Subfamily BARYCHELIN.E. 



Genus Idiommata, Auss. 



In 1888, 3 Simon proposed Encyocrypta as a genus of this sub- 

 family, his type being E. meleagris, Sim., a New Caledonian 

 species, but in 1892 4 he sank it as a synonym of Idiommata. In 

 1895 Pocock, in examining a male of I. blackwalli, O. P. Cambr., 

 discovered that it possessed a Wood-Mason's stridulating organ 

 which no species of Encyocrypta has. For the reason herein 

 stated, he re-characterised Encyocrypta, and in 1901, Hogg, 5 in his 

 "Australian and New Zealand Spiders of the suborder Mygalo- 

 morphaz" catalogues both genera as branches of our fauna, until, 

 at any rate, more specimens (males and females) shall have been 

 examined to see how far they agree respectively with those of /. 

 blackwalli, 0. P. Cambr. In so far as the two genera under 

 discussion are concerned, I follow Pocock and Hogg.
