sides of the body. The second specimen, a paratype, has two 

 such bristles. Fig. 8 represents the seventh sternite and eighth 

 segment of this example, whereas the figure of the receptaculum 

 seminis (fig. 7) is taken from the type. 



The bristles on the second segment of the antenna are shorter 

 than one-third the length of the club. 



The proportional width (measured near the base) and length 

 of the stylet are 1 : 3.3. 



Kirkenen, Finmark ; the host not known. 



The species apparently also occurs in France, whence we 

 have a female found at S. Paul, Basses Alpes, on Evotomys nageri 

 by Monsieur A. Mottaz. The example was originally identified 

 by us as sibirica, Wagn. (1898), but it agrees so well with 

 thoracicus, particularly the paratype, that we must consider it to 

 belong to that species. The male may possibly be different.

Both sexes are known. 



Wagner (1912) pointed out some differences between his 

 sibirica of 1900 and dcea. 



The lateral bristles of the eighth tergite of the female are very 

 numerous, according to Dampf's figure. The movable process of 

 the clasper of the male is elongate-triangular, being widest at 

 the apex and having two black spiniform bristles. One of these 

 bristles is pointed and placed below the middle of the posterior 

 margin ; the other spine is short and obtuse, and is situated at 

 the posterior apical angle.

 says in 1912, I. c).
