Mr. Stevens exhibited a spleiulid new longicorn beetle from Tana, New Hebrides, 

 for which Mr. Adam Wliite proposed the name of Psalidocoptus scaber. 



Mr. Westwood rea<l a note from a correspondent, who had found the larvae of 

 Meloe in immense numbers on potato-plants " hanging in clusters like swarms 

 of minute bees;" he also exhibited some of the larvse which had been forwarded to 

 him. 



Mr. Janson exhibited two specimens, one of which he presented to the Society's 

 cabinet, of Hypulus quercinus, Pai/k., taken by him on the same stump of oak which 

 yielded the species last year at Colney Hatch. 



Mr. Smith announced that Mr. Frederick Grant had recently discovered colonies 

 of Tapinoraa erratica at Wimbledon and Weybridge ; he also exhibited the female of 

 this species from the latter place, being the only British specimen of that sex hitherto 

 captured. 



Mr. Edward Sheppard exhibited three specimens of Drypla emarginata, found 

 by Mr. Arthur Adams under a tuft of grass near Portsmouth, but about two miles 

 inland. 



Mr. Stainton exhibited a number of very accurate drawings of the transformations 

 of Micro-Lepidoptera, made by Herr Grabovv, of Berlin, among which the most 

 interesting was that of Asychna ajratella, which feeds iu a pod-like excrescence which 

 it appears to form on the shoots of Polygonum aviculare, in autumn. 



Mr. Hunter exhibited a female Stauropus Fagi, recently taken at Black Park, and 

 also the young larvae about thirty-six hours old, produced from eggs laid by this 

 specimen. 



Anommatus and Langelandia. 



The President stated, with reference to the communication made by him at the 

 last Meeting from Mons. Charles Delarouzee, that he had recently been informed by 

 that gentleman that the waler-butt alluded to was sunk in the earth to the depth of 

 three feet, which would account for his having found the insects then mentioned three 

 feet below the surface; he added, that he had no doubt, by searching in similar situa- 

 tions in this country, we might discover both Anommatus and Langelandia. 



Observations on the Habits of two species of Mygale. 

 Under the above title, Mr. Smith read the following notes, by Mr. H. W. Bates : — 



"With regard to spiders, there is one observation I made, which I am sure will be 

 of the highest interest to Science : it is with respect to the habit of the genus 

 Mygale to prey on birds. Now, I have detected them in this fact as far back 

 as 1849, but thought little of it at the time, as I had the idea that it was a well-known 

 and undisputed fact in Science. Lately, however, I read an account (T think, 

 in ' Langsdorffs Expedition in the Interior of Brazil'), where the fact is considered to 

 rest on no foundation, and to be one more of the fables originated by Madame 

 Merian. 



"Now, I will relate to you what I saw in the month of June, 1849, in the neigh- 

 bourhood of Cameta ; I was attracted by a curious movement of the large gray-brown 

 Mygale on the trunk of a vast tree : it was close beneath a deep crevice or chink in 

 the tree, across which this species weaves a dense web, open for its exit and entrance
