Parona 1895, not mentioned in Das Tierreich, evidentiy is 

 based on hypopi. 



Of the Pterolichinae the genera Pterolkhus, Frej/aiia, Xoloptes, 

 Falculifffv have vertical hairs; so they do not belong to the 

 subfamily of Pteivlicheae, but to the Dermoglyphinae. I was not 

 in the occasion to examine the genus ßdeüori'hync/ius, but on 

 comparing the drawings in my possession, I think Bdellor- 

 rhynolLiis will prove to be provided with vertical hairs. Of the 

 genus Chilocerds drawings are never published and the des- 

 criptions are too vague, but I think they vvill prove to be 

 Dermo(^lyphinae. — Of 'he genus PteroUchus itself an immense 

 mass of species are destitute of vertical hairs. For these species 

 I chose the name of Avemoaria, placed in a subfamily of 

 Avenzoariinae (Entoniologische Berichten no. 21, 1 Januari 

 1905). The type-species of Avenzoaria is PteroUchus totani 

 Can. In fact the habitus of those PteroUchus which are provided 

 with vertical hairs, is that of Thecarthra and Sanmioidca, 

 especially in the legs, and more especially in the females. 



Of the Dermoglyphinae the genus Dermoghjplius is provided 

 with vertical hairs. Mkgnix has not drawn them in the type- 

 species Dermofjbjphus eloirfatus. Yet I am convinced of it, that 

 carefuU examination will prove that they are present, as the 

 very related D. animi Oudms. is provided with them, though 

 minute ones. Of the remaining Dermoglyphinae the genera 

 Thecarthra, Syringohia and Sphaerogastra are provided with 

 vertical hairs. Moreover they have two sabcapital chitinous 

 (interior) tubercles and transparent low crests on the dorsal 

 side of the legs, especially on legs I an ! II. I do not know 

 the genera Anasicydium and Ä'eumannia, but I think they are 

 real Dermoglyphinae and provided with a pair of vertical hairs. 



Of the Analginae the genus Pteronyssus in earlier dates 

 belonged to the PteroUcheae; later it is brought in the Anal- 

 ginae because the legs III of the c^ are thicker than the remaining 

 ones. But we know that this may not be considered as a
