l''>6 MONOHAMMÜS VERSTEEGII, 



from the base of the spines, and a few small points are 

 naked. On the elytra a few similar dots are present along 

 the suture and lateral margins; along the suture they are 

 placed in a single longitudinal row , along the lateral mar- 

 gins however in two alternatiny longitudinal rows. On the 

 under surface three pairs of naked dots may be observed : 

 the first on the sides of the prosternum , the second in 

 the anterior external angles of the metathoracical episterni , 

 the third on the middle of the . lateral margins of the 

 metasternum; moreover the metasternum shows a naked 

 longitudinal impressed line on the middle. 



The face transverse , the lower lobes of the eyes a little 

 higher than broad , the front triangularly emarginated be- 

 tween the antennary tubers ; a fine naked line from the 

 middle of the anterior margin of the clypeus ending a 

 little before the anterior margin of the prothorax. The 

 scape of the antennae sub-cilindrical , as long as two thirds 

 of the length of the 3rd joint , the cicatrix sharply defi- 

 ned and closed; the 4th joint a little shorter than the 

 3rd; the 5th- 10th almost inconspicuously increasing in 

 length, the apical (11th) joint a little more than twice 

 the length of the 10th , slightly curved near the apex. 



The prothorax a little broader than long , with a widely 

 interrupted transverse linear groove a little behind the 

 front margin , another curved faint one a little more back- 

 wards , and two narrow ones before the basal margin ; the 

 latter as well as the basal grooves slightly bisinuate; the 

 lateral spines are strong and acute and obliquely directed 

 upwards. The scutellum triangular, broadly rounded at 

 the tip. 



The elytra at the base much broader than the protho- 

 rax , the shoulders and apices rounded. 



The pro- and mesosternum rounded, neither produced 

 nor tuberculated. 



The described specimen was captured on Mount Bari- 

 san (± 2000 feet) in the District of Singkarah ').
