In this paper are described various new species of insects, which although belong- 

 ing to one family, exhibit little apparent resemblance with any of its members, but 

 take the form of species belonging to other families, their affinity being with the 

 former, whilst their relation with the latter is that of analogy. The species and genera 

 here described are, 



1. Catascopus, belonging to the Harpalidae, but which " might be mistaken for a 

 species of Notiophilus of Dumeril, or at least be regarded as belonging to a cognate 

 genus." 



2. Pseudomorpha (fam. Scolytidas ?). Although this genus might at first sight 

 be regarded as a Nitidula or Ips, it possesses all the essential diagnostics of those Ca- 

 rabidae, with notched fore tibia?, but its precise place in that tribe is doubtful, although 

 it is suggested that it approaches towards Scolytus, Fabr. [Omophron]. 



3. Mimela (fam. Melolonthidae). This Chinese genus externally resembles the 

 Brazilian Areoda, " wearing, as it were, its very habit," but most nearly allied in struc- 

 ture to Euchlora. 



4. Agrion Brightwelli, apparently osculant between Agrion and Lestes. All these 

 insects are represented in a plate, executed by Mr. John Curtis. It is to be noticed that 

 the old Linnaean genera, transformed into families are here (in accordance with Mr. 

 W. S. MacLeay's plan, adopted in the ' Horas Entomological ') cut up into groups of 

 smaller value, to which the patronymic termination ' idae ' is affixed. 



20. ' Some account of a new species of Eulophus, Geoff roy.' Linn. Trans, xiv. 



pp. 111—113. Read December 17th, 1822. 

 This paper contains a careful description of both sexes of Eulophus damicornis, a 

 beautiful little Hymenopterous parasite with branched antenna? in the males, reared 

 from a caterpillar found on the hazel, which nearly, but not altogether, resembles that 

 of Bombyx camelina. 



21. ' On Animals receiving their Nutriment from Mineral Substances.' Tilloch 



and Taylor, Philos. May. and Journ. vol. lxi., 1823, Part I. pp. 3 — 4. 

 After alluding to the assertions of some writers that no mineral substances had 

 afforded food to any species of animal, the writer mentions that the late Mr. Hunne- 

 man had received four specimens of asbestos, from Bonelli, which upon examination 

 were found to contain many larvae of some insect that had perforated it in various direc- 

 tions, and in it underwent their customary metamorphosis, and which proved to be 

 Dermestes vulpinus. It was also mentioned as a proof that the insects had fed upon 

 the asbestos, that the holes with which it was perforated were of different sizes, varying 

 from l£ to 2 lines in diameter. 



22. ' Introductory address explanatory of the views of the Zoological Club,* de- 



livered at its foundation, November 29th, 1823, by the Chairman, the Rev. 



* This Club, which was at first a branch of the Linnaean Society, was subsequently 

 developed into the Zoological Society.
