Black, pubescent : thorax with the base bisinuated, rufo-testaceous, sometimes 

 with an abbreviated black fascia in the middle of the disc : scutellum black : 

 elytra testaceous, rather deeply punctate-striated, zuith an oblong black spot at 

 the base, and a second large rounded one in the middle of the disc towards the 

 suture : margin of the abdomen testaceous at the apex : legs black, tarsi tes- 

 taceous : posterior femora angulated beneath, with a tooth in the middle, and 

 a series of rigid cilia behind it. 



Variable in colour j being more or less rufo- or pale-testaceous, and the apical 

 spots on the elytra being sometimes united transversely : rarely wanting, but 

 frequently very obscure. 



The most abundant species of the genus throughout the south of 

 England, and I believe also found in the north: it is not uncommon 

 in Norfolk and Suifolk. " Not unfrequenton elms (near Swansea)."
