A simple half-cylin- drical trail, needle-like in size, running in straight or crooked lines, or cross- ing itself. Found in the upper part of the Kaskaskia Group, at the Whetstone quarries in Orange County, Fig. 1086.—Haplotichnus ludiuneiisls. The remains of insects found in the PaliEozoic rocks occur under such cir- cumstances as to induce the belief they were more or less aquatic in their habits, and frequented swamps and shores of bays and inlets. The Whetstone quar- ries of Orange County, Indiana, are yellowish white, slaty mud-rocks re- sembiing, in appearance, the Solen- hofen slates, but coarser in texture. They are limited in extent, and may be fairly presumed to represent tlie muddy shore of some bay or internal sea of Subcarboniferous age. Tiie slaty layers are covered more or less upon the upper surface with trail-furrows, and on the under surface with elevated lines, showing the trails were made in mud, which afterv ard hardened, and was then covered with a thin deposit of mud which was tracked and hard- ened and covered, and so on in one series after another throughout the whole thickness of the slaty deposit. Many of the living Dictyoptera are aquatic in their habits in the larva ;in(l pupa state, and it is not until the {ler- tect Insect is about to emerge from tlie skin of the pupa it creeps out of the Uiitei on the muddy shon' cr s
