Rh The female (Fig. 33) appendages consist of two bodies conjoined at their bases, and blunt at their free extremity. When viewed from one aspect they appear cylindrical, but, from the other, flattened or even concave; opposite to the latter face there is a broad, irregular piece, which has its free extremity scolloped.

The general color of this species is brown, but there is a series of lateral black dots around which the color is often much lighter. There is a pair of punctations on the vertex, which is traversed by a broad blackish band. The inferior portion of the head is light brown, often mottled. The labrum is moderately emarginate. Each scutum is furnished with a series of rather distant puncta, from each of which proceeds a more or less obsolete superficial groove.

The male appendages (Fig. 34) are composed on each side of two parts attached to the basal piece. The outer of these is nearly straight, though somewhat rolled on itself, and is distally enlarged and pilose. The inner part is formed chiefly of a thin, straight piece, very much rolled and twisted. Distally it is expanded into a very thin, transverse, diaphanous, alar process, with serrated edges.
