and Nov.), Singapore, Bukit Timah {Bryant, May) ; Borneo, 

 Sarawak : Lundii {Bryant, Jan.). 



A considerable series was found by Mr. Bryant at Penano. 

 where the species was also taken by Lamb many years 

 ago. 



The shape is peculiar. Excluding M. teslacea, which 

 does not belong to the germs, it is the most elongate species 

 known to me. Its widest part is considerably behind the 

 middle of the elytra and the ])ronotum at its widest part 

 is narrower than the elytra at the shoulders. It is very 

 smooth and shining above, except at the sides of the 

 pronotum, which are rugulose and thinly clothed with very 

 minute grey setae, the entire upper surface bearing similar 

 but scattered and extremely minute setae, and the head, 

 legs and lower surface rather closely clothed with very 

 short hair. The antennae are rather long but closely 

 articulated and widening gradually from the third joint, 

 the three joints forming the club being little differentiated 

 from the rest. 



The female is almost similar to the male, but the antennae 

 are a little shorter and all the tibiae rather more slender.

Hah. Borneo, W. Sarawak : Mt. Matang {G. E. Bryant, 

 Dec, Feb.). 



Mr. Bryant found one specimen of each sex. 



This species is very similar to M. brevicollis Gorh., and 

 identical in coloration, except that three, instead of only 

 two, basal joints of the antenna are red. Those organs, 

 however, are not stout and compact, but slender and loosely- 

 jointed, with a club composed of three joints only. The 

 sides of the prothorax are strongly rounded in front and
