 and Hong Kong. 



Walker's two types are similar to the other specimens of 

 C. dispar, F., in the British Museum Coll. C. ligatus, Wlk., 

 is only a rather pale-coloured specimen with some lighter 

 spaces in the Aving-cells. C. terminalis, Wlk., is a pale- 

 coloured specimen with the black bifid stripe not reaching 

 beyond the second segment, as in Wiedemann's original 

 description of C. dispar. The species seems rather variable, 

 the stripe extending sometimes only to the posterior border 

 of the second segment, but often to the third or even fourth 

 segment. Walker identified several specimens of C. dispar 

 correctly and then described his two new species, placing 

 them directly after C. dispar in his Catalogue ; but I can 

 see no differences sufficiently marked to justify them being 

 made distinct species. There is only one specimen among 

 the series which has a darker face, as mentioned by Macquart. 

 On one of the specimens from Ceylon Col. Yerbury has the 

 following note : — " Common and generally distributed. 

 Torments cattle. The scutelluni and the pilose stripe on the 

 pleuraj in life bright gamboge-yellow."
