pursued to bore into the heart of the tree so rapidly as to 

 almost defy capture; also on the sense by which they are 

 enabled to locate trees soon after being felled. The perspira- 

 tion of the human body serves to attract them in no slight 

 degree, and especially is this so at the approach of dusk. 



Mr. Buchholz stated that numerous specimens of a Prionus 

 are sometimes present on the walks in Arizona, where their 

 dead bodies frequently render the pavements slippery. 



Mr. Bischoff said that he found many larvae of Lncanus daina 

 boring into the roots of an unidentified tree. They were pres- 

 ent throughout the roots as far into their ramifications as 

 their thickness would allow. 



Mr. Brehme read a paper on his experience in collecting 

 dragon-fly larv?e. In his search for mosquito larvae he dis- 

 covered several small depressions in the bed of a flowing 

 stream, and in these hundreds of specimens were taken in a few 

 hours. In one instance eleven examples were secured with a 

 single dip of a small hand net. 



JOHN A. GROSSBECK, Secretory. 



The January meeting of the Newark Entomological Society 

 was held at Turn Hall on January 10, 1908, with seventeen 

 members present. 



Mr. Grossbeck spoke on the life habits of dragon-flies in 

 general. He believed that the large eyes of the nymphs served 

 as little more than cases for the developing compound eyes of 

 the adult, since experiments carried on by him showed that 

 they were unable to differentiate between the animate and 

 inanimate and repeatedly grasped small sticks and leaves 

 twirled near them with a medicine dropper. A small Curcu- 

 lionid beetle was struck at whenever it was forced within reach 

 of the extensile labium, but as soon as it was stunned and 

 remained quiet it was left unmolested, though put directly 

 against the jaws of the nymph; again, the beetle recovering, 

 it was immediately snatched. 



Supplemental to Mr. Grossbeck's remarks Professor Smith 

 outlined the peculiar manner in which copulation was effected.
