indicia

1. Identifying marks; indications.
2. Markings on bulk mailings used as a substitute for stamps or cancellations.

[Latin, pl. of indicium, sign, from index, indic-, indicator. See index.]

Signs; indications. Circumstances that point to the existence of a given fact as probable, but not certain. For example, indicia of partnership are any circumstances which would induce the belief that a given person was in reality, though not technically, a member of a given firm.

The term is much used in civil law in a sense nearly or entirely synonymous with circumstantial evidence. It denotes facts that give rise to inferences, rather than the inferences themselves.
