Type, E. meleayris. 



This genus was created by M. Simon for a Xew Caledonian 

 member of the group (meleayris), but was subsequently merged 

 by him in the genus Idiommata Auss., from which, under the 

 circumstances above detailed, it was again resuscitated by Mr. 

 Pocock. 



Erom Herr Ausserer's synopsis of species (Verh. k.k. zool.-bot. 

 Ges. Wien, Band xxv. 1875, p. 164) I translate the following: — 



1. Cephalothorax and upper side of abdomen not clothed 



with silver hair 2. 



2. Front middle eyes of second group at least their 



diameter apart ; cephalic fovea deep half-moon 



shape with the opening in front E. fusca L. K. 



Front middle eyes of second group less than their 

 diameter apart ; thoracic fovea straight 3. 



3. Abdomen brownish yellow, with a dark reddish-brown 



network spread on it E. reticulata L. K. 



Abdomen black-brown, with yellowish-brown hairs 

 without any network marking E. aussercri L. K. 



EXCYOCRYPTA RETICULATA L. Koch. 



Encyocrypta reticulata E. I. Pocock (loc. cit.). 



Idiommata reticulata L. Koch, Arachn. Austr. 1874, p. 47. 



From British Museum specimens (three females from Eock- 

 hampton) labelled E. reticulata, I take the following particulars : — 



The colour is chestnut-brown to lighter yellow-brown all over. 

 The abdomen is clothed with thick short brown hair, intermingled 

 with bristles and some spines. The six rear eyes yellow, the two 

 front black. 



A light rastellum of spinous bristles. 8 large teeth on inner 

 mai'gin of falx-sheath ; 12 quite small intermediate at lower end ; 

 1 large at lower end of outer edge. Thoracic fovea procurved (?). 



Sternum a broad oval. Of the sternal sigillae the three pos- 

 terior pairs are moderate in size and marginal ; the anterior pair 

 under the lip very large.
