in hispidus. Spines on cephalo-thorax equally long, but less rigid than 

 in hispidus, giving in general a less thorny character to the new species.

54. Leander northropi n. sp. (PI. xxx, Fig. 4) 



(a) 1 specimen. Nassau, N.P., Jan., 1890. 



A single specimen with a total length of 30 mm. Length of cephalo- 

 thorax to tip of rostrum 11.5 mm. 



Cephalo-thorax with small tooth below orbit and a very minute tooth 

 below this and a little back from the anterior margin on the lateral 

 surface. 



Length of rostrum to posterior end of orbit 7 mm., slightly curved 

 upwards toward apex. Ten teeth above, four below ; the first dorsal 

 tooth forms with the tip of rostrum a bifid extremity. A long interval 

 between first and second tooth ; interval between second and third one- 

 third the length of that between first and second; fourth, fifth, and sixth 

 teeth follow at slightly diminishing intervals, the sixth being over the 

 posterior part of orbit of eye. Seventh, eighth, and ninth teeth close 

 together, posterior to orbit of eye. 



The first ventral tooth is a little in front of second dorsal, second 

 ventral below second dorsal; third and fourth at equal intervals be- 

 tween second ventral and orbit of eye. 



Inner antennas : peduncle reaches beyond second ventral tooth of 

 rostrum ; proximal segment about equal to the two distal. Upper flagel-
