I refer a specimen without abdomen and with badly tattered wings 

 to this species. It was taken at Matadi, June 20, 1909. It is singula)- 

 that this specimen should bo the only representative of this great genus, 

 which has its metropohs in Africa and which should be represented by a 

 number of species in the eastern parts of the region visited by the ex- 

 pedition, the land of the "White Rhinoceros." It is absent from the 

 densely wooded jungles of the great river- valleys, but appears in the 

 grass-lands, wherever they occur south of the Sahara.

This genus, owing to the seasonal and local variations which occur 

 in every species, presents many puzzling problems, some of which still 

 await satisfactory solution. A multitude of .so-called species, some of 

 which are of doubtful validity, have been erected upon shght but ap- 

 parently more or less constant differences. The test of breeding will 

 alone serve to decide finally what is the exact relationship of some of the 

 forms. The writer has had in his hands at various times, and still 

 possesses, vast numbers of specimens representing the various forms 

 occurring in Africa, but within certain limits has been hitherto unable 

 to satisfy himself as to the proper classification of some of the varieties. 

 The species appear to run into each other, and to be subject to great 

 variation }K)th in size, coloi-ation, and markings. The following accoimt 

 of the specimens brought home by the American Museum Congo 

 Expedition represents the results of very careful study and comparison 

 with other specimens, many of which had })een originally determined 

 by direct comparison with the types in European collections, but nevei- 

 theless it leaves something to be desired, especially in the case of T. 

 senegalensis and its varieties, which is extremely variable.
