their sibilant character from a desire to express the sound made by the Glossina 

 and (Estrus in iheir flight, just as the common names of certain birds are intended to 

 represent their peculiar notes. Mr. Weslwood expressed his regret at being obliged 

 to differ from so old and worthy a writer as Mr. Bracy Clark, but, having in vain ap- 

 plied to the editor of the ' Zoologist ' to publish a correction of the erroneous views 

 which had been promulgated in that journal, he was reluctantly compelled, in the 

 cause of truth, to come forward and support the statements which he had himself 

 published in the ' Proceedings of the Zoological Society.' 



The Rev. Hamlet Clark exhibited a series of Chrysomelidae, being a portion of the 

 collection recently made by him in the vicinity of Rio. 



Mr. Bond exhibited a pair of remarkable varieties of Apatura Iris, both specimens 

 being destitute of the usual white markings on the upper surface ; also a pale male 

 variety of Argynnis Paphia. 



Mr. Shepherd exhibited a specimen of Quedius dilatatus, taken by Mr. Sealy in 

 the New Forest, at sugar, which he had placed on a tree for the purpose of attracting 

 Noctuae ; he also exhibited a living example of Q. lateralis. 



The Secretary exhibited some seeds, apparently of a species af Euphorbia, con- 

 taining larvae, presumed to be lepidopterous, sent by W. G. Lettsom, Esq., H.B.M. 

 Charge d'Affaires, Mexico, with the following note : —

 « Sir, 



" As no scientific examination has, I believe, yet been made of the grub from 

 the motion of which the ' moving seeds,' from the neighbourhood of Tassic, in this 

 country, derive their celebrity, I send to you by the mail of this month a small box 

 containing a good many of these seeds, quite fresh, being of this year's growth. These 

 seeds are very lively, but that they should move about much it will be well to lay them 

 in the sun, or put them in a warm place. They only require to be scattered on some 

 smooth surface, when in a minute or two they will put themselves in motion. Should 

 the Entomological Society deem the grub worthy of a detailed examination, I shall be 

 extremely grateful if you would favour me with some account of their labours. 



" I am, &c., 



" W. G. Lettsom." 



Mr. Janson exhibited six living and forty-six mounted specimens of Drypta den- 

 tata, Rossi, Schatim (marginata, Fab., Steph., Dawson), captured a few days since in 

 the neighbourhood of Alversloke, Hants, by Dr. J. A. Power ; and also a fine series of 

 the same insect secured by himself on the same occasion. 



Mr. Waterhouse exhibited the following Coleoptera, from the collection of Dr. 

 Power: — 



Thiasophila inquilina. Two specimens, taken during the past summer, by their 

 indefatigable and successful owner ; one with Formica rufa, the other with F. fuli- 

 ginosa. 



Chlanius Schrankii. One specimen, recently secured in the Isle of Wight by 

 Mr. F. Bates.
