The discussions upon the subject of nomenclature in Zoology, and especially in the department of Entomology, have recently become very perplexing to American students. Many who have been unable either by want of time or lack of opportunity, to consult old works, which are to be found in but few libraries, are called upon suddenly to decide for themselves, whether they will or will not adopt changes in the names of some of the most familiar and best known objects.

The insect-catching powers of those curious plants, the Fly-traps (Dionæ), the Sun-dews (Drosera) and the Trumpet-leaves (Sarracenia) have always attracted the attention of the curious, but renewed interest has been alvakened in them by virtue of the interesting experiments and observations on their structure, habit and function, that have lately been recorded, and especially by the summing up of these observations in some charming papers by Prof. Asa Gray, which recently appeared in The Nation and The New York Tribune, under the title of “Insectivorous Plants.”

The specimens are hardly to be distinguished from Eastern material; they are perhaps a little larger, and of a little different tone of color. My determination of this species as lycarum H.-S., based on a figure, is probably incorrect. It seems possible that Harris has described. A. Cochranii under the name messoria, which should then be retained. More Material of A. fuscigerus (ante No. 15) shows that this is a good but variable species, both in size and color. There is always a uniformity in the disposition of the ground tint over the primaries above, and usually the broad inner lunulations of the t. p. line and the median shade are characteristic.

This species was bred from minute mines in the leaves of Persimmon trees (Diospyros virginiana),gathered in great abundance at the “Bee Spring” camp of the Kentucky Geological Survey, in Edmondson County, a few miles west of the Mammoth Cave. I have never met with it in Northern Kentucky, where the Persimmon tree also grows, but is comparatively rare.
