 minutely sculptured, with three ill-defined, approximated, longitudinal 

 lines on the middle, connecting with a well-defined carina which mar-

 and obliquely striated, the posterior truncation depressed and rugose. 

 Wings bright yellow, with the apical margins rather broadly margined

 with cinereous pubescence, the tarsi piceous or rufo-piceous, especially 

 at tips. Abdomen shining, closely punctured on the sides, more 

 sparsely on the disk of the segments, the apical margins of which are

 the base truncate and excavated, the verge of the truncation carinate ;

 ous, the two or three basal joints ferruginous. Thorax : sides of the
