434 LT.-COL. C. T. BINGHAM ON EXOTIC FOSSORIAL 



the apical two segments of the abdomen go, very variable species. 

 There is I think no doubt that the Burmese form (my ;S. Eliza- 

 hethcd) is only a race of this species, and I have also united 

 to it, though with some doubt, Taschenberg's Priocnemis gigas. 

 Taschenberg's description clearly shows his species has the 

 Hemipepsis or Mygnimia neuration, and, so far as I can make out 

 the sculpturing and colour agree very well with those of P. aureo- 

 sericeus. This species is a good example of the uselessness of 

 wing-neuration only as a generic character. I have examples of it, 

 all with bidentate claws, that have the typical Mygnimia, and 

 others that have the Priocnemis neuration.

This handsome species is common in Sikkim and on the higher 

 hills in Tenasserim. There seem to be two races — one (audax, 

 Smith), with the wings deep ferruginous yellow ; and a second 

 {fenestratus. Smith, funestus, Cam.), which has the wings dark 

 fuscous with a purple effulgence, though it is absolutely identical 

 in the form and sculpture and markings of the body. In fact 

 one specimen of the latter in the Museum collection is labelled 

 " Mygnimia audax, var. " in the late Mr. Smith's own handwriting.
