 Ceratopogoninae.— .4;'r//. Inst. Pasteur Afr. Nonl, Algicys, 

 i, no. 1, Clinch 1921, pp. 107-115, 6 figs. 



A key is given to certain genera of Ceratopogoninae allied to 

 Leptoconops. The species described include Microconops vexans, 

 gen et sp. n., Tersesthes camelormn, sp. n., and Cnlicoides {Diplosclla) 

 sergenti, subg., and sp. n., all taken on camels in Algeria ; Holocvnups 

 transversalis, sp. n., from Tunis ; and Culicoides cordatus, sp. n., from 



Courland. . . , .-i-j. 



Other new genera erected are Lasiohelea, for Atrichopogonpilosipennis, 

 Kieff. ; Gvmnohelea, for A. singiilaris, Kieff., and A. longiserra, 

 Kieff. '; Protersesthes for Tersesthes brasiliensis, Lutz ; and Styloconops 

 for Leptoconops albiventris, Meij. {spinosipes, Kieff.). 



LouGHNAN (W. F. M.). Unclassified Fevers in Jamaica.— J/. Prop. 



Med. & Hvg., London, xxiv, no. 13, 1st August 1921, pp. 201- 



204. 

 The etiology of various unclassified fevers is unknown, but they are 

 probably protozoal in origin. There are at least three types of such 

 fevers in Jamaica, and these are here described. Culicoides macidi- 

 thorax is the most common blood-sucking insect in the island. It is 

 ubiquitous and may be a vector of sand-fly fever. Simulium has been 

 found, but not where the fever is prevalent.

 the Ox-Warbles Hvpodenua bovis and Hypoderma lineatuni, with 

 Description of a new Larval Stage.—//. Agric. Res., Washington, 

 D.C., xxi, no. 7, 1st July 1921, pp. 439-457, 24 figs. 



The value of the posterior stigmal plates and other characters for 

 differentiating the four known larval stages of Hypoderma lineatuni, 

 De Villiers, and H. bovis, DeG., is discussed, and a new larval stage 

 of H. lineatum in the oesophagus of the host is described.

 Congo Beige, Brussels, xii, no. 2, June 1921, pp. 294-302. 



In an earlier paper [R.A.E., B, v, 12] the author expressed the 

 opinion that pathogenic trypanosomes can be transmitted in nature 

 from one animal to another by blood-sucking Diptera other than 

 Glossina, and this has subsequently been confirmed by other observers. 

 A severe epizootic of trypanosomiasis has recently broken out in 

 Ruanda, where the altitude in many districts is above 4,600 ft. and 

 where Glossina does not occur. The disease, which was unknown 

 there a few years ago, seems to have been introduced by the mules 

 used by the troops in the war, and has spread throughout the region. 

 The trypanosome is pathogenic to cattle, sheep, guinea-pigs and 

 probably to equines, and investigation has shown that it is identical 

 with T. congolense-pecortim. Though Glossina is absent, Stomoxys 

 spp. occur at certain times in great numbers. Many of these flies 

 that had recently fed on infected animals were examined, and living 

 trypanosomes were easily found in the intestines of all of them. By 

 the following day these had disappeared. The presence of these 

 living trypanosomes proves that the salivary juice of Stomoxys is
