It may be necessary to remove some of the hairs from the base of the wing. Use a small sable brush for this. Study the unbleached wings of the female, and note the absence of a frenulum hook.

The determination of the homologies of the wing-veins of Hymenoptera is very difficult ; as even in the most general-. FIG. 6.— The veins of a typical hymenopterous wing. ized of the living members of the order, the venation of the wings departs widely from the primitive type. For this reason no student should begin his study of the venation of wings with hymenopterous insects. In the following dis- cussion it will be assumed that the student has carefully per- formed the work on the wings of Diptera outlined in the preceding pages ; and the first step for him to take at this point in his studies is to take his drawings of dipterous wings and review that Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Comstock, John Henry, 1849-1931.
