Apparently allied to L. pellepidus Saussure, but differing in the 

 liueato-rugose pronotum, the acute-angulate posterior process of the 

 prouotum, and in the hyaline and unclouded margin of the apex 

 of the wing. 



General form deep, compressed. Head with the fastigium broad 

 and very shallow, the margins but slightly elevated, anteriorly trun- 

 cate; vertex rugose and bearing a central carina, which extends a 

 considerable distance forward on the fastigium ; frontal costa rather 

 broad, expanded above the ocellus, non-sulcate, heavily punctate; 

 eyes ovate, about equal to the infraocular portion of the gense. Pro- 

 notum with the metazone lineato-rugose, the lateral lobes with com- 

 paratively slight rugosities; median carina low, most elevated on 

 the prozona, the transverse sulcus well marked; posterior angle 

 acute, the margin subconcave; posterior angle of the lateral lobes 

 rotundate. Tegraina elongate, the costal field strongly developed 

 basally. Posterior femora robust, the lower carina well developed 

 but not strongly arched ; posterior tibite shorter than the femora.
