 sides ; suture straight ; forehead triangularly concave and de- 

 clivous, the depressed portion rather strongly punctate, a 

 transverse impressed line between the eyes ; the latter large 

 (much larger than in L. pallipes, Blackb.) ; antennae extending 

 to the base of prothorax, joint 3 slightly longer than 4, 4-10 

 cupuliform, gradually widening to the apex 8 , 11 oval longer 

 and wider than 10. Profit max transverse and rather flat, 

 truncate at apex and base, anterior angles widely rounded, 

 posterior obtuse and defined, sides evenly rounded without 

 sinuation, very narrowly bordered and channelled, base also

 at apex : striate-punctate, with ten striae on each elytron, the 

 striae well impressed and containing close half-hidden punc-

Hah. — Western Australia: Poreongereny (?) (H. Giles). 



A single male specimen sent some years ago by Mr. Giles 

 (with an indistinct pencil locality label) is evidently distinct 

 from all described species, though nearest L. pall i pes, Blackb. 

 The last has its under-side black, or dark-bronze, with a much 

 more convex thorax, and the elytral striae less deep. Type in 

 ■author's collection.
