Yes, they are both E. camurius..
The broad white band, its position on the wings all match correctly. The 2nd specimen is very worn& the orange markings faded.
E.camurius is readily IDed because ir is the only species in the genus with a broad white band.
The band also makes a sharp triangle in space 1b.
The others have a narrow white band which do nt forms a sharp trangle in space 1b.
Huang made several collecting espeditions to the Tibetan side.
In the link below in colour plate IV fig 29 is E camurius. fig 27 E.longicaudatus, fig 28 E. bieti. http://www.zobodat.at/pdf/Neue-Entom..._0065-0151.pdf
Another species found in Tibet Assam, Manipur & surrounding areas E. tsangkei is now Teratozephyrus tsangkei.
This resembles E. camurius with a very thin white band.
