stored with spiders, and in one of them a specimen of Trypoxylon fugax of Fabricius. 

 The cells had been tenanted by a young brood of the Polistes before the Trypoxylon 

 took possession of them. This is certainly a very striking illustration of what I be- 

 lieve to be the habit of this genus of insects. 



" The nests and the Polistes were obtained by Mr. Clark at Petropolis, where, he 

 informs me, it is common." 



On the Habit of Chelostoma florisomnis. 



" I have received a letter from Mr. George Kearley, Blomfield Street, Finsbury, 

 in which he describes a singular habit of the males of Chelostoma florisomnis. Mr. 

 Kearley says : — 



" ' I send you half-a-dozen bees which I took last evening. They were resting in 

 a most singular manner on a dead branch of hawthorn that had been thrust into a 

 hedge to stop a gap ; the bees were attached to the points of the thorns by their man- 

 dibles, with their bodies stuck out straight and stiff in a line with the thorns, but quite 

 clear of them. Almost every thorn on one part of the bush was grasped by a bee. 

 They were attached so firmly, and were so loth to move, that it required a good shake 

 to dislodge them ; and when disturbed they immediately set about attaching them- 

 selves afresh. I broke off a twig and carried it to my residence, a quarter of a mile 

 distant, swinging it about, but not one of them relaxed its grasp. On going early to 

 the spot next morning I found the bush still thickly peopled with them, still attached 

 attached by the mandibles alone, the legs being folded under the body, the body itself 

 standing out stiff from the points of the thorns.' 



"This habit in the males of Chelostoma being new to me, I have thought it worth 

 recording in our ' Proceedings.' The bees were no doubt, as Mr. Kearley suggests, 

 settling themselves for the night. I have frequently found them huddled together by 

 half-dozens in the closed petals of flowers, but never in the manner above described.
