9. Nanacarus Oudms. , nov. gen. 



(With Piale % flg. 23—28). 



Under the name of Hi/popiis minutus , nov. sp., I described a 

 nymphd in the Tijdschrift der Nederlandsche Dierkundige Vereeni- 

 ging , ser. 2, v. 7, p. 85, Two specimens were under my observation ; 

 one was caught by Prof. Dr. K. Knuth on Xi/locopa {Koptorthosonia) 

 tenuiscapa Westw, , the other by Mr. S. A. Poppe on Veftperugo 

 serotinus (Schreb.) 



In a tube with parasites , collected by Mr. S. A. Poppe on Sorex 

 vulgaris L. at Vegesack near Bremen, I found a male and two 

 females of the same species. Thier characteristics induce me to 

 place the animal in a new genus, related io Hericia Can. It differs 

 from this genus specially in the presence of a demarcation between 

 thorax and abdomen. 



I have called the new genus Nanacarus referring to the extreme 

 minuteness of the species. 



10. Glycyborus Oudms., nov gen. 



For the species Gli/cypJiagus plumlger C. L. Kocix^palmlfer Fnva. 

 et Rob., canestrinii Arman. ; and liierophorus Beri., which are 

 distinguished from Gl. intennedìus Can., peregrmans Beri., ornaius 

 Kram., spluipes C. L. Koch and domesticus de Geer, by having a 

 distinct demarcation between céphalothorax and abdomen and jiai 

 feather-like hairs, whilst the others lack these characters, I propose 

 to create a new genus: Glycyborus; ßoqoc = ifiàyog — eater. I take 

 Gl. plumigßr C. L. Koch as the type of the genus. 



11. Genus Nodipalpus Karpelles. 



Wenn we read attentively what Karpelles (Math, u, Nalurw. 

 Bericht, aus Ungarn, XI, 129) tells us of his Genus Nodipalpus 

 and of bis Nodipalpus uhm nov. sp., and when we compare care- 

 fully his drawing of this species with those which Michael presents 

 us of the species of Eistlostoma (= Ametics Duj.), we must un- 

 voluntarily come to the conclusion that Nodipalpus — Aiweius , 

 and that we must adopt the species Anoetus ulmi Karpelles.
