OF PHYTOPHAGOUS COLEOPTEEA. 345 



the basal margin, halfway between the suture and humeral callus, 

 and running downwards and somewhat obliquely inwards as far 

 as the deflesed apical portion oftbe elytron ; the third commences 

 at the base just within tbe humeral callus, its anterior third 

 curving move strongly inwards than the former one, until it nearly 

 reaches the second ridge, the two on their middle third running 

 nearly contiguous and parallel to each other, being connected by 

 ill-defined transverse costse ; at the commencement of its lower 

 third it diverges, running obliquely outwards, and is lost on 

 the surface of the outer disk nearly at a level with the apex of the 

 second costa; close to the suture, halfway between its middle 

 and apex, is an obtuse tuberosity. Pygidium broadly ovate-rotun- 

 date, truncate at the base, plane, deeply punctured, faintly exca- 

 vated on either side at the base and towards the apex.

Head deeply punctured, nigro-piceous, variegated with fulvo- 

 piceous ; vertex and front with a slightly irregular space on 

 either side, the median surface concave ; antennae with the seven 

 outer joints compressed and dilated, nigro-piceous, the four lower 

 ones pale piceous. Thorax deeply punctured, covered on either 

 side with large, irregular, pale piceous, wart-like protuberances ; 

 disk gibbous, the gibbosity obtuse, covered with coarse, raised, 

 pale piceous rugae, which, form an irregular network on its sur- 

 face. Elytra strongly punctured, irregularly strigose, and covered 

 with coarse, irregular, strongly raised, pale piceous lines, which, ana- 

 stomose and form a loose network over the surface ; here and there 

 at their points of junction they are still more strongly elevated, 

 and form ill-defined tuberosities ; one of these, more distinct and 

 transversely compressed, is placed near the suture below its 

 middle ; there are also several others strongly raised and well 

 defined near the- apex of each elytron,
