Oriental Apliodiid Coleoptera. 537 



Archipelago) in the east to ^lauritius in ihe west, and T liave 

 even seen (in M. Rene Obcrthiir's colhction) a species from 

 West Africa. Tlie only mainland species yet recorded is 

 R. hirmanicus, Fairm. ; but R. sumatrensi's, Fairm., was 

 found by Doherty at Perak, and I describe here another form 

 occurring in the same locality. 



Bhyparus peninsularis, sp. n. 



Niger, opacas, griseo-indutus, modice elongatus ; capite lato, 6- 

 cristato ; prothorace antice valde dilatato, angulis rotundatis, 

 lateribus medio sat dilatatis, deinde contractis, angulis posticis 

 obtusis, disco 6-carinato, carinis duobus internis leviter sinuatis, 

 medio paulo approximatis, duobus intermediis late iuterruptis, 

 exteruis iutegris, intervallis medio at externis sparse grosse 

 punctatis, intermediis laevibus ; elytris acute costatis, costis 

 suturalibus paulo latioribus, postice regulariter arcuatis, discoid- 

 alibus postice abbreviatis, valde incrassatis, callis apicalibus 

 prominentissimis, intervallis grosse biseriatim punctatis, lateribus 

 baud parallelis, postice distincte contractis ; pygidio longitudin- 

 aliter carinato ; corpore subtus sat crebre punctato ; tibiis quatuor 

 anterioribus apice valde incurvatis, femoribus intermediis subtus 

 bidentatis. 



Long. 6-7 mm. 



ITah. Malay Peninsula, Penang (Lamb), Perak {Do- 



herti/) . 



1 have seen three specimens, of which that from Perak is 

 in M. Oberthiir^s collection. 



The species resembles R. Saundersi, Pascoe, and still more 

 another Bornean form which I have seen identified by 

 M. Fairmaire as his R. approximans, but which more nearly 

 agrees with the description of R. dentlcollis, and may be 

 distinct from both. R. peninsularis is rather larger than 

 either and relatively broader, with its elytra tapering more 

 behind. It differs most obviously iu its punctnration, the 

 inner lateral interstices of the pronotum being smooth and 

 the middle and outer interstices thinly strewn with large 

 punctures, whereas the other species named have the pronotum 

 evenly and densely punctured. The punctures upon the 

 elytral interstices are also very large and arranged in not 

 closely serried rows. The elytra are not angulated behind 

 at the suture, as in R. Saundersi. R. sumatrensis, Fairm., is 

 also a nearly related form, but it is still larger and the pro- 

 notum is almost entirely im punctate.
