1. Field Observations on the Habits of the Species , by R. Weith. Nannothemis bella , Uhl., is one of the smallest of dragon-flies. Of its life-history we have had no knowledge up to the present time. Until the publicetion of Williamson's Catalogue of the Dragon-flies of Indiana, last year, it was recorded only from our north-east Atlantic seaboard. I have frequently met with it in Elkhart and St. Joe Counties, the two northermost counties in Indiana; but, what has been most perplexing to me, only in a few very restricted areas, these areas not exceeding 50 yards in length by 25 yards in width from margin of lake. The only places I have met with it are at Simonton Lake, a distance of four and one-half miles from the City of Elkhart, Indiana, and Indiana and Baldwin Lakes, thirteen miles north-east of Elkhart, on the boundary line that divides Indiana from Michigan. In the latter place, on a smaller area than at Simonton Lake, the imago is very numerous. Frequent endeavors to find the species at other places where similar conditions prevail proved unsuccessful.
