 tho median groove is romplote. Tho posterior intermediate areas of tho metastenium are 

 almo.st unpiincturetl as well as being liairlo.ss ; the lateral areas are thiekly punctured and 

 hairv as in L. Iriijoitup/ionis, their surface being on the sauw level as that of the intermediate 

 areas, an abrupt change of level occurring oidy where they touch the tentnil iri-i 

 Neither in L. tmjouophurus nor in L. inaetjualis are the elytra united.

This sjiecies is easily recognized by the small free forwardly directetl apex of the central 

 tubercle and the aKsenco of inner tJiborcles. The frontal and parietal ridges are ctb.solete 

 or absent. The outer tubercles may bo sinjplc ami symmetrical, or the left one nuiv bo 

 m«>ro or le.ss distinctly d<»ul)le ; the anterior nuirgin of the head is u.sually more or le.ss rough 

 between thcni, this rough area being separated from the rest of the head by a fine ridge 

 or gro<ive. 



Tho pronotum is much broader behind than in front ; its median gnntve is indi.stinct ; 

 it is with«>ut punctures except in the posterior angles (including the true scars, though 

 other unpuncturetl depressions may be pre.sont near then>), which are densely hair)' 

 and jjuncturod. The scutollum boars two longitudinal linos of fine punctures. The 

 niesothoracic opistenia are punctured except in tho posterior angles. The mesostonuim 

 is .smooth and poli.shed ; its tH-ars are distinct, but very .small and le.ss close to the margin 

 than usual. The mctastemum rejjcmblea that of L. trigonoplwrHs. The grooveu of the 

 elytra are deep but unpuncturwl.
