The report is based mainly on a large collection of mosquitos 

 from Onderstepoort. Three new sjDecies are recorded, viz., 

 Psevdohowardina lineata, Grahhamia cahalJa and Uranotaema 

 niviiwiis; also two new varieties, one of Cule.v salish'urieyisis and 

 the other of Cule.v thcileri. Three species previously unrecorded 

 iu the Transvaal occur in the collection, Cule.v cuinniin.^ii, C. 

 guiarti and Chrysoconojis fusco2:)ennatus. The insect previously 

 recorded by the author as Taeniorhynchus tenax var. macidipes 

 is undoubtedly the same as Cule.v quasigelidus, Tlieo. The 

 generic name Mansonia used in the previous report has to sink 

 as a synonym of Taeniorhynch'us, Arr., and the author proposes 

 the name P.'<eudotaeniorhynchvs for the species which he has 

 previously called Taeniorhynchus. The author criticises various 

 chano-es in nomenclature suggested by Mr. F. "VV. Edwards.

The members of the Katanga Scientific Mission have previously 

 (Bull. Soc. Pathol, exotique, iv, 1912, p. 528) described some 

 trypanosomes from the intestines of an Asilid and of two 

 Eeduviids, which latter have since been identified by Schouteden 

 as belonging to the same species BJiinocori.'? albopilo.nis. Sign. 

 In the present paper the results are amplified and illustrations of 

 the parasites given, the authors using Jjcptomonas as a term 

 synonymous with TIerpetomonas of British investigators. The 

 method by which 'Asilus are infected is not yet clearly understood. 

 These voracious Diptera prey upon other insects which they catch 

 on the wing, and in spite of feeding them in the laboratory on 

 Pycnosonia, Sarcophaga and Gloi<.iina, no trypanosomes developed 

 in the intestine of the Asilids. The question of Keduviids being- 

 infested by trypanosomes assumed great importance since Chagas 

 showed that the fiagellates found in the intestine of Conorrhinus 

 viegistus were a stage in the cycle of a pathogenic trypanosome ; 

 and, more recently Lafont discovered tliat the parasites of 

 Conorrhinvs rubrofasciatus were capable of infecting the rat. 

 In the course of their investigations the members of the Katanga 

 Mission were Tinable to find blood-sucking Eeduviids, altluiugh 

 their attention had been directed towards these insects ; but they
