234 AMITHAO ALBOPICTUS. 



The epimera are thickly punctured; the scutellum is 

 small and very acute. 



The elytra are rather parallel sided , rounded at the apex , 

 obtusely produced at the suture , the suture strongly raised ; 

 each elytron with two strong costae , ending both into the 

 apical callus , which is not much prominent , rounded ; 

 ornated with numerous small irregular transverse impres- 

 sions , filled with a white tomentum , between these a few 

 large punctures may be observed , which become rather 

 numerous along the outer margins , the apical portion is 

 finely strigose. 



The pygidium is transverse, closely and finely striated. 



The mesosternal process is slightly produced , straight , 

 obtuse; the breast and the sides of the abdomen are covered 

 with large but shallow punctures ; the abdomen is deeply and 

 broadly sulcated ; all the tibiae are unarmed ; the pubes- 

 cence is black. 



This species is probably allied to A. Lafertei Thorns. , a 

 species I do not possess. Compared with A. cavifrons Burm. 

 there are striking differences , that species having the head 

 very deeply excavated , the excavation sharply bordered , 

 the median callus terminated anteriorly by a strong trans- 

 verse ridge, the clypeus longer and more rounded, much 

 more elevated in front and at the sides, the pygidium 

 more pointed, less transverse, the legs more robust, with 

 the anterior tibiae of the cT bidentate and the middle and 

 hinder legs also provided with a strong sharp tooth. How- 

 ever without possessing a larger material and knowing 

 the other sex, I think it not advisible to separate it from 

 this genus.
