 Antennfe 11-joInted, luteo-castaneous. Pronotum nearl}' as broad as 

 the head, scarcely broader posteriorly than anteriorly, of equal length 

 and breadth, quadrate, the posterior angles rounded, and the hind 

 border otherwise straight, slightly tumid anteriorly, with a slight 

 median impressed line, which posteriorly is supplanted by a pair of 

 closely approximated similar lines, rather dark castaneous, broadly 

 bordered on the sides and hind margin with Iuteous, which is sepa- 

 rated from the castaneous by a blackish fuscous belt. Tegmina 

 castaneo-fuscous, darkest next the base, fully half as long again as
