Of this great and truly northern genus, the two species 

 described below are, I believe, the first from the south of 

 the tropic of Cancer that have been published. They are 

 true Lepturoi, and in colouration generally and habit they 

 approach L. l2-guttata, Fabr. Mr. Wallace seems to 

 have found only a single individual of each species. Mr, 

 Lamb has found a single imperfect specimen of a third 

 species at Penang. 



Leptura histrionica. 



L. nigra; elytris linea humerali curvata, fasciisque 

 duabus flavis, ornatis : antennis articulis 8 (basi ex- 

 cepta) 9 et 10 albis; femoribus concoloribus.
