represented as far as Timor to tbe West, Manilla to the North, and New Zealand to 

 the South. It is also interesting from the remarkable structure of its mesosternum, 

 which is produced anteriorly into a sharp spine, overlappintj the prosternum. The 

 following characters separate the genus from Spintheria and from all other known 

 forms of Tmesislerninffi : — 



Anastetha, n. g. 

 Anlennoe setaceae, corpora lonjjiores. Prothorax basi latus et bisinuatiis, lobo scutellari 

 producto. Scutellum elongatum, angustatum. Femora posiica hand inorassata. 

 Mesosternum antice in spinam acutam projectum. 



Anasletha raripila, n. sp. 

 A. nigra, nitida, fere glabra, pilis argenteis perpaucis solum induta; elytris obscure 

 rubris, plaga subtransversa prope medium sita tertiaque parte apicali nigris, 

 apicibus ad suturam dentatis.

Papers read. 



Mr. Frederick Smith read a paper entitled " Notes on some Hymenopterous 

 Insects collected by Mr. Peckolt, at Catafjallo, South Brazil.'' Amongst ihem was the 

 Dielocerus Ellisii of Curtis, a sawfly which is social in all its stages, as described 

 by Curtis, whose accouut of its economy was corroborated by Mr. Peckolt; but the 

 most interesting object in the collection was the female of the stingless honey-bee, 

 Trigona, which has been a desideratum with hymenopierists. Amongst some hundreds 

 of specimens of Trigona Mosquito were a few workers and females, and of the latter 

 half a dozen examples; there was no difficulty in discovering the queen, which, when 

 her abdomen was distended with ef;gs, was more than double the length of a worker, 

 and had very much the appearance of a gravid female Terraes. The collection also 

 included Cryptocerus elongatus, which was said to be destructive to uesls of the 

 mosquito bee (Mr. Bates has described another species of Cryptocerus as feeding on 

 the dung of birds); and a white ant, very destructive to cofifee beans, closely 

 resembling, if not identical with, the Termes cumulans of Hagen. 



Mr. Robert Trimen, of Cape Town, communicated a paper entitled " Notes on the 

 Butterflies of Mauritius." Of the twenty species of Rhopalocera (exclusive of the 

 doubtful native, Thymele Ramanatek) enumerated by Boisduval in his " Faune 

 Entomologique de .Madaifascar, Bourbon el Maurice'' as inhabiting the last-mentioned 

 island, the author himself, during a visit of three weeks in July, 1865, captured 

 sixteen, and was presented by other collectors with the remaining four; in addition to 

 which he captured (bur species, and was ])resented with another, not known to 

 Boisduval as Mauritian. Tlie five additional species were Callidryas Fiorella, Fabr., 

 C. Rhadia, Boisd., Terias Rahel, Fabr., Junonia Rhadama, Boisd., and Libythea 

 Ciuyras, n. sp. P
