The two subfamilies may, I believe, be farther separated by the fact that the Cheliferinœ have the dorsal scutæ of the abdomen divided by a median line; while in the Obisinœ the scutæ are entire. Chernes pallidus, Banks which was descirbed as having the median line wanting, really has a median line, through on account of the light colour of the abdomen it is very difficult to trace. The Cheliferinœ have an apophysis or small stylet near the end of the mandibular finger.

As I was in the habit of sending to the authorities, for determination, only such as I had in duplicate, thereby avoiding the inconvenience of returning them, and retaining single specimens of a kind as a reminder of what at look for, and in most cases where to look for them, I found that in Micros single specimens accumulated rapidly. Having changed my location, I wished to finish up with the old material and begin anew.
