Alulae: Diptera; a pair of membranous scales above the halteres, behind the root of the wing, one above or before the other; the anterior attached to the wing and moving with it, the posterior fastened to the thorax and stationary; see calyptra; squama; squamula; lobulus; axillary lobe; aileron; scale; tegulae: Coleoptera;
In addition to this large aperture, which is located on the lower part of the lobulus, there may be two other small perforations about 1.5 centimeters further up.
Laterally, it expands in either hemisphere into a considerable lobule, the superior semilunar lobule (lobulus semilunaris superior; postero-superior lobules), which occupies the posterior third of the upper surface of the hemisphere, and is bounded below by the horizontal sulcus.
The superior vermis is subdivided from before backward into the lingula, the lobulus centralis, the monticulus and the folium vermis, and each of these, with the exception of the lingula, is continuous with the corresponding parts of the hemispheresthe lobulus centralis with the alæ, the monticulus with the quadrangular lobules, and the folium vermis with the superior semilunar lobules.
Anteriorly, it overlaps the lobulus centralis, from which it is separated by the postcentral fissure; laterally, it is continuous with the quadrangular lobule in the hemispheres.
The Tuber Vermis (tuber valvulæ) and the Inferior Semilunar Lobule (lobulus semilunaris inferior; postero-superior lobule) collectively form the lobus tuberus (tuberæ lobe).
The lingula (lingula cerebelli) is a small tongue-shaped process, consisting of four or five folia; it lies in front of the lobulus centralis, and is concealed by it.
The lobulus centralis is a small square lobule, situated in the anterior cerebellar notch.
The inferior parietal lobule (lobulus parietalis inferior; subparietal district or lobule) lies below the horizontal portion of the intraparietal sulcus, and behind the lower part of the postcentral sulcus.
The superior parietal lobule (lobulus parietalis superior) is bounded in front by the upper part of the postcentral sulcus, but is usually connected with the posterior central gyrus above the end of the sulcus; behind it is the lateral part of the parietoöccipital fissure, around the end of which it is joined to the occipital lobe by a curved gyrus, the arcus parietoöccipitalis; below, it is separated from the inferior parietal lobule by the horizontal portion of the intraparietal sulcus.
