ovate, and there being no white i)nl)escencc at the dorsal carina. On the elytra 

 both the white and black markings are restricted in nnmber; the sutural space 

 bears some white dots, but all its black spots are suppressed ; the white lateral spot 

 situated behind the shoulder is circular and wider than one interspace. The sterna 

 bear conspicuous and sharply defined white spots. The abdomen is coloured like 

 the sterna ; the pubescence at the bases of the segments is not white, but there is 

 a rounded spot near the base of segments 2 — 4, about half-way between the centre 

 and the lateral row of white spots. The second foretarsal segment has hardly 

 any wjiite jiubescence at the base, and the white colouring is also not much in 

 evidence on segments 7 and 8 of the antenna.

Kina-Balu, N. Borneo : 1 ?. 



A shorter and broader species than .1/. chiUreni. The apical transverse 

 groove of the metasternum is abnost obsolete in between the midco.xae, being here 

 distinctly angulate. The transverse fold behind the groove of the mesosternum is 

 narrower than in M. childreiii, euspilus and atopus., and the groove behind the 

 forecoxae deeper.

A robust sj)ecies. The metasternum has no groove at the apex between the 

 midcoxae. The mesosternum is rather coarsely punctured in front of the coxae on 

 the neck-like portion fitted into the prothorax. 



The pair described by me as whitehead i (1895), from North Luzon, appears to 

 be a variety, jierhaps a geographical one, of M. pupa. 



The above examjile from Mindoro, the only one I have seen, is more elongate 

 than the specimens we have from other places, and the two grooves of the pronotum 

 are a trifle deeper. 



Tiic mesostcrnal process is rather strongly convex in the sjiecimens from tlie 

 I'hilippiiie and Talaut Islands, with the exception of the above examples from Luzon 

 and Mindanao. 



Mecotropis Lac. (18(37). 



The genus consists of three sections, which are ai)pareMtIy well-detincd. The 

 van de Poll collection contains examples of tlie majority of the species. 



A. Median groove of rostrum cimtinued on the frons ; anterior 

 margin of eye straight.

 Occurs also on Buru.
