430 Miss G. Ricardo on the Pangoniiia? 



Chrysops suavis, ^ ? , Locw. 



Two males and four females from Yesso, Japan (ISS?, 

 Prior), 1901. 13. 



The female only -was described by Locw. The male is 

 very similar ; the yellow colour on the first abdominal 

 segment is less marked and the black marks on the .second 

 segment coalesce, forming a squarish spot, with only a small 

 yellow triangular spot on the hind border. The dark 

 colouring of the wings is more extended, as usual in the 

 males. 



Chrysops japonicus, ^ ? , Wiedem. 



The two female types of C. aterrimus, Kirby, from Yoko- 

 hama, Japan, 77. 11 {Jonas), are specimens of the above 

 species, as suggested by Ost. Sack, in Wien. cut. Zeit. iii. 

 p. 316 (1884) ; there are also two male specimens and one 

 female from Yokohama, 1901. 13 (Prior). 



The species is mentioned by Locw in a note after his 

 description of C suavis, from which it is easily distinguished 

 by the entirely black face, a characteristic it shares Avith 

 C sepulchralis, Fabr., from which it differs in its larger size, 

 the sides of the thorax black-haired, and the wholly black 

 abdomen -with only black pubescence. The wing resembles 

 that of C. suavis, but in the female specimens the fifth poste- 

 rior cell is wholly clear, and nearly so in the male, in which 

 latter the basal colouring extends so far that it completely 

 coalesces with the band, only a very small white spot being 

 discernible at the base of the discal cell. 



Length 9 millim. 



Chrysops perspicillaris, (^ ? , Locw. 



One male from Italy, 54. 70 ; two males from P'l-ance ; 

 three females from France, 74. 86 {IVulker) ; one female from 

 Constantine, Algeria, c. x. 93 [Eaton] ; one female from 

 Upper Jordan Valley above Bakciret el lluleh (Waters of 

 Merom), 20. 7. 1901 [Cropjper), with a note "only amongst 

 papyrus.^' This species is said to be " not rare" near Turin. 



There are no specimens of C. inmctifer, Loew, in the 

 British Museum Collection, but 1 identified several males 

 and females from Syria as belonging to this species, whicli 

 were sent me for identification i)y Dr. Kertcsz. They are 

 distinguished from C. itaiicus, Meig., by their smaller size, 

 but are difficult to distinguish from C. persjncillaris, Locw, 

 by tlic characteristics lie gives.
