Cryptoccridic for the construction of their formicaria : some of them were 

 as much as three inches in length. 



Mr. Champion exhibited a bug sent by Ur. Walker from Besika Bay. 

 It was figured in Gucrin's Mag. de Zool. under the name of Mustha 

 spinosula. 



Professor Westwood mentioned that a caterpillar had been forwarded to 

 him from Deal, the captor complaining that he had suffered from considerable 

 irritation of the skin, caused by the hairs of the insect, and that the irritation 

 had continued for a week afterwards. It was the larva of Lasiocampa rubi. 



The Professor exhibited a singular Coleopterous larva, from Zanzibar, of 

 a flattened, ovate form and a steel-blue colour, with two points at the 

 extremity of the body and with long clavate antennts : the head bore some 

 resemblance to that of the Dipterous genus Diopsis. He also exhibited a 

 specimen of the butterfly Hesperia Sylvanus, received from the Rev. Mr. 

 Higgins, of Liverpool, having the pollinaria, apparently of an orchid, 

 attached to the base of the tongue. Also the bulb of an orchid, purchased 

 by Mr. Hewitson with a collection of roots from Ecuador, which was found 

 to contain nine living specimens of cockroaches, comprising six different 

 species, riz., Blatta orientalis, Americana, cinerea, Maderae, and two others 

 unknown to him, some being of considerable size. 



Professor AVestwood alluded to the varied nature of the collection recently 

 exhibited at the " Exposition des Insectes utiles et des lusectes nuisibles," 

 in Paris, and remarked on the absence in the list of exhibitors of the names 

 of many distinguished French entomologists. 



Mr. Dunning read the following : — 



Note oil Acentropus. 



" In the Transactions of the Entomological Society of the Netherlands 

 for the present year (Tijd. v. Entom. xix. 1), Heer Ritsema has published 

 a Second Supplement to his ' Ilistorical Review of the genus Acentropus;' 

 and the author, writing in June, 1875, prefaces it with the welcome 

 announcement that he has worked up the literature to the present time, 

 * as in all probability I shall be able in this summer to complete the history 

 of the mode of life and the different stages of A. niveus.' 



" "Whether this expectation has been fulfilled, either in 1875 or 187G, 

 I do not know. But, however this may be, I am sure Heer Ritsema will 

 be glad to learn that, though he and I failed to convince Newman that the 

 genus is properly placed in the Lepidoptera, we did make a convert of 

 Doubleday. In a Supplement to his ' Synonymic List of British Lepi- 

 doptera,' published in 1873, Doubleday for the first time admitted 

 Acentropus into that order. Its precise place in the order is not indicated, 

 but it is immediately followed in the Supplement by a species of Ebulea
