The internal reproductive and alimentary structures of <i>Cuterebra tenebrosa</i> Coquillett were studied and compared to other calypterate flies. Well defined mouth parts are present. Paired lingual salivary glands extend horizontally almost to the abdomen: however, labial salivary glands were not found. The alimentary canal is complete in female flies, whereas males lack a crop. Females have three spherical spermathecae opening in to the upper portion of the genital chamber. Male reproductive structures are similar to those in other flies. Tracheal air sacs fill one-third to one-half of the abdomen.
