1. Small species, length 1.3-1.7, pronotum characteristically with five small round black dots, one at each humeral angle, a median one near posterior margin, and a pair more anteriorly near the median line. An additional ill defined pair medially of the humeral spots may be present. Hemielytra typically with brown transverse bands in the middle and posteriorly which, however, may be absent in pale specimens, head pattern typically with a median brown stripe only ( Fig. 1 ) .......................... P. liturata
