THE ENTOMOLOGIST S EECORD. 



F.L.S. — Living specimens of Ovivorous parasites {Mymar'nlae), 

 together with larvfe and piipjB, in the eggs of Libtirnia (Froghoppers). 

 Eecent research into the economy and life-history of these microscopic 

 insects, shows that they are most fastidious in their choice and 

 identity of their "host eggs, "one species of ^/rty/f/f.s ovipositing in the eggs 

 of a certain species of Fsncus, while the delicate Anca/n make diligent 

 search for the minute eggs of some of the Froghoppers. Examples 

 of eggs of Libtirnia were shown containing from one to six Anaf/ri in 

 an advanced state of development. (2) Lieut. -Colonel Bruce, F.R.S. — 

 Tri/pauosoma theileri — a new species of parasite, discovered in the 

 blood of cattle in South Africa. This new TrijiHotosniiia was lately 

 discovered by Dr. A. Theiler, who is in charge of the Bacteriological 

 Laboratory of the Medical Officer of Health, Pretoria, Transvaal. 

 The species can be at once distinguished from the Trypanosomas of 

 Surra, Tse-tse Fly Disease, or Rat by its larger size, it being almost 

 twice as large as any of the others. In general appearance it conforms 

 closely to the others in possessing an oval protoplasmic body, a 

 ongitudinal fin-lil^e membrane, and a single Hagellum. It only infects 

 cattle. Horses, dogs, goats, rabbits, and guinea-pigs are all immune, 

 neither showing symptoms nor the presence of the parasites in the 

 blood. (3) Mr. -J. Everett Dutton, M.B., on behalf of the School of 

 Tropical medicine, Liverpool. — Specimen of a Trypanowina found in 

 the blood of man. The Tri/panosoiiia was first discovered in the blood 

 of a European in Government employ at Bathurst, West Africa. The 

 presence of the parasite was associated with symptoms closely 

 resembling those occurring in animals suffering from tsetse fly disease. 

 The parasite was again found in a preparation of blood taken from a 

 native child at Bathurst. We noticed, among other entomologists 

 present at the Conversazione, Messrs. A. J Chitty, W. L. Distant, 

 H. St. J. K. Donisthorpe, H. Druce, H. .J. Elwes, H. Goss, 

 R. McLachlan, H. Rowland-Brown, C. 0. Waterhouse, Professors 

 Meldola and Poulton and the Rev. Canon FoAvler. 



A meeting of the Entomological Club was held at 58, Kensington 

 Mansions, on May 5th, Mr. H. St. J. K. Donisthorpe being the host, the 

 guests being received by Mr. and Mrs. Donisthorpe. Among the 

 guests present were Messrs. R. Adkin,F. Bouskell, M. Burr, H. Rowland- 

 Brown, A. J. Chitty, J. Collin, T. W. Hall, W. J. Kaye, G. T. Porritt, 

 G. H. Verrall, E. A. Waterhouse, and Colonel E. Swinhoe. After tea 

 and cott'ee had been served the members adjourned to Mr. Donisthorpe's 

 museum, where the host's collection of British coleoptera was 

 inspected, and his system of labelling duly appreciated. His observa- 

 tion nest of Formica riifa, in which the life-history of Chjthra 

 quadripHnitata has been worked out, attracted much attention. Mr. 

 A. J. Chitty exhibited specimens of Khiiis ciohurKu from Scotland, also 

 Dt/tiM-iis circtiuiji(\nis, etc. Supper was served at 9 p.m., and one was 

 strongly reminded of the olden times when these meetings were so 

 thoroughly enjoyed by an earlier generation of members. Altogether 

 one of the pleasantest meetings that have been held, was the eulogy 

 passed on it by the guests. 



Messrs. Scudder and Cockerell give us a First List of the Orthoptera 

 of New Mexico, in the Proceedings of the F>ai'cn})ort Acadeiinj of Sciences, 

 Davenport, Iowa, 1902, vol. ix. In an interesting preface the authors 

 discuss the geographical distribution within New Mexico, considering 

 the life-zones and discontinuous distribution, also the food-plants ;
