Very closely allied to Z. Letuisii, Crotch, but, besides the colour- 

 ation, it differs from that species in the thorax being shorter, and the 

 anterior angles being very slightly prominent, whereas in i. Leioisil they 

 are rounded. The punctures of the strife on the elytra are continued 

 to the base, but in L. Leicisli they are almost obliterated in the region 

 of the seutellum. 



The thorax is distinctly narrower than the base of the elytra, 

 slightly convex, slightly narrowed in front, gently rounded at the 

 sides, slightly narrowed before the posterior angles, and not quite as 

 broad at the posterior angles as across the middle of the thorax. 



The punctuation is sparse and delicate, almost obliterated towards 

 the sides.

Extremely close to L. nigritarsis, but distinguished from it by the 

 colour, by the (still very slightly) prominent anterior angles of the 

 thorax, which is slightly less convex. The thorax is slightly narrower 

 than the base of the elytra, very little convex, very slightly narrowed 

 before the posterior angles, as broad at the posterior angles as across 

 the middle of the thorax. The punctuation is distinct, but not very 

 close, less distinct towards the sides.
