Among the zoological collections brought honie by Dr. E. 

 Lönnberg from the countries bordering on the Caspian Sea, 

 which he visited last spring (1899), there are also some species 

 of Apterygogenea, which were kindly handed över to me by the 

 collector to classify. Owing to the long drought, which prevailed 

 in Southern Russia last spring, the Apterygogenea, which as a 

 rule like moisture, were very rare. Consequently the collection 

 only contains a small number of species. The existence of 

 Collembola in that part of the world not having been, as far as 

 I know, yet reported (anless indeed some record of it might be 

 hidden in the Riissian literature), I have thought it to be of in- 

 terest to publish the following short list, since any addition to 

 our kuowledge about the distribution of these animals, which are 

 from a zoogeographical point of view so peculiar, must be wel- 

 come. And I have taken up my task with all the greater 

 pleasure as one of the species is new to science. This species 

 I take the liberty of naming after the collector.
