It's a common problem with the hive tyrant model.
The wings take up an arm slot on the model, but the model is still allowed to take 2 weapons in its rules. So you have to get creative.
The most common melee weapon taken on them is Monstrous Rending Claws. Since the wings sort of have claws, most people just count them as the weapon.
The feet also work as scything talons.
Boneswords are a bit trickier though, and you'll have to do some converting.
Some possible solutions I've seen people use are:
1. Mount the wings on the back of the model, instead of in the arm slots. Downside is it requires a fair bit of converting.
2. Mount weapons on the legs. Requires less converting, but looks kinda goofy.
3. Mount weapons on the wings.
4. Mount the devourers onto the hilts of the boneswords, so each arm is holding two weapons.

The 3rd edition hive tyrant came with rending claws, as part of the monstrous weapons sprue. The same sprue that used to come with warriors.
