320 Mr. W. L. DIstant's Rhynchotal Notes. 



Periaman wallacei, sp. n. 



Pronotum and legs black ; an arcuate linear spot beneath 

 the lateral pronotal processes^ a large spot on each side of 

 base of posterior process and apices of anterior femora 

 ochraceous ; face and body beneath thickly greyishly pilose ; 

 tegraina pale bronzy subhyaline, base and costal marginal 

 area — extending to apex — black ; pronotum coarsely punc- 

 tate, the disk strongly centrally carinate, the lateral processes 

 moderately well produced, slightly recurved, centrally cari- 

 nate, the anterior and posterior margins broadly sublaminate, 

 their apices subacute ; posterior process robust, strongly 

 tricarinate, moderately laterally compressed, beyond middle 

 strongly narrowed to apex, which is subacute, and reaching 

 the posterior angle of the inner tegminal margin ; femora 

 moderately thickened ; face concavely emarginate before 

 clypeus. 



Long., inch tegm., 8^-9i mm. ; exp. lat. pronot. process. 

 5 mm."^ 



Hab. Borneo ; Sarawak {A. R. Wallace^ Brit. Mus.). 



Otinotoides, gen. nov. 



Allied to Otinotus, Buckt., from which it principally 

 differs by the posterior pronotal process, which is more 

 robust, especially at base, where it has a distinct medial 

 carination on each side ; it touches the scutellum and then 

 is distinctly moderately convexly elevated, its apical half 

 roundly deflected, its apex slender, subacute, and almost 

 reaching the tegminal apex.
