Exhibitions, dc. 
‘Mr. F. Smith exhibited some remarkable specimens of thorns from 
Natal and Brazil, which had been taken possession of by certain species of 
Oryptoceride for the construction of their formicaria: some of them were 
as much as three inches in length. ‘ 
Mr. Champion exhibited a bug sent by Mr. Walker from Besika Bay. 
It was figured in Guerin’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 antenne: 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 Keuador, which was found 
to contain nine living specimens of cockroaches, comprising six different 
species, viz., Blatta orientalis, Americana, cinerea, Madera, and two others 
unknown to him, some being of considerable size. 
Professor Westwood alluded to the varied nature of the collection recently 
exhibited at the “ Exposition des Insectes utiles et des Insectes nuisibles,” 
in Paris, and remarked on the absence in the list of exhibitors of the names 
of many distinguished French entomologists.
