One v/as picked up in theblow sand beside a large area of bare sand. Others were taken underlogs in bunch-grass and in blow-sand, indicating that the log habitatis self-contained, to a certain extent. Chauliognathus pennsylvanicus De G. A yellow soldier beetle with an elongate black spot covering theend of each elytron, except for the margin. The larvae hatch in late summer, pass the winter in a nearly full grown stage, feed ravenously. 12 in spring, pupate, and become adult in summer. The larvae are pre-daceous, eating all kinds of soft-bodied insects: the adults feedupon the honey and pollen of various flowers. Chauliognathus israre in the sand region, while very abundant in black soil prairieregions of other parts of Illinois. It is usually found on flowers,in company with the black blister beetle, Epicauta pennsylvanioa. Podabrus tomentosus Say. June 24. Very common in other parts of the state, but rare in the specimen, taken in flowers along a sandy road side. Trichodes nuttalli Kirby. August 13. Specimens of this clerid were taken on Eupatorium perfoliatumin the sandy region of the lake shore at V/aukegan, Illinois. Blatohley records it from Porter, Kosciusko, Elkhart, and Crawford countiein Indiana; the first three counties are largely sandy. As the Por-ter county specimens were taken in flov/ers of Opuntia, in an associ-ation similar to the Illinois ri
