Fig. 1. Anophthalmus telllcampfii Erichs. (Emerton del.) — "The figure is a poor one ; the antennae, head, and thorax, and on the elytra the characteristic pair of sensitive hairs is entirely omitted ; all other species have three sensitive hairs on each elytrum " (E. A. Schwarz in letter).

Fig. 2. Anophthalmus tenuis Horn

Fig. 3. Anophthalmus eremita Horn, Little Wyandotte Cave. — " A tolerably fair representation ; the last joint of the maxillary palpi should- be longer than the penultimate, and some indication of the elytral striae ought to be given " (Schwarz).

Fig. 4. Anophthalmus menetriesii Motsch. (Emerton del.) — " This is a fair representation, except that the antennas are altogether too heavy" (E. A. Schwarz).

Fig. 5. Anillus explanatus Horn, (copied from Horn). — The antennae drawn by lithographer too stout and the setae too coarse.
