The first extensive contribution to a knowledge of the anthomyid flies of North America was made by Francis Walker in 1849, when he published the records of fifty-five nominal species in his list of dipterous insects in the British Museum.

Bohart (1965) treated the identity of 100 names of North American Eumeninae described by Peter Cameron from 1905 to 1912. This paper established the synonymy of all but four of these names, and so solved many problems in the nomenclature of nearctic Eumeninae. During a recent visit to the British Museum, I studied the type specimens of two of the unrecognized species, and in the present work establish their synonymy.

Late Professor

BY far the larger proportion of the Carboniferous fossils described and figured by the late Professor John Phillips, F.R.S., in the second volume of his “Illustrations of the Geology of Yorkshire,” and published in 1836, are contained in the collection of the late Mr. Gilbertson, of Clitheroe, now deposited in the Geological Department of the British Museum. The early date of publication of this work renders the collection described in it one of the most important, next to those of Sowerby, Ure, Martin, and one or two others, to students not only of British, but equally so of Continental Carboniferous Palæontology. Unfortunately the descriptions of Prof. Phillips are so abbreviated and unsatisfactory, and the figures in many instances so mearge, that it is with great difficulty anything like an accurate determination of a species can be made by the aid of them. Under these circumstances the following notes made directly from the type specimens will probably be found of use; it would, however, be far more satisfactory to have the specimens refigured. For convenience sake I shall commence with those composing plate vi., and then take the others composing plate v.

Theoretical Risk

Two types of porcine reproductive and respiratory syndrome virus (PRRSV) exist, a North American type and a European type. The co-existence of both types in some countries, such as Denmark, Slovakia and Canada, creates a risk of inter-type recombination. To evaluate this risk, cell cultures were co-infected with either a North American and a European type of PRRSV or two diverse types of European isolate. Subsequently, an approximately 600 bp region of the PRRSV genome was tested for recombination by quantitative real-time RT–PCR. Between 0·1 and 2·5% RNA recombination was found between the European isolates, but no recombination was detected between the European and North American types. Calculation of the maximum theoretical risk of European–American recombination, based on the sensitivity of the RT–PCR system, revealed that RNA recombination between the European and North American types of PRRSV is at least 10000 times less likely to occur than RNA recombination between diverse European isolates.

The Subject

The material here described was mostly obtained as a result of a period of study and travel in East Africa in 1939. Two of the species were reared from Coccidae of the genus Aspidoproctus at Amani, Tanganyika Territory, and their life, history is the subject of an accompanying paper. I am greatly indebted to Dr F. W. Edwards, F.R.S., for allowing me to describe the remarkable species collected by him on Ruwenzori, Uganda, in 1935. I am also most grateful to Dr R. H. Le Pelley of the Scott Agricultural Laboratories, Nairobi, and Dr E. A. Lewis of the Veterinary Research Laboratory, Kabete, Nairobi, for other valuable new material. In addition, The Imperial Institute of Entomology has kindly allowed me to examine and describe material from Uganda in their possession which had been erroneously identified as Cryptochaetum iceryae (Will.). Type specimens of all species will be deposited in the British Museum.

North American Type

Porcine reproductive and respiratory syndrome virus (PRRSV) is still one of the most important infectious diseases threatening the swine industry. To construct North American type II PRRSV infectious clone containing green fluorescent protein (GFP) gene, we amplify gfp gene, flanked by PRRSV Nsp2 gene fragments upstream and downstream, using overlap PCR method from pcDNA-EF1-GFP plasmid and FL12 plasmid containing PRRSV infectious genome as the templates. The Nsp2 fragment-flanked gfp gene was inserted into Nsp2 gene of the FL12 plasmid bySpeI andXhoI sites to generate PRRSV infectious recombinant plasmid (FL12-GFP) containing gfp gene. The recombinant PRRSV expressing GFP (PRRSV-GFP) was rescued in baby hamster kidney-21 (BHK-21) cells by transfecting PRRSV mRNA synthesizedin vitroand amplified in Marc-145 cells. The PRRSV-GFP infectivity and replication capacity were identified. Results showed that, by adopting overlap PCR strategy, the gfp gene was successfully inserted into and fused with PRRSV Nsp2 gene in the PRRSV infectious clone plasmid FL-12 to generate FL12-GFP plasmid. The recombinant PRRSV-GFP was generated through transfecting PRRSV mRNA in BHK-2 cells. Like its parental virus, the recombinant PRRSV-GFP maintains its infectivity to Marc-145 cells and porcine alveolar macrophages (PAMs). This study provides essential conditions for further investigation on PRRSV.

Hübner ([1824-25] p. 357) defined the genus Epipagis, citing three species. Hampson (1918: 277) chose fenestralis Hübner as type, and sank Sameodes Snellen to Epipagis. The arrangement of the British Museum Pyralidae shows that Hampson thought fenestralis Hübner was the same as phyllisalis Walker; but so far as I know this synonymy was never published. Actually, Hübner's figure of fenestralis represents a female of the genus usually known as Stenophyes Lederer, wrongly synonymized by Hampson (1899) with Crocidophora Lederer. The size and coloration suggest that the species Hübner figured is the common North American one universally called buronalis Guenée.

A Re-Examination of the type-specimens of “Sclerostoma” clathratum Baird from the African elephant, which are in the British Museum, has led to a rather interesting discovery. The material was contained in two bottles, labelled in Baird's own handwriting. One bore the name “Sclerostoma clathratum Baird,” and contained a single male specimen of the form now known as Grammocephalus clathratus. The other bottle was labelled “Sclerostoma clathratum Baird, ♀,” and proved to contain worms of both sexes and of quite a different type from Grammocephalus.

The Gazophylacium of Jacob Petiver, Apothecary in London (died 1715) is a very rare book, as the plates and the catalogues were printed and published at different times between 1695 and 1715. They were collected later and published by Mr. Empson, an officer of the British Museum and a natural son of Sir Hans Sloane, in 1764, in London, with the title, “Jacobi Petiveri Opera, etc., or Gazophylacium, 2 vol. fol.” A small volume in 8vo contains the original sheets published by Petiver between 1695 and 1706. The library of the Museum of Comp. Zool. at Cambridge possesses a copy presented, June 1765 by Emanuel Mendez da Costa, Librarian of the Royal Society, to Thomas Knowlton. The collection of J. Petiver, at least the Lepidoptera, is still preserved in the British Museum, and was seen by me in 1857. Every butterfly is placed between two thin plates of mica, fastened with a small band of paper around the margin, and glued with one flying slip to the pages of a book in quarto, so that every species can be examined above and beneath.
