One male from uneertain locality. 



One female from Celebes. 



These two specimens have the facial tubercle shining 

 black and two distinct black bands on the posterior borders 

 of the second and third segments, not attaining the sides and 

 not joined. "Wiedemann gives the band of the wing as hardly 

 incised posteriorly. I have included it under those species 

 with no hyaline sinus, as the colouring only becomes fainter 

 on the posterior border and does not amount to a sinus.

There are no s})ecimens of this species in the British 

 ]\Iuseum Collection, but there were two females sent me by 

 Dr. Kertesz, of Budapest, from Borneo, for identification, 

 which I think belong to this species. There is also a very poor 

 specimen of what I believe to be C. peUucidus, F., in the 

 British Museum Collection. From the examination of 

 these, together with the descriptions, it seems probable that 

 peUucidus and translucens are both distinct species, the latter 

 not being a variety of the former, as suggested by Macquart. 

 His s) ecies is distinguished from peUucidus by the almost 

 wholly yellow first segment of the abdomen, there being only 

 a narrow black band on its posterior border, whereas the 

 Fabrician species is said to have the first segment wholly 

 black ; the second segment in translucens is yellow, with a 

 central black spot, and a yellow spot in the centre of this 

 last continued into the third segment ; of this there is no 

 mention in the description of C. peUucidus : the face in 

 C. translucens is brownish, with a yellow central stripe ; in 

 C. peUucidus it is apparently shining black.
