Burmese specimens belong to the form called platijmelus, 

 in which the mandibles of well-dcvclopcd males are relatively

 indistinguishable.

 tubercles ])laced transversely in the middle. The canthus 

 extends far beyond the middle of the eye but is not prominent. 

 The pr())(()tH)n is shining, with the sides strongly punctured, 

 the punctures dense and rugose externally and extending 

 along the basal margin, 'i'here is a (h)uble series of [)unctures 

 in the middle of the pronotum, generally enclosing a narrow 

 oval area. The lateral margin is gently rounded, the lateral 

 angle not distinct. The scutellum bears a few fine ])unctures. 

 The elytra have al)out twelve deep grooves, confluently and 

 unequally ])unctured, with narrow shining intervals. The 

 grooves are obliterated at the sides and a{)ices. whicli arc
