Key to Xylophagidae larvae
I can't confirm ID, but I can offer this key to larvae of Xylophagidae from Manual of Nearctic Diptera (volume 1, page 492):

1. Head capsule at least three times as long as broad. Thoracic segments with sclerotized plates dorsally. → 2
    Head capsule not more than twice as long as broad. Thoracic segments not sclerotized dorsally → Coenomyia

2. Sclerotization of prothorax in form of amoeba-shaped plates. → Rachicerus
    Sclerotized area of prothorax not divided into amoeba-shaped plates → Xylophaga
