Tbis s[)ecies recorded from N. Borneo by Dr. Forster appears tc 

 me to be very closely related to tbat immediately preceding it, 

 I have not seen examples of either of these two last species.

The females each bave four large spines on ventral plate, tbe 

 median pair being larger than the lateral pair. Tbe apex of tbe 

 plate is strongly decurved, and the niargin carries sujaller spines 

 on either side of the four larger ones. From the description and 

 figures (Martin, loc. cit. figs. 163, 166) I cannot separate tbis 

 species from the next.
