200 reach about to the base of the filiform bodies, and have a slit-like orifice in their summit.

Length of body, 2½ inches.

I have seen specimens of this species and written a detailed description, which was destroyed at the Smithsonian fire. At present I am unable to obtain any specimens, and therefore am forced to give only a specific diagnosis from memory. Length, 2 inches. Fig. 32 is a drawing of the female organs.

The color of all our specimens is a very dark reddish brown, unrelieved by any other tint. On the vertex is a pair of coarse punctations, as in I. Canadensis, The lateral processes of the first scutum in the female, although small, are somewhat canaliculate. The mucro is certainly smaller than that of I. Canadensis. The male appendages are composed of two parts. The outer of these consists of a somewhat clavate and pilose process, with a curiously folded and contorted plate on its inner side. The other portion is formed of a straight process, which has several minute, spine-like bodies on its free extremity, and is proximally suddenly contracted, and then expand somewhat, so as to give an appearance of emargination. From the base of this springs another, almost filamentous process.
