taken with it. Mocsary has bred it from a second species of 

 the Sphegid genus Sceliphron, S. destillatorium, IHig. 



3. ACRORICNUS SYRIACUS, MoCS. 



Osprhynchotus syriacus, Mocs. Magy. Akad. Term. Ertek, 1883, 

 p. 12, male ; Acroricnus syriacus, Mori. 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 ; cf. 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. 

 Gryptus 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. 

 Gryptus melanoleucus, Gr. Ichn. Europ. 1829, ii. p. 489 ; 

 Linoceras 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 Hahrocryptus porrectorius, with no flagellar band.
