  We give a generalization of the classical Bombieri--Schneider--Lang criterion
in transcendence theory. We give a local notion of $LG$--germ, which is similar
to the notion of $E$-- function and Gevrey condition, and which generalize (and
replace) the condition on derivatives in the theorem quoted above. Let
$K\subset \Bbb C$ be a number field and $X$ a quasi--projective variety defined
over $K$. Let $\gamma\colon M\to X$ be an holomorphic map of finite order from
a parabolic Riemann surface to $X$ such that the Zariski closure of the image
of it is strictly bigger then one. Suppose that for every $p\in
X(K)\cap\gamma(M)$ the formal germ of $M$ near $P$ is an $LG$-- germ, then we
prove that $X(K)\cap\gamma(M)$ is a finite set. Then we define the notion of
conformally parabolic Kh\"aler varieties; this generalize the notion of
parabolic Riemann surface. We show that on these varieties we can define a
value distribution theory. The complementary of a divisor on a compact Kh\"aler
manifold is conformally parabolic; in particular every quasi projective variety
is. Suppose that $A$ is conformally parabolic variety of dimension $m$ over
$\Bbb C$ with Kh\"aler form $\omega$ and $\gamma\colon A\to X$ is an
holomorphic map of finite order such that the Zariski closure of the image is
strictly bigger then $m$. Suppose that for every $p\in X(K)\cap \gamma (A)$,
the image of $A$ is an $LG$--germ. then we prove that there exists a current
$T$ on $A$ of bidegree $(1,1)$ such that $\int_AT\wedge\omega^{m-1}$ explicitly
bounded and with Lelong number bigger or equal then one on each point in
$\gamma^{-1}(X(K))$. In particular if $A$ is affine $\gamma^{-1}(X(K))$ is not
Zariski dense.
