54 Mr. G. Lewis ou 



sutuial stria incurved at either end, pygidia closely and 

 nnukedly sculptured, prosternum compressed, mesosternuni 

 truncate and niarginate, tarsal groove straight, tibite 3-dentate, 

 terminal tooth very robust. 



Type I lifter cetieus, Lewis. 



The sj^ecies for which this genus is established have 

 hitherto been included in Ilis(er,o\' which the type is //. unt- 

 color, L., 1735 ; the species are ofer, Payk., aneuSjafricanus, 

 angonieusis, creindatus, marshaUi, nyasscB, similis, and zam- 

 hesiiis, Lew. The last sj)ecies was formerly assigned to 

 Zahromorphiis. The antennal fossettes in zinicolor are wide, 

 open, and shallow. The species I have jilaced in Exorhahdus 

 differ considerably also in their general facies and are natives 

 of middle Africa. Ilistei' scabrijyi/gtis, Sell., is described as 

 having the subhumeral stria complete, but I have not seen 

 the species. Schmidt describes Hister ohtusisternus and 

 mechowi as having the inner subhumeral stria complete, but 

 this is not correct, anteriorly in both species it gives place to 

 the fine oblique stria very generally seen in the Histeridse. 



Hister belli, Lewis, 1904. 



There is an example of this species in the British Museum 

 from Berhampur, India, which measures over 11 mm. The 

 type specimen measures 9^ mm. 



Hister simulator, sp. n. 



Oblongo-ovatus, parum convcxus, niger, nitidus ; fronts stria 

 semicirculari Integra, mandibulis hand caiialiculatis ; prouoto 

 stria interna integra, externa paulo breviore ; elytris stria sub- 

 humerali nulla, 1-4 dorsalibus integris, 5 ante et suturali in 

 medio abbreviatis ; propygidio parum grosse hand dense punctate ; 

 pj-gidio similiter punctate sed apice laivi ; mesosterno emarginato, 

 stria in medio interrupta ; tibiis anticis 3-dentatis. 



I. 6-8 mm. 



The facies of the above is extremely similar to hottentotta, 

 Er., and others of the same group, but it differs by the frontal 

 stria being almost semicircular, by there being no humeial 

 sulcus or stria, and by the larger punctures, not very closely 

 set, of the pygidia. The mesosternum is rather deeply 

 emarginate and the marginal stria does not pass the 

 eniargination. 



Hah. Senegal. Four examples. 



Hister guinensis, Payk. 

 I have an example from Ashanti which corresponds exactly
