Narrative:

As depicted in the company's diversion guide; the mexico critical terrain chart shows two reference fixes in the red cloud east of MMMX; which are no longer in the jeppesen A320 database: visos & VE257. Tried to enter both of these fixes into fix information for my situational awareness; but both returned not in database messages.suggestions: either this omission needs to be corrected by jeppesen or the critical terrain chart should be. I suggest adding apn VOR; [apan]; to the chart as a reference point; for added situational awareness [and] since this is part of a common SID for eastbound flights.
