subacute, apical areas wrinkled, and behind middle strongly 

 transversely carinate, the disk somewhat obsoletely centrally 

 carinate, the posterior process strongly tricarinate, its apex 

 slightly passing the posterior angle of the inner tegminal 

 margin.

Hab. Borneo; Sarawak [R. She/ford). 



A small well-marked species, the expanse of its broad 

 lateral pronotal processes almost equalling its longitude 

 including tegmiua. 



Centrotypus taurus, sp. n. 



Pronotum bluish black, apical areas of the lateral pro- 

 cesses purplish black ; face and body beneath thickly, 

 longly, ochraceously pilose; legs castaneous brown, the tarsi 

 more ochraceous ; tegmina very pale ochraceous, the apical 

 area castaneous, the costal margin blackish ; pronotum 

 thickly coarsely punctate, the lateral processes broad, trans- 

 verse, slightly recurved, their apical areas laminate, almost 

 impunctate, wrinkled, their apices anteriorly broadly, 

 obliquely rounded, posteriorly shortly subacute, the disk 

 obsoletely centrally carinate, the posterior process strongly 

 tricarinate, its apex subacute and passing the posterior angle 

 of the inner tegminal margin. 



Long., inch tegm , 8^ mm. ; exp. lat. pronot. process. 

 7 mm. 



Hab. Siamese Malay States {Annandale and Robinson). 



CentroUjpus siametisis, sp. n. 



Head and pronotum bluish black ; body beneath and legs 

 dull black ; tegmina pale ochraceous^ subhyaline, the apical 

 area pale castaneous, the costal area broadly black ; pro- 

 notum thickly punctate, the lateral processes moderately 

 broad and long, transverse, their apices very slightly re- 

 curved, their apical areas very distinctly obliquely impressed, 

 posteriorly transversely carinate, their apices anteriorly 

 rounded, posteriorly broadly subacute, the disk faintly 

 carinate, the posterior process strongly tricarinate, its apex 

 subacute and about reaching the posterior angle of the inner 

 tegminal margin.
