Harpegnathos saltator, Jerdon, Madr. Journ. Lit. Sf Sci. (1851) 

 116; Ann. S)- Mag. Nat. Hist. 2nd ser. xiii. 100. 



" Wouker : head long and granulated ; jaws with a strong tooth 

 near the base pointing downwards and inwards, and thence gra- 

 dually tapering to the tip, and finely serrated, |^of an inch long; 

 thorax barely grooved ; abdominal pedicle small, low, ovate ; 

 abdomen very long ; sting large ; head and abdomen blackish- 

 brown ; thorax and legs rufous. Length | of an inch. 



" I have given it the name of saltator from its power of making

 Its society does not consist of many individuals. It appears to 

 feed on insects, which it seizes alive." — {Jerdon.)

Mr. J. C. Bowring informs me that this species has the power 

 of making surprising leaps, — a fact also mentioned by Jerdon in 

 his description of the Indian species. 



3. Drepanognathus venator. B.M.

 entatus, but with the head, thorax and abdomen black; the
