The antennae (Fig. 530) are shorter than the thorax, and composed of short, broad, and closely-pressed-together segments. Although the an- tennae are hairy, they are not furnished with whorls of long hairs in the males, as is the case in most of the preceding families. These insects resemble the fungus-gnats in having ocelli; but they differ from them in the shortness of the antennae and in the fact that the coxai are not greatly elongate. In

In this family and the following one the eyes of the males are in many cases contiguous. The venation of the wings of the typical genus is represented by Figure 531. Fig. 529.—Bibio.
