Beetle one is a *Trixagus *species (Throscidae). They turn up regularly in museum situations, though they are not regarded as a serious pest. Beetle two is probably a *Cryptophagus *species (Cryptophagidae), though there are other related families that can look very similar. They primarily feed on mould, so may be indicating a damp problem. Tony
