incanum (L.) Michx. proves attractive to Rhipiphorus limbatus 

 Fab., as well as to certain other forms which however do not 

 show special preference to the Labiatse. 



During the summer eleven species of the family Cleridse were 

 taken, six species being of the genus Hydnocera Newm. With 

 their food plants and dates, they are as follows : H. pallipennis 

 Say (July i6-Sept. 16) on Carya glabra Spach., C. alba K. Koch., 

 Juglans cinerea L. and Platanus occidentalis L. ; H. humeralis 

 Say (Aug. i), H. longicollis Ziegl. (July 15-24), and H. verti- 

 calis Say (July 16-17), all from Carya glabra Spach., and H. 

 lecontei Wolc. (June 14-15) was found on Be'tula populifolia 

 Marsh and Verbascum thapsus L., although this species probably 

 came from a nearby stand of Carya glabra. Of the other genera 

 collected, one specimen of Monophylla terminata Say was taken 

 from Vitis labrusca L. on July 15, and, from Carya glabra, three 

 specimens of Ellipotoma laticornis Say (July 16-17) and one 

 specimen of Phyllobcenus dislocatus Say on July 16. Trichodes 

 nutalli Kirby was found between July 30 and August 4, on the 

 flowers of Taraxacum officinale Weber, Daucus carota L., Pycn- 

 anthemum incanum, (L.) Michx., and Chrysanthemum, leucan- 

 themum L. The remaining species, Necrobia violacea L. was 

 uncommon under the almost cleared skeletons of hens. 



An interesting incident bearing on the instincts of myrmecopil- 

 ous Coleoptera came under my observation one afternoon while 

 returning from a collecting trip. A large brown ant (species 

 unknown) was dragging an apparently dead beetle across a path. 

 Stooping to pick the pair up for examination, I was much sur- 

 prised to have the beetle take immediate flight from my hand. 

 This flight was arrested by the net and the beetle proved to be 

 the well known myrmecophile, Cremastochilus canaliculatus 

 Kirby. The abduction by the ant did not disturb the beetle 

 nearly as much as the outside interference. The most interesting 

 part of the whole afifair is the fact that the ant was still clinging 

 to the fore leg by its mandibles. I wonder if the beetle would 

 have stopped as soon as possible and allowed the ant to resume 

 the interrupted journey.
