new Species of Histeridje. 99 



that there is a short oblique humeral stria, but this oblique 

 stria, very common throughout this family, is not usually 

 called a " humeral " stria — humeral striae, as usually under- 

 stood, are longitudinal. 



Hah. Mikindani, E. Africa [Raffray). 



CORNILLUS, gen. nov. 



Body oval or oblong-oval ; forehead impressed longitu- 

 dinally, stria biarcuate ; thorax, antennal fossa in the anterior 

 angle; elytra, strise fine, crenate, or punctiform ; pio- 

 pygidium finely and evenly punctured, binodulosc ; pro- 

 sternum bistriate ; anterior tibite 4:-dentate. 



This genus has much general similarity to Omalodes ; the 

 species to be included in it are tuherculipygus^ Sch., buUatusj 

 tuherculatuSy and tuberosus. Lew. 



CONTIPUS, Marseul, Mon. p. 548 (1853). 



I propose to include in this genus G.flexuosus, Sch., as the 

 type, because it is the commonest species existing in collec- 

 tions, and digitatuSj Mars., with immaryinatus and oMongus, 

 Lew, For the present I would also include the American 

 species, abhorrens, Sch., platanus and suhquadratus, Mars. 

 The African species with didymous elytral stria I assign to 

 the new genus below. 



EUGRAMMICUS, gen. nov. 



Body oval, more or less convex ; head transverse, man- 

 dibles equal and strongly dentate, labrum short and transverse, 

 frontal stria3 complete ; thorax with two lateral strife ; an- 

 tennal fossfB are open from below and shallow and somewhat 

 similar to those of Contiinis ; elytra, stria3 are wide and 

 shallow, with fine crenate edges (Marseul termed them didy- 

 mous), stripe 1-4 complete, 5 and sutural nearly complete, 

 sutural turning outward before the base ; pygidia almost 

 impunctate ; mesosternum feebly sinuous anteriorly ; tibia; 

 dilated, anterior strongly 3-dentate. Other characters similar 

 to those of Coniipus. 



Type, Contijtus didymostrius, Mars. 



The other known species are sinuosus (convex), proximus, 

 and fractistrius, Lew. (less convex) ; at present only unique 

 examples are in collections, so that it is highly probable 

 the species have secretive and peculiar habits.
