with some small oblong yellovvish brown markings, Legs with I)rown 

 femora, which aro whitehaired; tibiae (mostly black) and the black 

 tarsi blackish haired; spurs and claws black. Wings with streng- 

 smoky-brown tinge (probably due to the maturity); nervures dark 

 brown to blackish. Pterostigma very short, brownish Idack, with 3 

 or 4 Gross veins. 



Length of body 45 mm; fore wing 3U min; bind wing 25 mm; 

 antennae 23 mm. 



One specimon, S from Kankau (Koshun), V. 1912. 



This species differs from the Asiatic, Malayan and Australian 

 species of the genus by its long and slender abdomen, and it seems 

 to be closely allied to the African species, Siiph. abdominalis Mac Lachl. 



Helicomitus dicax Walk. 



Walker, Cat. Neur. Ins. Brit. xMus. 1853, pag. 423. 



Of this wide-spread species is present a large series of specimens; 

 all collected at Anping, Juno, July and August 1912. Mr. H. Sauter 

 remarks following about the species: „Anping <S. VII. 1912. Lampe. 

 Bisher nur bei einem alten chinesischen Port in der Nähe von Anping 

 gefangen. Vielleicht Larven oder Puppen mit Sand von dort ein- 

 geführt". 



Ächeron trux Walk. 



Walker, Cat. Ncur. Ins. Brit. Mus., 1853, pag. 432. 



47 specimens from various localities: Kosempo, Kankau, Taihan- 

 roku, Taihorin, Hoozan, Anping and Sukutsu; May to October. 



Osmylidae. 



Osmylus tuberculatus Walk. 



Walker, Cat. Neur. Ins. Brit. Mus. 1853, pag. 235. 



8 66 from Alikang. VIII. 1910; 9 66, 1 $ from Kosempo 7. VII. 

 1911: 17 66 Sokutsu, V. 1912; 1 6 Kankau, IV. 1912; 1 6 Anping 

 7. VII. 



With sllght hesitation I refer the specimens to the species of 

 Walker, as they agree very well with the short -description. The 

 species belongs to that group, in which the male has a tubercle on 

 the bind border of the fore wing. The species described by Navas 

 (Revue Russe d'Entom., XI, 1911, pag. 113, fig. 3) under the name 

 Lysmus nikkoensis is closely allied to this species and probably the 

 same. The greater part of specimens before me have simple cross 

 veins in the costal area, but some have a number of the cross veins 

 forked as in the European species, Osmylus maculatus, 'Ar\6. ihevQioYc
