Fam. Mimetidae. 

 Gnolus Simon. 



Simon, Ann. Soc. ent. Belg. C. R. 1879, p. LVIII. 



This genus was constituted by Mr Simon 1879 1. c. and 

 counts for the present a little more than half a dozen species 

 all found i South America. As the type for the genus he 

 regards Arkys cordiformis Nic. With this species he even 

 unites as sure species Arkys spiculator Nic. and limbatus 

 Nic. In some låter papers (Ann. Soc. Ent. Fr. 1893 and Act. 

 Soc. Se. du Chile 1896) the same arachnologist has described 

 two species from Brazil and one — the most remarkable — 

 Gnolus angulifrons Sim. from Chile. By these three species 

 the limitation of this genus has in an essential degree been 

 extended. In the collection of Mr Dusen are the following 

 species: Gr. spiculator (Nic), cordiformis (Nic), angulifrons 

 Sim. and two new species Gr. affinis and zonulatus, the first 

 nealy related to G. spiculator (Nic), the second very nearly 

 to G. angulifrons Sim, 



Concerning the systematic state and generic relations of 

 the genus Gnolus Mr Simon has pronounced two different 

 opinions. In his paper Note sur Jes Epeiridcc de la sous- 

 famille des Ärcyince (Ann. Soc. ent. Belg. 1879) he has in one 

 group Arcyintfi united the genus Arcys Walck., Gnolus Sim. 

 and Oarces Sim. In the second edition of Histoire Natureile 

 des Araignées T. I, fasc. 4 he has changed his opinion and 

 refers the genus Oarces to Mimetidse and forms for the other 

 two genus two different groups Arcyese and Gnolese, and re- 

 tains them in the family Argiopidtfi.
