lobes prominent and a very deep notch between them; apical Joint 

 of maxillary palpi elongate and truncate at the apex, inner edge of 

 mandibles tbin and recurved, mentum witb the sides longitudinally 

 elevated, so tbat it appears to be broadly and deeply depressed along the 

 middle. Clypeus ratber strongly emarginate, head coarsely and densely 

 punctured except tbe vertex, whicb is nearly smootb. Thorax short, 

 lateral margins much serrated, tbe bind angles very obtuse, tbe sur- 

 face rugose. Scutellum closely punctured. Elytra of a dull, reddish 

 colour , with a somewhat silky reflection , each with three elevated 

 lines of whicb the internal ones are broad , tbere is also a fourth 

 line parallel with the lateral margin, the Spaces between these lines 

 are rather coarsely punctured. Pygidium ratber closely and coarsely 

 punctured. Metasternum and bind coxae witb a fine yellowisb pube- 

 scence: bindbody smooth and shining, rather finely and sparingly 

 punctured. Prosternal process erect and very distinct, dilated towards 

 the apex, front femora with an acute angular projection close to the 

 prosternal process. 



Lachnosterna lineata (n. sp.): Rufescens , elytris dilutioribus ; 

 antennis 8-articulatis ; capite thoraceque fortiter crebre punctatis , hoc 

 lateribus crenulatis; elytris sat nitidis, minus fortiter punctatis, lineis

Sarawak. 



Clypeus very short, rounded , only slightly emarginate in the 

 middle. Head rather coarsely and distinctly but not at all rugosely 

 punctured. Thorax not serrate at the sides, but tbe lateral margins 

 with numerous interruptions so as to be crenulate , tbe surface un- 

 evenly covered with rather coarse punctures , the intervals between 

 which in many places are very wide. Pygidium moderately coarsely 

 but not deeply punctured. Prosternal process slender and erect, 

 acuminate at the apex. 



This species is structurally closely allied to L. princeps , but 

 is readily distinguisbed by the sculpture of the head and tborax ; 

 and when the two species are examined other minor differences are 

 seen which cannot easily be conveyed by description. These two 

 very remarkable species form a distinct group in the genus , cha- 

 racterized by the 8-jointed antennae.
