 well-marked triangular shield, the rear and side is regularly striate punc- 

 tate, the colour from the punctures more or less suffusing the intervals, 

 the exterior standard spots also show faintly in livid, marginal stria lightly 

 curved and barely sinuate, lobe well developed, with a strong row of 

 marginal punctures, body below very dark brown, with the usual parts 

 picked out in dark red, legs light reddish yellow, with light ends to femurs
