NOTES ON THE ETHIOPIAN FRUIT-FLIES OF THE FAMILY 

 TRYPANEIDAE, OTHER THAN DACUS (S.L.), WITH DESCRIP- 

 TIONS OF NEW GENERA AND SPECIES (DIPT.).— I.

(Plate V.) 



While the Oriental* and Neotropicalf Trypaneids have been the subject in 

 recent times of extensive studies, those of the Ethiopian Region are still almost 

 in the same condition in which they were left by H. Loew in his valuable paper of 

 1861. % Only more recently Prof. Hendel has made an attempt to erect some 

 Ethiopian genera in his general classification of the family§ ; but all these genera 

 are only shortly characterised by means of dichotomic tables, and most of their 

 type- species have been given names as new species, but without any description. 



The object of this paper is to give a summary account of our present knowledge 

 of the classification and distinctions of the Ethiopian species of Trypaneidae, 

 with the purpose of facilitating further research in this very important family 

 of flies. 



The main material was submitted to the writer by the Imperial Bureau of 

 Entomology, through the kindness of Dr. Guy A. K. Marshall, and is now to be found 

 in the British Museum ; while some of it has been accumulating from various 

 sources and for many years in the private collection of the writer himself. 



I have already given in 1908|| a catalogue of the Ethiopian Trypaneids 

 described up to that time, with the enumeration of about 70 species (not counting 

 Dacus) ; a considerable number of additional forms have however been 

 subsequently described by Austen, Enderlein, Graham, Hendel, Lamb, Silvestri, 

 Speiser and myself, thus bringing the total number of the known species to about 

 110 (always excluding Dacus). No doubt this number may be somewhat reduced 

 by synonymy, but it is certainly much lower than that of the actually existing 

 species ; for in the Oriental and Australian Regions about 170 species (without 

 Dacus) are known, and in the Neotropical, including Mexico and Central America 

 (a region in which Dacus does not occur) about 250. 



According to the classification proposed by me,^f and accepted with slight 

 modification by Prof. Hendel, the family may be divided into three subfamilies 

 the Dacinae, the Ceratitinae and the Trypaneinae (Tephritinae), to which
