  Let $E$ be an elliptic curve defined over $\mathbb{Q}$ and, for a prime $p$
of good reduction for $E$ let $\tilde{E}_p$ denote the reduction of $E$ modulo
$p$. Inspired by an elliptic curve analogue of Artin's primitive root
conjecture posed by S. Lang and H. Trotter in 1977, J-P. Serre adapted methods
of C. Hooley to prove a GRH-conditional asymptotic formula for the number of
primes $p \leq x$ for which the group $\tilde{E}_p(\mathbb{F}_p)$ is cyclic.
More recently, Akbal and G\"{u}lo$\breve{\text{g}}$lu considered the question
of cyclicity of $\tilde{E}_p(\mathbb{F}_p)$ under the additional restriction
that $p$ lie in an arithmetic progression. In this note, we study the issue of
which arithmetic progressions $a \bmod n$ have the property that, for all but
finitely many primes $p \equiv a \bmod n$, the group
$\tilde{E}_p(\mathbb{F}_p)$ is not cyclic, answering a question of Akbal and
G\"{u}lo$\breve{\text{g}}$lu on this issue.
