Palaearctic Acrididae new to the Indian Fauna
The present paper includes notes on several Acrididae of definite
Palaearctic affinities not previously reported from India, two of them
new to science but belonging to a purely Palaearctic genus.
It will be seen that the series comprises not only the Mediterranean
faunistic elements (Oedipoda, Calliptamus), and those of the so.uthern
Palaearctic steppes (Dociostaurus), but also much more northerly
ones such as Chorthip pus and even Gomphocerus sibiricus, which is
typical of the northernmost steppes and of the high mountains of
Europe.Peer reviewe
The genus Hilethera Uv. and its species (Orth. Acrid.)
3 láminas.The genus Hilethera has been founded by me in 1923 1 to include
a very peculiar new grasshopper from Palestine named H. hierichonica
Uy. To the same genus I have referred at the time an Arabian species
described by me the year before as Lerina aeolopoides Uy. and
at present I have before me two more new species, one from Turkestan,
another from Sudan which also belong to Hilethera. Since I am
inclined now to include in Hilethera also Lerina buxtoni U y. which
in 1923 I thought to fit better into Aiolopus, the genus Hilethera consists
of five well defined species, and I feel bound to present some
remarks on the characteres and relationship of the genus and its species,
as well as to give a key to species.Peer reviewe
Orthoptera Palaearctica Critica: VIII. A preliminary revision of the genus Aeropus Gistl. (Gomphocerus auct. partim) (Acrid.)
The type of the genus Gomphocerus Thnbg. has been fixed by Samouelle
in 1819 (Entom. Useful Conzpendium, p. 219) as rufus Thnbg.,
and the fixation was formally confirmed by Kirby in 1910 (Syn. Cat.
Orth., III, p. 154).Peer reviewe
Orthoptera collected by M. Sureya Bey in Turkey
My colleague M. Sureya Bey, of Angora, was very kind to collect
at my request some Orthoptera in various provinces of Turkey, and the
collection proved to be of great interest owing to an unexpectedly
high percentage of species new to science. Since the distribution of
Orthoptera in Asia Minor is still imperfectly known, I thought it useful
to publish not merely descriptions of new species, but a full list of
the collection.Peer reviewe
New or less known Acrididae from Central Asia
About three years ago I undertook, on the suggestion of my friend
V. I. Plotnikov, Director of the Central-Asian Station for Plant Protection
in Tashkent, a general survey of the Acrididae of Central Asia,
with a view of publishing a handbook for their identification and study.
As a basis of this work served collections sent to me by Mr. Plotnikov,
which proved to contain a number of undescribed species, or
such as have been only very inadequately described by previous authors.
A re-examination of Central-Asian specimens of other species,
recorded from the country before, showed that in a number of cases
they have been referred to known species incorrectly, being either
distinct specifically, or belonging to well distinct geographical races.
While the book on the Acrididae of Central Asia, containing keys,
descriptions and figures, is hoped to be published in Russian shortly,
I thought it imperative that all descriptions of new forms and notes of
systematic and synonymic value should be published separately and
in a more widely known language and the present paper is one of the
series written to this end.Peer reviewe
A revision of the group Mesopsis (Orthoptera, Acrididae)
The genus Mesopsis I. Bolivar is usually referred to the subfamily
Catantopinae, because of the presence of a prosternal tubercle.
This, however, is not an absolute character, since the tubercle is
absent in some members of Catantopinae, and present in some genera
of other subfamilies. On the other hand, the specialised elytral venation
in the male of Mesopsis and the presence of the stridulatory pegs
on the inner side of its hind femur are definite characters not of the
Catantopinae, but of the Acridinae. In fact, Mesopsis is clearly related
to Brachycrotaphus Krauss, which has been originally described
as a member of Catantopinae. but is an unquestionable Acridine. The
Acridine affinities of Mesopsis have been recently confirmed by Slifer
on anatomical grounds (Journ. Morph., vol. 65, 1939, pp. 444, 447).Peer reviewe
Orthoptera palaearctica critica: II. Genus Tropidopola St. (Acrid.)
The first species of Tropidopola vas described by Marschall in
1836 under the name Gryllus cylindricus from Sicily. Three years
later Serville (1839) described in his g-enus Opsomala an O. sicula from Sardinia, which also belongs to Tropidopola; another species
O. pisciformis, described by Serville in the same book fi-om Java and
Egypt and regarded by some later authors as synonymous with cylindrica,
has nothing to do with the genus since it is stated to have «disque
du prothorax... distinctement tricaréné»; it is possible that the
specimen fi-om Egypt which Serville mentions under pisciformis was
actually a Tropidopola, but the description was obviously based on
the specimen fi-om Java.Peer reviewe
Orthoptera Palaearctica critica: VI. Genus Bergiola Stschelk. (Tettig.)
Stschelkanovzeff described in 1907 (see bibliography at the end) a
new genus of Decticinae allied to Paradrymadusa Herrn., which he
called Bergiella, but this name proved to be preoccupied and in 1910
he renamed the genus Bergiola, publishing a German literal traslation
of the original description (it was mainly in Russian) and a photograph.Peer reviewe
