Three adult specimens (2 (ƒ and 1 9) from Tahiti and 

 two very young males the locality of which is unknown. 



The two young males certainly belong to Trap, latifrons 

 A. Milne Edw. and agree completely with the description 

 and the figure of that species. They diSer from the three 

 adult individuals almost only by having the areolae of 

 the reticulate pattern on the cephalothorax larger and 

 less numerous. This species may be distinguished at first 

 sight from Trap, areolata Dana: 1° by the general shape 

 of the cephalothorax , 2° by the granulate lower margin 

 of the hands , and 3° by the areolae. In Trap, areolata 

 Dana the areolae are much smaller and much more nume- 

 rous and do not exist on the ambulatory legs. The lateral 

 teeth of the cephalothorax are less sharp in the adult than 

 in the young, and this is also the case with the acute 

 tooth at the internal angle of the wrist of the anterior 

 legs. In adult specimens the upper-, as well as the lower 

 surface of the cephalothorax is marked with a net of 

 areolae , which are a little larger than those of Trap, areolata ; 

 these areolae are also seen on both sides of the anterior 

 legs. Spot-like red transverse bands exist on the ambulatory 

 legs, two or three on the meropodites, and one on the 

 carpo- and propodites. 



I finally may observe that this species differs from Trap, 

 rufopunctata Herbst exclusively by the pattern , 

 showing in any other respect the most complete resemblance 

 with it. 



The largest specimen, a female, has the following 

 dimensions:
