 Mr. Dohertv, who so greatly enriched our knowledge of the 

 Malayan fatma.

Hab. Island of Nias [Thomas), my collection. 



Tliis species is quite distinet from similarly coloured 

 species deseribed from the same island, notably L. Gestroi Jac. 

 and L. coromandeliana Fab. The differences are to be found 

 in the head, which is not constricted behind, in the nearly 

 quadi-ate and impunctate thorax and in the colour of the under- 

 side and legs, the punetuation of the elytra also is much stronger 

 than in L. Gestroi and their coloration is not black, but blue; 

 in the variety the abdomen is black, but other differences I 

 cannot find.
