accounts for
their absence in most of the specimens observed by Dr. Hagen ; in
a specimen which I examined the one middle tarsus had the lobes
beautifully apparent, while on the opposite tarsus only a vestige
was present ; on another tarsus only a white membrane was appa-
rent ; when well conditioned, the lobes are obvious upon both the
middle and posterior tarsi. The male has robust, cylindrical, hairy
anal appendages, superiorly, which will abundantly distinguish the
sex. Uhler.)

Hob. Philadelphia (Say, Uhler) ; Virginia (Uhler).

This species is very rare ; I have seen only one specimen ; the
words of Mr. Say, " On the submargin is an irregular, quadrate,
dark, fuscous spot, confluent with the carpus," do not agree with
my specimen.

(The species varies in sometimes wanting the quadrate brown
spot of the wings ; the tarsal lobes are apparent in this species, in
common with the preceding : I have seen a specimen in which the
apical spot of the wings is absent. The abdomen is generally yel-
lowish, with dorsal, triangular, black spots. Uhler.)

vitta ; the mouth anteriorly and the sides sanguineous ; antennas
fulvous, yellowish at base ; wings narrow, acuminate, fimbriated
with green ; all the veins green ; the divisory-veinlet of the third
cubital areole not reaching the first transverse veinlet of the first
radial sector.

Length to tip of wings 14 millim. Alar expanse 26 millim.

Hab. Washington (Osten Sacken); Mexico; California.

May not this be Ch. harrisii? the wings, however, are narrower.
The species has the divisory veinlet not reaching the first trans-
verse veinlet, or rather not clearly exceeding it; and it is very much
like Ch. vulgaris, of Europe ; but differs by the wings being nar-
rower, and more acuminate. Ch. acuta, of the Berlin Museum,
is perhaps this species (from Brazil, Surinam, Mexico) ; but it
differs in having fewer gradate veins.

Hab. Dinwiddie, Virginia (Drury).

I am inclined to believe that antennae have been affixed to this
species artificially, or that the wings have been glued to the body
of another kind of insect, by error. The green color is foreign to
the genera of Myrmeleons.

SUMMARY.

North America contains ...... 716 species.

South America contains ...... 507 "

Total . 1223 "

Deducting 53 species found in both North and South America, the whole con-
tinent of America contains 1170 species; of which 436 are new to science.

The actual number of "species not examined," 220 for North America and
128 for South America (total 348), is considerably less in reality; the species
entirely unknown to me are 83 for North America and 29 for South America
(total 112), mostly described by Say, Asa Fitch, and Pictet.

of Neuroptera, especially that of the neuration of the wings, the following
inexpensive little work may be recommended: Neuroptera austriaca, by

written in German, it will prove useful, on account of its plates, even to
those not familiar with that language.
