Abstract: The following theorem is proved.

Theorem. Let $ X$ be a homogeneous continuum such that $ {H^1}(X) \ne 0$. If $ \mathcal{G}$ is the collection of maximal terminal proper subcontinua of $ X$, then

(1) The collection $ \mathcal{G}$ is a monotone, continuous, terminal decomposition of $ X$,

(2) The nondegenerate elements of $ \mathcal{G}$ are mutually homeomorphic, indecomposable, cell-like, terminal, homogeneous continua of the same dimension as $ X$,

(3) The quotient space is a homogeneous continuum, and

(4) The quotient space does not contain any proper, nondegenerate, terminal subcontinuum.

This theorem is related to the Jones' Aposyndetic Decomposition Theorem. The proof involves the hyperbolic plane and a subset of the circle at $ \infty $, called the set of ends of a component of the universal cover of $ X$.
