There are specimens of both sexes from both Liangagas and 

 Soekaranda. 



2. Lacertobelus longimanus, n. sp. 



L. dentipedi affìnis at major, rufo-piceus, nifidus el y tris uigro- 

 viridibus vel caeruleis, antennis nigris articulo basalt ruf'o, pedibus 

 piceis, basi rnfis. — Long. 8-10 millim. <?. 9. 



Mas, pedibus anticis perlongis, femoribus tenuibus hand vel vix 

 dentato, luberculo parvo tantum inlus prebenlibus, epistomate antice 

 producto, quasi rostrato. 



flab. Sumatra (Wallace) ; Soekaranda (Dohrn) ; I. Mentawei, 

 Si-Oban, Sipora (Modigliani); S. E. Borneo, Martapura (Doherty). 



This species appears to be distinct from L. dentipes by the 

 fact that although some male specimens are larger and well 

 developed, the femora are not toothed, but only exhibit a line 

 sinuation with a slight tubercular elevation at the same place 

 as the acute tooth in L. dentipes, indeed I cannot in all males 

 even see this. The front legs are very long indeed, as long or 

 longer than the body. The head and thorax are rufo-piceous, 

 nearly smooth in some, more thickly and distinctly punctured 

 in others. 



The epistoma is produced as in L. dentipes, the thorax is of 

 the same form, and very convex (in the male), but in the small 

 example from Borneo, it is much more distinctly and deeply 

 punctured, and this example is only six millimetres long, and 

 possibly represents a distinct species. The elytra are almost 

 precisely as in L. dentipes, but their bluer colour, which is 

 correlated with the more rufous head and thorax , is possibly 

 due to less maturity. The darker examples from Sumatra how- 

 ever have the head and thorax rufo-piceous.
