A MONOGRAPH or tHe Genus OSPRHYNCHOTUS, Srinoua. 
Family IconzEumonip#: Subfamily Cryprinm: Tribe Crypripes. 
By CraupEe Mortey, F.Z.S., &e. 
THis genus has been twice excellently described; in the 
first place, by Spinola (Magaz. de Zool. x1. 1841, p. 45), and 
later, in ignorance of any previous knowledge of it, by de 
Saussure (Distant’s ‘ Naturalist in the Transvaal,’ 1892, p. 229, 
under the name Distantella), though neither author assigned it 
a very definite classified position. That it is distinct from 
Acroricnus, Ratz. (= Linoceras, Tasch.), I am able to state from 
an examination of the typical species of both genera; Dalla 
Torre treated Ratzeburg’s genus as synonymous, but Schmiedek- 
necht in 1904 correctly tabulated the palearctic kinds under 
Acroricnus, which differs from Osprhynchotus in possessing two 
strong metanotal transcarine in place of only a subbasal one, 
in having the hind tibiz normal and not incrassate throughout, 
in its lack of central setz beneath the hind onychii, in its less 
‘compressed abdomen, posteriorly broader head with less excavate 
frons, in its centrally intercepted nervellus ; but most especially 
in having the mouth parts but slightly produced, whereas in 
true Osprhynchotus species they are rostriform, with both cheeks 
and clypeus no shorter than the face, surmounted by strongly 
exserted labrum and ligula, extending in all to three and a 
half millimetres below the scrobes in the typical species. 
‘*Osprynchotus’”’ peronatus, Cam. (Kntom. 1902, p. 182; placed in 
** Linnoceras”’ by its author at ‘ Spolia Zeylanica,’ 1905, p. 97) is 
an Acroricnus and very common in India, whence I have seen 
it from the Khasi Hills, Simla, Labatach, Sikkim, Shillong, and 
the Kangra Valley. I may be permitted to here bring forward 
the unknown female of Acroricnus syriacus, Mocs. (Magy. Akad. 
Term. Ertek. xii. P. 11, 1888, p. 12, male), which differs from 
the male in little but its terebra, and this is as long as the 
abdomen, excepting the petiole; it is a true member of that 
genus and was captured by Hscalera during 1900 at Kuh Sefid 
in south-west Persia. 
The large size and nigrescent or brunneous wings of 
Osprhynchotus render it one of the most conspicuous genera of 
the Ichneumonide. That considerable confusion has existed 
concerning the synonymy of the species is owing to the fact that 
Brullé, in my opinion, described an extremely rare one in 1846, 
and that Tosquinet mistook it for the commonest in 1896. 
W. A. Schulz’s remarks upon this genus (Zool. Annalen, 
1911, pp. 35-87), all the species of which he there wishes to 
regard as synonymous, appear to have been based upon 
insufficient material; he professes to have seen five examples of 
my last species, thirteen of my first, and an unrecorded number 
united under my second to fourth. Among these he failed to
