The Coleoptera of Kansas and Eastern New Mexico (Classic Reprint) - Tapa blanda

Excerpt from The Coleoptera of Kansas and Eastern New Mexico

In the Central district, consisting, as it does to a very large extent, of deserts, the distribution seems to be of a moderate number of species over a large extent of country, with a considerable admixture of local species; such at least seems to be the result of observations in Kansas, Upper Texas, and Arizona.

Excerpt from The Coleoptera of Kansas and Eastern New Mexico

The present memoir is intended to give a catalogue of the Coleoptera thus far known to inhabit the middle eastern portion of the great central region of temperate North America. The boundaries of the province here treated of are as follows: north by the Missouri river, east by the meridian of the mouth of the Kansas or Platte river, south by about latitude 34°, and west by the main mass of the Rocky mountains.

It thus includes Kansas, a portion of Nebraska, and the eastern part of New Mexico. The eastern limit of this province is well defined; the other boundaries are indefinite, since it there fades imperceptibly into other provinces of the same great zoological district.

Before proceeding to consider the special material used in the preparation of this memoir, it will be proper to give a short sketch of the general results thus far obtained regarding the geographical distribution of Coleopterous insects in the territory of our republic.

The whole region of the United States is divided by meridional, or nearly meridional lines into three, or perhaps four, great zoological districts, distinguished each by numerous peculiar genera and species, which, with but few exceptions, do not extend into the contiguous districts. The eastern one of these extends. from the Atlantic ocean to the arid prairies on the west of Iowa, Missouri, and Arkansas, thus embracing (for convenience merely) a narrow strip near the sea-coast of Texas. This narrow strip, however, belongs more properly to the eastern province of the tropical zoological district of Mexico.

The central district extends from the western limit of the eastern district, perhaps to the mass of the Sierra Nevada of California, including Kansas, Nebraska, Utah, New Mexico, Arizona, and Texas. Except Arizona, the entomological fauna of the portion of this district west of the rocky mountains, and in fact that of the mountain region proper, is entirely unknown; and it is very probable that the region does in reality constitute two districts bounded by the Rocky mountains, and southern continuation thereof.

The western district is the maritime slope of the continent to the Pacific, and thus includes California, Oregon, and Washington territories.

These great districts are divided into a number of provinces, of unequal size, and which are limited by changes in climate, and therefore sometime distinctly, sometimes vaguely defined.
