274 NOVITATKS ZOOt.OGICAE XXI. 1(114. 



The sjiecies is named in honour of the senior collector, who is to be congratu- 

 lated on obtaining so interesting a novelty. 



Dr. Villenenve, who was good enough to examine the Tachinidae brought back 

 by Dr. Hartert from the Algerian Sahara, wrote to the anthor as follows, under date 

 March 23, 1914, with reference to the species described above: ''A very curious 

 species, which I have never seen before. I regard it as a Calliphorine of the grou]> 

 Rbynchomyiinae {rameau basnl aiitcrieur ciliated), allied to the group Trixa Br. 

 and v. Berg., by reason of its antennae and epistoma, and also allied to the Oestridae 

 owing to its mouth-parts (proboscis and palpi) ; these are greatly reduced in the 3 , 

 but e.\-hibit less reduction in the ? (palpi short, club-shaped). The fly therefore 

 represents a new species and new genus of the ' Oestridae dubiosae ' of Brauer and 

 von Bergenstamm, and is the first Calliphorine lielonging to this group which has 

 come under my notice."
