tate, narrow, sides strongly sinuate posteriorly, basal angles 

 reflexed and sharply rectangular; elytra strongly striate, inter- 

 stices convex, glabrous, minutely punctate, third tripunctate. 

 Wholly testaceous. 



fe^Head rather longer than broad (1-7 x 1-6 mm.), impunctate; 

 front depressed, biimpressed before eyes; space between frontal 

 impressions and sides obsoletely carinate; eyes prominent; sides 

 strongly consti-icted to neck, swollen and sloping obliquely behind 

 eyes; a wide foveiform impression on each side behind eyes above 

 postocular prominences. Prothorax not perceptibly wider than 

 head with eyes, not broader than long (1-8 x 1-8 mm.), hardly 

 wider across base than apex, lightly declivous to sides on anterior 

 half, longitudinally impressed on each side posteriorly at width 

 of peduncle (the space between these impressions and margin 

 depressed), transversely rugulose near sides, Itevigate on disc; 

 sides lightly rounded on anterior two-thirds, widely sinuate at 

 posterior fourth, a little outturned before basal angles ; apex 

 strongly emarginate; anterior angles rounded; median line deep, 

 reaching from base to apex; border reflexed (greatly so posteriorly, 

 hardly so near anterior angles). Elytra parallel (6 x 3-5 mm.), 

 nearly twice as wide as prothorax ; base sloping roundly to 

 shoulders; striis crenulate; third interstice tripunctate, fifth with 

 a strongly marked setigerous puncture about posterior third and 

 two much finer near anterior third. 



Length 10, breadth 3-5 mm.

Allied to X. infascata, Chaud., from which (and from X. 

 anr/ustula, Chaud.) it differs by its larger size, paler colour, 

 impunctate head and prothorax, much finer puncturation of 

 elytral interstices, &c. ; from X. satelles, Blkb., another allied 

 species, it difters by the want of piceous vittje on the elytra, and 

 the presence of setigerous punctures on the fifth interstice.
