taken with it. Mocsary has bred it from a second species of 
the Sphegid genus Sceliphron, S. destillatorium, Illig. 
3. ACRORICNUS syRiIacus, Mocs. 
Osprhynchotus syriacus, Mocs. Magy. Akad. Term. Ertek, 1883, 
p- 12, male; Acroricnus syriacus, Morl. Entom. 1914, 
p- 23, female. 
The unique female of this handsome Syrian species is in the 
British Museum. 
4, ACRORICNUS PERONATUS, Cam. 
Osprhynchotus peronatus, Cam. Entom. 1902, p. 182; ef. Spolia 
Zeylanica, 1905, p. 97. 
The author of this species, in 1905, pleads ignorance of 
Osprhynchotus when first bringing it forward, and then places 
it in Linoceras, where it is sufficiently correct, though the 
nervellus is intercepted somewhat below and not above its 
centre as is usually there the case; the metathorax is, however, 
bicarinate, though the apical transcarina is indistinct and 
obscured at the juncture of two colours. It is a common Indian 
species, and, besides the type, I have seen it from the Khasi 
Hills of Assam, Simla, in May, 1897, one which flew on to a 
table in Dehra Dun in the North West Provinces on June 22nd, 
1902, Sikkim at 1800 ft. in 1897, the Kangra Valley of the 
Punjaub at 4500 ft. in April, May and September, 1899, the 
Lushai Hills of Assam at 3600 ft. on July 14th and 17th, 1904, 
and Sukna in the Eastern Himalayas at 500 ft. on July 2nd, 
1908. 
5. ACRORICNUS AMBULATOR, Smith. 
Cryptus ambulator, Smith, Trans. Ent. Soc. 1874, p. 392, female. 
The British Museum type of this species belongs to the 
present genus and differs from the last species only in its much 
shorter and more convex metathorax, the apical colour of which 
is not centrally produced basally, in its centrally black face and 
in the black abdomen with apex of basal segment alone pale. 
It is from Hiogo in Japan and not, as given by Dalla Torre, 
from China. 
6. ACRORICNUS MELANOLEUCUS, Grav. 
Cryptus melanoleucus, Gr. Ichn. Hurop. 1829, ii. p. 489; 
Iinoceras melanoleucus, Tasch. 1865. 
Gravenhorst knew a couple of Italian females, which were 
revised by Taschenberg, but hardly anything appears to be 
otherwise known of this species in Nature; and I do not vouch 
for the correct determination of a male so named by Marshall, 
who took it in ‘‘ Corsica’’; this male is very like a small 
example of Habrocryptus porrectorius, with no flagellar band.
