JULY 22nd, 1920. 



The President exhibited Cimex pipii^trellns, the Hemipteron 

 which infests the bat, and contributed the following note: — 



" Cimex pipisti'elliis closely resembles C. lectiilaritts, but has 

 wider flat margins to the prothorax and is clothed with longer 

 hairs. The species is, as its name implies, panisitic on bats. This 

 specimen with others was found in a bathroom, but it was found 

 that bats were breeding immediately above. That it can and^vill 

 draw blood from a human host is established, but that it will thrive 

 on such diet is rather doubtful. At any rate a ? that was given 

 such a meal on 31st May last was dead a few days later. A 

 freshly developed ^ was fed on the same day and on July 21st 

 was also dead. On the other hand the 3' exhibited had 

 developed after feeding as a nearly mature nymph, as also has 

 the $ now exhibited. Some young nymphs hatched from 

 the egg have fed, but have not yet reached the second instar. 

 When feeding, either nymphs or adults, no sensation is noticeable 

 and no inflammation or irritation follows, a very different result 

 from that following the bite of (J. lectularins." 



Mr. Pririke recorded a remarkable occurrence which befell some 

 traps for Coleoptera which he had set in Richmond Park. Five 

 out of six traps set contained a distinct species of Necrophorus, viz.^ 

 N. iiiortHornin, N. humator, N. vespillo, N. ruspator, and N'. inter- 

 ruptus, whilst in the sixth trap were two species of Silpha. 



Mr. Newman reported that he had bad luck with his larvae 

 of Phryxtts livornica, the whole batch having died when full-fed, 

 and he had heard that those retained by Mr. Hedges had also 

 perished, whereas Mr. Bright, who only had about a dozen, had 

 successfully got them into the pupal stage. 



He reported that he had found Atgynnis aylaia abundant, and 

 Plebeiiis aeijon in fair numbers ; that Melananjia yalatliea had appa- 

 rently gone from W. Kent, whilst Pyrameis atalanta had again 

 appeared; that the 2nd brood of Rumicia phlaeas was out; and 

 that nearly everything he had in captivity was making a second 

 brood.
