Later, Pro/. P. R. Uhler placed the species in a new genus 

 and redescribed it as Belonochilus 7zumenius Say.* 



The following November, Mr. J. Kotinsky showed me some 

 sycamore fruits taken at Eckington, November 12, on which he 

 had observed the young larva of a bug. The larva proved to be 

 identical with those I had found previously in early summer on 

 the same kind of trees. 



On December 8, I took from the sycamore trees, on which I 

 had collected the insect in the month of June, a number of the 

 fruits, which dangle so conspicuously from long peduncles at 

 tached to the bare twigs, and I found on nearly every one of them 

 a colony of the larvae. The ball-shaped fruit, known to botanists 

 as a head, is composed, as is well known, of the ovaries contain 

 ing the ovules or seeds. In the crevices or interspaces among 

 the ovaries gathered on the head, the larvae hide, head jlown- 

 ward, in a dormant state, congregating conspicuously on the 

 underside of the fruit, probably adopting this place as the best 

 shelter against the severity of the weather. 



Upon warming the fruit of the sycamore with my hand the 

 bugs hidden on it soon recovered from their dormant state and 

 crawled around actively. The larva can hardly be detected in 

 its hiding place, because it matches in color perfectly with its 

 surroundings. 



While Belonochilus numenius Say may live also on other 

 food-plants, these observations at least establish the fact that it 

 lives on sycamore, and also that it has two annual broods, the 

 fall brood hibernating in the larval stage on the underside of the 

 globose heads. 



Mr. Kotinsky, in discussing the paper, said that the larvae on 

 these heads, when exposed to the rays of the sun, would move 

 around, apparently seeking to find shelter. 



Dr. Howard's paper, entitled " Some Additional Mosquito 

 Notes," then followed. It consisted of the most interesting facts 

 taken from the large mass of information on this subject which 

 has accumulated, through correspondence and otherwise, since 

 the publication of his "Notes on the Mosquitos of the United 

 States."! 



These additional notes are soon to be published. The paper 

 was discussed by Messrs. Gill and Hay.
