Till' i)ubescence of the upperside is uniformly dayish grey. The pronotum 

 Ijears a white spot in the centre and three whitish obsolescent spots at the sides. 

 Tlie three black lines jirescnt on the jjronotnm of M. a. assimilis and samatrnmis 

 are only indicated at the base and ape.x, the median one being altogether absent in 

 the ? before me. The dorsal carina is feebly ungulate in the centre, the ape.\ 

 of the angle pointing frontad. The elytra are much more sparsely spotted than in 

 sumatranus ; the third interspace bears three white spots and four or five black 

 ones, the largest white spot lieingantemedian and the largest black one median ; the 

 fifth interspace has tlirei' or four white spots and as many smaller black ones ; and 

 the lateral margin has the same number of spots, the white subiuedian lateral one 

 being the largest of them. The uuderside bears white lateral spots as in sumatranus, 

 but the pubescence is not bright ochreous at the sides, as it is in that subspecies. 



s. Mecocerus simulator Pasc. (I860). 



Elytra with tubercle in the third interspace at the beginning of the apical 

 declivity. Sometimes the tubercle is vestigial, but even in that case the third 

 interspace is much broader in that ])lace than the fourth. 



There are two forms of this species in Borneo : true simulator resembling 

 M. wallacei Pasc. (1800), and the other form closely agreeing in colour with 

 M. ga.:ella brunnescens ioxd. {\!^\)X). This second form is the only one we. have 

 from the Kina-Balu; but it also occurs at Lawas and in Brunei, whereas from 

 Kuching, Dutch Borneo, and the Malay Peninsula we have only true simulator. 

 1 name this form 



f. imitator nov. (type : Kina-Balu). 



The pubescence on the liead and rostrum off. imitator is usually ochreous ; the 

 central stripe on the occiput widens more strongly than in i. simnlutor ; the light 

 puliescence of the pronotum occupies about as much space as the dark pubescence, 

 and the markings are very dittuse. The elytra are almost uniformly coloured from 

 base to apex, being greyish clay or dayish grey, with the alternate interspaces
