Parum breve, brunueo-nigrum, uitidum ; capita utrinque carinato : 

 thorace subaeneo, dense et parum profuude piinctato. in medio 

 valde dentato ; elytris punctato-striatis ; antennis articulis l°-6"

L. 2 mill. 



This species is rather larger than L. tomaroides, and like 

 it has one very prominent tooth on the middle of the lateral 

 edge; hut the chief difference is in the anternia^, the four 

 apical joints are nearly black, and the 3-jointed club mucii 

 more robust.

Breve, brunneo-nigrum, nitidum ; capite sparse punctato, utrinque 

 carinato ; thorace lateribus in medio valde dentato ; elytris in 

 medio latioribus ; antennis pedibusque brunneis. 



L. lf-2 mill. 



Rather short, brownish black, shining ; the head carinate 

 on either side over the eyes and as far as the antennee, not 

 closely punctured, especially between the eyes ; the thorax 

 closely and more coarsely punctured than the head, the 

 second lateral denticulation from the base is at the middle of 

 the thoracic margin and is very prominent, two anterior 

 teeth obsolete; the elytra widest in the middle, rather 

 browner than the thorax, punctate-striate ; the antenna? are 

 slender and relatively shorter than others of this series, and 

 are with the legs pale brown. 



Resembles a species of Corticaria or Tomarus.
