crebre elevato-tuberculatis, iitrisque tuberculis sex magnis

Long. 2| lin. 



Hab. Sarawak, Borneo. 



Closely resembling the last species, much smaller, the larger 

 tubercles on the surface of the elytra being as broad, or even 

 broader, at their base, but much less strongly elevated; the second 

 and third are also rather differently placed on the surface, the 

 first of them being halfway between the humeral callus and the 

 suture, and the other close to the suture itself; the fifth and 

 sixth have their apices rounded and not conical ; the seventh large 

 tubercle is absent. The elytra are closely covered with small 

 tuberosities, to the almost entire exclusion of the puncturing ; 

 those near the hinder half of the lateral margin are larger and 

 more distinct than those elsewhere and form a row of rounded 

 protuberances. Head very similar to that of I;, monstrosa, the an- 

 tennae somewhat sliorter. Thorax finely but subremotely punc- 

 tured ; centre of disc convex, sliglitly gibbous, longitudinal sulci 

 obsolete in front of the transverse groove, being visible only at 

 the base in the form of two oblique impressions. 



18. Lerna constricta,n. sp. 



Elongata, parallela, subcylindrica, rufo-testacea, nitida; an- 

 tennis (basi excepta) nigro-piceis; thorace cylindrico, lateri- 

 bus valde et late constricto, supra pone medium fortiter 

 transversim sulcato, tenuiter sed sparse punctato ; elytris 

 violaceis, infra basin late transversim depressis, fortiter 

 punctato-striatis, striis distlnctis, punctis ante medium mag- 

 nis, profunde impressis, postice minoribus, interspatiis trans- 

 versim rugulosis, pone medium subcostatis ; abdominis seg- 

 mentorum basi et metasterni utrinque plaga pallide piceis.

Hab. Sumatra. Var. A, Penang. 



Head deeply constricted behind the eyes ; face trigonate, fore- 

 head smooth, impressed with a small fovea ; antennae nearly equal 

 in length to the body, slender, filiform, not thickened towards the 

 apex, the second and third joints nearly equal, the fourth and fifth 

 increasing in length, the others each equal to the fifth ; labrum and 

 apex of jaws black, eyes slightly notched. Thorax subquadrate, 

 sides produced in front behind their apex into an indistinct tu-
