OBITUARY. 



Charles G. Siewers died at his residence, Newport, Ky., Sept. 6th, in 

 the 68th year of his age. For many years he has been a devoted and en- 

 thusiastic student of entomology. He spent much time in rearing the 

 larvae of Lepidoptera, making colored drawings of them through their 

 stages of growth. He collected largely in Coleoptera and was a very 

 accurate observer of habits. It is due to his skill as a collector that some 

 of the rarest species have been recorded as occurring in this locality.

ON THE MOUTH OF THE LARVA OF CHRYSOPA. 



(By William Saunders, London, Ont., read before the A. A. A. S., at Montreal.) 



Recently I had the opportunity of watching in a live box, under a low 

 power of the microscope, the seizing and devouring of some plant-lice by 

 the larva of an undetermined species of Chrysopa, and was interested in 

 the manner in which it emptied the body of its victims. The jaws are 

 large, hooked, pointed and tubular, with a small opening at or near the 

 points. Approaching its prey the body of the Aphis is grasped by the 

 hooked mandibles which at the same time pierce it. The Chrysopa larva 

 remains stationary, and proceeds to pump its victim dry. At the base of
