A species of this iuteresting genus is represented in the 

 colleotion bv three young speoimons. I have not been able 

 to State the sexe witli eertainty. as the genital organs not 

 are so fullgro\\n. that it is possible to do it. The tarsus is 

 verv large as by young males. but it is furnished at the 

 apex with a single claw with some long denticles. a charac- 

 teristic that is - as far as I know - distinctive only for 

 the female. Among the known species there is none that is 

 concerning the plates on the dorsal scale satisfaetory descri- 

 bed and none of the published figures agree perfectly with 

 my specimens. 



If my species is new for the science. I propose the na me: 



H. erueiata n. sp. (Pl. o. fig. 13».

 larger. about their diameter apart and the distance from 

 laterals verv long. Area of central eyes a little narrower in
