useful : —

cinereo vestitus. Antennae fuliginosae, articulis ad basin griseis. Thorax 
fuliginosus grosse punctatus linea dorsali laevi. Elytra sensim attenuata, 
apicibus breviter sinuato-tmncatis, angulis obtusis, ad basin granulato- 
punctatis, quarta parte basali fuliginosa colons margine posteriore retror- 
sum arcuata, reliquis cinereis utrinque fascia interrupta undulata pone 
medium maculaque laterali prope apicem fuscis. Subtus niger nitidus, 
postpectoris lateribus abdominisque apice luteis ; pedibus luteis femorum 
dimidio basali tibiarum tarsorumque apicibus fuscis. Long. 4^ lin. $ .
