Experiments Avitli oils. &e., for bait-traps to attract beetles, 

 without result. Aerial movement of beetles influenced by 

 topography, trees, soils. Effect of extreme lieat on beetles on the 

 feeding-trees; large numbers found dead on ground.

Investigation of Ovipositing; unsuccessful, only one set of 

 13 eggs found. Dissection showed that 24 eggs matured at one 

 time. Sketch of light-trap for beetles is included with notes on 

 number captured, which was very small.

Larvicides tested: (1) creolin, (2) cyanide of potassium, 

 (3) borax, and (-i) creosote all proved deadly to the grubs, but 

 too expensive for general use. The solutions of saltpetre, barium 

 chloride, and hellebore, on the other hand, were not eft'ecti\c.
