Prosternum (<?) impressioiie profuiula, in (c^) minore plicatura loiigitudinali in 

 partes duas divisa, dual)us spinis longis gnu'ilibus instructuui, (?) transverse leviler 

 bisnlcatum. 



Long. 13 mm., rostr. 4, elytr. 9, lat. 6^. 



The dorso-lateral keels of the rostrum are well marked; the_v approach each 

 other so slightly between the antennae that, when seen from above, they almost 

 appear to lie parallel. The median sulcus of the front of the head and base of the 

 rostrum is deeper than in all the other species of jl/ecoc«nt8, and runs a little way 

 along each side of the median carina of the rostrum ; this carina is rather high, and 

 reaches from the basal fourth of the rostrum to between the antennae. 



Hoh. Barram R., X. Borneo, and JIalacca. 



Differs from M. (jftsella, to which it is similar in colour, especially in the 

 granulose pronotum and short elytra. 



13. Mecocerus simulator Pasc. 



This species will be at once recognised by a small tubercle on each elytron 

 standing on the third interstice just at the beginning of the ajjical declivous part. 

 The examples in Pascoe's Collection resemble in colour and pattern the Mecocerus 

 wallacei Pasc. — i.e. the base of the elytra is more or less ashy grey, and somewhat 

 spotted with grev, while the rest of the elytra is more or less brown, bearing a few 

 grevish .spots only. Three specimens in the Tring ^Museum from the Barram Uiver, 

 X. Borneo, and one from the Kina Balu, are similar in coloration to M. gazella ab. 

 brimnescens ab. nov.
