new genera and .species of Tenehriunlda;, ^^c. 295 



angled at the sides at their junction Avith the epistoma ; 

 this latter having the front angles toothed (or tubercled), 

 and strongly emarginate between ; underside less opaque ; 

 and the prosternal process smoother. 

 Long. 51 lin. 



Tetrapltyllus Fairmairii, n. sp. 



Smaller and more oblong-ovate than formosns ; the 

 sides of the elytra more gradually rounded from the basal 

 angle, more dilated posteriorly ; the convexity on the back 

 extending nearer to the apex ; the elytra are consequently 

 more abruptly declivous behind ; the strias much more 

 deeply impressed, the fourth and fifth uniting much 

 nearer the apex ; the intervals more convex and finely 

 but distinctly punctured; underside more nitid; prosternal 

 process more sharply tapered behind, the sides completely 

 sulcated near the margin, an oblong depression between 

 the coxa?. 



Long. 51 lin. 



The elytra more swollen behind will also serve to 

 distinguish this species from acerhus, Coq. 



Tetraphyllus tuber culijiennis, n. sp. 



Very distinct from any of the described species by the 

 elytra gently and regularly convexj the intervals termi- 

 nating apically in oblong tubercles. 



Head and prothorax dull black ; epistoma scarcely 

 emarginate in front, the suture arched and plainly im- 

 pressed ; frontal furrow not extending beyond the epis- 

 tomal suture ; head very finely and remotely punctured ; 

 prothorax ample, but little convex, finely and not closely 

 punctured, very deeply arcuately emarginate in front ; 

 front angles not acute ; base very feebly bisinuate ; sides 

 rather strongly curvedly contracted anteriorly, very feebly 

 narrowed at the base ; scutellum shining black ; elytra 

 broadly oval, regularly and not at all strongly convex, 

 gradually declivous behind ; sides regularly and gently 

 rounded from the basal angle to near the apex ; finely 

 and cleanly striated, the stri:i3 uniting by pairs at the 

 base ; five and six abbreviated and terminating at the 

 intrahumeral depression ; posteriorly the first stri;e ex- 

 tends to the apex, two and three are united higher up, 

 whilst four and five, six and seven, eight and nine unite
