 conf ertim minus fortiter prothorace magis fortiter nee erebre, 

 elytris sat fortiter subseriatim, prepygidio subtiliter nee

 manifeste arcuatim emarginato ; fronte late longitudinaliter 

 concavo ; prothorace postice obsolete eanaliculato ; elytris 

 sat fortiter geminato-striatis ; tibiis anticis extus obtuse 

 3-dentatis ; tarsis validis, posticorum articulis basalibus 2 

 sat sequalibus ; antennis 9-articulatis.

 This species is closely allied to L. concolor, Er., and L. collaris, 

 Macl. The latter difiers from it inter alia by its brownish elytra 

 and more densely frilled prothorax with finer puncturation. L. 

 concolor is a shorter and more ovate species with the prothoracic 

 channel entire or nearly so, the prothoracic puncturation much 

 coarser, the propygidium much more strongly punctulate, the 

 basal joint of the hind tarsi very evidently shorter than the 2nd 

 joint, &c. I suspect that the specimens from N. S. Wales which 

 Sir W. Macleay referred to L. concolor were examples of the 

 insect I am describing.

Late ovalis ; subnitidus ; piceo-niger, antennis palpis elytris 

 tibiis tarsisque obscure rufescentibus ; prothorace basi 

 excepta setis erectis brunneis fimbriate, corpore subtus 

 cinereo-pubescenti ; capite confertim minus fortiter, pro-

 longiori.
